|

This class acts a proxy for a Graphene Type, so it can be mounted
|
|
dynamically as Field, InputField or Argument.
|
|
|
|
Instead of writing:
|
|
|
|
.. code:: python
|
|
|
|
from graphene import ObjectType, Field, String
|
|
|
|
class MyObjectType(ObjectType):
|
|
my_field = Field(String, description='Description here')
|
|
|
|
It lets you write:
|
|
|
|
.. code:: python
|
|
|
|
from graphene import ObjectType, String
|
|
|
|
class MyObjectType(ObjectType):
|
|
my_field = String(description='Description here')
|
|
|
|
It is not used directly, but is inherited by other types and streamlines their use in
|
|
different context:
|
|
|
|
- Object Type
|
|
- Scalar Type
|
|
- Enum
|
|
- Interface
|
|
- Union
|
|
|
|
An unmounted type will accept arguments based upon its context (ObjectType, Field or
|
|
InputObjectType) and pass it on to the appropriate MountedType (Field, Argument or InputField).
|
|
|
|
See each Mounted type reference for more information about valid parameters.
