Rails Devise Invitable无法正常工作未初始化的常量用户

Question

邀请控制器

class InvitationsController < Devise::InvitationsController

 def new
 end

 def create
 end

end

routes.rb

  devise_for :users, :controllers => { :invitations => 'users/invitations' }

应用程序控制器

class ApplicationController < ActionController::Base
 # Prevent CSRF attacks by raising an exception.
 # For APIs, you may want to use :null_session instead.
 protect_from_forgery with: :exception
 before_filter :configure_permitted_parameters, if: :devise_controller?

 protected

 def configure_permitted_parameters
 # Only add some parameters
 devise_parameter_sanitizer.for(:accept_invitation).concat [:email]
 # Override accepted parameters
 devise_parameter_sanitizer.for(:accept_invitation) do |u|
  u.permit(:email, :password, :password_confirmation,
         :invitation_token)
 end
end

users_controller

def new
 @user = User.new(:invitation_token => params[:invitation_token])
 @user.email = @user.invitation.recipient_email if @user.invitation
end

当我转到“/users/invitation/new”时，我收到错误“未初始化的常量用户”。我错过了什么？谢谢

试试

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

相反，如果您覆盖方法，您可能需要调用父级，使用 super 像这样：

```

class InvitationsController < Devise::InvitationsController

   def new
     super
   end

end

```
