Django Rest Framework transforming my APIView into a ModelViewSet
I have the following model, class Schema(models.Model): week = models.PositiveIntegerField(validators=[MinValueValidator(1), MaxValueValidator(53)]) users = models.ManyToManyField(MyUser, related_name="users") class Meta: ordering = ('week',) The model holds a week number and list of users related to that week number. I have then created an APIView where the GET request fetches all the Schemas (my model), and the POST request does the following, if the week number is not in the database then it simply creates a row in the database for the given week number and the given users. If the week number is already present in the database then I simply overwrite the users related to that week number with the newly given users, the view looks like this, class SchemaView(APIView): permission_classes = (SchemaPermissions,) def get(self, request): schemas = Schema.objects.all() serializer = SchemaSerializer(schemas, many=True) return Response(serializer.data) def post(self, request): data = request.data serializer = SchemaSerializer(data=data) if serializer.is_valid(): input_data = serializer.validated_data week = input_data.get('week') user_ids = input_data.get('user_ids') if Schema.objects.filter(week = week).count() > 0: schema = Schema.objects.get(week = week).first() else: schema = Schema.objects.create(week = week) schema.users.set(user_ids) schema.save() return Response(SchemaSerializer(schema).data, status=status.HTTP_200_OK) else: return Response(status = status.HTTP_400_BAD_REQUEST) Now this works as expected, however now comes my problem. This only works for a single "Schema" (my model) on … -

Cannot login to django admin panel after changing password
I hope you are fine. I have a superuser in django admin and the problem is that when this superuser changes his password, he will be redirected to the django admin login page and when the superuser enters correct username and password in the admin login page, it gives an error that is “Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive.”, but I am sure that both of the username and password fields are filled correctly; I will thank if anyone help me to solve this problem. Thanks. -

space in url Django
I am creating a search bar on my site, everything is fine if I pass the names without spaces, being that I pass the word of the search bar directly in the url, as you can imagine the problem arises when the user enters words with space. I also convert the url into utf-8, but I think django does it automatically because even without the conversion in the url if you pass the space it appears at its post% 20, I wanted to clarify that the problem persists if you enter characters like:! ?can someone help me?

Ajax call run by form submission and will pass data to a separate views.py template
I am building a web application using Django. I have a search function on my index page. When a user submits the form an AJAX call should be executed. This AJAX call should take all the needed data from the form and pass it over to a completely separate views.py template that will make API GET requests using that data and build a new page using that separate template. As of right now it is not loading the separate views.py template, I am unsure if I am passing the data correctly however I do see /searchresults?searchType=data1&amp;executeLocation=data2 in my console because my AJAX call is returning on success currently. It is safe to assume that I have all the data needed in the data1 and data2 variables, I just need help redirecting to the new page and passing the data along with the redirect. My code: urls.py # The home page path('', views.index, name='home'), # Search results page path('searchresults', views.search_results, name='searchresults'), AJAX function getSearchResults(searchType,executeLocation,csrf_token) { $.ajax( { type: $(this).attr('method'), url: "searchresults", //The URL you defined in urls.py data : { searchType: searchType, executeLocation: executeLocation, csrfmiddlewaretoken: csrf_token }, dataType: 'text', success: function(response) // currently executes success (but not correct outcome) { console.log(response); …
