allow set_locale with strong_parameters gem & devise

Question

I'm using strong parameters gem on small project with devise

I have added User.rb a locale column. This is my controllers/users/registrations_controller.rb file:

class Users::RegistrationsController < Devise::RegistrationsController
  def resource_params
    params.require(:user).permit(:username, :email, :password, :password_confirmation, :locale)
  end
  private :resource_params
  def create
   #add params[:locale] to resource.locale here
   super
  end
end

These are the parameters received from form:

Parameters: {"authenticity_token"=>"ZyrtToHcwsX3zl2ive93cpYaom6HNGA/jnYcSg7pQUQ=", "user"=>{"username"=>"[email protected]", "email"=>"[email protected]", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Create account", "locale"=>"es"}

I would like add to user :locale column the parameter params[:locale]

How can I do it?

Thanks!

I have fixed the problem overriding the create method from this doc:

https://github.com/plataformatec/devise/blob/master/app/controllers/devise/registrations_controller.rb.

If you want add specify column or field locale on your model user with strong parameters gem, you can add to controllers/users/registrations_controller.rb the next:

class Users::RegistrationsController < Devise::RegistrationsController

  def create
    build_resource
    resource.locale = set_locale #set_locale or where you have stored your own locale
    if resource.save
      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_navigational_format?
        sign_up(resource_name, resource)
        respond_with resource, :location => after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
        expire_session_data_after_sign_in!
        respond_with resource, :location => after_inactive_sign_up_path_for(resource)
      end
    else
      clean_up_passwords resource
      respond_with resource
    end
  end

  def resource_params
    params.require(:user).permit(:username, :email, :password, :password_confirmation, :locale)
  end

  private :resource_params
end
