How to check password that has been hashed and salted?
In my register method, I've created a user after hashing and salting their password. And in the login method, I need to check if the user has entered the correct password. The check_password() doesn't seem to accept a salt, and when I use the default authenticate(), I get an error saying: AttributeError: 'Manager' object has no attribute 'get_by_natural_key' I'm guessing this is probably because I created a custom User model by extending AbstractBaseUser. Is there some way I can verify the password by using an existing method? Or will I have to get the salt, hash and salt the password the user just entered, and then compare with the password in the DB? My user model: class User(AbstractBaseUser): name = models.CharField(max_length=128, blank=False) created_at = models.DateTimeField(auto_now_add=True) is_admin = models.BooleanField(blank=True,default=False, verbose_name="Is admin") designation = models.CharField(max_length=90, blank=True) email = models.EmailField(max_length=160, blank=False, unique=True) USERNAME_FIELD = "email" def __str__(self): return self.name + " " + self.email Method for creating user: def register_user(self, request, **kwargs): serializer = UserSerializer(data=request.data) # handle invalid request if not serializer.is_valid(): for key, values in serializer.errors.items(): errorMsg = key + ": " + values[0].title() return Response( {"message": errorMsg}, status=status.HTTP_400_BAD_REQUEST ) name = serializer.data.get("name") email = serializer.data.get("email") password = serializer.data.get("password") user = User.objects.filter(email=email).first() … -

Telegram login widget with django TypeError: Cannot read properties of null (reading 'postMessage') with some browsers
I'm trying to implement Telegram login widget in my Django website. I'm using django-allauth and the login did work indeed for my test with Firefox browser but it failed to work on mobile devices and Chrome desktop. Authorization dialog just disappear after entering my phone number and confirming the login in Telegram messenger. I was able to run a debugger for the quickly disappearing popup window and caught this error: TypeError: Cannot read properties of null (reading 'postMessage') Login page is: <html> <body> <div> <script async src="https://telegram.org/js/telegram-widget.js?21" data-telegram-login="NameOfTelegrambot" data-size="medium" data-userpic="false" data-auth-url="https://example.com/accounts/telegram/login/"></script> </div> </body> </html> Login works with Firefox browser and I can see: Successfully signed in as TelegramUserName. And user name is shown in the upper right corner as singed in to "django-classified" But that doesn't happen in Chrome or in some popular Mobile browsers that I've tested. There is docker compose file to test the setup that can work locally after providing some Telegram Bot token in the .env file. -

What is the reason for getting HTTP 504 while trying to make HTTP call-back to retrieve further information from caller API in Django?
The above is the very high-level sequence diagram for two APIs trying to communicate with each other. The frontend does only communicate with AppOne. AppOne calls AppTwo to store some data in AppTwo's DB but before saving the data, AppTwo calls AppOne to retrieve some further information. Once AppTwo receive further information from AppOne, if everything goes as intended, AppTwo will return OK response to AppOne, finally that response will be shown to user. This works just OK on my local machine, however after deploying to Azure. The call R1 just hangs. So I added logs to monitor whats happening. I found call (a) was initiated and after line executions, call (c) is also initiated from AppTwo to AppOne. AppOne also did some thing to prepare response for the call (c) and I can see the validated response for call (c) is being printed however the response (e) does not reach AppTwo, rather I am getting HTTP 504 after some waiting time and also getting 2006 error for MySQL too. Both these apps use MySQL as backend (different databases on a single server). Additionally, in the waiting time the AppOne does not facilitate any other requests. Can anyone explain why … -

efficient way on excluding values from a database query based on timestamp
I'd like to select all instances of Link for Monitors which last_change affect a Shop. Condition: if there is a Shop linked, it cannot have a Customer linked and the other way around. Also each Monitor can only occur once with every theme. class Link(models.Model): customers = models.ManyToManyField(Customer, related_name = "%(class)s_name", related_query_name = "customer_link_qs", blank = True) shop = models.ForeignKey(Shop, on_delete = models.CASCADE, null = True, blank = True) theme = models.PositiveIntegerField("theme", default = 0, choices = [(0, 0), (1, 1)]) monitor = models.ForeignKey(Monitor, on_delete = models.CASCADE) last_change = models.DateTimeField("last change", auto_now = True) class Meta: unique_together = ["monitor", "theme"] My approach: from collections import defaultdict monitors_dict = defaultdict(list) for link in Link.objects.all() if link.monitor.store == "mystore": monitors_dict[link.monitor].append(link) last_links = [] for monitor in monitors_dict: monitor_links = monitor[1] ## list of all links for a monitor last_link = monitor_links.sort(key = lambda x: x.last_change)[-1] ## sort by last_change and take last one if last_link.shop != None: last_links.append(last_link) It feels "hacky" and I am looking for suggestions on how to make it smoother. -

Django unions and temporary fields in serializers
I have a DjangoRest view that finds several QuerySets of a Model (Item), calculates a "rank" for each item, and then passes the final list to a serializer. My "rank" field is a temporary field added by the serializer. When I try something like the this: q_a = Item.objects.filter(some filter) q_b = Item.objects.filter(some other filter) q_c = Item.objects.filter(some other filter) for item in q_a: item['rank'] = 5 #fixed rank for item in q_b: item['rank'] = calulcateRank(type_b) #my function for item in q_c: item['rank'] = calculateRank(type_c) #my function final_q = q_a | q_b | q_c serializer = ItemSertializer(final_q, many=True) My rank field is lost by the serializer. However, if I do this: q_a = Item.objects.filter(some filter) q_b = Item.objects.filter(some other filter) q_c = Item.objects.filter(some other filter) final_q = q_a | q_b | q_c for item in final_q: item['rank'] = calulcateRank() # with type logic inside now serializer = ItemSertializer(final_q, many=True) It works fine. The second version is cleaner code and probably superior but I don't really understand what the issue is and would like to know. -
