您好我正在尝试将我的用户模型与登录模型和Question_details模型相关联。但是,如果我使用Question_details关联,那么我正在调整eagerLodingError:用户与登录没有关联,但如果我正在评论它,那么它工作正常我该如何联想呢?
但如果我正在与
联系User Model
module.exports = (sequelize, DataTypes) => {
var Users = sequelize.define('users', {
name: {
type: DataTypes.STRING(100)
}
phone: {
type: DataTypes.BIGINT,
unique: true
}
}, { freezeTableName: true });
Users.associate = function(models) {
Users.hasOne(models.login, {
foreignKey: 'user_id',
as: 'loginDetails'
});
};
Users.associate = function(models) {
Users.hasMany(models.customer_query, {
foreignKey: 'user_id',
as: 'queryDetails'
});
};
return Users;
};
登录模型
module.exports = (sequelize, DataTypes) => {
var Login = sequelize.define('login', {
user_id: {
type: DataTypes.INTEGER
},
user_name: {
type: DataTypes.STRING(500),
isEmail: true
},
password: {
type: DataTypes.STRING(500)
},
role_id: {
type: DataTypes.INTEGER
}
}, {
underscored: true,
freezeTableName: true
});
Login.associate = function(models) {
Login.belongsTo(models.users, {
foreignKey: 'user_id',
onDelete: 'CASCADE'
});
};
Login.associate = function(models) {
Login.belongsTo(models.roles, {
foreignKey: 'role_id',
onDelete: 'CASCADE'
});
};
return Login;
};
questionDetails模型
module.exports = function(sequelize, DataTypes) {
var questionDetails = sequelize.define('question_details', {
query_id: {
type: DataTypes.INTEGER
},
ques_type_id: {
type: DataTypes.INTEGER
},
created_by: {
type: DataTypes.INTEGER
},
question: {
type: DataTypes.TEXT
},
}, { freezeTableName: true });
questionDetails.associate = function(models) {
questionDetails.belongsTo(models.users, {
foreignKey: 'created_by',
onDelete: 'CASCADE'
});
};
return questionDetails;
};

您只需要定义一次关联。当你第二次定义它时,你实际上会覆盖它。因此,对于User
模型,您应该实际执行...
Users.associate = function(models) {
Users.hasOne(models.login, {
foreignKey: 'user_id',
as: 'loginDetails'
});
Users.hasMany(models.customer_query, {
foreignKey: 'user_id',
as: 'queryDetails'
});
};
对您的登录模型执行类似操作,因为您还要覆盖那里的associate
函数。
