django-pistonを使用して汎用CRUDを作成する予定です。私のサンプルコードの1つは次のとおりです
class TaskHandler(BaseHandler):
allowed_methods = ('GET','POST',)
model = Task
def read(self, name=None):
return self.model.objects.all()
def create(self, request, *args, **kwargs):
if not self.has_model():
return rc.NOT_IMPLEMENTED
attrs = self.flatten_dict(request.POST)
if attrs.has_key('data'):
# rest.POST.get('data') has csrfmiddlewaretoken as a hiddenfield
# i need to exclude it from post as my ORM is giving error message
ext_posted_data = simplejson.loads(request.POST.get('data'))
attrs = self.flatten_dict(ext_posted_data)
try:
inst = self.model.objects.get(**attrs)
return rc.DUPLICATE_ENTRY
except self.model.DoesNotExist:
inst = self.model(**attrs)
inst.save()
return inst
except self.model.MultipleObjectsReturned:
return rc.DUPLICATE_ENTRY
以下はエラーログです
