Question

我有一个名为subscription的模型，它与另一个模型category有hasMany关系。

你应该做的是:

• 在common/models/subscription.json中:

    {
     ...
      "relations": {
          "categories": {
            "type": "hasMany",
            "model": "Category",
            "foreignKey": ""
          }
      }
   }
  

• 在common/models/category.json中:

    {
     ...
      "relations": {
          "subscription": {
            "type": "belongsTo",
            "model": "Subscription",
            "foreignKey": ""
          }
      }
   }
  

在 REST 中(即来自 API Explorer):

GET /Subscriptions?filter[include]=categories

在代码中(即在 remote hook 中:common/models/subscription.js):

Subscription.find({include: 'categories'}, function (err, subscriptions) {
    console.log(subscriptions);
    //...
});
