Open Graph Beta：聚合的“分组依据”场地
Open Graph beta 的文档说：
分组依据 - 仅当显示聚合时选项才可用 对象。此选项允许聚合按属性分组 物体。例如，您可以按电影对象的类型进行分组，以显示 您观看某种类型的电影的次数。
你如何选择这个？
我有 Egg 对象，它有一个 Collection 属性，并希望基于该属性进行聚合。
例如，一个聚合故事将包含 Collection 设置为“复活节”的 Egg 对象，另一个聚合故事将包含 Collection< 的 Egg 对象。 /code> 设置为“圣诞节”。
Group By 似乎总是默认选择我为要显示的数据 选择的对象类型，但我没有看到手动设置此选项的选项。我也没有找到将聚合标题设置为组名称的方法。
The documentation for the Open Graph beta says:
Group by - Option is only available if your Aggregation is displaying
Objects. This option allows the aggregation to group by a property of
the object. For example, you can group by Movie object's type, to show
how many times you've watched a certain type of movie.
How do you select this?
I have Egg objects with that have a Collection property and want to aggregate based on that.
For example, one aggregate story would include Egg objects with Collection set to "Easter" and another would include Egg objects with Collection set to "Christmas".
Group By always seems to default select the object type I choose for Data to Display and I don't see an option to manually set this. Nor do I see a way to set the Aggregation Title to be the name of the group.

您不能按字符串分组，只能按对象分组。尝试创建一个名为
Collection的对象类型，并为每个集合创建 url。然后Collection将显示在Data to Display中，您可以按它进行分组。You can't group by a String, only an Object. Try making an Object Type called
Collectionand make urls for each collection. ThenCollectionwill show up inData to Displayand you can group by it.
