Save and update multiple tables/models

Hello everybody.

I’m trying to make the save and update 2 tables and I can not do the same. Use Ruby 4 Rails 2.

Table I and Table cases valves. Need to save four valves in each case.

Now I can list both on the same view of the cordon with the codes below:

Model Caso

class Caso < ActiveRecord::Base

attr_accessible :name

has_many :valva, :dependent => :destroy, :autosave => true

accepts_nested_attributes_for :valva

end

``

Model valva

class Valva < ActiveRecord::Base

attr_accessible :caso_id, :valva_tipo

belongs_to :caso

end

``

Routes

resources :casos do

resources :valvas

end

``

casos_controller.rb

def new

@caso = Caso.new

4.times do

@caso.valva.build

 end

end

``

_form.html.erb de Caso

<%= form_for(@caso) do |f| %>

     ...  

<%= f.label :name %><br>

<%= f.text_field :name %>

<%= f.fields_for :valva do |v| %>

 <div class="field">
          <%= v.label :valva_tipo %>

   <%= v.number_field :valva_tipo %>

 </div>

<% end %>

<%= f.submit %>

<% end %>

Hi,

Can you post the error you’re getting and the log?

Thanks

You need to mark :valva_attributes as accessible too or Active Record won’t let it through. If that doesn’t fix things, could you give more details as to how it’s not working?
