我正在创建一个应用程序(用户有很多组),现有用户可以在其中发送邀请人加入群组的邀请.如果sign_up url有一个邀请令牌,我需要覆盖create的默认设计控制器操作.

的routes.rb

devise_for :users do 
  match '/users/sign_out',:to => 'devise/sessions#destroy'
  match '/users/sign_up/:invitation_token',:to => 'registrations#create'

registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
#after_filter :add_user_to_group

def new
    super
end

def create
  if !params[:invitation_token].nil?
    token = params[:invitation_token]
    @invitation = Invitation.where "token" => token 
      if !@invitation.nil?
            build_resource
            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
    else
      flash[:notice] = "Invalid Token. Cannot signup with this Link." 
    end
  else
    super
  end
end

def after_sign_up_path_for(resource_or_scope)
  @user = current_user
  raise @user.inspect
  @invitation = Invitation.where "recipient_email" => @user.email
  if !@invitation.nil?
    @user.update_attribute(:invitation_id,@invitation.id)
    @user_group = UserGroup.new
    @user_group.user_id = @user.id
    @userGroup.group_id = @invitation.group_id
    @userGroup.save!  
  end
  after_sign_in_path_for(resource)
end

结束

日志

Started GET "/users/sign_up/83003a4fab004ef4c1934c15f7215e8dc6a57718" for 127.0.0.1 at 2012-12-11 14:53:18
Processing by RegistrationsController#create as HTML
  Parameters: {"invitation_token"=>"83003a4fab004ef4c1934c15f7215e8dc6a57718"}
  SQL (0.1ms)  BEGIN
  User Exists (1.0ms)  SELECT 1 AS one FROM `users` WHERE `users`.`name` IS NULL LIMIT 1
  User Exists (0.1ms)  SELECT 1 AS one FROM `users` WHERE `users`.`email` = '' LIMIT 1
   (0.1ms)  ROLLBACK

这会将我重定向到sign_up路径,但会在页面加载时执行验证.

Email can't be blank
Password can't be blank
Name can't be blank

在sign_up之后记录之前呈现的页面

   (127.8ms)  COMMIT

解决方法

我不得不做类似的事情.我最后添加了将令牌添加到用户模型并使用单独的控制器操作来接受邀请的代码：

user.rb

after_create :accept_invitation,if: :token

private
  def accept_invitation
    # Or whatever you need to add the invitation token.
    permission = Permission.find_by_token(token)
    if permission
      permission.update_attributes!(user_id: id,accepted: true) 
      UserMailer.admin_accepted_invitation_email(permission).deliver
    end
  end

registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController
  layout "home"

  def accept_invitation
  @invitation = Permission.find_by_token!(params[:token])
  @user = User.new(token: @invitation.token)
end
end
