Node.js SequelizeDatabaseError-缺少列-一对多关联

我遵循下面的教程

一切正常

向服务器发出get请求时，我收到以下错误报告：

{"name":"SequelizeDatabaseError","parent":{"name":"error","length":104,"severity":"ERROR","code":"42703","position":"440","file":"parse_relation.c","line":"2743","routine":"errorMissingColumn","sql":"SELECT \"ItemSet\".\"id\", \"ItemSet\".\"title\", \"ItemSet\".\"createdAt\", \"ItemSet\".\"updatedAt\", \"items\".\"id\" AS \"items.id\", \"items\".\"content\" AS \"items.content\", \"items\".\"complete\" AS \"items.complete\", \"items\".\"createdAt\" AS \"items.createdAt\", \"items\".\"updatedAt\" AS \"items.updatedAt\", \"items\".\"itemSetId\" AS \"items.itemSetId\", \"items\".\"itemId\" AS \"items.itemId\" FROM \"ItemSets\" AS \"ItemSet\" LEFT OUTER JOIN \"Items\" AS \"items\" ON \"ItemSet\".\"id\" = \"items\".\"itemId\";"},"original":{"name":"error","length":104,"severity":"ERROR","code":"42703","position":"440","file":"parse_relation.c","line":"2743","routine":"errorMissingColumn","sql":"SELECT \"ItemSet\".\"id\", \"ItemSet\".\"title\", \"ItemSet\".\"createdAt\", \"ItemSet\".\"updatedAt\", \"items\".\"id\" AS \"items.id\", \"items\".\"content\" AS \"items.content\", \"items\".\"complete\" AS \"items.complete\", \"items\".\"createdAt\" AS \"items.createdAt\", \"items\".\"updatedAt\" AS \"items.updatedAt\", \"items\".\"itemSetId\" AS \"items.itemSetId\", \"items\".\"itemId\" AS \"items.itemId\" FROM \"ItemSets\" AS \"ItemSet\" LEFT OUTER JOIN \"Items\" AS \"items\" ON \"ItemSet\".\"id\" = \"items\".\"itemId\";"},"sql":"SELECT \"ItemSet\".\"id\", \"ItemSet\".\"title\", \"ItemSet\".\"createdAt\", \"ItemSet\".\"updatedAt\", \"items\".\"id\" AS \"items.id\", \"items\".\"content\" AS \"items.content\", \"items\".\"complete\" AS \"items.complete\", \"items\".\"createdAt\" AS \"items.createdAt\", \"items\".\"updatedAt\" AS \"items.updatedAt\", \"items\".\"itemSetId\" AS \"items.itemSetId\", \"items\".\"itemId\" AS \"items.itemId\" FROM \"ItemSets\" AS \"ItemSet\" LEFT OUTER JOIN \"Items\" AS \"items\" ON \"ItemSet\".\"id\" = \"items\".\"itemId\";"}

我对教程做了一些小修改：

• 我使用

  ItemSet

  ，而不是

  ToDo

• 我使用

  Item

  ，而不是

  ToDoItem

理想情况下，我想要返回的东西如下所示：

---

我的代码在这里可用：

我认为问题在于模型中定义的

itemId

---

我认为你没有在任何地方定义

itemSetId

太棒了谢谢，我在教程中丢失了一个

itemSetId

的大写字母。（然后我感到沮丧，发明了另一个变量名，使情况复杂化

itemId

，显然

setid

）。谢谢你的帮助，你甚至让我看了文档。Github回购协议已经更新。

ItemSet.associate = function(models) {
    ItemSet.hasMany(models.Item, {
      foreignKey: 'itemId',
      as: 'items',
    });
  };
