Django - on delete -> unhashable type: 'Highscore'
I made an simple webpage with Django. It stores highscores. I can't delete an highscore because it throws an exception. The exception says unhashable type: 'Highscore' (I don't think it makes an difference but i also got an foreign key but that shouldn't be the problem) So i already flushed the DB (Database) and reset it up (makemigrations, migrate, new inputs) but that doesn't work. I also can't delete it over the adminpage (127.0.0.1:8000/admin). def highscore_delete(request, h_id): try: h = Highscore.objects.get(id=h_id) h.delete() except Highscore.DoesNotExist: raise Http404('Highscore not found') except Exception as ex: return HttpResponseBadRequest(ex) return redirect('highscore_index_route') It throws the exception at h.delete(). More information under under: https://pastebin.com/9kaF4NBy (i will post noncritical code there) Of course the entry doesn't get deleted, even though this method work multiple times already. (There is no syntax error) -
Django url is not picking the updated django view
Use Case : When ever i am tryng to access my url e.g.http://127.0.0.1:8000/dashboard/ it always picks the old code from dashbaord/views.py Old view : def dashboard(request): context = {'data':[29,25,25]} template='dashboard.html' return render(request,template,context) Updated view def dashboard(request): abc='pankaj' context = {'data':[15,20,10]} template='dashboard.html' return render(request,template,context) When i am loading this page, it gives some error and shows the old view code not the latest one.

In django, how can I get detailed error information in ajax?
I'm learning web programming with Django. Currently I'm trying to build a webpage that users can update their user profile (such as e-mail, nickname). I'm using ajax to process this data. But I just came up with a question that how can I get detailed ajax error information? For example, an user wants to update his nickname or e-mail, but the nickname or e-mail he posts is already existing in the database. In ajax, I use error:function (XMLHttpRequest, textStatus, errorThrown) {} to get the error information. But I just get something like "500 Internal server error". However, in the browser console I can see whether "nickname" or "e-mail" is duplicated. So I wonder how I can get to know which one is duplicated? My view.py is: @login_required def edit_usr_profile(request): user = request.user objs = UserProfile.objects.filter(usr=user) usr_objs = UserProfile.objects.get(usr=user) if request.method == 'POST': if request.is_ajax(): usr_objs.nickname = request.POST.get('nickname') usr_objs.email = request.POST.get('email') usr_objs.save() return render(request, 'account/edit_profile.html', {'objs':objs}) my ajax code is: $.ajax({ type:'POST', url:'./', data:{ async: false, nickname:usr_nickname, email:usr_email, csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val() }, success:function () { alert('New profile saved!') //window.location.reload() }, error:function (XMLHttpRequest, textStatus, errorThrown) { alert('Error! Please check your entry and try again!') } }) I'll be very appreciated if you can help … -

How to add child instance foreign key IDs as a serializer list field idiomatically?
I've got a many-to-many model like Request ← RequestItem → Item, and I want the response from the Request API endpoint to include a list of Item IDs. I've got a working serializer method like this: def to_representation(self, instance: Request) -> typing.Dict[str, Any]: representation: Dict = super().to_representation(instance) representation["items"] = [ item_id for item_id in instance.requestitems_set.values_list("item_id", flat=True) ] return representation As you can see, this is horrible.

When do inherited django models not set abstract = False by default?
I've read https://docs.djangoproject.com/en/2.2/topics/db/models/#meta-inheritance and see that Django does make one adjustment to the Meta class of an abstract base class: before installing the Meta attribute, it sets abstract=False. This means that children of abstract base classes don’t automatically become abstract classes themselves. Of course, you can make an abstract base class that inherits from another abstract base class. You just need to remember to explicitly set abstract=True each time. I'm running Django 2.2 and am finding that models inherited from abstract models are not defaulting abstract to False unless implicitly set. Sample code is attached. class Foo(models.Model): class Meta: app_label = 'foo' abstract = True class Bar(Foo): name = models.CharField(max_length=128) code = models.CharField(max_length=32, unique=True) url = models.URLField(max_length=256) Running makemigrations returns No changes detected. Adding class Meta: abstract = False to Bar and running makemigrations works. Known problem with 2.2 or user error? Thanks. -
