Rails 5, Undefined `for 'method for # <Devise on line devise_parameter_sanitizer.for

Question

I work with Rails 5

I added a new field username to the user model.

class Users::RegistrationsController < Devise::RegistrationsController before_action :configure_permitted_parameters protected def configure_permitted_parameters devise_parameter_sanitizer.for(:sign_up).push(:username) end end 

An error is displayed during registration: undefined `for 'method for # Did you mean? fork

Trace:

NoMethodError (undefined `for 'method for # you mean? Fork):

 app/controllers/users/registrations_controller.rb:7:in `configure_permitted_parameters' Rendering /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/diagnostics.html.erb within rescues/layout Rendering /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/_source.html.erb Rendered /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/_source.html.erb (5.0ms) Rendering /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/_trace.html.erb Rendered /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/_trace.html.erb (2.9ms) Rendering /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/_request_and_response.html.erb Rendered /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/_request_and_response.html.erb (1.2ms) Rendered /usr/local/rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.rc1/lib/action_dispatch/middleware/templates/rescues/diagnostics.html.erb within rescues/layout (118.1ms) 

Who can help? How to solve this problem?

Answer 1

According to the documentation:

Sanitaizer options API 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]) end end 

Answer 2

If you just change .for to .permit , it also works. 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

Answer 3

Do not forget devise_parameter_sanitizer.permit(:account_update, keys: [:username])

Answer 4

 class ApplicationController < ActionController::Base before_action :configure_permitted_paramters, if: :devise_controller? protected def configure_permitted_paramters devise_parameter_sanitizer.permit(:sign_up, keys: [:fullname]) devise_parameter_sanitizer.permit(:account_update, keys: [:fullname, :phone_number, :description, :email, :password]) end end 

Answer 5

Alternatively use Devise gem version 4.1:

 gem 'devise', '~> 4.1.0'
