I am trying to use the CamelCaseJSONParser on an api that takes in an object where some of the keys are dynamic UUID values. I've come across an issue where the parser underscore-izes these UUID values resulting in invalid UUIDs. I can get around it by using ignore_fields, but I feel that UUIDs don't ever need to be underscore-ized.
I'm able to fix this issue by overriding the underscoreize util like so:
def underscoreize(data, **options):
from uuid import UUID
ignore_fields = options.get("ignore_fields") or ()
ignore_keys = options.get("ignore_keys") or ()
if isinstance(data, dict):
new_dict = {}
if type(data) == MultiValueDict:
new_data = MultiValueDict()
for key, value in data.items():
new_data.setlist(camel_to_underscore(key, **options), data.getlist(key))
return new_data
for key, value in _get_iterable(data):
if isinstance(key, str):
new_key = camel_to_underscore(key, **options)
# START CHANGES
try:
UUID(key)
except ValueError:
# key is not a UUID, so it's okay to add underscores
new_key = camel_to_underscore(key, **options)
else:
new_key = key
# END CHANGES
else:
new_key = key
if key not in ignore_fields and new_key not in ignore_fields:
result = underscoreize(value, **options)
else:
result = value
if key in ignore_keys or new_key in ignore_keys:
new_dict[key] = result
else:
new_dict[new_key] = result
if isinstance(data, QueryDict):
new_query = QueryDict(mutable=True)
for key, value in new_dict.items():
new_query.setlist(key, value)
return new_query
return new_dict
if is_iterable(data) and not isinstance(data, (str, File)):
return [underscoreize(item, **options) for item in data]
return data
