Page keeps reloading after adding a new channels consumer and route
hope you all are doing well. I have been working on creating an asynchronous notification system, I already have a chat system but it is directed only towards the /inbox/ url. The problem that I'm facing is when I add a new consumer and access the home page the home page keeps reloading again and again and the terminal doesn't show any error. this is what my code looks like: Consumers.py async def websocket_connect(self,event): print("connected",event) await self.accept() async def websocket_receive(self,event): print("received",event) async def websocket_disconnect(self,event): print(event,"closed") class ChatConsumer(AsyncWebsocketConsumer): async def websocket_connect(self,event): print("connected") self.channel_layer = channels.layers.get_channel_layer() ..... await self.accept() async def websocket_receive(self,event): print("received2",event) ..... async def websocket_disconnect(self,event): print("disconnected",event) Routing.py from . import consumers from django.urls import re_path,path websocket_urlpatterns = [re_path(r"^a/inbox/(?P<username>[\w.@+-]+)", consumers.ChatConsumer.as_asgi()), re_path(r"a/(?P<username>[\w.@+-]+)",consumers.NotificationConsumer.as_asgi()), ] I'm trying to create a notifications websocket, any leads or any correction would be much appreciated. -

Displaying checked and unchecked ManyToMany choices in DetailView
I'm looking for an elegant way to show all available items (not just checked ones) in a Django DetailView, while stylizing the checked ones. Given following model: class Topping(models.Model): title = models.CharField(max_length=200) class Pizza(models.Model): topping = models.ManyToManyField(Topping, blank=True, null=True) I'm rendering toppings in my form with a CheckboxSelectMultiple (=rendered as multiple checkboxes), like: toppings = forms.ModelMultipleChoiceField( required=False, queryset=Toppings.objects.all(), widget=forms.CheckboxSelectMultiple, ) It is also relevant which toppings were not selected, hence I'd like to render something in my DetailView like the following (showing a checked checkbox when selected; showing an empty checkbox and light gray text when not selected, respecting the same order as seen in the form, i.e. alphabetically in this example): Chosen pizza toppings: ☑ Bluecheese ☐ Green peppers ☐ Onions ☑ Red peppers I currently go through the toppings as follows, but this only shows the selected ones: {% for option in object.toppings.all %}☑ {{ option }}<br />{% endfor %} I have a whole bunch of different ManyToManyFields on my main model. -

Unable to save multiple value with Select2 in Django
I try to post multiple value selected from ajax response. But when I specify name of 'Select' tag as array - <select name="item_ids[]" nothing is saved.

Django model with Charfield Count and Zero values
I have a Django database model that has some attributes, one of them is a Charfield 'category' with Choices. I now want to annotate a queryset of this model with the count of the rows of each category. The thing is, the way i know to do it, only categories present in the queryset are getting counted, but i want a queryset with all categories annotated with the count (0 if no rows with this category). This is what im doing at the moment: Model.objects.all().values('category').annotate(total=Count('category')) Is there a way to display all categories, including such with count 0? -
How to close popup in Django Admin
I am using Python 3.7.10 with Django 3.1.6, and I have used the following code to create an admin popup that will be triggered when clicking on the "edit_link": class EditLinkWidget(forms.URLInput): def render(self, name, value, attrs, renderer): super().render(name, value, attrs, renderer) if not value: return '' return mark_safe(f'<a class="related-widget-wrapper-link change-related" href="{value}?_to_field=id&_popup=1" '\ 'data-href-template="{}?_to_field=id&_popup=1">Edit</a>').format( re.sub("(\d+)", "__fk__", value)) class PageForm(TranslatableModelForm): edit_link = forms.CharField(widget=EditLinkWidget, required=False, disabled=True) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.instance.pk: self.fields['edit_link'].initial = f'/admin/cms/car/{self.instance.car_id}/change/') class Meta: model = User fields = ('edit_link',) It works great, but the problem is that the popup doesn't close automatically when I click on the Save button, throwing the following javascript error: Does somebody know how can I fix it so the popup can be closed automatically? I guess it should communicate with the parent admin page somehow? -
How to use Base64FileField together with the FileField?
I am using Django rest and initially, I used form-data to upload images to Django. My model has a FileField and it worked well. Right now, I need to handle JSON uploads also. I integrated this Base64FileField from the drf-extra-fields, added it to the serializer, but now my form-data request fails with the following error: "innitial_file_path": [ "Invalid type. This is not an base64 string: <class 'django.core.files.uploadedfile.InMemoryUploadedFile'>" ] How can I make it work for both the form-data and JSON request body? I suppose I still need to keep FileField in my model, but somehow convert base64 to the JSON. Also, should I create multiple serializers? Right now I have multiple nested serializes, so it would be difficult to use by creating multiple. I would then need to get the content-type in the create method of the serializer and depending on that use different serializer. How can I get that? -

Better way to setup PWA for a Django project

Photo upload: direct s3 upload vs via Django Imagefield and custom storage
My requirement: Get user to upload profile photo. Make sure that the file that is uploaded is really an Image. Image size cannot be more than 2MB. My options: Directly upload image to s3 using presigned url. In this case I don't have to worry about server resources running out when traffic load increases. But I would not be able to determine for sure if the file is an image. Just checking the extension is not enough to determine if the file is an image. I can upload it to s3 via django app using ImageField and custom s3 storage. ImageField uses pillow to make sure if the uploaded file is really an image. But I have to worry about server resources running out when traffic load increases. Increasing server resources is not an option. My questions: For direct upload how can I make sure if the file being uploaded is really an image? For image upload via django, how to mitigate or optimize the resource running out problem? -
Django-import-export problem importing foreignkey field

Can you use a class object as property in Django?
I have three models in my Django application - simplified for demonstration. The first one is Base. The second one is Bill and has foreign key "base" to Base model. The third one is Point, and has a foreign key to Bill. class Base(models.Model): type = models.CharField() desc = models.IntegerField() class Bill(models.Model): base = models.ForeignKey("Base", related_name="bills") total_value = models.DecimalField() class Point(models.Model): bill = models.ForeignKey("Bill", related_name="points) value = models.DecimalField() My goal is to have a property for Base called def bill(self), that would sum up all "bill" objects fields and returned a bill-like instance. I would like to get a base object: my_base = Base.objects.get() bill = Base.bill <-- I can figure this out with @property points = bill.points <-- this does not work through @property function. My current solution is like this, to get the first part working: class Base(): ... @property def bill(self): sums = self.bills.aggregate(total_value=Sum('total_value')) return Bill(**sums) The second part, that would sum up bill-related-points and return them in a my_base.bill.points, does not work.
