Removing a Devise user model possible?

Question

Is there a way to remove a previously generated devise model? I had generated 2 models with devise: user and student . Now I'm having trouble with the 2 different login pages and their routes, so I decided to switch to a single table inheritance solution (following a suggestion here ).

So I want to keep the devise model user and generate 2 models with rails g model ... that inherit from the user model: teacher and student .

But since I already have a devise model named student I was wondering if I could somehow delete the existing model and corresponding db table, or if it was enough to simply delete these 2 lines from the model:

# app/assets/models/student.rb
devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

Answer 1

I don't think devise offers a generator that would bring your model back to a previous version (similar to rails destroy migration ... ). Apart from removing the devise method call from your model, you would need to get rid of the table itself (in a migration) and all the generated templates and controllers referring to the Student model, just to keep things clean.
