How to use get_or_create? Error: get() returned more than one Patient -- it returned 7
I have a function for fetch API where I create a Django model object for each object in the JSON and store the data in django model. The problem here is everytime I call the route it creates the records again and again, because I use create method, but I made an research that the best way to stop that is to use get_or_create. So, I tried this method but it looks like I missed something, because I got an error: feedback.models.Patient.MultipleObjectsReturned: get() returned more than one Patient -- it returned 7! this is my code before I have 2 for loops so I can loop through every patient and then through every role and save patient with a role: # FetchApi for Patients def fetchapi_patients(request): url = 'http://localhost:8000/core/users/roles/patient' headers={"Authorization":"Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6Imhha2FuQGdvLmNvbSIsImV4cCI6MTYxMDAxMTM0MSwib3JpZ19pYXQiOjE2MTAwMDc3NDF9.k2204d094DNUbEfFt8M_7chukOSjWWwfesPOH5jIiP8"} response = requests.get(url, headers=headers) #Read the JSON patients = response.json() #Create a Django model object for each object in the JSON and store the data in django model (in database) for patient in patients: Patient.objects.create(first_name=patient['first_name'], last_name=patient['last_name'], email=patient['email'], coreapi_id=patient['ID']) for role in patient['Roles']: Role.objects.create(role_name=role['name']) return JsonResponse({'patients': patients}) this is when I tried to use get_or_create method: for patient in patients: patientDatabase, created = Patient.objects.get_or_create(first_name=patient['first_name'], last_name=patient['last_name'], email=patient['email'], coreapi_id=patient['ID']) for role in … -

How to apply exclude for first resultant item of select_related() query in django
I am doing a left join using select_related() and then excluding few things based on condition using below code class ActiveclientViewSet(viewsets.ModelViewSet): queryset = Ruledefinitions.objects.select_related('pmdclinicalruleid').filter(pmdclinicalruleid__effectivedate__lt = timezone.now(),pmdclinicalruleid__retireddate__gt = timezone.now()).exclude(Q(rulename__isnull=True) | Q(rulename__exact='') | Q(rulename__startswith='OptumFormulary')) The above code applies exclude for entire select_related results. Instead i need to apply exclude only for first result item from select_related(). Any way to implement this? -

Django form data with azure logic apps
I got a django form data which I need to post to azure logic app. When I post the data I get this error: {"error":{"code":"NoResponse","message":"The server did not receive a response from an upstream server. Request tracking id '08585915990752009043423379830CU49'."}} When I check azure logs I see this error: BadRequest. The property 'content' must be of type JSON in the 'ParseJson' action inputs, but was of type 'application/x-www-form-urlencoded'. So as I understand I need to change this data to json as its sent as application/x-www-form-urlencoded. So My question is how can I do that? I'm new to django so any help would be great.

Nested subquery distinction to annotate sum
So I'd like to annotate a sum to a queryset, which has a little calculation rule with vars from remote tables. facturen = Factuur.objects.values('inkoopopdracht').filter( inkoopopdracht=OuterRef('pk'),) gefactureerd = facturen.annotate( gefactureerd=Sum(Case( When( factuurpost__inkooppost__btw__systematiek=2, then=(F( 'factuurpost__inkooppost__aantal')*F('factuurpost__inkooppost__eenheidprijs'))), default=F( 'factuurpost__inkooppost__aantal')*F('factuurpost__inkooppost__eenheidprijs')*( 1+F('factuurpost__inkooppost__btw__percentage')), output_field=DecimalField(), )), ).values('gefactureerd') qs = qs.annotate( factuursom=Subquery(gefactureerd.values( 'gefactureerd'), output_field=DecimalField()), ) The result of the above query is satisfactory. Except when there is a multiple of 'factuurpost'. In this case the sum seems to be multiplied with factuurpost instances. A fix for this, would be 'distinct=True' on the Sum. However since it only distincts values and not instances, this introduces a new problem. Similar values are no ignored, yielding the wrong sum. This seems to be an issues other people have come across with as well, e.g. : Django Count and Sum annotations interfere with each other Now, I used the solution there, with the subquery. I tried to nest the subquery to no avail. Does anyone see a potential solution to have it calculate the right sum in all cases? -

I'm following a tutorial on https://medium.com/@nipun.357/aes-encryption-decryption-java-python-6e9f261c24d6 for encryption and decryption in python. I'm getting error in my case: raise TypeError("Object type %s cannot be passed to C code" % type(data)) TypeError: Object type <class 'str'> cannot be passed to C code The code is coverting string to bytes then Why am I getting this error. Why code is not working and how can I reesolve this import base64 import hashlib from Crypto import Random from Crypto.Cipher import AES def get_private_key(secret_key, salt): block_size = 16 pad = lambda s: s + (block_size - len(s) % block_size) * chr(block_size - len(s) % block_size) unpad = lambda s: s[0:-ord(s[-1:])] iv = Random.new().read(AES.block_size) # Random IV return hashlib.pbkdf2_hmac('SHA256', secret_key.encode(), salt.encode(), 65536, 32) def encrypt_with_AES(message, secret_key, salt): block_size = 16 pad = lambda s: s + (block_size - len(s) % block_size) * chr(block_size - len(s) % block_size) unpad = lambda s: s[0:-ord(s[-1:])] iv = Random.new().read(AES.block_size) # Random IV private_key = get_private_key(secret_key, salt) message = pad(message) cipher = AES.new(private_key, AES.MODE_CBC, iv) cipher_bytes = base64.b64encode(iv + cipher.encrypt(message)) return bytes.decode(cipher_bytes) def decrypt_with_AES(encoded, secret_key, salt): block_size = 16 pad = lambda s: s + (block_size - len(s) % block_size) * chr(block_size - len(s) % block_size) unpad = lambda s: …
