Why is this happening?
submitted_quiz.rb
class SubmittedQuiz < ActiveRecord::Base
belongs_to :user
belongs_to :quiz
has_many :submitted_answers, :dependent => :destroy
accepts_nested_attributes_for :submitted_answers, :reject_if => -> (a) {a[:content].blank? }, :allow_destroy => true
end
Just didn't read up on nested resources paths. The correct path should have been user_submitted_quiz_path(#user, submitted_quiz).

I'm trying to create "group posts" that are connected to a "user group" and a user. The first line of my create method is failing with this error:
Couldn't find UserGroup with 'id'=
I've been looking at blog building tutorials thinking that my "group post" is acting like a comment but instead of being attached to an article it's attached to a "user group".
I'm pretty new to Rails so it could be simply a syntax issue. Any advise would be appreciated.
Here is the group post create method:
def create
#user_group = UserGroup.find(params[:user_group_id])
#group_post = current_user.group_posts.new(group_post_params)
if #group_post.save
respond_to do |format|
format.html {redirect_to user_group_path(#user_group), notice: "Group Post created!"}
end
else
redirect_to user_group_path(#user_group), notice: "Something went wrong."
end
end
private
def group_post_params
params.require(:group_post).permit(:content, :post_type, :user_group_id)
end
Here is the user group model:
class UserGroup < ActiveRecord::Base
has_many :group_members, dependent: :destroy
has_many :members, through: :group_members, source: :user
has_many :group_posts, dependent: :destroy
validates :name, presence: true, length: {minimum: 5}
validates :searchable, presence: true, length: {minimum: 5}
def owners
members.includes(:group_members).where('group_members.owner = ?', true)
end
def regular_users
members.includes(:group_members).where('group_members.owner = ?', false)
end
end
Here is the group post model:
class GroupPost < ActiveRecord::Base
include PublicActivity::Model
belongs_to :user
belongs_to :user_group
validates :user_id, :presence => true
validates :content, :presence => true
end
And finally the routes:
Rails.application.routes.draw do
devise_for :users, controllers: {registrations: 'registrations'}
root 'pages#home'
resources :users, only: [:index, :show]
resources :friendships, only: [:create, :destroy, :accept] do
member do
put :accept
end
end
resources :posts, only: [:create, :edit, :update, :destroy]
resources :group_posts, only: [:create, :edit, :update, :destroy]
resources :activities, only: [:index] do
member do
put "upvote" =>"activities#upvote"
end
end
resources :user_groups do
resources :group_posts
resources :group_members
end
end
Here is the form partial submitting the group post:
<div class="posts-panel">
<%= form_for(#group_post) do |f| %>
<%= render 'partials/error_messages', object: f.object %>
<div class="form-group">
<%= f.text_area :content, placeholder: "Compose new post...", class: "form-control" %>
</div>
<div class="form-group">
<%= f.select :post_type, [['Request', 'request'],['Report', 'report']], {}, {class: "form-control"} %>
</div>
<div class="form-group">
<%= hidden_field_tag :user_group_id, #usergroup.id %>
<%= f.submit "Post", class: "btn btn-primary" %>
</div>
<% end %>
</div>
Complete Params:

The user_group_id was not inside the params hash. Adding the following line to the create method solved the issue:
#group_post.user_group = #user_group
This is my simple web app for following user, it has an error, please help me :)
I can't insert following_id into database. I'm stuck with it

When i check Relation.all in rails console, the following_id has been insert, but when i check (as curent_user account)user.following - i see nothing, no following_id. I think something wrong in relation_controller at "current_user.following << follow".
I just can follow my current_user but it's ridiculous :)). So, please help me !!!!!!
You need to sanitize parameters before you can put things into the database.

I hope I am not asking an obvious question/ wont get down voted to hell for this.I am working on rails app and I am getting a "param is missing or the value is empty" error.
I have an event and questions that have already been created and I am using a nested form to allow the user to answer all the questions at once.
I am using rails 4
Models
class Event < ActiveRecord::Base
belongs_to :user
has_many :questions
accepts_nested_attributes_for :questions, allow_destroy: true
end
class Question < ActiveRecord::Base
belongs_to :user
belongs_to :event
has_many :answers
accepts_nested_attributes_for :answers, allow_destroy: true
end
class Answer < ActiveRecord::Base
belongs_to :user
belongs_to :question
end
Routes.rb
Rails.application.routes.draw do
root 'home#index'
devise_for :users, path_names: {sign_in: "login", sign_out: "logout"}, controllers: {omniauth_callbacks: "omniauth_callbacks"}
resources :answers
resources :users, only: [:new, :create]
resources :questions do
resources :answers #-> domain.com/questions/1/answers/new
end
resources :events, only: [:index, :new, :show, :update] do
patch ":id", action: :index
collection do
get :favorite
get "question/:id", action: :question
end
end
get 'users/new', to: 'users#new'
post 'users/new', to: 'users#create'
get 'events/favorite', to: 'events#favorite', via:[:get], as: 'favorite'
post 'events/:id' => 'events#update'
get 'answers/new' => 'answers#new'
get 'events/question' => 'events#question'
end
answers controller
class AnswersController < ApplicationController
def new
#event = Event.find(params[:id])
#answer = Answer.new
end
def show
end
def create
#answer = Answer.new(answer_params)
#answer.save
redirect_to events_path, notice: "Answered Questions"
end
private
def answer_params
params.require(:answer).permit(:response, :question, :event, :user, :event_id, :question_id, :user_id)
end
end
This is where my issue lies. Originally I had a very generic nested from a la http://railscasts.com/episodes/196-nested-model-form-revised but I switched the form_for down to the #answer because that is whats being created and switched to a button_to because the submit button was not writing the answer to the DB.(I believe it was trying to trigger something with #event )
<h1>New answers</h1>
<%= fields_for #event do |f| %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<%= f.fields_for :questions do |b| %>
<p>
<%= b.text_field :poll%><br />
<%= form_for #answer do |x| %>
<%= x.text_field :response %>
<% end %>
</p>
<% end %>
<%= button_to "New", action: "create"%>
<% end %>
<%= link_to 'Back', answers_path %>
Please let me know if you need anymore code or have any questions
Thanks!
UPDATE
I have reworked my code based off this blog post http://iroller.ru/blog/2013/10/14/nested-model-form-in-rails-4/
now I am running the update through the events controller or at least I'm trying to.
The code is as follows, the error im getting now is

I'm currently developing an app which allows users to post from their own account, but if they're an administrator of a group or venue, they can also post as that entity. I'm struggling converting the polymorphic association ideas from some of the other questions out there as generally they're all based around being able to comment on multiple things and not from multiple things.
I think my main issue is that I have my user's post form on the homepage, so it does not have an ID in the URL.
My post controller looks like this:
class PostsController < ApplicationController
before_action :authenticate_user!, only: [:create, :destroy]
before_filter :load_postable
def index
end
def new
#post = Postabe.posts.new(post_params)
end
def create
#post = #postable.posts.build(post_params)
if #post.save
flash[:success] = "Post created!"
redirect_to root_url
else
#feed_items = []
render 'static_pages/home'
end
end
def destroy
#post.destroy
redirect_to root_url
end
private
def post_params
params.require(:post).permit(:content)
end
def load_postable
resource, id = request.path.split('/')[1, 2]
resource_name = resource.singularize.classify
if resource_name == "User"
#postable = current_user
else
#postable = resource_name.constantize.find(id)
end
end
end
and my _post_form.html.erb partial:
<%= form_for ([#postable, #postable.post.new]), remote: true do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field">
<%= f.text_area :content, placeholder: "Create a Post..." %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
my related routes:
devise_for :users, :controllers => { :omniauth_callbacks => "omniauth_callbacks", :registrations => "registrations" }
resources :users, :only => [:index] do
member do
get :favourite_users, :favourited_users
end
resources :posts
end
resources :venues do
resources :posts
end
resources :groups do
resources :posts
end
Models as follows:
class Post < ActiveRecord::Base
belongs_to :postable, polymorphic: true
end
class User < ActiveRecord::Base
has_many :posts, as: :postable, dependent: :destroy
end
class Venue < ActiveRecord::Base
has_many :posts, as: :postable, dependent: :destroy
end
class Group < ActiveRecord::Base
has_many :posts, as: :postable, dependent: :destroy
end
It seems that I keep getting the error
Couldn't find Post without an ID
but I don't know why it's looking for a Post ID if it's not been created yet. Any help would be appreciated!
You have before_filter :load_postable in your controller. By default it will run for all the actions in your controller, even when the id is not specified. The error is thrown by #postable = resource_name.constantize.find(id), id is nil for index method.
Change this line to:
before_filter :load_postable, except: [:index]
My link_to in my view is going to a completely different "show.html.erb" than I'd like it to. I'm basically trying to understand why the "link_to #exhibit is linking to an "Investigation" profile. I think it may have to do with my routes file or the fact that its a "belong to" relationship...but can't seem to get it workin...what should that link_to be?
UPDATE: (AS PER BROIS QUESTION)
The missing misbehaving link_to is in the <%= link_to #exhibit do %> in show.html.erb
MY EXHIBIT.RB (MODEL)

I appreciate the help...if i need to post any more info just let me know
IN YOUR : app/contorollers/exhibits_controller.rb

IN YOUR : app/views/exhibits/show.html.erb
<%= link_to investigation_exhibit_path(#investigation, #exhibit) do %>
Maybe, I think.
