Rails Model inheritance in forms
- by Tiago
I'm doing a reporting system for my app.
I created a model ReportKind for example, but as I can report a lot of stuff, I wanted to make different groups of report kinds. Since they share a lot of behavior, I'm trying to use inheritance.
So I have the main model:
model ReportKind << ActiveRecord::Base
end
and created for example:
model UserReportKind << ReportKind
end
In my table report_kinds I've the type column, and until here its all working.
My problem is in the forms/controllers.
When I do a ReportKind.new, my form is build with the '*report_kind*' prefix.
If a get a UserReportKind, even through a ReportKind.find, the form will build the 'user_report_kind' prefix.
This mess everything in the controllers, since sometimes I'll have params[:report_kind], sometimes params[:user_report_kind], and so on for every other inheritance I made.
Is there anyway to force it to aways use the 'report_kind' prefix?
Also I had to force the attribute 'type' in the controller, because it didn't get the value direct from the form, is there a pretty way to do this?
Routing was another problem, since it was trying to build routes based in the inherited models names. I overcome that by adding the other models in routes pointing to the same controller.
