Rails 4/Devise/MongoDB: “Unpermitted parameters” using custom properties and strong parameters

Question

Trying to add a nested custom attribute, Profile (a Mongoid document), to my devise User class. When the Devise registration form is submit

Answer 1

I had the exact same issue and overriding sign_up_params did work for me

def sign_up_params
   params.require(:user).permit(:email, :password, :password_confirmation, :other, :etc)
end

of course, the difference is in that mine are just scalar values, while you're trying to mass assign a relation... I guess that's where you should look for.

By the way, the documentations is still inexistint in this topic (too new), and code commnents suggest to override devise_parameter_sanitizer, which isn't necessary.
