Hi, I''m just starting out writing a RoR application, and I have a
couple of questions...
Lets say I have a model
class Questionnaire < ActiveRecord::Base
has_many :categories
end
I''ve understood that one can reference a variable from the model/table
in a form using e.g.
<%= text_field ''questionnaire'', ''title''
%>
But what if I want to do the same with the related model Category?
Using
<%= text_field(''category'', ''caption'')
%>
does not give any information about which questionnaire the category
belongs to. Are there any neat tricks to do this within the framework,
lets say something like
<%= text_field(''questionnaire_category_123'',
''caption'') %>
or must I write some custom code to do this?
And what about validations: using validates_* now only reports that
something is wrong within Categories when i try to do
"some_questionnaire.save", but does not give me any specific
information about what failed to validate. How can I get that sort of
information?
Any help is greatly appreciated!
Best,
Arnfinn
