Rails - Mar 2008 - Validation error handling on related models

I have 2 models, entity and client.  Entity has_one client and client
belongs_to entity.

Entity has attributes name and legal_name.  Entity also has an unique
index on (lower(name)).  The pKey for both is the conventional Rails id.
Client has a fKey constraint on entity_id and is indexed in entity_id.

In controllers/clients_controller.rb I have:

  # GET /clients/new
  # GET /clients/new.xml
  def new
    @client = Client.new
    @entity = Entity.new

    respond_to do |format|
      # new.html.erb
      format.html { render :template =>
''clients/edit.html.erb'' }
      format.xml  { render :xml => @client }
    end
  end

In models/entity.rb I have the following validation:

  validates_presence_of   :entity_name,
    :message => "The name may not be blank.

The file views/clients/edit.html.erb has the following code:

<h1>Editing client <%= @entity.id unless @entity.new_record?
%></h1>

<%= error_messages_for :client %>

<% form_for(@client) do |cu| %>
  <% fields_for @entity do |en| %>
    Name <%= en.text_field :entity_name %>
    <br />Legal name <%= en.text_field :entity_legal_name %>
    <br />Legal form <%= en.text_field :entity_legal_form %>
  <% end %>

  <br />Credit Policy <%= cu.text_field :client_credit_policy %>
  <br />Credit Terms  <%= cu.text_field :client_credit_terms %>
...
  <p>
    <%= cu.submit "Update" if @client.active? %>
  </p>
<% end %>

<%= link_to ''Show'', @client %> |
<%= link_to ''Back'', clients_path %>

When I try and add a new client - entity pair with a blank name, instead
of getting a nicely formated error on top of the entry page I get this:


We''re sorry, but something went wrong.

We''ve been notified about this issue and we''ll take a look at
it
shortly.


and in the log I get this:

Much SQL truncated
...
ActiveRecord::RecordInvalid (Validation failed: Entity legal name The
legal name
 may not be blank., Entity name The name may not be blank.):

    c:/usr/lib/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/
transactions.rb:120:in `rollback_active_record_state!''

...

Why am I not getting the default validation error displayed on the edit
page?

Thanks,

Can you show the truncated SQL?  Also the parameters from the log file 
sent to the #update method and also the content of the #update method...

Name <%= en.text_field :entity_name %>

should be something like:

Name <%= en.text_field :name %>

hth

p.s.  a great way to debug this is to stick a debugger statement at the 
top of your controller method, gem install ruby-debug and then start 
your mongrel server like this: script/server webrick -u

or if you don''t have mongrel.. What.. you don''t have
mongrel????!!!!

I do not think so.  The attribute is indeed entity_name for in the 
migration I have:

class CreateEntities < ActiveRecord::Migration

  def self.up
    create_table :entities do |t|

      t.string  :entity_name,                 :null => false,
                :limit  => 30
      t.string  :entity_legal_name,           :null => false,
                :limit  => 120
      t.string  :entity_legal_form,           :null => false,
                :limit  => 4

Whoops.. you are right, my bad!  I still believe however that the data 
is not coming into your controllers correctly so the missing fields trip 
your validators.

I would just debug it as I suggested above and the error will come 
screaming out at you..

Well, perhaps I did not make myself clear to begin with.  I am testing 
the validators and so the data is indeed missing.  The problem I am 
having here is that the flash notice is not displaying on the edit page 
as I expect.

This code is at a very rudimentary stage and there are a number of 
intricate dependencies that I have yet to code. So I am taking care that 
all the straight-forward error handling is working as I expect and that 
my assumptions are checked against reality at an early stage.

Thanks for the heads up on this.  I have installed it and found a decent 
write up on it at:

Nope.

I was poking around in the controllers/application.rb and removed 
(commented) some code thus:


  # def rescue_action(exception)
  #   if exception.class.to_s ==
''ActionController::RoutingError''
  #     logger.error "404 #{exception}"
  #     @pageTitle = ''Not found''
  #     redirect_to ''/404.html''
  #   #  render :template => ''frontpage/render_404'',
:layout =>
''standard'',
  #   #    :status => ''404 Not found''
  #   #  unless ENV[''RAILS_ENV''] ==
''production'' or
request.env[''REQUEST_URI''] ==  ''/test_404''
  #   #    bb_log "Dumping call stack at 404: 
#{request.env[''REQUEST_URI'']}\n"+caller.join("\n   
")
  #   #  end
  #   else
  #     log_error(exception)
  #
  #     if ENV[''RAILS_ENV''] == ''production''
or local_request? == false
  #       ExceptionMailer.deliver_kaboom(exception, self, request)
  #     end
  #     @exception = exception
  #     @pageTitle = "Unexpected error"
  #     message = ''500 Internal error: Support has been
notified''
  #     render :template => ''frontpage/render_500'', :layout
=>
''standard'',
  #       :status => message
  #      redirect_to ''/500.html''
  #   end
  # end

Now the validation failure reports this in the browser:

 ActiveRecord::RecordInvalid in ClientsController#create

Validation failed: Entity legal name The legal name may not be blank., 
Entity name The name may not be blank.

Response

Headers:

{"cookie"=>[],

but when I try to view the backtrace I get this:

  No route matches "/Application-Trace" with {:method=>:get}

My routes,rb says this:

# The routes table below is a waerfall implementation and

  # The priority is based upon order of creation:

  # This route can be invoked with purchase_url(:id => product.id)

  # Sample resource route (maps HTTP verbs to controller actions

  #   map.resources :products

  # Sample resource route with options:

  #     admin.resources :products

  # You can have the root of your site routed with map.root -- just
  # remember to delete public/index.html.
  # map.root :controller => "welcome"

  # See how all your routes lay out with "rake routes"

  # Install the default routes as the lowest priority.
  map.connect '':controller/:action/:id''
  map.connect '':controller/:action/:id.:format''
end


Any guidance is appreciated.
