`include ActiveModel::Model` with class name having more than two words

Question

It seems I am missing the magic of ruby on rails 4. I wanted to create an object which includes ActiveModel::Model but which class name contains two words.

Therefore I created app/models/registration_form.rb with the following code:

class RegistrationForm
    include ActiveModel::Model
    attr_accessor(:email)
    validates :email, presence: true
end

When the object is created within the controller by using RegistrationForm.new the following error occurs:

Could not find table 'registration_forms'

When I just delete the postfix Form and rename the file to app/models/registration.rb everthing works fine.

When the code from above is executed within rails console everything works fine, too.

The stacktrace of the error shows that ActiveRecord is called: https://gist.github.com/anonymous/273986937cd774b5953c

ActiveModel, I don't know why ActiveRecord is called. Which is the best way to debug this? — AlexN, Jan 04 '16 at 22:14
Does this model have a database table? If not, are you sure you don't just want to include parts of ActiveModel, e.g. ActiveModel::Validations? — Jordan Running, Jan 04 '16 at 22:27
Does your app contain another RegistrationForm class that does subclass from active record? — Frederick Cheung, Jan 04 '16 at 22:29

It looks like you are trying to initialise an ActiveRecord object in your parties controller. It may simply be a name collision. Do you have another file defining RegistrationForm as a regular ActiveRecord model?
