Rails howto: custom value field in collection_select

Posted on 10/11/2007 by Webdevotion

Very easy this one:

Contact.rb ( Model )
... def name_and_company @name_and_company = name + " - " + contact.company.name end ...

Usage ( note the use of :name_and_company )
<%= form.collection_select(:contact_id, @contacts, :id, :name_and_company ) %>

Controller:

def custom_name
@custom_name = ‘test’
end

Error:

undefined method `custom_name’ for #

It works nevertheless.
I confused Model with Controller.
Sorry for the noise…
