Question

This functionality used to work but has suddenly stopped and I have no idea why. I’ve made changes before I ran the tests but, having retraced my steps I don’t know what has changed. Can a fresh pair of eyes tell me why this is saving the posts but not the locations?

Model Post.rb

class Post < ActiveRecord::Base
 attr_accessible :title, :body, :tag_list, :locations_attributes
 has_and_belongs_to_many :locations
 accepts_nested_attributes_for :locations, :reject_if => :all_blank
end

*Controller Posts_controller.rb *

class PostsController < ::Blogit::ApplicationController

...     

def new
  @post = current_blogger.blog_posts.new(params[:post])
  @location = @post.locations.build
end

def update
  @post = current_blogger.blog_posts.find(params[:id])
  if @post.update_attributes(params[:post])
    redirect_to @post, notice: 'Blog post was successfully updated.'
  else
    render action: "edit"
  end
end

def create
  @post = current_blogger.blog_posts.new(params[:post])
  if @post.save
    redirect_to @post, notice: 'Blog post was successfully created.'
  else
    render action: "new"
  end
end

end

*View _form.html.erb*

<%= nested_form_for(@post, :html=> {:multipart => true, :class=> "new_blog_post", :id=> "new_blog_post"}) do |f| %>

 ...

<%= field do %>
  <%= f.text_field :title, placeholder: "Give your post a title", :class=>"span12" %>
<% end %>
<%= field do %>
  <%= f.text_area :body, placeholder: "Write something here...", :id=>"blog-text", :class=>"span12" %>
 <% end %>

<%= field id: "new_blog_post_tag_field" do %>
  <%= f.label :tag_list, "Tags" %>
  <%= f.text_field :tag_list, placeholder: "tag one, tag two, etc..." %>
<% end %>

<%= f.label :search_locations, "Add locations to your post" %>
   <%= render :partial => 'search_locations', :locals => { :f => f }  %>

 <p><%= f.link_to_add "Add a location", :locations %></p>

<%= actions do %>
<%= f.submit "Submit", :class=>"btn", :disable_with => 'Uploading Image...' %> or 
<%= link_to("cancel", @post.new_record? ? root_path : post_path(@post)) %>

<% end %>

<% end %>

*Form Partial _search_locations.html.erb*

 <%= f.fields_for :locations do |m| %>


 <%= m.text_field :name,:class=>"localename", :id=>"appendedInput", :placeholder=> "Name of the location", :autocomplete => "off" %>


 <span class="add-on"><%= m.link_to_remove do %><i class='icon-trash'></i></span><%end%>


 <% end %>

And the actual submission in the logs comes up as this:

Started PUT "/blog/posts/51-hong-kong" for 127.0.0.1 at 2012-11-06 17:41:00 +0000

Why is this saving the post but not the locations info?

Answer 1

Solved it, it was a stray bit of code in the model.

Thanks for all your help!
