Sequelize数据库报错列名不存在

Question

问题是 findAll 产品 select 的列不存在 "PermissionId"

不明白为什么sequelize会生成这个专栏

错误是：

Unhandled rejection SequelizeDatabaseError: column "PermissionId" does not exist at Query.formatError (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/sequelize/lib/dialects/postgres/query.js:366:16) at /home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/sequelize/lib/dialects/postgres/query.js:72:18 at tryCatcher (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/util.js:16:23) at Promise._settlePromiseFromHandler (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/promise.js:547:31) at Promise._settlePromise (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/promise.js:604:18) at Promise._settlePromise0 (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/promise.js:649:10) at Promise._settlePromises (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/promise.js:725:18) at _drainQueueStep (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/async.js:93:12) at _drainQueue (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/async.js:86:9) at Async._drainQueues (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/async.js:102:5) at Immediate.Async.drainQueues [as _onImmediate] (/home/baptiste/IUT2/ProjetS3/code/M3301/node_modules/bluebird/js/release/async.js:15:14) at processImmediate (internal/timers.js:439:21)

迁移代码：

你可以这样试试：

module.exports = (sequelize, DataTypes) => {
    const Utilisateurs = sequelize.define('Utilisateur', {
        adresseMail: DataTypes.STRING,
        nomUtilisateur: DataTypes.STRING,
        dateDeNaissance: DataTypes.STRING,
        motDePasse: DataTypes.STRING,
        // idPermission: DataTypes.INTEGER **I belive you must remove this line!
    }, {});
    Utilisateurs.associate = function (models) {
        Utilisateurs.belongsTo(models.Permission, { foreignKey: 'idPermission'});
        Utilisateurs.hasMany(models.Licencie);
    };
    return Utilisateurs;
};

我尝试做的是为 table 指定 foreign_PK，sequelize 将默认尝试 PermissionId，但您的密钥是 idPermission。

请为我糟糕的英语道歉！

Answer 2

非常感谢 Carlos Filipe Braz！我找到了，所以我需要在 class Permission 和 Utilisateur 中添加 { foreignKey: 'idPermission'} 那就是工作


module.exports = (sequelize, DataTypes) => {
    const Permission = sequelize.define('Permission', {
        estRegatier: DataTypes.BOOLEAN,
        estJury: DataTypes.BOOLEAN,
        estOrganisateur: DataTypes.BOOLEAN
    }, {});
    Permission.associate = function (models) {
        Permission.hasMany(models.Utilisateur, { foreignKey: 'idPermission'});
    };
    return Permission;
};
/*Utilisateur*/
'use strict';
module.exports = (sequelize, DataTypes) => {
    const Utilisateurs = sequelize.define('Utilisateur', {
        adresseMail: DataTypes.STRING,
        nomUtilisateur: DataTypes.STRING,
        dateDeNaissance: DataTypes.STRING,
        motDePasse: DataTypes.STRING
        /*idPermission: DataTypes.INTEGER*/
    }, {});
    Utilisateurs.associate = function (models) {
        Utilisateurs.belongsTo(models.Permission, { foreignKey: 'idPermission'});
        Utilisateurs.hasMany(models.Licencie);
    };
    return Utilisateurs;
};
