Instance Method Details

#all(graph = Zuck.graph, parent = nil) ⇒ Object

Automatique all getter.

Let's say you want to fetch all campaigns from facebook. This can happen in the context of an ad account. In this gem, that context is called a parent. This method would only be called on objects that inherit from Zuck::FbObject. It asks the parent for it's path (if it is given), and appends it's own list_path property that you have defined (see list_path)

If, however, you want to fetch all ad creatives, regardless of which ad group is their parent, you can omit the parent parameter. The creatives returned by Zuck::AdCreative.all will return nil when you call #ad_group on them, though, because facebook will not return this information. So if you can, try to fetch objects through their direct parent, e.g. my_ad_group.ad_creatives.

Parameters:

  • graph (Koala::Facebook::API) (defaults to: Zuck.graph) —

    A graph with access_token

  • parent (<FbObject] A parent object to scope) (defaults to: nil) —

    arent [<FbObject] A parent object to scope
