Rails: How to get the model class name based on the controller class name?

Question

class HouseBuyersController < ...
  def my_method
    # How could I get here the relevant model name, i.e. \"HouseBuyer\" ?
  end
end

Answer 1

If your controller and model are in the same namespace, then what you want is

controller_path.classify

controller_path gives you the namespace; controller_name doesn't.

For example, if your controller is

Admin::RolesController

then:

controller_path.classify # "Admin::Role" # CORRECT
controller_name.classify # "Role"        # INCORRECT
