在已标准化的vuex-orm数据库中插入数据

Question

假设我收到的数据已经正常化，或者至少是关系。如何将这些数据插入vuex-orm数据库？

示例JSON数据：

{
  "carmodel": [
    {
      "id": 1,
      "title": "M3",
      "manufacturer_id": 1
    },
    {
      "id": 2,
      "title": "a-class"
      "manufacturer_id": 2
    }
  ],
  "manufacturer": [
    {
      "id": 1,
      "title": "BMW"
    },
    {
      "id": 2,
      "title": "Mercedes"
    }
  ]
}

制造商模型和are模型插入如下：

Manufacturer.insert({ data: response.data.manufacturer })
CarModel.insert({ data: response.data.carmodel })

此示例模型将无法工作：

import { Model } from '@vuex-orm/core'
import Manufacturer from '@/models/Manufacturer'

export default class CarModel extends Model {
  static entity = 'carModels'

  static fields () {
    return {
      id: this.attr(null),
      title: this.string(''),
      manufacturer: this.hasOne(Manufacturer, 'manufacturer_id')
    }
  }
}

Answer 1

好吧，我想我明白了。与this.hasOne不同，我必须使用belongsTo并使用来自同一个模型的manufacturer_id：

import { Model } from '@vuex-orm/core'
import Manufacturer from '@/models/Manufacturer'

export default class CarModel extends Model {
  static entity = 'carModels'

  static fields () {
    return {
      id: this.attr(null),
      title: this.string(''),
      manufacturer_id: this.attr(null),
      manufacturer: this.belongsTo(Manufacturer, 'manufacturer_id')
    }
  }
}
