Added a detail to Users, but value doesn't get picked up - ruby-on-rails

Question

I added an extra field in devise when a user signs up: "barge_name", when i go to the sign up page I enter a barge_name, email address and password this all works.
But when i try rails c, User.first is says barge_name is nil, I don't know why the value doesn't get picked up when signing up? Can someone help me with this?
#<User id: 1, email: "barcelona#gmail.com", created_at: "2019-10-31 17:43:21", updated_at: "2019-10-31 17:43:21", barge_name: nil>]

Unpermitted parameter: :barge_name

Answer 1

You have to add the new param like this.
application_controller.rb
before_action :configure_permitted_parameters, if: :devise_controller?
...
protected
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up, keys: [:barge_name])
devise_parameter_sanitizer.permit(:account_update, keys: [:barge_name])
end
Take notice of the two lines, one is for sign_up and one is for account_update, so new and edit actions basically.
