Sequelize MySQL 模型扩展为 class findOrCreate 方法无法创建记录

Question

我的问题是，当下面的代码运行时，它会构建 MySQL 查询并运行它，但是，它会抛出此错误：ValidationError [SequelizeValidationError]: notNull Violation: Guilds.GuildPremium cannot be null。

但是，这些字段具有在模型中的超级初始化方法中定义的默认值。如果所述模型的实例不继承模型的属性，那么在模型中定义默认值的目的是什么？
另外，我是否必须在下面的代码片段中再次定义默认值？

感谢您的耐心和时间:)

运行:

的代码片段

const {NewGuild, created} = Guilds.findOrCreate({
    where: {
        DiscordGuildID: Guild.id
    }
})
    .then(() => {
        if(created) {
            console.log(`Guild ${Guild.id} added to Database!`);
        }
            else {
                NewGuild
                    .update({
                        GuildActive: true
                    })
                    .then(() => 
                        console.log(`Guild ${Guild.id} reactivated in Database!`)
                    );
            };
    });

模特公会：

module.exports = class Guilds extends Model {
static init(sequelize) {
    return super.init({
        GuildID: {
            type: DataTypes.INTEGER.UNSIGNED,
            autoIncrement: true,
            primaryKey: true,
            comment: "Guild Database ID"
        },
        DiscordGuildID: {
            type: DataTypes.INTEGER.UNSIGNED,
            allowNull: false
        },
        GuildPremium: {
            type: DataTypes.BOOLEAN,
            allowNull: false,
            default: false
        },
        DiscordGuildPrefix: {
            type: DataTypes.TEXT,
            allowNull: false,
            default: process.env.DefaultPrefix
        },
        GuildActive: {
            type: DataTypes.BOOLEAN,
            default: true,
            comment: "Bot active in Guild?"
        }
    }, {
        tableName: "Guilds",
        modelName: "Guilds",
        timestamps: true,
        sequelize
    });
};

Answer 1

默认值在您的代码中不起作用，因为您为此指定了错误的选项。用 defaultValue 替换 default 就可以了：

GuildPremium: {
            type: DataTypes.BOOLEAN,
            allowNull: false,
            defaultValue: false
        },
DiscordGuildPrefix: {
            type: DataTypes.TEXT,
            allowNull: false,
            defaultValue: process.env.DefaultPrefix
        },
        GuildActive: {
            type: DataTypes.BOOLEAN,
            defaultValue: true,
            comment: "Bot active in Guild?"
        }
