Resetting user password when devise_for routes are in scope

Question

In my application all routes are scoped to a locale, that user has selected like this:

scope ":locale", locale: /#{SpreeI18n::Config.supported_locales.join('|')}/ do
  devise_for :users, skip: :omniauth_callbacks
  get '/', to: 'homepage#index', :as => :homepage
end

When I want to send reset password instructions like User.find(1).send_reset_password_instructions, there is a problem:

Devise::Mailer#reset_password_instructions: processed outbound mail in 4249.9ms
ActionView::Template::Error: No route matches {:action=>"edit", :controller=>"devise/passwords", :reset_password_token=>"-zyuNkscVkwFn2awdm27"} missing required keys: [:locale]

How can I pass locale so that I can send the reset token?

Answer 1

Let's create a custom controller for password:

1. Customize routes.rb

   scope ":locale", locale: /#{SpreeI18n::Config.supported_locales.join('|')}/ do
     devise_for :users, skip: :omniauth_callbacks, controllers: { passwords: 'my_passwords' }
     get '/', to: 'homepage#index', :as => :homepage
   end
   

2. my_passwords_controller.rb

   class MyPasswordsController < Devise::PasswordsController
     def create
       resource_params.merge!(locale: 'en') # use 'en' for eg
       super
     end
   end
   

Then send_reset_password_instructions function will take your customized resource_params when sending the email.
