【问题描述】：

我正在尝试为我的 dcauser 表制作模型。我被卡住了，因为它返回错误“属性无法识别的数据类型”。现在我不知道我是否在数据库中搞砸了，或者我的数据库无法正常工作，或者我是否在下面的代码中搞砸了。我遵循了一些指南，但我总是遇到上面提到的同一个问题。

var Sequelize = require('sequelize');
var sequelize = new Sequelize('postgres://postgres:xpwdx@localhost:xportx/xdbx');


const UserSchema = sequelize.define(
    'dcauser',
    {
        userid: {
            type: Sequelize.Integer,
            allowNull: false,
        }
    }
);


module.exports = UserSchema;

我收到以下错误：

C:\Users\luka\source\repos\dcaBotManager\node_modules\sequelize\lib\model.js:1005
        throw new Error(`Unrecognized datatype for attribute "${this.name}.${name}"`);
        ^

Error: Unrecognized datatype for attribute "dcauser.userid"

标签： node.js postgresql sequelize.js

【解决方案1】：

integer 关键字必须大写

{
    userid: {
        type: Sequelize.INTEGER,
        allowNull: false,
    }
}

【讨论】：

谢谢。这解决了我的问题！:)

【解决方案2】：

INTEGER 必须大写。见

https://sequelize.org/v5/manual/data-types.html

虽然您应该开始改用 DataTypes.INTEGER。

谢谢。它解决了我的问题:)。
