Can login in production but not in development [closed]
I have backed up my postgres database from production and am using it in my dev environment. Everything works as it does in production aside from authentication. When I try to login with the correct details it fails. I thought this could be because of something in settings.py however I don't really have anything added (maybe I need something?) -
How to perform a validation according to types, instead of field by field, in Django?
In Django, before calling the "save" method of an instance, it is possible to implement your own validation by defining the "clean" or "full_clean" method in the corresponding model. The problem is that in that case it would be necessary to check each of the fields and add a particular behavior; however, what I want is a more general behavior, so that if you enter a type that does not match the one defined in the model, such field will be saved as None. Example: Let's suppose an application, with the following model: class Company(models.Model): name = models.CharField(max_length=255, null=True, blank=True) date_of_formation = models.DateTimeField(null=True, blank=True) assets = models.FloatField(null=True, blank=True) And assume we have these 3 json data inputs: input_1 = { "pk": 1, "name": "Alexander", # right type "date_of_formation": "2021-01-01", # right type "assets": 500023.658 # right type } input_2 = { "pk": 2, "name": ["Alex", "Vero"], # WRONG type "date_of_formation": "2021-01-01", # right type "assets": 523658 # right type } input_3 = { "pk": 3, "name": ["Alex", "Vero"], # WRONG type "date_of_formation": 65, # WRONG type "assets": "523658" # WRONG type } The behavior I would expect is something like: Company.objects.create(**input_1) Company.objects.create(**input_2) Company.objects.create(**input_3) >> Company.objects.get(pk=1).__dict__ { "id": 1, "name": "Alexander", … -
Why we cannot use select_related for ManyToMany fields
let's say i have the following fields class ABC(models.Model) whatever=models.ManyToManyField('DEF') class DEF(models.Model) something=models.CharField() I want to retrieve ABC along side each DEF it's connected to, why i cannot do this ? ABC.objects.filter(pk=123).select_related('DEF').get() I believe we can do this in one SQL query like so select * from ABC inner join ABC_DEF on ABC.id = ABC_DEF.ABC_ID inner join DEF on DEF.id = ABC_DEF.DEF_ID -
How to filter Django serializer data?
I'm trying to filter data based on userName in JWT. This is how I've been trying to do it: views.py: class TestView(APIView): permission_classes = (IsAuthenticated,) def get(self, request): token = request.META.get('HTTP_AUTHORIZATION', " ").split(' ')[1] data = {'token': token} try: valid_data = VerifyJSONWebTokenSerializer().validate(data) user = valid_data['user'] request.user = user person = Person.objects.filter(userName=request.user) except ValidationError as v: print("validation error", v) return Response(person[0]) This works as I can get the Person data with print("Person: ", person[0]). The return Response(person[0]) however returns an error: TypeError: Object of type Person is not JSON serializable. I guess I could use a serializer class to return a valid JSON, am I right? I have this in my serializers.py: class TestSerializer(serializers.ModelSerializer): class Meta: model = Person fields = '__all__' I just don't know how to use this with my view. If I use serializer instead of person = Person.objects.filter(userName=request.user), how is the filtering supposed to be done? Please correct me if I'm not on right track at all. -

Threading: Restarting a thread
I have a django project that I am currently working on. I have several threads that I use to fill a database through API requests when the user asks for a database update using a button. This works great. My problem is that I would like users to be able to refresh the database more than once while the server is active (in the future). Since threads can't be restarted once they finish, I'm not really sure how to proceed to achieve what I want. Here are my threads: agencies_thread = threading.Thread(target=fill_agencies, name="Database Updater1") companies_thread = threading.Thread(target=fill_companies, name="Database Updater2") contracts_thread = threading.Thread(target=fill_contracts, name="Database Updater3") orders_thread = threading.Thread(target=fill_orders, name="Database Updater4") projects_thread = threading.Thread(target=fill_projects, name="Database Updater5") resources_thread = threading.Thread(target=fill_resources, name="Database Updater6") I'm thinking that the threads have to be recreated everytime someones presses the button, but adding those lines ^^ in my views.py function that manages the database loading can't really work considering my function: elif urlRequest[:12] == 'loading.html': # PAGE DE CHARGEMENT global updateValue if updateValue == 0: agencies_thread.start() companies_thread.start() contracts_thread.start() orders_thread.start() projects_thread.start() resources_thread.start() updateValue = 1 updateState = 0 if agencies_thread.is_alive(): agenciesState = 'en cours de chargement' else: agenciesState = 'Chargement terminé' updateState += 1 if companies_thread.is_alive(): companiesState = 'en … -

I have a ModelViewSet that looks like the following class BusinessViewSet(ModelViewSet): filterset_class = BusinessFilter serializer_class = BusinessSerializer ordering_fields = [ "source", "xl_source", "company_name", "contact_title", "category", "contact_name", "description", "tags", "business_hours", "location", "website", "phone", "email", "social_media", "address", "is_ecommerce", "is_verified", "ownership", "supplemental_information", "products", "location_street", "location_city", "location_state", "location_zip", ] def get_queryset(self): referer = self.request.META["HTTP_REFERER"] try: source = referer.split("source=")[1] except Exception as e: print(e) source = None if source == None: queryset = Business.objects.all() elif source == 'SBASpecial': queryset = SBABusiness.objects.all() self.serializer_class = SBABusinessSerializer self.filterset_class = SBABusinessFilter self.ordering_fields = [ 'name_and_trade_of_firm', 'contact', 'address_city', 'capabilities_narrative', 'ownership_self_certs', 'email_address', 'www_page_url', 'phone_number', 'year_established', 'keywords', 'naics_codes', ] else: queryset = Business.objects.filter(xl_source=source) return queryset As you can see, if the source is SBASpecial, I try to change the class variables serializer_class and ordering_fields inside get_queryset. Obviously this is not working. I've looked at the django rest framework documentation and there isn't anything there that can help me with this problem. What can I do? Any help is appreciated. Thanks in advance
