基于相关模型属性的环回滤波器 [英] Loopback Filter Based On Related Model Properties

问题描述

我希望能够根据相关模型的属性进行过滤.例如，我有一个带有建筑对象的Class对象.我想获取在特定建筑物中发生的课程的列表.

I want to be able to filter based on the properties of related models. For example, I have a Class object with a Building object. I want to get a list of classes that take place in a certain building.

此过滤器

{  
   "include":"building",
   "scope":{  
      "where":{  
         "name":"warehouse"
      }
   }
}

返回所有类，但仅包含名称为仓库"的建筑物.我想要的是将建筑物名称上的where子句应用于整个过滤器，以便仅在建筑物具有该名称的情况下才获得该类.

returns all classes, but only includes building if its name is "warehouse". What I want is for the where clause on building name to apply to the whole filter so that I only get the class if it's building has that name.

有什么办法可以做我想做的事吗?

Is there any way to do what I want?

谢谢！

推荐答案

您可以在代码中执行此操作，请参见

You can do this in code, see include with filters in the docs.

我不确定JSON，但我认为它应该更像这样:

I'm not sure about the JSON but I think it should look more like this:

  include: {
    relation: 'building',
    scope: {
      where: {name: 'warehouse'}
    }
  }
