环回4 hasMany包含过滤器错误500 [英] loopback 4 hasMany include filter Error 500

问题描述

我正在按照回授列表dodo-list进行一些回送4的练习 https://loopback.io/doc/zh/lb4/todo- list-tutorial.html

i am doing some practice with loopback 4, following the tutorial todo-list https://loopback.io/doc/en/lb4/todo-list-tutorial.html

我正在尝试查询凝胶待办事项列表和相关待办事项的数据

i am trying to query data to gel todo-lists and related todos

GET http://127.0.0.1:3000/todo-lists ?filter [include] = todos

我得到一个错误500:未为模型TodoList定义关系"todos"

i get an error 500 : relations "todos" not defined for the model TodoList

路由GET http://localhost:3000/todo-lists/1/todos 正常工作，但我想检索列表和相关的待办事项.

The route GET http://localhost:3000/todo-lists/1/todos works properly, but i'd like to retrieve lists and related todos.

我阅读了许多帖子和文档，但是我不明白哪里出了问题.

I read many posts and the documentation but i do not understand what is wrong.

谢谢

LoopBack 4在查询数据库时尚不支持包含相关模型.您可以加入以下GitHub问题中的讨论:

LoopBack 4 does not yet support inclusion of related models when querying the database. You can join the discussion in the following GitHub issues:

• 包含相关模型#1352
• 在"GET/mymodels"结果#1889 中包含相关模型

• Inclusion of related models #1352
• Include related models in "GET /mymodels" results #1889
