Settings
========
Graphene-Django can be customised using settings. This page explains each setting and their defaults.
Usage
-----
Add settings to your Django project by creating a Dictonary with name ``GRAPHENE`` in the project's ``settings.py``:
.. code:: python
GRAPHENE = {
...
}
``SCHEMA``
----------
The location of the top-level ``Schema`` class.
Default: ``None``
.. code:: python
GRAPHENE = {
'SCHEMA': 'path.to.schema.schema',
}
``SCHEMA_OUTPUT``
-----------------
The name of the file where the GraphQL schema output will go.
Default: ``schema.json``
.. code:: python
GRAPHENE = {
'SCHEMA_OUTPUT': 'schema.json',
}
``SCHEMA_INDENT``
-----------------
The indentation level of the schema output.
Default: ``2``
.. code:: python
GRAPHENE = {
'SCHEMA_INDENT': 2,
}
``MIDDLEWARE``
--------------
A tuple of middleware that will be executed for each GraphQL query.
See the `middleware documentation <https://docs.graphene-python.org/en/latest/execution/middleware/>`__ for more information.
Default: ``()``
.. code:: python
GRAPHENE = {
'MIDDLEWARE': (
'path.to.my.middleware.class',
),
}
``RELAY_CONNECTION_ENFORCE_FIRST_OR_LAST``
------------------------------------------
Enforces relay queries to have the ``first`` or ``last`` argument.
Default: ``False``
.. code:: python
GRAPHENE = {
'RELAY_CONNECTION_ENFORCE_FIRST_OR_LAST': False,
}
``RELAY_CONNECTION_MAX_LIMIT``
------------------------------
The maximum size of objects that can be requested through a relay connection.
Default: ``100``
.. code:: python
GRAPHENE = {
'RELAY_CONNECTION_MAX_LIMIT': 100,
}
``CAMELCASE_ERRORS``
------------------------------------
When set to ``True`` field names in the ``errors`` object will be camel case.
By default they will be snake case.
Default: ``False``
.. code:: python
GRAPHENE = {
'CAMELCASE_ERRORS': False,
}
# result = schema.execute(...)
print(result.errors)
# [
# {
# 'field': 'test_field',
# 'messages': ['This field is required.'],
# }
# ]
.. code:: python
GRAPHENE = {
'CAMELCASE_ERRORS': True,
}
# result = schema.execute(...)
print(result.errors)
# [
# {
# 'field': 'testField',
# 'messages': ['This field is required.'],
# }
# ]
``DJANGO_CHOICE_FIELD_ENUM_V3_NAMING``
--------------------------------------
Set to ``True`` to use the new naming format for the auto generated Enum types from Django choice fields. The new format looks like this: ``{app_label}{object_name}{field_name}Choices``
Default: ``False``
``DJANGO_CHOICE_FIELD_ENUM_CUSTOM_NAME``
--------------------------------------
Define the path of a function that takes the Django choice field and returns a string to completely customise the naming for the Enum type.
If set to a function then the ``DJANGO_CHOICE_FIELD_ENUM_V3_NAMING`` setting is ignored.
Default: ``None``
.. code:: python
# myapp.utils
def enum_naming(field):
if isinstance(field.model, User):
return f"CustomUserEnum{field.name.title()}"
return f"CustomEnum{field.name.title()}"
GRAPHENE = {
'DJANGO_CHOICE_FIELD_ENUM_CUSTOM_NAME': "myapp.utils.enum_naming"
}
