Rails sending AJAX response with a textarea - ruby-on-rails

I am using the following form:
<%= form_for(#document, :remote => true) do |f| %>
<%= f.label :asset, "Document to Upload" %><br />
<%= f.file_field :asset, :class => "behaves", "data-behave" => "passValueOnChange", "data-recipient" => "#campaign_document_name" %>
<%= f.label :name, :class => 'required' %><br />
<%= f.text_field :name, :required => true %>
<%= f.submit "Upload Document", :class => "button" %>
<% end %>
to submit to the following controller:
def create
#document = CampaignDocument.new(params[:campaign_document])
#campaign.documents << #document
respond_to do |format|
format.js
end
end
which should return the following create.js.erb:
<%= remotipart_response do %>
<% unless #document.errors.any? %>
$('.tablewrapper').html( '<%= escape_javascript(render :partial=>'documents_table') %>' );
alertify.success("File Updloaded");
<% else %>
<% #document.errors.each do |attr, msg|%>
alertify.error("<%= msg %>",10000);
<% end %>
<% end %>
<% end %>
but the response is wrapped in a textare tag. Which is pretty odd:
<textarea data-type="text/javascript" response-code="200">
$('.tablewrapper').html('{code for HTML ommited for brevity}');
alertify.success("File Updloaded");
</textarea>
Note
Other, similar styled AJAX functions on the same installation are not behaving this way.

Ruby on rails Simple Search not displaying results

Hey guys im developing a rails application that stores quotes in a database and then allows you to search through the quotes using a simple search. I have implemented the search form but the results do not appear and I cant figure out why.
controller:
class BasicsController < ApplicationController
def quotations
#quotations = Quotation.all
if params[:search]
#quotations = Quotation.search(params[:search]).order("created_at DESC")
else
#quotations = Quotation.all.order("created_at DESC")
end
if params[:quotation]
#quotation = Quotation.new( params[:quotation] )
if #quotation.save
flash[:notice] = 'Quotation was successfully created.'
#quotation = Quotation.new
end
elsif
#quotation = Quotation.new
end
if params[:sort_by] == "date"
#quotations = Quotation.order(:created_at)
else
#quotations = Quotation.order(:category)
end
end
end
model:
class Quotation < ApplicationRecord
def self.search(search)
where("author_name LIKE ? OR quote LIKE ?", "%#{search}", "%#{search}")
end
end
view:
<%= form_tag basics_quotations_path, :method => 'get' do %>
<p>
<%= text_field_tag :search, params[:search], placeholder: "Search Quotations" %>
<%= submit_tag "Search", :name => nil %>
</p>
<% end %>
<h3>Quotations</h3>
<ul>
<% for quotation in #quotations %>
<li><%= h quotation.author_name %>: <%= h quotation.quote %></li>
<% end %>
</ul>
<br/>
<% if params[:sort_by] == "date" %>
<%= link_to "Sort by category", :action => :quotations, :sort_by => :category %>
<% else %>
<%= link_to "Sort by date", :action => :quotations, :sort_by => :date %>
<% end %>
<hr/>
<h3>New quotation</h3>
<%= form_for #quotation, :url => { :action => :quotations } do |form| %>
<fieldset>
<legend>Enter details</legend>
<div class="form_row">
<%= form.label :author_name %>
<%= form.text_field :author_name, :size => 20, :maxlength => 40 %>
</div>
<div class="form_row">
<%= form.label :category %>
<% #cats = [] %>
<% Quotation.select('DISTINCT category').map(&:category).each do |element| %>
<% #cats << element %>
<% end %>
<%= form.select(:category,options_for_select([[#cats[0],1],[#cats[1], 2], [#cats[2],3]])) %>
</div>
<div class="form_row">
<%= form.label :new_category%>
<%= form.text_field :category , :size =>20 , :maxlength => 40 %>
</div>
<div class="form_row">
<%= form.label :quote %>
<%= form.text_area :quote, :rows => 2, :cols => 40, :maxlength => 500 %>
</div>
</fieldset>
<p>
<div class="form_row">
<%= form.submit 'Create' %>
</div>
</p>
<% end %>
routes:
Rails.application.routes.draw do
get 'basics/quotations'
resources :quotation, :quotations
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
end
You've got EVERYTHING in one action, which isn't great. You might want to review some of the simple rails tutorials available.
On the subject of search in particular, note the last four lines of your method...
if params[:sort_by] == "date"
#quotations = Quotation.order(:created_at)
else
#quotations = Quotation.order(:category)
end
So regardless of the results of your seach, you'll replace #quotations at that point with all quotations in either created_at or category order.
It is not wise to place all the stuffs into a single action,your action should be very clear and well defined.But you can achieve what you wanted to do like this.
class BasicsController < ApplicationController
before_action :new_quotation, only:[:search_quotations,:index,:quotations]
def search_quotations
respond_to do |format|
if params[:search]
#quotations = Quotation.search(params[:search]).order("created_at DESC")
else
#quotations = Quotation.all.order("created_at DESC")
end
if params[:sort_by] == "date" && quotations.present?
#quotations = #quotations.order(:created_at)
else
#quotations = #quotations.order(:category)
end
format.js{}
end
end
def quotations
if params[:quotation]
#quotation = Quotation.new( quotation_params)
if #quotation.save
flash[:notice] = 'Quotation was successfully created.'
end
redirect_to root_path
end
end
def index
#quotations = Quotation.all
end
private:
def new_quotation
#quotation = Quotation.new
end
//If you are using rails4 for later version then go for this line.
def quotation_params
params.require(:quotation).permit(:author_name, :quote,:category)
end
end
You need to actually separate the logic into above actions and where 'quotation' action is meant for creating a new quotation and 'seach_quotation' is for searching all the quotations and it should returns js response cause we are going to need this while rendering a partial '_list.html.erb'.
Your view(index.htm.erb) will be looking like this.
<div>
<%= form_tag basics_search_quotations_path, :method => 'get', remote: true do %>
<p>
<%= text_field_tag :search, params[:search], placeholder: "Search Quotations" %>
<%= submit_tag "Search", :name => nil %>
</p>
<% end %>
</div>
#This partial will be used for refreshing the quotations list via remote true feature for searching and sorting.
<div id="quotation_list">
<%= render 'basics/shared/list',{quotations: #quotations} %>
</div>
br/>
<% if params[:sort_by] == "date" %>
<%= link_to "Sort by category", :action => :search_quotations, :sort_by => :category, :remote => true %>
<% else %>
<%= link_to "Sort by date", :action => :search_quotations, :sort_by => :date, :remote => true %>
<% end %>
<hr/>
<h3>New quotation</h3>
<%= form_for #quotation, :url => { :action => "quotations", :controller => "basics" } do |form| %>
<fieldset>
<legend>Enter details</legend>
<div class="form_row">
<%= form.label :author_name %>
<%= form.text_field :author_name, :size => 20, :maxlength => 40 %>
</div>
<div class="form_row">
<%= form.label :category %>
<%= form.select(:category,options_for_select(['Love','Romance','Sadness'])) %>
</div>
<div class="form_row">
<%= form.label :category%>
<%= form.text_field :category , :size =>20 , :maxlength => 40 %>
</div>
<div class="form_row">
<%= form.label :quote %>
<%= form.text_area :quote, :rows => 2, :cols => 40, :maxlength => 500 %>
</div>
</fieldset>
<p>
<div class="form_row">
<%= form.submit 'Create' %>
</div>
</p>
<% end %>
Here is the partial that display the list of Quotations /basics/shared/_list.html.erb
<h3>Quotations</h3>
<ul>
<% for quotation in #quotations %>
<li><%= h quotation.author_name %>: <%= h quotation.quote %></li>
<% end %>
</ul>
Here is the routes you need to add routes.rb
resources :quotation, :quotations
get "basics/search_quotations" => "basics#search_quotations"
post "basics/quotations" => "basics#quotations"
root 'basics#index'
Instead of performing any calculation in views its better to perform it in controller/model if needed.
so instead of this following line in your view
<% #cats = [] %>
<% Quotation.select('DISTINCT category').map(&:category).each do |element| %>
<% #cats << element %>
<% end %>
<%= form.select(:category,options_for_select([[#cats[0],1],[#cats[1], 2], [#cats[2],3]])) %>
You can create an instance variable let's say #categories or something and use it like this
<%= form.select(:category,options_for_select(#categories)) %>
And last but not the least we have to have a search_quotations.js.erb because we are sending ajax request for fetching the search result and returning 'js' response.
$("#quotation_list").html("<%= escape_javascript(render('basics/shared/list', {quotations: #quotations })) %>")

Extend forms without page reload, rails

I'm searching for a solution to extend my form without page reload.
First I tried to render a partial with coffee or javascript, but escape_javascript didnt work.
Here's the view
<%= form_for #recipe = current_user.recipes.build do |f| %>
<%= f.label :name, "Recipe Name" %>
<%= f.text_field :name %>
<%= button_to "Add Ingredient", '#', class: "btn btn-lg btn-primary", id: "add" %>
<p></p>
<%= f.submit class: "btn" %>
<% end %>
The form above should be extented with following partial by every click on the button
<div id="recipe-ingredients">Quantity
<%= f.fields_for :quantities, #recipe.quantities.build do |quantity| %>
<%= render 'quantity_fields', f: quantity %>
<% end %>
</div>
_quantity_fields
<%= f.label :amount, "Amount:" %>
<%= f.text_field :amount %>
<%= f.collection_select(:ingredient_id, Ingredient.all, :id, :name) %>
This approach did not work (recipes.js.erb)
$(document).ready(function() {
$("#add").click(function() {
$("p").append("<%= escape_javascript
render(:partial => 'quantities') %>");
});
});
There's a workaround (see below) but I'm searching for a better solution.
$(document).ready(function() {
$("#workout-week").append(<%= escape_javascript(
Haml::Engine.new(File.read(File.join(Rails.root,'app/views',
'_show_period.html.haml'))).render(Object.new, period: #period)) %>);
});
A second approach is to write following lines in Coffee or JavaScript:
<%= f.fields_for :quantities, #recipe.quantities.build do |quantity| %>
<%= f.label :amount, "Amount:" %>
<%= f.text_field :amount %>
<%= f.collection_select(:ingredient_id, Ingredient.all, :id, :name) %>
<% end %>
I'm a newbie so take this with a grain of salt, but have you tried using render :foo instead of redirect_to :foo in the appropriate controller function?
I solved it with cocoon
<%= form_for #recipe do |f| %>
<div class="field">
<%= f.label :name %>
<br/>
<%= f.text_field :name %>
<%= f.fields_for :quantities do |quantity| %>
<%= render 'quantity_fields', :f => quantity %>
<% end %>
<div class="links">
<%= link_to_add_association 'add', f, :quantities %>
</div>
</div>
<%= f.submit %>
<% end %>

How do I re-populate form fields when validation fails?

This is the erb template:
<div id='recipe-form'>
<% if #recipe.errors %>
<div id='errors'>
<% #recipe.errors.messages.each do |field, messages| %>
<div class='error'>
<div class=field'><%= field %></div>
<div class='messages'>
<ul>
<% messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
</div>
<% end %>
</div>
<% end %>
<%= form_for #recipe, :html => {:multipart => true}, :url => '/recipes' do |f| %>
<%= f.label :title, 'title' %>
<%= f.text_field :title %>
<div id="photo-upload">
<%= file_field :photo0, :image, :id => 0 %>
</div>
<div id='existing-photos'>
<% recipe.photos.each do |photo| %>
<div id='<%= photo.id %>'>
<img src='<%= photo.image.url(:thumb) %>' />
<ul>
<li>
<%= link_to 'delete',
recipe_photo_url(
:recipe_id => #recipe.slug,
:id => photo.id
),
:method => :delete,
:remote => true
%>
</li>
</ul>
</div>
<% end %>
</div>
<%= f.label :body, 'body' %>
<%= f.cktext_area :body, :ckeditor => {:width => "500"} %>
<%= f.label :tags, 'tags (comma separated)' %>
<%= text_field_tag :tags %>
<%= submit_tag 'submit' %>
<% end %>
</div>
This is the create action:
def create
#recipe = Recipe.new(params[:recipe])
photo_keys = params.keys.select{|k|k.match(/^photo/)}
#photos = []
photo_keys.each do |photo_key|
#photos << Photo.new(params[photo_key])
end
#recipe.tags = Tag.parse(params[:tags])
#recipe.author = current_user
if #recipe.save &&
#photos.all?{|photo|photo.save}
#photos.each do |photo|
photo.recipe_id = #recipe.id
photo.save
end
flash[:notice] = 'Recipe was successfully created.'
redirect_to recipe_url(#recipe.slug)
else
flash[:error] = 'Could not create recipe. '
flash[:error] += 'Please correct any mistakes below.'
render :action => :new
end
end
And this is the new action:
def new
#recipe = Recipe.new
end
I read that if I use form_for as I am using above, the fields will be re-populated automatically.
When I inspect #recipe.errors from within the erb template, I can see that the errors generated by create are also available when the new action is rendered, but the fields do not re-populate.
I'm actually not sure about what render action: does but what I do and works is: Instead of rendering the action just render the template using render :new.
You need to set the same instance variables (those with #), which you already in your create action.

remember form tag input values

I'm trying to create a filter form that user selects dates and sources. The problem is after clicking submit button, in the new page i see that input values are empty. Is there a way to make form remember its values ? Thanks.
<%= form_tag products_path, :method => 'get' do %>
<%= text_field_tag :from %>
<%= text_field_tag :to %>
<% Source.all.each do |source| %>
<%= check_box_tag "sources[]", source.id %>
<%= source.name %><br />
<% end %>
<%= submit_tag "Submit", :name => nil %>
<% end %>
controller
def index
#from = params[:from] ? params[:from].to_datetime : (Time.now-3.day)
#to = params[:to] ? params[:to].to_datetime : (Time.now)
#sources = params[:sources] ? params[:sources] : 1..6
#products = Product.where(:source_id => #sources, :created_at => #from.beginning_of_day..#to.end_of_day)
end
Can't you use the value and checked options from these tags? Here is an example :
<%= form_tag products_path, :method => 'get' do %>
<%= text_field_tag :from, #from %>
<%= text_field_tag :to, #to %>
<% Source.all.each do |source| %>
<%= check_box_tag "sources[]", source.id, #sources.include?( source.id ) %>
<%= source.name %><br />
<% end %>
<%= submit_tag "Submit", :name => nil %>
<% end %>

How to pass parameters between controller actions without using sessions?

For example, if in my 'edit.html.erb' file I have this:
<%= form_for(#pjt_user) do |f| %>
...
<%= fields_for(:new_pjt_user) do |b| %>
<%= b.label :new_password %>
<%= b.text_field :new_password %>
<% end %>
...
<% end %>
How can I "pre-populate"/"fill" the field 'new_password' (in 'fields_for(:new_pjt_user)') passing a parameter with a render action? I aim to avoid to store password in session.
Instead of render :action you have to use render :template so you can use the :locals hash:
render :template => "pjt_users/new", :locals => { :default_password => DEFAULT_PASSWORD }
and
<%= fields_for(:new_pjt_user) do |b| %>
<%= b.label :new_password %>
<%= b.text_field :new_password, :value => default_password %>
<% end %>
