Rails Nested Forms Not Saving or Validating On Update - ruby-on-rails

Question

I have the following controller:
class Admin::ArticleChangeRequestsController < Admin::ApplicationController
before_action :set_order, only: :index
before_action :set_article_change_request, only: [:edit, :delete]
helper SortClassHelper
protected
def set_order
if params[:column].present?
#column = params[:column]
else
#column = 'created_at'
end
if params[:sort].present?
#sort = params[:sort]
else
#sort = 'desc'
end
#order = #column.to_s + ' ' + #sort.to_s
end
def set_article_change_request
#article_change_request = ArticleChangeRequest.find(params[:id])
end
def article_change_request_params
params[:article_change_request].permit(:title, :change, :article)
end
public
def index
#article_change_requests = ArticleChangeRequest.order(#order).page params[:page]
end
def edit
if request.patch?
if #article_change_request.update(article_change_request_params)
redirect_to :admin_article_change_requests, :flash => { success: t(:article_change_request_updated) }
end
end
end
def delete
if request.post?
if #article_change_request.delete
flash[:success] = t(:article_change_request_deleted)
render :json => { :success => true }
else
render :json => { :success => false }
end
end
end
end
and have added:
accepts_nested_attributes_for :article
in my ArticleChangeRequest model. However whenever I hit Update it does not validate or save the article. Here is my Form:
<%= form_for #article_change_request, { :url => :admin_article_change_request_edit } do |f| %>
<%= render partial: 'form', locals: { f: f } %>
<div>
<%= f.submit t(:update), class: 'submit' %>
</div>
<% end %>
<% if #article_change_request.errors.any? %>
<div class="message errormsg">
<p>
<%= t :there_is %> <%= pluralize #article_change_request.errors.count, t(:error) %>
</p>
</div>
<% end %>
<div class="container">
<%= f.label :title, t(:change_request_title) + ':' %>
<%= f.text_field :title, size: 40, class: 'text' %>
<% unless #article_change_request.errors[:title].blank? then %>
<span class="note error">
<% #article_change_request.errors[:title].each do |e| %>
<% if e == #article_change_request.errors[:title].last %>
<%= e %>
<% else %>

<% end %>
<% end %>
</span>
<% end %>
</div>
<div class="container">

<span class="note error">

<% if e == #article_change_request.errors[:change].last %>

<% else %>

<% end %>
<% end %>
</span>

Can anyone tell me why its not validating or updating?

Answer 1

params[:article_change_request].permit(:title, :change,
:article_attributes => {:category_id, :title, :slug, :article_type})
