javascript - Sequelize : how to use `scope` inside `include` ?

Question

我想问一下是否可以在 include 选项中使用关联模型的范围？

在我的例子中，有两个模型，User 和 Code:

const ACTIVE_FIELDS = ['fullname', 'idCard']
const User = sequelize.define('User', {
  uid: DataTypes.STRING,
  fullname: DataTypes.TEXT,
  idCard: DataTypes.STRING,
  province: DataTypes.STRING,
}, {
  scopes: {
    activated: {
      where: ACTIVE_FIELDS.reduce((condition, field) => {
        condition[field] = {[sequelize.Op.ne]: null}
        return condition
      }, {}),
    },
    inProvinces: (provinces) => ({
      where: {
        province: {
          [sequelize.Op.in]: provinces,
        },
      },
    }),
  },
})

const Code = sequelize.define('Code', {
  id: {
    type: DataTypes.STRING,
    primaryKey: true,
  },
  uid: DataTypes.STRING,
}, {});

Code 通过uid

属于 User

Code.belongsTo(User, {
  foreignKey: 'uid',
  targetKey: 'uid',
  as: 'user',
})

我想选择一个随机的 Code 激活用户和特定省份。有什么方法可以重用 activated 和 inProvinces 范围，所以它看起来像:

const randomCode = (provinces) =>
  Code.findOne({
    include: [{
      model: User,
      as: 'user',
      scopes: ['activated', {method: ['inProvinces', provinces]}],
      attributes: [],
      required: true,
    }],
    order: sequelize.random(),
  })

Answer 1

尝试将您的范围附加到实际模型....它对我有用。

Code.findOne({
  include: [{
    model: User.unscoped() 
  }],
})

@eee 更新 - 更清楚:

Code.findOne({
  include: [{
    model: User.scope('activated', {method: ['inProvinces', provinces]}) 
  }],
})

我认为这应该可行...
