Prefill form from associated object on error in Rails - ruby-on-rails

I have a Post that has_many :comments and a Comment that belongs_to :post.
On /posts/:id (the post show method) I render a form where users can leave comments.
It all works, validations, tests and posting is just fine. Only thing missing is how to re-render the POSTed data on validation errors.
The (simplified) code for this is:
#app/controllers/posts_controller.rb
class PostsController < ApplicationController
def index
#posts = Post.all_published(params[:page])
#title = "Blog"
end
def show
#post = Post.where({:published => true}).find(params[:id])
#comment = Comment.new(:post => #post)
#title = #post.title
end
end
#app/controllers/comments_controller.rb
class CommentsController < ApplicationController
def create
#comment = Comment.new(params[:comment])
puts #comment
if #comment.save
flash[:notice] = 'Comment was successfully created.'
redirect_to(#comment.post)
else
flash[:notice] = "Error creating comment: #{#comment.errors}"
redirect_to(#comment.post)
end
end
end
#app/views/posts/show.haml
.html renders Post contents.
- form_for #comment do |f|
= f.hidden_field :post_id
= f.text_area :body
= f.text_field :name
.some more fields.
I expect the solution to be either in some magical declaration in the comments_controller.rb, part
else
flash[:notice] = "Error creating comment: #{#comment.errors}"
redirect_to(#comment.post)
end
Or in the PostsController.show where I prepare the #comment. Should I set that #comment conditional and fill it with some magic variable on errors?
Or did I make some entirely different mistake?

If you redirect, that data is usually lost, thats why in most cases in create create actions you would have noticed that in the false scenario, render not redirect_to.
So instead you could just try,
flash[:notice] = ""Error creating comment: #{#comment.errors}"
render :template => "posts/show"
#post = #comment.post
# you may need to pre-populate the instance variables used inside PostsController#show

Rails 4 form_for nested resources issue

I have researched similar questions however I don't feel link they have addressed my particular issue:
Rails form_for results in POST instead of PUT when trying to edit
form_for with nested resources
I'm a novice with Rails (using Rails 4.2.5) an am attempting my first application. My issue is two fold: (1) When a user goes to edit a user story the fields of the form do not populate with previously inputted data (2) When the form is resubmitted, a new entry is created, opposed to editing the old data.
I have a feeling that my form_for for user_stories/edit.html.erb is the issue. When I take out the .build method from the form I get the following error message:
undefined method `to_key' for #UserStory::ActiveRecord_Associations_CollectionProxy:0x007f456a759138>
The projects/_form.html.erb for my project's view does not have the .build method and functions correctly. However the only way I can get the `user_stories/_form.html.erb form to work is if I attach the build method.
Here is my code:
user_story.rb
class UserStory < ActiveRecord::Base
belongs_to :project
belongs_to :user
include RankedModel
ranks :row_order
end
project.rb
class Project < ActiveRecord::Base
has_many :user_stories
belongs_to :user
end
routes.rb
Rails.application.routes.draw do
devise_for :users
resources :projects do
resources :user_stories
end
end
resources :user_stories do
post :update_row_order, on: :collection
end
root 'welcome#index'
end
user_stories/_form.html.erb
<%= form_for([#project, #user_story.build]) do |f| %>
<div class="form-group">
<p>As a ...</p>
<%= f.text_field :param1, placeholder: "type of user", class: "form-control" %>
</div>
<div class="form-group">
<p>I want ...</p>
<%= f.text_field :param2, placeholder: "desired functionality", class: "form-control" %>
</div>
<div class="form-group">
<p>so that...</p>
<%= f.text_field :param3, placeholder: "reason for desired functionality", class: "form-control" %>
</div>
<div class="actions">
<%= f.submit class: "btn btn-primary" %>
</div>
<% end %>
user_stories_controller.rb
class UserStoriesController < ApplicationController
before_action :set_project
before_action :set_user_story, except: [:create]
def index
#user_story = #project.user_stories.rank(:row_order).all
end
def update_row_order
#user_story.row_order_position = user_story_params[:row_order_position]
#user_story.save
render nothing:true # this is a POST action, updates sent via AJAX, no view rendered
end
def create
#user_story = #project.user_stories.create(user_story_params)
redirect_to #project
end
def new
end
def destroy
if #user_story.destroy
flash[:success] = "User story deleted"
else
flash[:error] = "User story could not be deletd"
end
redirect_to #project
end
def complete
user_story.update_attribute(completed_at, Time.now)
redirect_to #project, notice: "User story completed functionality complete"
end
def update
respond_to do |format|
if #project.user_stories.update(#project, user_story_params)
format.html { redirect_to project_path(#project), notice: 'User story was successfully updated.' }
format.json { render :show, status: :ok, location: #user_story }
else
format.html { render :edit }
format.json { render json: #user_story.errors, status: :unprocessable_entity }
end
end
end
def edit
#project = Project.find(params[:project_id])
#user_story = #project.user_stories(params[:id])
end
def show
end
private
def set_project
#project = Project.find(params[:project_id])
end
def set_user_story
#user_story = #project.user_stories(params[:id])
end
def user_story_params
params[:user_story].permit(:param1, :param2, :param3, :row_order_position)
end
end
There are just a few changes needed (tweaks, really), and I'll go through them top-to-bottom.
1) before_action :set_user_story
This will use the param[:id] to find the proper #user_story model object and automatically make it available to the proper methods. In this case it's being excepted for :create, but should also exclude other methods that don't have an :id in the route. Use this instead:
before_action :set_user_story, except: [:index, :new, :create]
This will solve (or prevent) some annoying and persistent ActiveRecord failures.
2) The index action
In this method, the name of the variable is non-standard by Rails naming conventions. The variable is currently singular, but represents a list of UserAction model object, which typically uses a plural name. Use this, instead:
def index
#user_stories = #project.user_stories.rank(:row_order).all
end
This change will cause a break in the app/views/user_stories/index.html.erb view, where any use of the #user_story variable would need to be changed to #user_stories. Keeping with naming conventions has many immediate and long-term benefits, so it's worth making the extra effort to change this to be consistent.
Note: the index action typically doesn't have a singular model object to work with, as this action is used to provide a list of the model objects.
3) The new action
The new action is used to create and initialize a new model object for editing. As the before_action :set_user_story is no longer being called for the new action, the #user_story model object has to be created here. This code will do that correctly:
def new
#user_story = UserStory.new
#user_story.project = #project
# Set other important default values for display now
end
And at this point, you should be able to successfully create a new UserStory model object, ready to be edited by the user.
4) The edit action
As the before_action :set_user_story handler is already being called for the edit action, there's no need to query for #user_story from within the body of the edit action; that line can be removed:
def edit
#project = Project.find(params[:project_id])
end
This will actually fix the original issue that was reported, as this form of find will (unfortunately for this situation) return multiple records, which means that you get a collection back, and not a single record. This is the actual cause of this error message:
undefined method `to_key' for #UserStory::ActiveRecord_Associations_CollectionProxy:0x007f456a759138>
Assigning the #user_story within the edit action overwrote the value that had previously been assigned from the before_action handler, and replaced it with an improper query result.
5) The complete action
The complete action is a custom member action, which means that it depends on the :id, just like many of the other actions. The code is almost correct, except that the user_story variable used within the body of the method is actually missing the #; this is originally retrieved by the before_action handler.
def complete
#user_story.update_attribute(completed_at, Time.now)
redirect_to #project, notice: "User story completed functionality complete"
end
It's likely that this method had not been called yet during testing, as the edit action was an upstream test that failed. This should work when you get to testing this method.
6) Teh codez
Changing those few details will finalize the UserStoriesController, which was in pretty great shape to begin with. Adding in those changes, this is the final controller code:
class UserStoriesController < ApplicationController
before_action :set_project
before_action :set_user_story, except: [:index, :new, :create]
def index
#user_stories = #project.user_stories.rank(:row_order).all
end
def update_row_order
#user_story.row_order_position = user_story_params[:row_order_position]
#user_story.save
render nothing:true # this is a POST action, updates sent via AJAX, no view rendered
end
def create
#user_story = #project.user_stories.create(user_story_params)
redirect_to #project
end
def new
#user_story = UserStory.new
#user_story.project = #project
# Set other important default values for display now
end
def destroy
if #user_story.destroy
flash[:success] = "User story deleted"
else
flash[:error] = "User story could not be deleted"
end
redirect_to #project
end
def complete
#user_story.update_attribute(completed_at, Time.now)
redirect_to #project, notice: "User story completed functionality complete"
end
def update
respond_to do |format|
if #project.user_stories.update(#project, user_story_params)
format.html { redirect_to project_path(#project), notice: 'User story was successfully updated.' }
format.json { render :show, status: :ok, location: #user_story }
else
format.html { render :edit }
format.json { render json: #user_story.errors, status: :unprocessable_entity }
end
end
end
def edit
#project = Project.find(params[:project_id])
end
def show
end
private
def set_project
#project = Project.find(params[:project_id])
end
def set_user_story
#user_story = #project.user_stories(params[:id])
end
def user_story_params
params[:user_story].permit(:param1, :param2, :param3, :row_order_position)
end
end

In Rails How to display errors in my comment form after I submit it?

I have a very straight-forward task to fulfil --- just to be able to write comments under posts and if the comments fail validation display error messages on the page.
My comment model uses a gem called Acts_as_commentable_with_threading, which creates a comment model after I installed.
On my post page, the logic goes like this:
Posts#show => display post and a form to enter comments => after the comment is entered, redisplay the Post#show page which has the new comment if it passes validation, otherwise display the error messages above the form.
However with my current code I can't display error messages if the comment validation fails. I think it is because when I redisplay the page it builds a new comment so the old one was erased. But I don't know how to make it work.
My codes are like this:
Comment.rb:
class Comment < ActiveRecord::Base
include Humanizer
require_human_on :create
acts_as_nested_set :scope => [:commentable_id, :commentable_type]
validates :body, :presence => true
validates :first_name, :presence => true
validates :last_name, :presence => true
# NOTE: install the acts_as_votable plugin if you
# want user to vote on the quality of comments.
#acts_as_votable
belongs_to :commentable, :polymorphic => true
# NOTE: Comments belong to a user
belongs_to :user
# Helper class method that allows you to build a comment
# by passing a commentable object, a user (could be nil), and comment text
# example in readme
def self.build_from(obj, user_id, comment, first_name, last_name)
new \
:commentable => obj,
:body => comment,
:user_id => user_id,
:first_name => first_name,
:last_name => last_name
end
end
PostController.rb:
class PostsController < ApplicationController
before_action :authenticate_user!, except: [:index, :show]
def show
#post = Post.friendly.find(params[:id])
#new_comment = Comment.build_from(#post, nil, "", "", "")
end
end
CommentsController:
class CommentsController < ApplicationController
def create
#comment = build_comment(comment_params)
respond_to do |format|
if #comment.save
make_child_comment
format.html
format.json { redirect_to(:back, :notice => 'Comment was successfully added.')}
else
format.html
format.json { redirect_to(:back, :flash => {:error => #comment.errors}) }
end
end
end
private
def comment_params
params.require(:comment).permit(:user, :first_name, :last_name, :body, :commentable_id, :commentable_type, :comment_id,
:humanizer_answer, :humanizer_question_id)
end
def commentable_type
comment_params[:commentable_type]
end
def commentable_id
comment_params[:commentable_id]
end
def comment_id
comment_params[:comment_id]
end
def body
comment_params[:body]
end
def make_child_comment
return "" if comment_id.blank?
parent_comment = Comment.find comment_id
#comment.move_to_child_of(parent_comment)
end
def build_comment(comment_params)
if current_user.nil?
user_id = nil
first_name = comment_params[:first_name]
last_name = comment_params[:last_name]
else
user_id = current_user.id
first_name = current_user.first_name
last_name = current_user.last_name
end
commentable = commentable_type.constantize.find(commentable_id)
Comment.build_from(commentable, user_id, comment_params[:body],
first_name, last_name)
end
end
comments/form: (this is on the Posts#show page)
<%= form_for #new_comment do |f| %>
<% if #new_comment.errors.any? %>
<div id="errors">
<h2><%= pluralize(#new_comment.errors.count, "error") %> encountered, please check your input.</h2>
<ul>
<% #new_comment.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<% end %>
I would instead use nested routes to create a more restful and less tangled setup:
concerns :commentable do
resources :comments, only: [:create]
end
resources :posts, concerns: :commentable
This will give you a route POST /posts/1/comments to create a comment.
In your controller the first thing you want to do is figure out what the parent of the comment is:
class CommentsController < ApplicationController
before_action :set_commentable
private
def set_commentable
if params[:post_id]
#commentable = Post.find(params[:post_id])
end
end
end
This means that we no longer need to pass the commentable as form parameters. Its also eliminates this unsafe construct:
commentable = commentable_type.constantize.find(commentable_id)
Where a malicous user could potentially pass any class name as commentable_type and you would let them find it in the DB... Never trust user input to the point where you use it to execute any kind of code!
With that we can start building our create action:
class CommentsController < ApplicationController
before_action :set_commentable
def create
#comment = #commentable.comments.new(comment_params) do |comment|
if current_user
comment.user = current_user
comment.first_name = current_user.first_name
comment.last_name = current_user.last_name
end
end
if #comment.save
respond_to do |format|
format.json { head :created, location: #comment }
format.html { redirect_to #commentable, success: 'Comment created' }
end
else
respond_to do |format|
format.html { render :new }
format.json { render json: #comment.errors, status: 422 }
end
end
end
private
# ...
def comment_params
params.require(:comment).permit(:first_name, :last_name, :body, :humanizer_answer, :humanizer_question_id)
end
end
In Rails when the user submits a form you do not redirect the user back to the form - instead you re-render the form and send it as a response.
While you could have your CommentsController render the show view of whatever the commentable is it will be quite brittle and may not even provide a good user experience since the user will see the top of the post they where commenting. Instead we would render app/views/comments/new.html.erb which should just contain the form.
Also pay attention to how we are responding. You should generally avoid using redirect_to :back since it relies on the client sending the HTTP_REFERRER header with the request. Many clients do not send this!
Instead use redirect_to #commentable or whatever resource you are creating.
In your original code you have totally mixed up JSON and HTML responses.
When responding with JSON you do not redirect or send flash messages.
If a JSON POST request is successful you would either:
Respond with HTTP 201 - CREATED and a location header which contains the url to the newly created resource. This is preferred when using SPA's like Ember or Angular.
Respond with HTTP 200 - OK and the resource as JSON in the response body. This is often done in legacy API's.
If it fails do to validations you should respond with 422 - Unprocessable Entity - usually the errors are rendered as JSON in the response body as well.
Added.
You can scrap your Comment.build_from method as well which does you no good at all and is very idiosyncratic Ruby.
class PostsController < ApplicationController
before_action :authenticate_user!, except: [:index, :show]
def show
#post = Post.friendly.find(params[:id])
#new_comment = #post.comments.new
end
end
Don't use line contiuation (\) syntax like that - use parens.
Don't:
new \
:commentable => obj,
:body => comment,
:user_id => user_id,
:first_name => first_name,
:last_name => last_name
Do:
new(
foo: a,
bar: b
)
Added 2
When using form_for with nested resources you pass it like this:
<%= form_for([commentable, comment]) do |f| %>
<% end %>
This will create the correct url for the action attribute and bind the form to the comment object. This uses locals to make it resuable so you would render the partial like so:
I'm assuming your form_for submits a POST request which triggers the HTML format in CommentsController#create:
def create
#comment = build_comment(comment_params)
respond_to do |format|
if #comment.save
make_child_comment
format.html
format.json { redirect_to(:back, :notice => 'Comment was successfully added.')}
else
format.html
format.json { redirect_to(:back, :flash => {:error => #comment.errors}) }
end
end
end
So, if #comment.save fails, and this is an HTML request, the #create method renders create.html. I think you want to render Posts#show instead.
Keep in mind that if validations fail on an object (Either by calling save/create, or validate/valid?), the #comment object will be populated with errors. In other words calling #comment.errors returns the relevant errors if validation fails. This is how your form is able to display the errors in #new_comment.errors.
For consistency, you'll need to rename #new_comment as #comment in the posts#show action, otherwise you'll get a NoMethodError on Nil::NilClass.
TL;DR: You're not rendering your form again with your failed #comment object if creation of that comment fails. Rename to #comment in posts, and render controller: :posts, action: :show if #comment.save fails from CommentsController#create
I have figured out the answer myself with the help of others here.
The reason is that I messed up with the JSON format and html format (typical noobie error)
To be able to display the errors using the code I need to change two places ( and change #comment to #new_comment as per #Anthony's advice).
1.
routes.rb:
resources :comments, defaults: { format: 'html' } # I set it as 'json' before
2.
CommentsController.rb:
def create
#new_comment = build_comment(comment_params)
respond_to do |format|
if #new_comment.save
make_child_comment
format.html { redirect_to(:back, :notice => 'Comment was successfully added.') }
else
commentable = commentable_type.constantize.find(commentable_id)
format.html { render template: 'posts/show', locals: {:#post => commentable} }
format.json { render json: #new_comment.errors }
end
end
end

Tree comments Ruby on Rails

Trying to implement a tree-like comments on the site via a gem - acts-as-commentable-with-threading.
Comments are excellent and are displayed on the site when I visit a site under the user (implemented via the gem devise).
But when trying to view pages anonymously, naturally, I receive an error that id is not may be due to the elements onto a blank.
This is my controller recipes_controller.rb:
class RecipesController < ApplicationController
before_action :authenticate_chef!, except: [:index, :show]
def show
#recipe = Recipe.find(params[:id])
#comments = #recipe.comment_threads.order('created_at desc')
#user_who_commented = current_chef
#new_comment = Comment.build_from(#recipe, #user_who_commented.id, "")
end
...
comments_controller.rb:
class CommentsController < ApplicationController
before_action :authenticate_chef!
def create
commentable = commentable_type.constantize.find(commentable_id)
#user_who_commented = current_chef
#comment = Comment.build_from(commentable, #user_who_commented.id, body)
respond_to do |format|
if #comment.save
make_child_comment
format.html { redirect_to(:back, :notice => 'Comment was successfully added.') }
else
format.html { render :action => "new" }
end
end
end
...
recipe.rb:
class Recipe < ActiveRecord::Base
acts_as_commentable
...
In views (recipes/show.html.erb) I put this render :
<%= render partial: "comments/template", locals: {commentable: #recipe, new_comment: #comment} %>
I think that you may need in the controller to create something like a design if ... else for those who just browse the site, because the default at this point in the show method is set current_chef, because of what and error.
You need to handle the special case in view(probably comment template) for anonymous visit. Cause then current_chef would be nil. So where you're using it in view and controller, handle that properly.
A tip: You don't need to assign current_chef to any instance variable actually. It's already a helper method. You can call it directly from view.

Flash messages in rails 4 not showing (within partial, within modal)

The problem in brief: I'm working on a rails 4 app (4.1.8) and I'm trying to get flash[:notice] and flash[:alert] to show up under a form.
Two controllers: landingpage_controller and contacts_controller. The landingpage_controller serves a static landingpage through its show action and the contacts_controller has new and create actions, to store the contacts in a db table.
On the static landingpage, a modal with id="contact-modal" contains a partial with a simple_form_for #contact (see below). Upon submittal of the form, a db-entry is not created if the fields are not all filled out and a db-entry is created if the fields are filled out. However, no flash messages are displayed.
Wanted output:
Ideally the partial would re-load without leaving/closing the modal, with either: a success message and an empty form or a alert message and the form as it was upon submittal. How do I do this?
The controller: app/controllers/contacts_controller.rb
class ContactsController < ApplicationController
def new
#contact = Contact.new
render layout: "contact"
end
def create
#contact = Contact.new
respond_to do |format|
if #contact.save
flash[:notice] = "Success"
format.js
else
flash[:alert] = "Error"
format.js
end
end
end
private
def contact_params
params.require(:contact).permit(:email, :structure, :message_content)
end
end
The form: app/views/contacts/_new.html.haml
= simple_form_for #contact, html: { id: "contact-form"} do |c|
= c.input :email
= c.input :structure
= c.input :message_content
= c.button :submit
.messages-container
= if flash[:notice]
%p
= flash[:notice]
= if flash[:alert]
%p
= flash[:alert]
Routes:
resources :contacts, only: [:new, :create]
I'm aware that a partial reload probably involves AJAX. I've read several StackOverflow questions on this but have not been able to figure it out. See here, here and these two blog-posts: jetthoughts, ericlondon.
Your help is very much appreciated
There are several problems in your code:
views, that start with underscore are called partials and are not full actions, but just parts of reusable view code (you don't redirect to them, instead you use render since you usually don't want a full page reload.
1.1 Rename your _new.html.haml to _form.html.haml
2.1 Create a new view new.html.erb(I guess you have that already, otherwise your new action might not work properly) with content = render 'form'
From what I understand you don't want the modal to close, just to render a form after successful submission or if there is an error.
In that case:
1.create a create.js.erb file in your views/contacts folder
create.js.erb
$("#your_modal_id").html("<%= j( render 'form') %>")
2. change your create action
def create
#contact = Contact.new(contact_params)
respond_to do |format|
if #contact.save
flash[:notice] = "Success"
format.js
else
flash[:alert] = "Error"
format.js
end
end
end
to your form add remote: true
WARNING: This will leave your form filled in even if it is successful.

Hope it helps, and I hope I didn't forget anything

Rails 4 Form Partial Not Rendering Submitted Data Immediately

Probably a very simple problem I'm overlooking. I'm building a feature similar to Facebook's "home" page for logged in users. A user can post topics in one form, and that form works perfectly.
There is a comment form under each posted topic. When a user enters a comment and clicks the submit button the comment is created, but it is not shown unless I manually refresh the page. I can't see what I'm doing wrong here.
_form.html.haml
= form_for [topic, Comment.new], remote: true do |f|
.form-group
= f.text_area :body, rows: 2, class: 'form-control', placeholder: "Make a comment"
= f.submit "Post", class: 'f-button primary f-fw-bold post-btn'
I have tried using #topic for this form as well but get the error: undefined method `comments_path'
comments_controller.rb
class CommentsController < ApplicationController
def create
puts "TOPICS PARAMS",params[:topic_id]
#topic = Topic.find(params[:topic_id])
#comments = #topic.comments
#comment = current_user.comments.build( comment_params )
#comment.topic = #topic
#new_comment = Comment.new
if #comment.save
flash[:notice] = "Comment was created."
redirect_to topics_path
else
flash[:error] = "There was an error saving the comment. Please try again."
redirect_to topics_path
end
end
private
def comment_params
params.require(:comment).permit(:body, :topic_id)
end
end
All of this is rendered in the topics#index path, so here is the topics controller as well.
topics_controller.rb
class TopicsController < ApplicationController
def index
#topics = Topic.order(created_at: :desc)

In the index.html.haml file I call the partial like this:
= render partial: 'comments/form', locals: { topic: topic, comment: #comment}
You are using remote: true for your form. So the submit will trigger an Ajax request. A javascript response will be returned, but no HTML will be updated by default.
You will need to sprinkle some javascript to update the HTML yourself: bind a callback to the ajax:success event, or use a js view (e.g. app/views/comments/create.js.erb).
Have also a look at Turbolinks 3 (still in development), which can reduce the amount of custom javascript required for partial page updates.
Your problem likely lies here ...
= form_for [topic, Comment.new], remote: true do |f|
Try this instead
= form_for #new_comment, url: {controller: 'comments', action: 'create'}, method: "post", remote: true do
and be sure your config/routes.rb looks something like this
get "/some-path", to: "comments#create"
post "/some-path", to: "comments#create"
I had to use javascript to get better control over the form and data. So I made a topic.coffee file with this:
$ ->
$('.new_comment').on 'submit', (event) =>
form = $(event.target).closest('form')
topicCommentsId = form.attr('action').replace(/\//g, '_').substring(1)
owningCommentsSection = $('#' + topicCommentsId)
formData = form.serialize()
$.post form.attr('action'), formData, (data) =>
extractedBody = $(data.substring(data.indexOf('<body')))
topicComments = extractedBody.find('#' + topicCommentsId)
owningCommentsSection.html(topicComments.html())
form.find('[name="comment[body]"]').val('')
location.reload();
return false
I removed the remote: true from my form as well and identify each topic in my index.html.haml with this:
.f-grid-row.topic_comments{id: "topics_#{topic.id}_comments"}
- topic.comments.each do |comment|
- if comment.topic_id == topic.id || comment.post_id == topic.id
