Hi

Models don’t belong to controllers. They are two separate classes
that, to make things more practical, often have a similar name.

You could just as easily have a Post model and a BlogController and
Rails wouldn’t know the difference.

If you’re trying to guess the name of model from the controller that
deals with creating and maintaining its records you could try:

def get_model
self.class.to_s.gsub(“Controller”,“”).singularize.constantize
end

This would return Comment if called in the CommentsController.

Hope that helps?

In Ruby there is always “something called self”. It’s really worth
understanding what it is at any given time.

on Rails this year. The video is available:

I am not sure what you are asking here, could you explain in a little
more detail what you are trying to do? With an example if possible.
