Ruby on rails 在我的RubyonRails/GraphQL项目中，是什么导致了这个未定义的方法错误
我第一次在GraphQL上做一个项目，遇到了一个我不知道的小问题。我有一个商业模式，一个用户模式和一个行业模式。该业务模型属于其他两种模型。脚手架视图操作按预期运行，但当我对业务运行图形查询并包含其他两个模型时，它会出错 用户未定义的“映射”方法：0x00007fadeb73f140>\n您的意思是什么？ 水龙头 以下是我在query_type.rb中的定义：Ruby on rails 在我的RubyonRails/GraphQL项目中，是什么导致了这个未定义的方法错误,ruby-on-rails,ruby,graphql,Ruby On Rails,Ruby,Graphql,我第一次在GraphQL上做一个项目，遇到了一个我不知道的小问题。我有一个商业模式，一个用户模式和一个行业模式。该业务模型属于其他两种模型。脚手架视图操作按预期运行，但当我对业务运行图形查询并包含其他两个模型时，它会出错 用户未定义的“映射”方法：0x00007fadeb73f140>\n您的意思是什么？ 水龙头 以下是我在query_type.rb中的定义： # get all businesses field :businesses, [Types::BusinessType], n

我可以通过更改business_type.rb中的以下行来解决此问题：
field :user, type: [Types::UserType], null: false
更新：第一个示例只适用于对象列表，第二个示例适用于单个对象您得到的错误的整体堆栈跟踪是什么？@SebastianPalma谢谢-刚刚发布在上面您是否有用户类型、用户模型以及用户模型上是否有电子邮件属性？@trueinViso是的，我有，我可以在图中毫无疑问地查询它，包括我为它定义的关系。但是，当我包含业务类型关系时，它会给我相同的错误，但是在业务对象上。但奇怪的是，如果我查询Industry对象并包含业务关系，它不会出错
field :user, type: [Types::UserType], null: false
field :user, Types::UserType, null: false
