SequelizeDatabaseError-缺少列-一對多關聯

Question

我沿着下面的教程以下這里

一切都取決於列出待辦事項中的待辦事項

向服務器發出獲取請求時，我收到以下錯誤報告：

{"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\";"}

我對本教程做了一些小的修改：

• 我使用ItemSet ，而不是ToDo
• 我使用Item ，而不是ToDoItem

理想情況下，我希望返回以下內容：

我認為問題是在ItemSet模型中定義的itemId 。

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

我認為您沒有在任何地方定義itemId
