How can I store my static files to some other github repo?

Django IntegrityError: Key is not present in table (but query of key works)
I have a strange problem with Django tests. The issue only occurs when I ran the test command python3 manage.py test. Background information: I have a subscription model with a custom save method which sends info mails, create bills and lessons and more. After the subscription is saved into the database with the super().save(using=using, *args, **kwargs) command, the method self.create_lessons() get's called and this method causes the IntegrityError on creation of the lessons, saying that the subscription doesn't exists in the table. To check if the subscription really doesn't exists in the subscription table I have added a query s = Subscription.objects.get(id=self.id) and printed it to the console print(s). The query and the print command are working fine, but i still get the integrity error. Whats really confusing, at least for me, is that the error only occurs when I run the python3 manage.py test command. When I run the webserver and create subscriptions with the admin panel or the shell everything is running like it should. Even stranger is that the error disappears for a while (2-3 successful executions of the test command) when I make a change to the code which doesn't really matter. For example a comment … -

Django / Ubuntu 20 - How change to a previous version of GDAL
first of all, thanks for your help. I'm new to django, and I'm developing a site where you have to enter coordinates in some forms and then they should be editable. So far, so good, I haven't had any problem creating that, however, as I read, in some of the more recent versions, the order in which GDAL reads the coordinates was changed, so the positions appear inverted when reading data from geospatial databases. In other words, the coordinates are entered right (from PgAdmin they look right) but are read wrong when you load them into a leaflet map with Django. I asked about how to correct this (Link to my previous question) but got no answer and haven't been able to solve it myself. Therefore, the only thing I can think of is to try with previous versions of GDAL, however, I'm not quite sure how to do it. I followed the next steps to install it: pip3 install gdal sudo apt-get install gdal-bin libgdal-dev sudo apt-get install python3-gdal Thanks in advance -

Django manager annotate first element of m2m as fk
Let's say I have these models. class AdventureWaypoint(models.Model): adventure = models.ForeignKey("Adventure", on_delete=models.CASCADE) waypoint = models.ForeignKey("Waypoint", on_delete=models.CASCADE) created_timestamp = models.DateTimeField(auto_now_add=True) class Waypoint(models.Model): name = models.CharField(max_length=255) class Adventure(models.Model): waypoints = models.ManyToManyField("Waypoint", through='AdventureWaypoint', related_name='waypoints') objects = AdventureManager() How could I write a manager that annotates first_waypoint to every queryset?

Why does PyCharm show an empty Django Model Dependency Diagram
The PyCharm Pro IDE has a convenient feature called a Django Model Dependency Diagram, which visualizes the relations between your Django models. However, every so often, this diagram turns up blank, or does not work at all, without any error messages (except in the logs). There's a related issue here: https://youtrack.jetbrains.com/issue/PY-39831 What could possibly cause the Django Model Dependency Diagram to turn up empty? -
Delete firebase token not accepting token in parameters
I created an endpoint on my API to DELETE a firebase token. The token is given in parameters. This is my test unit, that works fine: @patch("pyfcm.FCMNotification.clean_registration_ids") def test_delete_firebase_token(self, fcm_mock): fcm_mock.return_value = "thetokengeneratedbyfirebase" token = "dummytoken" # create token FirebaseConnectionFactory(user=self.author, token=token) # delete token url = reverse("user-firebase", kwargs={"user_pk": self.author.pk}) response = self.client.delete(url, data={"token": token,}, format="json",) self.assertEqual(response.status_code, status.HTTP_200_OK) self.assertIsNone( FirebaseConnection.objects.filter( token=token, user_id=self.author.pk ).first() ) This is my view: def delete(self, request, user_pk): """ Delete Firebase token. """ user = request.user if int(user.pk) != int(user_pk): raise PermissionDenied serializer_class = self.get_serializer_class() serializer = serializer_class(data=request.data, context={"user_pk": user_pk}) serializer.is_valid(raise_exception=True) token = serializer.validated_data.get("token") FirebaseConnection.objects.filter(token=token, user_id=user_pk).delete() return Response({}, status=status.HTTP_200_OK) serializer: class FirebaseDeleteSerializer(serializers.ModelSerializer): class Meta: model = FirebaseConnection fields = ("token",) # noinspection PyMethodMayBeStatic def validate_token(self, token): user_pk = self.context["user_pk"] validate_token_helper(token) if not FirebaseConnection.objects.filter(token=token, user_id=user_pk).exists(): raise serializers.ValidationError( "You don't have permission to perform this action." ) return token So when I try this endpoint, I can't give the token in parameters. It gives an error that it's not valid. I guess that's because the ':' symbol in string? But I'm not sure how to solve it properly. Validation says I'm not sending token at all. -
Wagtail: How to remove summary items on the admin homepgae
I am trying to remove/customize the summary items on the admin homepage with the recommended hook construct_homepage_summary_items. Add or remove items from the ‘site summary’ bar on the admin homepage (which shows the number of pages and other object that exist on the site). I manage to add my own items but struggle to remove all of the default items. @hooks.register("construct_homepage_summary_items") def add_my_summary_items(request, items): items.append(MySummaryItem(request)) items.pop(0) items only includes my custom items and wagtail.admin.site_summary.PagesSummaryItem but not those for images and documents. Removing items with pop doesn't seem to be as elegant as it could be either. I hoped for some way along the lines of the construct_main_menu hook: menu_items[:] = [item for item in menu_items if item.name != 'explorer'] But I could not find a name identifier or an equivalent. How would I go on about it? -

Django File update not saving to folder
I am trying to update a form in which there is a input type file. But while saving the changes, name of the file is updated to database (MySQL) but not storing in folder. While uploading for the first time it works perfectly. upload_to option of FileField in modals is working fine and file is uploading to that upload_to path. But When I am trying to update the file, only file name name is updating to database. I can't share complete code due to non disclosure agreement with client. Few other fields are also there in form and everything is updating in database correctly. Only file is not uploading to specified path. Any help is appreciated. I tried many solutions available but none of them are working. Models.py Class Task(models.Model): attached_resources = models.FileField(upload_to='project/images/task/',default='') edit-task.html <form method="post" action="/app/task-detail/" enctype="multipart/form-data"> {% csrf_token %} <input name="task_file" type="file"> </form> views.py def task_detail(request): if request.method == 'POST': task_id = request.POST['task_id'] task_file = request.FILES['task_file'] task_to_edit = Task.objects.filter(id=task_id).update(attached_resources=task_file)
