plan id not being assigned in Devise form. Rails - ruby-on-rails

Question

I have a Rails app with 3 sign up button links on the home page.
Each has it's own plan assigned to it. Two of them go to a basic form while the third goes to a form with credit card details, handled by Stripe. The forms and Users are handled by Devise.
The plans seem to be setup correctly and are seen in the rails console however, when I go to sign up, to any of them, only the email address and password is captured, and NO plan_id is assigned.
I've noticed when previewing the form pages locally that the url at the top doesn't change to the specific form url, i.e /users/sign_up?plan=3 for example, but instead shows the form but stays on the homepage url? I'm confused because the server seems to recognise which link i'm clicking on and which plan needs to be assigned?? Please Help!!

Answer 1

To allow plan_id to be save you need to add it in devise signup parameters. You can do this by adding following into your application controller
before_filter :configure_permitted_parameters, if: :devise_controller?
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password_confirmation, :plan_id) }
end
