sequelizedAtabaseError:运算符不存在UUID =整数



我正在尝试使用基于uuid的两个表(我也有ID(加入,这些表有一些困难的关系...

当我运行查询时,我会收到错误。

第一个表被称为用户,他的UUID称为 impristry_uuid 。第二个表受益人,但此表有两个UUID, uuid_beneficiary uuid_benefactor

为什么?因为第一个表有列 user_type_id ,因此我们可以知道它是否是用户受益人恩人。第二个表是知道哪些用户是相关的。

模型用户

const User = sequelize.define('users', {
registry_uuid: {
    type: Sequelize.UUIDV4,
    defaultValue: Sequelize.UUIDV4,
    allowNull: false
    },
user_type_id: {
    type: Sequelize.INTEGER,
    defaultValue: 1,
    allowNull: false
    }
}

模型受益人

const Beneficiary = sequelize.define('beneficiaries', {
uuid_benefactor: {
    type: Sequelize.UUIDV4,
    defaultValue: Sequelize.UUIDV4,
    allowNull: false
    },
uuid_beneficiary: {
    type: Sequelize.STRING,
    defaultValue: Sequelize.UUIDV4,
    allowNull: false
    },
created_at: {
    type: Sequelize.DATE,
    defaultValue: Sequelize.NOW
    },
disassociation_date: {
    type: Sequelize.DATE,
    defaultValue: null
    }
}

查询

async function getBenefactorOfBeneficiary (benefactorUuid, arrayAttributes) {
arrayAttributes = arrayAttributes || ['registry_uuid', 'name', 'last_name', 'picture']
return UserModel.findOne({
  where: {
    registry_uuid: {
      [Op.eq]: benefactorUuid
    }
  },
  include: [{
    model: BeneficiaryModel,
  }],
  attributes: arrayAttributes,
  raw: true
})
}

关系

UserModel.hasMany(beneficiaryModel, {foreignKey: 'uuid_benefactor'})
beneficiaryModel.belongsTo(UserModel, {foreignKey: 'registry_uuid'})

我期望输出:

示例:

{
  "name": "string",
  "lastName": "string",
  "picture": "string",
  "created_at" "string"
}

显然我在控制器中修改了响应

您应该首先检查包含的模型及其ID类型。他们必须具有相同的类型。除此之外,假设我们有用户和榜样。每个用户只能具有一个角色,并且几个用户可以使用一个角色。在这种情况下,如果您写错误的关联,您将遇到此错误。

错误版本:

// Under the user model associations 
user.hasOne(models.role, { foreignKey: "roleId" });
// this will try to compare your userId with roleId of Role table
// Under the Role model associations 
role.hasMany(models.user, { foreignKey: "roleId" });

正确的版本应该像:

// Under the user model associations 
user.hasOne(models.role, { foreignKey: "roleId" });
// this will try to compare your roleId from User model with roleId of Role table
// Under the Role model associations 
role.hasMany(models.user, { foreignKey: "roleId" });
