Camel case JSON support for Django REST framework.
At the command line::
$ pip install djangorestframework-camel-case
Add the render and parser to your django settings file.
.. code-block:: python
# ...
REST_FRAMEWORK = {
'DEFAULT_RENDERER_CLASSES': (
'djangorestframework_camel_case.render.CamelCaseJSONRenderer',
'djangorestframework_camel_case.render.CamelCaseBrowsableAPIRenderer',
# Any other renders
),
'DEFAULT_PARSER_CLASSES': (
# If you use MultiPartFormParser or FormParser, we also have a camel case version
'djangorestframework_camel_case.parser.CamelCaseFormParser',
'djangorestframework_camel_case.parser.CamelCaseMultiPartParser',
'djangorestframework_camel_case.parser.CamelCaseJSONParser',
# Any other parsers
),
}
# ...
Add query param middleware to django settings file.
.. code-block:: python
# ...
MIDDLEWARE = [
# Any other middleware
'djangorestframework_camel_case.middleware.CamelCaseMiddleWare',
]
# ...
By default the package uses rest_framework.renderers.JSONRenderer
. If you want
to use another renderer, the two possible are:
drf_orjson_renderer.renderers.ORJSONRenderer
or
rest_framework.renderers.UnicodeJSONRenderer
for DRF < 3.0,specify it in your django
settings file.
.. code-block:: python
# ...
JSON_CAMEL_CASE = {
'RENDERER_CLASS': 'drf_orjson_renderer.renderers.ORJSONRenderer'
}
# ...
No Underscore Before Number
As raised in this comment <https://github.com/krasa/StringManipulation/issues/8#issuecomment-121203018>
_
there are two conventions of snake case.
.. code-block:: text
# Case 1 (Package default)
v2Counter -> v_2_counter
fooBar2 -> foo_bar_2
# Case 2
v2Counter -> v2_counter
fooBar2 -> foo_bar2
By default, the package uses the first case. To use the second case, specify it in your django settings file.
.. code-block:: python
REST_FRAMEWORK = {
# ...
'JSON_UNDERSCOREIZE': {
'no_underscore_before_number': True,
},
# ...
}
Alternatively, you can change this behavior on a class level by setting json_underscoreize
:
.. code-block:: python
from djangorestframework_camel_case.parser import CamelCaseJSONParser
from rest_framework.generics import CreateAPIView
class NoUnderscoreBeforeNumberCamelCaseJSONParser(CamelCaseJSONParser):
json_underscoreize = {'no_underscore_before_number': True}
class MyView(CreateAPIView):
queryset = MyModel.objects.all()
serializer_class = MySerializer
parser_classes = (NoUnderscoreBeforeNumberCamelCaseJSONParser,)
You can also specify fields which should not have their data changed. The specified field(s) would still have their name change, but there would be no recursion. For example:
.. code-block:: python
data = {"my_key": {"do_not_change": 1}}
Would become:
.. code-block:: python
{"myKey": {"doNotChange": 1}}
However, if you set in your settings:
.. code-block:: python
REST_FRAMEWORK = {
# ...
"JSON_UNDERSCOREIZE": {
# ...
"ignore_fields": ("my_key",),
# ...
},
# ...
}
The my_key
field would not have its data changed:
.. code-block:: python
{"myKey": {"do_not_change": 1}}
You can also specify keys which should not be renamed. The specified field(s) would still change (even recursively). For example:
.. code-block:: python
data = {"unchanging_key": {"change_me": 1}}
Would become:
.. code-block:: python
{"unchangingKey": {"changeMe": 1}}
However, if you set in your settings:
.. code-block:: python
REST_FRAMEWORK = {
# ...
"JSON_UNDERSCOREIZE": {
# ...
"ignore_keys": ("unchanging_key",),
# ...
},
# ...
}
The unchanging_key
field would not be renamed:
.. code-block:: python
{"unchanging_key": {"changeMe": 1}}
ignore_keys and ignore_fields can be applied to the same key if required.
