Rails - Dec 2012 - Dislpaying validation errors from one one model to view of another.

Hi,

I have a model,

class UserComment
belongs_to :user
validates :player_id, :presence => true
validates :comment, :uniqueness => { :scope => :player_id}

partial "comments" from User.
= simple_form_for @user, :html => {:class =>
''comment-form''}, :remote =>
true do |f|
  %fieldset
    = f.fields_for :user_comments do |uac|
      = uac.input :comment, :as => :text, :input_html => {:rows => 5, 
:width => 5}
      .comment-action
        = uac.button :submit, :value => ''Comment'', :class
=> ''btn''


When I click on submit button and if the validation receives any error it 
does not display it on the view. I am not sure where the problem is.

It looks like you''re not outputting your errors on your view.

If you go to your terminal/command line and try the following:

type ''rails c'' to enter the rails console. Here we go do a
quick bit of
testing to see if the errors are being captured.
type ''user = User.new'', this''ll output a new User
object.
type ''user.errors'' If it returns Nil then you have a different
problem
otherwise it''s a case of just displaying your errors.

In your view you could do something like...

<% if @user.errors %>
  <div class="errors">
    <p>There was an error, please see below.</p>
    <ul>
      <% @user.errors.full_messages.each do | msg | %>
        <li><%= msg %></li>
      <% end %>
    </ul>
  </div>
<% end %>

I hope that helps.

I was sending the errors to the view from the controller. I found out that
since the errors where not from the base model (User) so it wasn''t
displaying them. Once I added them to the base using errors.add(:base,
"Error"), it started displaying the errors.
