Validation error handling on related models

Rails
1

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:

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

<%= error_messages_for :client %>

<% form_for(@client) do |cu| %>
<% fields_for @entity do |en| %>
Name <%= en.text_field :entity_name %>

Legal name <%= en.text_field :entity_legal_name %>

Legal form <%= en.text_field :entity_legal_form %>
<% end %>


Credit Policy <%= cu.text_field :client_credit_policy %>

Credit Terms <%= cu.text_field :client_credit_terms %>
…

<%= cu.submit "Update" if @client.active? %>

<% 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

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…

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:

http://blog.nanorails.com/articles/2006/07/14/a-better-rails-debugger-ruby-debug

or if you don’t have mongrel… What… you don’t have mongrel!!!

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:

Response

Headers:

{“cookie”=>[],
“Cache-Control”=>“no-cache”}

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 first URI matched is taken.

ActionController::Routing::Routes.draw do |map|
map.resources :clients

map.connect ‘/clients/:id/deactivate’,

:controller => ‘clients’,

:action => ‘deactivate’,

:requirements => { :id => /\d+/ }

map.connect ‘clients/e/:entity_id’,

:controller => ‘clients’,

:action => ‘edit_from_entity’

The priority is based upon order of creation:

first created -> highest priority.

Sample of regular route:

map.connect ‘products/:id’, :controller => ‘catalog’, :action =>

‘view’

Keep in mind you can assign values other than :controller and

:action

Sample of named route:

map.purchase ‘products/:id/purchase’, :controller => ‘catalog’,

:action => ‘purchase’

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

Sample resource route (maps HTTP verbs to controller actions

automatically):

map.resources :products

Sample resource route with options:

map.resources :products,

:member => { :short => :get, :toggle => :post },

:collection => { :sold => :get }

Sample resource route with sub-resources:

map.resources :products,

:has_many => [ :comments, :sales ], :has_one =>

:seller

Sample resource route within a namespace:

map.namespace :admin do |admin|

# Directs /admin/products/* to

Admin::ProductsController

(app/controllers/admin/products_controller.rb)

admin.resources :products

end

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.
