mqtt over socket in django-channels
I am trying to start a mqtt broker over websocket in django-channels to publish data over specific topics to authorized users. I have defined a url to filter mqtt request in a specific consumer where I am accepting the socket request. This all part is working fine but when I am establishing a mqtt connection the socket is restarting again and again, and I don't have any idea why this is happening!? and also it's a bit confusing how will i send the message from my views. Code snippets: routing.py from django.urls import re_path from . import consumer websocket_urlpatterns = [ re_path(r'ws/data/(?P<room_name>\w+)/(?P<auth_data>\S+)/$',consumer.ChatConsumer.as_asgi()), re_path(r'mqtt', consumer.ChatTwoConsumer.as_asgi()) ] consumer.py class ChatTwoConsumer(WebsocketConsumer): def connect(self): print('here') self.accept() -
Why does form.is_valid return false. Please advice
I have a project where one books a room online then is directed to the checkout page where you input a phone which is required in the backend.

Django Two Models CreateView
Good Evening / Hello.... I have in essence three models: User / UserAddress / Organisation - simplified for brevity User(model.Models): id = uuid..... address = models.ForeignKey(Address.....) member_of = models.Many2Many(Organisation..... Adress(model.Models): id = uuid ..... Organisation(model.Models): id = uuid .... I have just started practicing MBV class forms. When I create a user - The member_of is filtered in the model.form with no issues - works great. The issue im having is using a create view to Add a user and address on one form. What i have tried: 1) class ActorUserCreateView(LoginRequiredMixin, CreateView): template_name = 'user/create.html' form_class = CreateNewUser address_form_class = PostalAddressForm success_url = reverse_lazy('user_list') def post(self, request, *args, **kwargs): address_form = PostFormSet(request.POST) logging.info("ADDRESS FORM") logging.info(address_form) user_form = self.get_form() logging.info(user_form) if address_form.is_valid() and user_form.is_valid(): return self.form_valid(address_form=address_form, form=user_form) else: messages.add_message(request, messages.WARNING, 'Error in Form') return super().post(request, *args, **kwargs) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['address'] = PostFormSet return context PostFormSet is in forms as: PostFormSet = formset_factory(PostalAddressForm, max_num=1) This is beginning to put me off CBV's - function based views seem a lots easier but ive been told this is the to go.... The errors: in the terminal - ive run logging on the address form: <tr><td colspan="2"><ul class="errorlist nonfield"><li>(Hidden field TOTAL_FORMS) … -

Django forms for sex

Can I pass additional data to the template if I use UpdateView?

What is AWS_DEFAULT_ACL supposed to be used in django-storages?
I'm a bit of a newbie to django-storages and I'm confused about the purpose of its AWS_DEFAULT_ACL settings variable. I gather that when it's set to None, the bucket policy on my AWS S3 bucket will be honored. That seems to indeed be true. I've turned off public access to my bucket and am using the following bucket policy: { "Version": "2012-10-17", "Id": "Policy1621539673651", "Statement": [ { "Sid": "Stmt1621539665305", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::063896663644:user/mylogin" }, "Action": [ "s3:GetObject", "s3:GetObjectAcl", "s3:PutObject", "s3:PutObjectAcl" ], "Resource": "arn:aws:s3:::mybucket/*" }, { "Sid": "Stmt1621539600741", "Effect": "Allow", "Principal": { "AWS": "*" }, "Action": "s3:GetObject", "Resource": "arn:aws:s3:::mybucket/static/*" } ] } I can run python manage.py collectstatic and it uploads files without an issue. However, if I change AWS_DEFAULT_ACL to 'public-read', I get errors when running collectstatic.

How to run a terminal command in Django app?
I want to execute a terminal command whenever I visit the index page in my Django app. I've done it outside of the Django app and it worked. Outside of my Django app I ran: import subprocess subprocess.run('python hello.py') The hello.py file which contains a regular print statement print('Hello') and in the terminal from where I ran the command using the above script, it of course prints "Hello" like a charm. My question is, is it possible to run something like below in my Django app? def index(request): subprocess.run('python manage.py process_tasks') today = datetime.now() schedule_time = datetime(year=today.year, month=today.month, day=today.day, hour=today.hour + 5, minute=today.minute + 1, tzinfo=pytz.UTC) run_until = datetime(year=today.year, month=today.month, day=today.day, hour=today.hour + 5, minute=today.minute + 1, tzinfo=pytz.UTC) print_hello(schedule=schedule_time, repeat=20, repeat_until=run_until) return HttpResponse(f'Background task running...') By including this command subprocess.run('python manage.py process_tasks') in the view function it will at least eliminate me opening another terminal to run python manage.py process_tasks to get the app to work in the background for me. The app went to the page successfully but the background tasks aren't picking up and in the terminal it is saying ModuleNotFoundError: No module named 'background_task'. Here's the image with the error message for a better understanding. Thanks! ModuleNotFoundError -

Django how to generate a filtered queryset
I have got 2 models. Asset and Asset_Type. In my asset_type detail view i would like to list all assets of that asset type. I think I have to use models.Asset.queryset().filter() but i can't get it to work. On my template I would like to loop though the list with a 'for' (example: object in list) and print the values like this {{ object.name }} models.py class Asset(models.Model): # Relationships room = models.ForeignKey("asset_app.Room", on_delete=models.SET_NULL, blank=True, null=True) model_hardware = models.ForeignKey("asset_app.Model_hardware", on_delete=models.SET_NULL, blank=True, null=True) # Fields name = models.CharField(max_length=30) serial = models.CharField(max_length=30, unique=True, blank=True, null=True, default=None) mac_address = models.CharField(max_length=30, null=True, blank=True) purchased_date = models.DateField(null=True, blank=True) may_be_loaned = models.BooleanField(default=False, blank=True, null=True) notes = models.TextField(max_length=448, null=True, blank=True) ip = models.CharField(max_length=90, null=True, blank=True) created = models.DateTimeField(auto_now_add=True, editable=False) last_updated = models.DateTimeField(auto_now=True, editable=False) class Meta: ordering = ["name"] def __str__(self): return str(self.name) def get_absolute_url(self): return reverse("asset_app_asset_detail", args=(self.pk,)) def get_update_url(self): return reverse("asset_app_asset_update", args=(self.pk,)) class Asset_type(models.Model): # Fields name = models.CharField(max_length=30) last_updated = models.DateTimeField(auto_now=True, editable=False) created = models.DateTimeField(auto_now_add=True, editable=False) notes = models.TextField(max_length=448, null=True, blank=True) class Meta: ordering = ["name"] def __str__(self): return str(self.name) def get_absolute_url(self): return reverse("asset_app_asset_type_detail", args=(self.pk,)) def get_update_url(self): return reverse("asset_app_asset_type_update", args=(self.pk,)) views.py class Asset_typeDetailView(generic.DetailView): model = models.Asset_type form_class = forms.Asset_typeForm -
Direct assignment to the forward side of a many-to-many set is prohibited. Use Class.set() instead
