Let’s say I have a simple RESTful scaffold named: product

and the new and edit forms contain something like:

\<% form\_for( @product ) do |f| %\>

\<%= f.text\_field :name %\>

\<% end %\>

Everything is cool and working. Now, let’s say I want to use a  
belongs\_to in product.rb

class Product

belongs\_to :some\_other\_model, blah, blah…

end

Is it possible to do something on the product form to reference  
some\_other\_model and capture form field values??

I’m thinking something along the lines of:

\<% form\_for( @product ) do |f| %\>

\<%= f.text\_field :some\_other\_model.other\_name %\>

\<% end %\>

or whatever the syntax would be…

Thanks

you would wrap these in a fields\_for block. ie

\<% form\_for( @product ) do |f| %\>

\<%= f.text\_field :some\_other\_model.other\_name %\>

 \<% fields\_for :some\_other\_model do |o| %\> \<%= o.text\_field o.other\_name %\> \<% end %\> \<% end %\>
