Cannot log in onto Django Admin Panel with a custom user
I created a custom user model shown below: from django.db import models from django.contrib.auth.models import ( BaseUserManager, AbstractBaseUser, PermissionsMixin ) class UserManager(BaseUserManager): def create_user(self, username, password=None): user = self.model(username) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, username, password, **kwargs): user = self.create_user(username,password=password) user.is_admin = True user.save(using=self._db) return user class tgUser(AbstractBaseUser, PermissionsMixin): username = models.CharField(primary_key=True, max_length=50) id = models.CharField(max_length=50) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) photo_url = models.CharField(max_length=200) is_admin = models.BooleanField(default=False) objects = UserManager() USERNAME_FIELD = "username" def __str__(self): return f"{self.first_name} ({self.last_name})" In the settings.py, I specified: AUTHENTICATION_BACKENDS = ( 'django.contrib.auth.backends.ModelBackend', ) SITE_ID = 1 AUTH_USER_MODEL = "table.TgUser" ACCOUNT_EMAIL_REQUIRED = False # ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_USER_MODEL_USERNAME_FIELD = "username" Yet the admin panel still displays "Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive." on login. How can I solve this? -
Python returning false on checking if a string exists in list even when it does
I imported a model(named Feature) and set it to a list in Django posts = Feature.objects.order_by('name') upon calling the 5th element print(posts[5]) this displays apple in shell which is the 5th object however on checking it with a if condition it returns false if 'apple' in posts: print("yes") else: print("no") and it prints no .. why is this happening even tho apple exists in the list -
Custom user model in Django - Create a stripe account (Django - Python)
When a user is created on django admin, I am trying to automatically create a user in Stripe. I do not understand why objects = CustomUserManager() is not being executed. Here is the model file class CustomUser(AbstractUser): username = None email = models.EmailField(_('email address'), unique=True) name = models.CharField(verbose_name=_("first name"), max_length=50) stripe_customer_id = models.CharField(max_length=120) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name'] objects = CustomUserManager() def __str__(self): return self.name Here is the customUserManager class CustomUserManager(BaseUserManager): def create_user(self, email, password, name,**extra_fields): if not email: raise ValueError(_('The Email must be set')) email = self.normalize_email(email) customer = stripe.Customer.create( email=email, name=name, ) user = self.model(email=email,name=name, stripe_customer_id=customer.id ,**extra_fields) user.set_password(password) user.save() return user It seems like the create_user is not triggered when I create a user from the panel. If I comment out objects = CustomUserManager() I am still able to create users on the admin panel without any errors. -

How to filter Django Model instances based on a function defined inside the model?
I have a model for an item, it has a function that tells if the item is still on auction depending on an end date. class Catalogue(models.Model): name = models.CharField(max_length=256) owner = models.ForeignKey(User, on_delete=models.CASCADE) end_date = models.DateTimeField() def auction_status(self): now = timezone.now() return now < self.end_date In a class view i want to filter only those instances where the auction_status is true. Something along the lines of : class AuctionOverView(ListView): model = Catalogue template_name = 'administration/catalogue.html' def get_queryset(self): try: return Catalogue.objects.filter(auction_status=False) except: raise Http404() But i obviously can not filter based on a function definition.

Accessing the attributes/elements of a form in Django
Hello so I've a form and I'm trying to make it so that when that form is validated. But before it is saved. It will create a new instance of a EC_Node and save the command given in the Command_Form not only to the Command_Node but to the EC_Nodes. Which should have a manytoone relationship with the Command_Nodes and which should record all commands send to a command_node. But this will only work if when entering a command for the Command_Node I also capture that in a EC_Node. Which I don't know how to do exactly although I'm some ideas. So any advice would be greatly appreciated. Relevant Code follows. Relevant views.py def update(request, host_id): host_id = Command_Node.objects.get(pk=host_id) form = Command_Form(request.POST or None, instance=host_id) if form.is_valid(): # Original suggestion was command_form = Command_Form.objects.first() command_form = form['host_id'] command_form.EC_Node_set.all() # <- not sure with all _ and Maj here form.save() return redirect('home') return render (request, 'update.html', {'host_id':host_id,'form':form}) forms.py class Command_Form(ModelForm): class Meta: model = Command_Node fields = ('host_id','current_commands') host_id = forms.ModelChoiceField( required=True, queryset=Beacon.objects.all(), widget=forms.SelectMultiple( attrs={ 'class': 'form-control' }, ) ) current_comamnds = forms.ChoiceField( required=True, choices=CHOICES ) def save(self, **kwargs): EC_Node.objects.create( command=self.cleaned_data["current_commands"], Command_node=self.instance ) return super().save(**kwargs) models.py class Command_Node(models.Model): host_id = models.ForeignKey(Beacon, on_delete=models.CASCADE) … -

How to integrate Bokeh Server into Django
Currently I have a Bokeh server running. I can access it and when I push some buttons then Python code runs in the background and finally a figure is plot. Now I need to add some things: I want users to authenticate. Users should be able to save results to a database. Some general data (costs, the same for everybody) should also be obtained from a database. User sessions should be stored. In the end multiple apps will be made available to users. Not all users will have access to all apps. Authentication should solve this. So I think I should integrate the Bokeh server into Django using server_document(). However, I am not able to find a minimal working example. It would be nice if that example includes the topics from my list. -
Django Channels Rest Framework V3 @model_observer message is None
I tried to find anything in the documentation of model observer which could explain under which conditions the model observer is called with message = None, but there was nothing particularly hinting into the right direction. From what I unterstand from the example: class MyConsumer(GenericAsyncAPIConsumer): queryset = User.objects.all() serializer_class = UserSerializer @model_observer(Comments) async def comment_activity( self, message: CommentSerializer, observer=None, subscribing_request_ids=[] **kwargs ): await self.send_json(message.data) @comment_activity.serializer def comment_activity(self, instance: Comment, action, **kwargs) -> CommentSerializer: '''This will return the comment serializer''' return CommentSerializer(instance) @action() async def subscribe_to_comment_activity(self, request_id, **kwargs): await self.comment_activity.subscribe(request_id=request_id) The message should be the output of the CommentSerializer so the only way a message to become null is, if the serializer would return nothing ?! To check if this is the case I added logs prints which sadly indicate that the serializer is receiving data and thous there is no reason the message could be None. Its also occurring only from time to time so any advice about misunderstanding of how the observer works internally will be highly appreciated. In our implementation: class StorageConsumer(ListModelMixin, AsyncAPIConsumer): """ Async API endpoint that allows Storage updates to be pushed.

How to have dedicated instances for celery containers when deploying django project using docker-compose on elastic beanstalk?
I have a web-app that uses celery for heavy calculations. It was deployed on AWS with elastic beanstalk, using docker-compose. The broker is Amazon SQS, while redis is used as result backend. Here is the docker-compose file to understand the structure: version: '3.8' volumes: data: driver_opts: type: "nfs" o: "addr=XXXXXXXXXXXXXXXXXXXXXXX,rw,nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport" device: ":/" static: services: web: build: ./web command: > bash -c "python3 manage.py migrate && python3 manage.py collectstatic --noinput && gunicorn APPNAME.asgi:application --access-logfile '-' --error-logfile '-' --capture-output --enable-stdio-inheritance -k uvicorn.workers.UvicornWorker -b 0.0.0.0:8000" volumes: - data:/home/webserver/data/ - static:/home/webserver/static/ ports: - "8000:8000" depends_on: - redis celery: build: ./web command: celery -A APPNAME worker -Ofair -l INFO volumes: - data:/home/webserver/data/ depends_on: - web redis: image: redis:6.2.6-alpine ports: - "6379:6379" nginx: build : ./nginx ports: - "80:80" depends_on: - web volumes: - static:/home/webserver/static/ It works well, including the celery tasks. Now, I would like to separate the web/redis/nginx services from the celery containers that would have their own dedicated instances, with the ability to scale. Is there a proper way to do that (using CLI)? Should I consider separate beanstalk applications? -

How Can I Add Country Flags to Django Phonenumber Widget
I have used django-phonenumber-field in my project with Babel which is working fine with drop down of all countries with their international dialing code. My problem is that I want each country flag attached to their names so that the phonenumber field will be smaller. Attached is the what I presently have. This is exactly what I want to achieve with django-phonenumber-field. And you can observe that my phone number fields are two; one has the international code and the other field is where the phone number is to be entered whereas I want all in one field with Countries Flags. Anticipating your prompt answer, thanks. -

Is the location or scope important in a web push service worker?
I have a Django web app that contains a service worker designed for handling push notifications. Everything is working beautifully. In the many articles, tutorials and documentation it is written that the location and scope of service workers is important and to make sure to put it at the root of the domain. See for example this article, that states: Service worker file must registered at the root directory of your website. And: I’ve spend 15 hours to learn that fact. You guys are lucky !
