Я пытаюсь реализовать простую службу Django с RESTful API, используя deliciouspie. Моя проблема в том, что когда я пытаюсь создать WineResource с помощью PUT, он работает нормально, но когда я использую POST, он возвращает ошибку HTTP 501. Читая документацию о вкусных пирогах, кажется, что это должно просто работать, но это не так.
Вот мой код api.py:
class CustomResource(ModelResource):
"""Provides customizations of ModelResource"""
def determine_format(self, request):
"""Provide logic to provide JSON responses as default"""
if 'format' in request.GET:
if request.GET['format'] in FORMATS:
return FORMATS[request.GET['format']]
else:
return 'text/html' #Hacky way to prevent incorrect formats
else:
return 'application/json'
class WineValidation(Validation):
def is_valid(self, bundle, request=None):
if not bundle.data:
return {'__all__': 'No data was detected'}
missing_fields = []
invalid_fields = []
for field in REQUIRED_WINE_FIELDS:
if not field in bundle.data.keys():
missing_fields.append(field)
for key in bundle.data.keys():
if not key in ALLOWABLE_WINE_FIELDS:
invalid_fields.append(key)
errors = missing_fields + invalid_fields if request.method != 'PATCH' \
else invalid_fields
if errors:
return 'Missing fields: %s; Invalid fields: %s' % \
(', '.join(missing_fields), ', '.join(invalid_fields))
else:
return errors
class WineProducerResource(CustomResource):
wine = fields.ToManyField('wines.api.WineResource', 'wine_set',
related_name='wine_producer')
class Meta:
queryset = WineProducer.objects.all()
resource_name = 'wine_producer'
authentication = Authentication() #allows all access
authorization = Authorization() #allows all access
class WineResource(CustomResource):
wine_producer = fields.ForeignKey(WineProducerResource, 'wine_producer')
class Meta:
queryset = Wine.objects.all()
resource_name = 'wine'
authentication = Authentication() #allows all access
authorization = Authorization() #allows all access
validation = WineValidation()
filtering = {
'percent_new_oak': ('exact', 'lt', 'gt', 'lte', 'gte'),
'percentage_alcohol': ('exact', 'lt', 'gt', 'lte', 'gte'),
'color': ('exact', 'startswith'),
'style': ('exact', 'startswith')
}
def hydrate_wine_producer(self, bundle):
"""Use the provided WineProducer ID to properly link a PUT, POST,
or PATCH to the correct WineProducer instance in the db"""
#Workaround since tastypie has bug and calls hydrate more than once
try:
int(bundle.data['wine_producer'])
except ValueError:
return bundle
bundle.data['wine_producer'] = '/api/v1/wine_producer/%s/' % \
bundle.data['wine_producer']
return bundle
Любая помощь приветствуется! :-)
