Question

我对sequelize陌生，我试图通过关联表进行请求

我有一个名为ArrayBuffer

的模型

Experience

一秒钟叫做module.exports = function (sequelize, DataTypes) { const Experience = sequelize.define('experience', { internalId: { type: DataTypes.BIGINT, unique: true, allowNull: false, }, label: { type: DataTypes.STRING, unique: false, allowNull: false, }, picture: { type: DataTypes.TEXT, unique: false, allowNull: true, }, type: { type: DataTypes.STRING, validate: { isIn: { args: [[ 'generic', 'specific', ]], msg: 'Must be a valid type', }, }, unique: false, allowNull: true, }, author: { type: DataTypes.STRING, unique: false, allowNull: true, defaultValue: 'import', }, isActive: { type: DataTypes.BOOLEAN, defaultValue: true, }, }); Experience.associate = (models) => { Experience.belongsToMany(models.Tag, { as: 'Tags', through: models.ExperienceTag, }); }; return Experience; };

Tags

关联表名称为module.exports = function (sequelize, DataTypes) { const Tag = sequelize.define('tag', { internalId: { type: DataTypes.STRING, unique: true, allowNull: false, }, name: { type: DataTypes.STRING, unique: false, allowNull: false, }, author: { type: DataTypes.STRING, unique: false, allowNull: true, defaultValue: 'import', }, isActive: { type: DataTypes.BOOLEAN, defaultValue: true, }, }); Tag.associate = (models) => { Tag.belongsToMany(models.Experience, { as: 'Experiences', through: models.ExperienceTag, }); }; return Tag; }; 我想让所有拥有ExperienceTags的{{1}}

这是我的要求：

Experience

但是当我执行它时，会出现类似以下错误：

tagId = 44

Answer 1

我认为您需要在包含中添加foreach($jsonObjs as $obj) { echo '<tr>'; foreach($obj as $key => $value){ echo '<td>'.$value.'</td>'; } echo '</tr>'; }，因为您已经定义了与别名的关联

更改此

as: 'Experiences'

使用

Experience.findAll({
    include: [{
        model: ExperienceTag,
        where: { tagId: 44 },
    }],
})

Answer 2

我认为您希望添加Tag而不是ExperienceTag，以下示例可能会为您提供帮助

Experience.findAll({
        include: [{
            model: Tag, //model name which you want to include
            as: 'Tags', // you have to pass alias as you used while defining
            where: { tagId: 44 },
        }],
    })
