Ruby on Rails模型中的关系

Question

I have a View called View_CrossReference in Sybase. I want to create Model for this view. This table has a column called Answer .

I have an another table and model called SurveyXref . In this table i have a column called Answer_No .

I want to create a relationship between these models and get the data from Answer column from View_CrossReference and display into my grid in SurveyXref page.

Answer 1

IN view_crossreference model

has_one :survey_xrefs, :primary_key => :answer, :foreign_key => :answer_no

In survey_xrefs model

belongs_to :view_crossreference, :primary_key => :answer , :foreign_key => :answer_no

now simply in controller u can access

v.view_crossreference.answer

Answer 2

Without "Model", means you have created table via stand alone migration. Could you please show me your code for better understanding?
