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!
