Rails 5, Undefined method `for' for #<Devise on line devise_parameter_sanitizer.for
According to the documentation:
The Parameter Sanitaizer API has changed for Devise 4
class ApplicationController < ActionController::Base before_action :configure_permitted_parameters, if: :devise_controller? protected def configure_permitted_parameters devise_parameter_sanitizer.permit(:sign_up, keys: [:username]) endend
If you just change the .for to .permit it works as well. For example:
devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit({ roles: [] }, :email, :password, :password_confirmation, :username) }It works in both Rails 4.2.x and Rails 5.0.x
Don't forget devise_parameter_sanitizer.permit(:account_update, keys: [:username])
