SetPasswordForm: clean only if new_password1 or new_password2 field is set
I need to validate updatePasswordForm only if new_password1 or new_password2 are not empty. I want to make the password fields optional, these are only for update the password. The view not only has the updatePasswordForm form.

Django Model Mixin: Adding loggers to model save() and delete() using Mixins
I would like all my models to inherit from a single "loggingMixin" class. The problem is that, instead of using the save() defined in the LoggingMixin, the standard save() is used. (none of the print statements in the loggingmixin are executed and my traceback always referenced the object.save() from my views and not the error raised in the loggingmixin. all other logs works as they should and i can save and delete objects. but nothing gets logged. thanks in advance for the help! import logging logger = logging.getLogger(__name__) ## this file defines a mixin to logg all saves, updates, deletes and errors class LoggingMixin: def save(self, *args, **kwargs): try: print("---------------------------------------------------------------1") if hasattr(self.pk): print("---------------------------------------------------------------2") if self.pk is None: # Object is new print("---------------------------------------------------------------3") super(LoggingMixin, self).save(*args, **kwargs) logger.info(f"{self._meta.db_table} object saved: " + str(str(self).split('\n')[1])) else: # Object is being updated print("---------------------------------------------------------------4") super(LoggingMixin, self).save(*args, **kwargs) logger.info(f"{self._meta.db_table} object updated: " + str(str(self).split('\n')[1])) else: # Object is being updated print("---------------------------------------------------------------5") super(LoggingMixin, self).save(*args, **kwargs) logger.info(f"{self._meta.db_table} object updated: " + str(str(self).split('\n')[1])) # error when saving except Exception as e: print("-------------------------------------------------------------6") logger.error(f"Error saving {self._meta.db_table} object: " + str(str(self).split('\n')[1]) + f"Error: {e}") raise e def delete(self, *args, **kwargs): # delete log try: super(LoggingMixin, self).delete(*args, **kwargs) logger.info(f"{self._meta.db_table} object deleted.

Django Mem Cache Through IIS - Not Working as Expected
I'm using Django with no caching options meaning it defaults to memory cache. Caching is simple: Set Cache cache.set('chart_' + str(chartId), chart, 3600) Reset Cache when model is saved @receiver(pre_save, sender=DashboardChart) def increment_dashboard_chart_version(sender, instance, **kwargs): instance.version = instance.version + 1 # Resets cache cache.set('chart_' + str(instance.pk), None, 3600) Access cache cache.get('chart_' + str(chartId)) I'm running Django in production through IIS. What I'm finding is if I save the Chart model, the cache gets reset as expected. However, when reloading the page a few times the chart varies at random between the old version and the new version. My suspicion is that the different IIS worker threads are keeping their own memory version of the cache. Meaning there is not one global cache shared between the different IIS worker threads. As I randomly reload the page, the worker access changes and the cache version I get back is different. Any idea if I'm on the right path and how to solve this issue ? -
Getting a use a thread or sync_to_async error
So Im working on a Django web chat. I just switched my db structure to be able to support groupchats. I changed the code so far and Im struggling to figure out how to fix the following error. django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async.

Django: converting view function to class-based view. Error during login to Admin panel: matching query does not exist
I'm learning how to convert old view.py functions to class-based views. I started with a simple function that displayed a page with my essays, plus, I had a newsletter form and a draft of a comment form (but not attached to DB). I decided to not develop this comment form further in a simple function, but to rebuild all of it to class-based view to learn a better and cleaner approach. I've encountered a problem that I have no idea how to solve. Error: matching query does not exist. And Exception Value: EssayCls matching query does not exist. Most likely I break the logic that connects my model to my DB. I'm looking for suggestions on how to solve issues in my code and suggestions about topics I should learn more about to make this kind of development less cumbersome. Before I rebuild my view, things were working fine and looked like this: views.py: from django_user_agents.utils import get_user_agent from .models import EssayCls, SendMeMessage from .forms import CommentForm def my_essays(request, home_view_author_slug): user_agent = get_user_agent(request) try: selected_essay = EssayCls.objects.get(slug=home_view_author_slug) if request.method == 'GET': user_feeDBack = UserFeeDBack() else: """ The incoming request from Django will have a POST property which contains any submitted … -
Search results doesn't show in the template (Django)

Every time I try to search, it redirect me to the search template but not showing the data from the database. No error message. Here's my code... models.py class Event(models.Model): eventname = models.CharField(max_length = 100) class months(models.TextChoices): JANUARY = 'January', _('January') FEBRUARY = 'February', _('February') MARCH = 'March', _('March') APRIL = 'April', _('April') MAY = 'May', _('May') JUNE = 'June', _('June') JULY = 'July', _('July') AUGUST = 'August', _('August') SEPTEMBER = 'September', _('September') OCTOBER = 'October', _('October') NOVEMBER = 'November', _('November') DECEMBER = 'December', _('December') month = models.CharField( max_length= 10, choices=months.choices, default=months.JANUARY, ) day = models.IntegerField() year = models.IntegerField() area = models.ForeignKey(Area, related_name = 'events', blank=True, null=True, on_delete = models.CASCADE) guest = models.ForeignKey(Guest, related_name = 'events', on_delete = models.CASCADE) recorded_by = models.ForeignKey(Userprofile, related_name = 'events', on_delete = models.CASCADE) def __str__(self): return self.eventname search_bar.html #the search bar in the template <div class="search"> <form method="post" action="{% url 'event_search' %}" autocomplete="off"> <br> {% csrf_token %} <input type="text" name="event_srch" placeholder="Search Event"> <input type="submit" name="submit" value="Search" style="width: 24%"></p> </form> </div> views.py def event_search(request): if request.method == "POST": event_search = request.POST.get('event_srch') events … -

Django keyword error but print kwargs shows the key
I have this URL and I send the currently logged in user's id (viewer (33)) and the id of the user being looked at (user (1)) in the URL: path("users/<int:viewer>/<int:user>/profile/", OtherProfile.as_view()), Here is the view handling that URL: class OtherProfile(generics.RetrieveAPIView): permission_classes = [permissions.IsAuthenticated] serializer_class = ProfileSerializer name = "other-profile" lookup_field = "user" def get_queryset(self): breakpoint() viewer = self.kwargs["viewer"] user = self.kwargs["user"] return Profile.objects.all().filter(user_id=user) There is a breakpoint here and the result of print(self.kwargs["viewer"]) gives 33 which is correct print(self.kwargs["user"]) gives 1 which is also correct Here is the profile serializer as specified in the serializer_class: class ProfileSerializer(serializers.ModelSerializer): location = serializers.SerializerMethodField() user = UserSerializer() followers = serializers.SerializerMethodField() class Meta: model = Profile fields = [ "id", "background", "photo", "first_name", "middle_name", "last_name", "birthdate", "gender", "bio", "occupation", "is_verified", "verification", "website", "location", "user", "followers", "created_at", "updated_at", ] def get_location(self, obj): location_obj = Location.objects.filter(profile=obj.id) if location_obj: location_obj = Location.objects.get(profile=obj.id) location = LocationSerializer(location_obj) return location.data def get_followers(self, obj): breakpoint() followers = Follow.objects.filter(followee=obj.user.id) return followers.count() I put a breakpoint on the get_followers method so I can look at the data. print(self.context["view"].kwargs) - prints ["viewer", "user"] My question: Why does print(self.context["view"].kwargs["user"]) print 33 when on the view the kwargs user should be 1? Why does it give me … -
I can´t publish MQTT messages after a few days
I'm using "mqttasgi" as library with Django justo to listen and posting many messages. However, for some reason after a few days it is no longer possible to continue posting messages. It should be noted that I am using the amazon login with "mqttasgi" and a level 1 of QO(because AWS doesn't allow a level 2 of QO). This is my procfile mqttasgi -H $MQTT_URL -p $MQTT_PORT -v 2 -C $TLS_CERT -K $TLS_KEY -S $TLS_CA iot_stracontech.asgi:application``` and this is my consumer.py from mqttasgi.consumers import MqttConsumer from mqtt_handler.tasks import processmqttmessage import json class MyMqttConsumer(MqttConsumer): async def connect(self): await self.subscribe('tpx/things/+/uplink', 0) await self.channel_layer.group_add("stracontech", self.channel_name) async def receive(self, mqtt_message): print('Received a message at topic:', mqtt_message['topic']) print('With payload', mqtt_message['payload']) print('And QOS:', mqtt_message['qos']) dictresult = json.loads(mqtt_message['payload']) jsonresult = json.dumps(dictresult) processmqttmessage.delay(jsonresult, mqtt_message['topic']) pass async def publish_results(self, event): data = event['result'] await self.publish("stracontech/procesed/" + event['result']['device_id'] + "/result", json.dumps(data).encode('utf-8'), qos=1, retain=False) async def disconnect(self): await self.unsubscribe('tpx/things/+/uplink') I want to know if exist a way to know why does it stop publishing messages, anyway to do a debug or see the logs? Pd: @Santiago Ivulich maybe you can give me a hand with that. -
