Strong parameter override for DeviseTokenAuth controller

问题

I am using devise-token-auth gem on Rails 4.2, and I've added a field nickname to the User model. I am trying to implement this via an override of the gem controller

class Users::RegistrationsController < DeviseTokenAuth::RegistrationsController

  before_filter :configure_permitted_parameters

  def update
    #this line never shows in the logs
    Rails.logger.info "I never get to run!!"
    super
  end

  protected

  # my new custom field is :nickname
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:name, :nickname,
        :email, :password, :password_confirmation)
    end
    devise_parameter_sanitizer.for(:account_update) do |u|
      u.permit(:name,
        :email, :password, :password_confirmation, :nickname)
    end
  end
end

The routes are configured like this:

  Rails.application.routes.draw do
    namespace :api, constraints: { format: 'json' } do
        mount_devise_token_auth_for 'User', at: 'auth', controllers: {
          registrations:  'users/registrations'
        }
    end
  end

and they seem about right:

PATCH  /api/auth(.:format)                    users/registrations#update {:format=>"json"}
PUT    /api/auth(.:format)                    users/registrations#update {:format=>"json"}

Then I try to call the update from curl

curl -X PUT --dump-header headers_update -H "Access-Token: 2FHhLQFtIgDfSqsTaaCH_g" -H "Uid: sample5@example.com" -H "Client: -RUtwnCfgqvqwDjYPtajQA" -H "Token-Type: Bearer" -H "Expiry: 1447713314" http://api.local.dev:3000/api/auth -d "{ \"nickname\":\"somestuff\"}"

But the update call never gets to runs. This is what shows the server after the request:

and the json reply to curl is:

{"status":"error","errors":["Please submit proper account update data in request"]}

For reference, here is my Gemfile

source 'https://rubygems.org'


gem 'rails', '4.2.1'

gem 'rails-api'

gem 'pg'
gem 'activerecord-postgis-adapter'
gem 'rgeo'

It worked for me.

1. extract RegistrationsController from devise-token-auth gem
2. create app/controllers/users/registrations_controller.rb:

.

class Users::RegistrationsController < DeviseTokenAuth::RegistrationsController

end

and paste the content from p.1

3. add to the end of controller:

.

def sign_up_params              
   params.require(:registration).permit(:name, :nick, :email, :password, :password_confirmation)

end

4. configure routes as you did

Update:

This change to Step 3 works with devise_token_auth v0.1.39: def sign_up_params permit(:name, :email, :password, :password_confirmation) end

You can override devise registrations controller by doing this:

class RegistrationsController < Devise::RegistrationsController

  private

  def sign_up_params
    params.require(:user).permit(:name, :nickname, :email, :password, :password_confirmation)
  end

  def account_update_params
    params.require(:user).permit(:name, :nickname, :email, :password, :password_confirmation, :current_password)
  end
end

Then on your routes:

devise_for :users, :controllers => { registrations: 'registrations' }
