环回：如何订购相关模型？

Question

我正在尝试对相关模型的属性进行排序，但无法使其正常工作。

我正在加载一张交货时刻表，并想对postal_code进行排序，而postal_code是相关模型“ postalcode”的属性

这是我的交货时刻模型：

{
  "name": "delivery_moment",
  "plural": "delivery-moments",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true,
    "mysql": {
      "schema": "LOOPBACK",
      "table": "table_delivery_moment"
    }
  },
  "mixins": {
    "TimeStamp": {
      "createdAt": "created",
      "updatedAt": "updated",
      "required": false,
      "validateUpsert": true,
      "silenceWarnings": false
    }
  },
  "properties": {
    "created": {
      "type": "date",
      "required": false
    }
  },
  "validations": [],
  "relations": {
    "distributor": {
      "type": "belongsTo",
      "model": "distributor",
      "foreignKey": "distributor_id"
    },
    "delivery_times": {
      "type": "hasAndBelongsToMany",
      "model": "delivery_time",
      "as": "delivery_moment_id",
      "foreignKey": "delivery_time_id",
      "throughTable": "delivery_moment_delivery_time"
    },
    "postalcode": {
      "type": "belongsTo",
      "model": "postalcode",
      "foreignKey": "postal_code_id"
    }
  },
  "acls": [],
  "methods": {}
}

这是我的邮政编码模型：

{
  "name": "postalcode",
  "plural": "postalcodes",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true,
    "mysql": {
      "schema": "LOOPBACK",
      "table": "table_postalcode"
    }
  },
  "properties": {
    "postal_code": {
      "type": "number",
      "required": false,
      "dataType": "integer"
    },
    "catering_area": {
      "type": "boolean",
      "required": false
    },
    "created": {
      "type": "date",
      "required": false
    }
  },
  "validations": [],
  "relations": {
    "delivery_moments": {
      "type": "hasMany",
      "model": "delivery_moments",
      "foreignKey": "postal_code_id"
    },
    "depot": {
      "type": "belongsTo",
      "model": "depot",
      "foreignKey": "hub_id"
    },
    "current_routes": {
      "type": "hasAndBelongsToMany",
      "model": "current_route",
      "as": "postalCodeId",
      "foreignKey": "currentRouteId",
      "throughTable": "table_postalcode_currentroute"
    }
  },
  "acls": [],
  "methods": {}
}

这是我要执行的查询：

?filter[include][0]=postalcode&filter[include][1]=distributor&filter[include][2]=delivery_times&filter[order]=postalcode.postal_code ASC

我尝试了多种变化，例如：

filter[order][postalcode]=postal_code ASC

但不对结果进行排序。如何获得理想的结果？
