Module faunadb.query

This module contains functions that generate query objects, suitable to be passed into :any:FaunaClient.query.

In addition to these functions, queries may contain:

• None
• Numbers (1, 2.5)
• Strings ("foo")
• Lists ([1, "foo"])
• Dicts ({"foo": "bar"})
• A :any:Ref, :any:SetRef, :any:FaunaTime, or :class:datetime.date.

For example: select("a", {"a": Ref("123", Ref("widgets", Native.CLASSES))}).
