Django Model not being updated after calling save() method
Im Using django signals to update a foreign key object of a model . @receiver(sender=PointItem, signal=post_save) def PointItemSaved(instance, sender, **kwargs): try: print(f"before save {user.points}") user = User.objects.get(id=instance.user.id) user.points += 100 user.save() print(f"after save {user.points}") except Exception as e: print(f"there is a problem {e}") according to logs , everything is correct . before & after values are correct . but when i check it on admin page it does not changed ! -
During handling of the above exception (badly formed hexadecimal UUID string), another exception occurred:
I have a checkbox list - user check which items to update - <th scope="row"><input type="checkbox" name="document_detail" value="{{ result.id }}" id="result_check"/>{{ result.id }} This is handled in view by: document_request = request.POST['document_detail'] logging.info(document_request) approval_items = [] for document in document_request: logging.info(document) logging.info gives the correct UUID field e.g. 91da274b-208f-4d65-9e5f-d5cbf2860961 after the loop is initiated the value change to simply "9" or the first character of the UUID. e.g. logging.info give "9" hence the correct error of badly formed UUID Is there a correct method of handling this type of item that I'm missing? -

Change URL when link is clicked in iFrame, when the links in question would be created by user input?
From what I can understand, the URLs of site do not change during navigation if the element with the href/src is within an iframe. And there is a way to override this by getting the ID of every single link element that would exist in the iframe and then set the src manually on each, such as in the response to this question Change URL in an iframe using javascript However the links I want to reflect in the URL are to pages created and added to the site by users, and I cannot know in advance what these URLs will be called, so cannot manually link to them in advance. Is there a workaround for this? And if so, is it really worth the effort and possible messiness? The iframe in question is part of a 3rd party library that I have no control over (django-fobi) -

Dango admin throws empty exception when calling __str__ method
I'm developping a web app with Django (2.2). I have the following Profile model extending the built-in User model trough an One-to-one relationship. class Profile(models.Model): class Meta: ordering = ['user__last_name'] txt = models.CharField("TXT", max_length=5, null=True, blank=True, unique=True) user = models.OneToOneField(User, on_delete=models.PROTECT) colleague = models.ForeignKey('self', on_delete=models.PROTECT, null=True, blank=True) def __str__(self): """ Display of User with its full name""" return "%s %s" % (self.user.last_name.upper(), self.user.first_name.capitalize()) The __str__ method works well in the Admin list display view or in a Django shell. However, an exception is thrown when I try to access to the admin form, pointing to the __str__ method but without any detail. When the __str__ method is removed the form is displayed correctly.

Django deployment with Daphne
I want to deploy my Django app (Rest API + React on frontend) on AWS. I use nginx, gunicorn (for http handling) and daphne (for async websockets - Im using django channels for chat application). I was following THIS tutorial. It looks like I configured well nginx and gunicorn (page is normally loading, I can handle sync request to rest API) but I guess there are some problems with daphne and/or asgi. I use systemctl services for server. All 3 (nginx, gunicorn, daphne) statuses show 'active'. Everything works fine on my development server on local. On deployment server when I enter website, I see in console Firefox can’t establish a connection to the server at ws://PATH_TO_WEBSOCKET Is Daphne connected well with Nginx?

One place to monitor modifications of django model

Deleting database objects in django - How do I correctly make a delete function?
I'm building my first solo django project and one of the stumbling blocks I've run into is creating a "delete function" so I can delete objects in the database. I've been looking at various tutorials for this but I'm getting slightly confused along the way. I'd really appreciate any advice on how to do this correctly in django. Here's what I've been working with so far. I have a model called "Myteam" which looks like this... class Myteam(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE, null=True) QB = models.CharField(max_length=80, null=True) QBscore = models.IntegerField(null=True) RB1 = models.CharField(max_length=80, null=True) RB1score = models.IntegerField(null=True) RB2 = models.CharField(max_length=80, null=True) RB2score = models.IntegerField(null=True) WR = models.CharField(max_length=80, null=True) WR1score = models.IntegerField(null=True) WR2 = models.CharField(max_length=80, null=True) WR2score = models.IntegerField(null=True) TE = models.CharField(max_length=80, null=True) TEscore = models.IntegerField(null=True) D = models.CharField(max_length=80, null=True) Dscore = models.IntegerField(null=True) K = models.CharField(max_length=80, null=True) Kscore = models.IntegerField(null=True) In my views.py, yesterday, I tried this out... def delete_player(request, pk): player = Myteam.objects.get(pk=id) if request.method == 'POST': player.delete() return HttpResponseRedirect(reverse("index")) return render(request, 'game/index.html') Here's my urls.py path('delete_player/<str:pk>', views.delete_player, name="delete_player") For the html, I was initially trying to have a button link to the delete_player function, but so many of the tutorials I've been looking at use a form with a … -

I have a simple and possible quite dumb question on Pytest.
