Question

我想在Spree :: User中添加vendor?函数。所以我创建了 app / models / spree / user.rb

module Spree
  class User < Spree::Base

    include Spree::UserMethods

    def vendor?
      self.role_users.any? { |ru| ru.role.name == 'vendor' }
    end

  end
end

如果我启动rails console并测试，这是有效的： u = Spree::User.last; u.vendor? # => false

但是当我启动rails服务器并访问某个页面时，我收到此错误： Spree :: Admin :: OrdersController #index中的NoMethodError 未定义的方法`serialize_from_session＆＃39;对于＃

知道我该怎么做才能解决这个错误吗？根据堆栈跟踪，看起来我在某个地方错过了一个方法。

答案是打开Spree :: User类并添加您缺少的方法：

E.g：

配置/初始化/ spree_user.rb

 Spree::User.class_eval do

    def vendor?
      self.role_users.any? { |ru| ru.role.name == 'vendor' }
    end

end

如何从使用solidus gem的Rails应用程序扩展Spree :: User类
