queryset average values of column
I´m trying to make an queryset with Django but I have no clue how to do that. The query that I want to do is: select format(avg(progress),1) as progreso from c_lp_view where user_id = 21 and c_id = 1; Now in Django my queryset looks like this: CLpView.objects.filter(user_id = user_id).filter(c_id__in=lRels).aggregate(avg_progress=Avg('progress')) Thanks for the help -

Many fields. Validate them so that errors should be next to problematic fields

How to return username instead of ID
Before calling this a repeat question please have a look at my code. I have a Blog Model and here is the Favourites part of it: class Fav(models.Model) : post = models.ForeignKey(Post, on_delete=models.CASCADE) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) class Meta: unique_together = ('post', 'user') def __str__(self) : return str(self.user.username) My serializer looks like this: class FavSerializer(serializers.ModelSerializer): class Meta: model = Fav fields = ['post', 'user'] I assumed because of the __str__ part, that this API will return the username but instead it returns only the user_id. How can I return the username? -
Django Display Multiple Values from Dependent Dropdown
I'm using Python 3.8 & Django 3.0 and need multiple values (volume & volume size) to go to a dependent dropdown. I've been able to populate the dependent dropdown with a single value (volume).

Django - how to create multiple select (on CreateView) to a foreign key on the related model?
I have those two models: Student class Student(models.Model): name = models.CharField(max_length=50, default='') class = models.ForeignKey(Class, related_name='students', on_delete=models.SET_NULL, blank=True, null=True) Class class Class(models.Model): code = models.CharField(primary_key=True,verbose_name='Code', max_length=50) When the user creates a new Class, I need them to be able to choose the students that it's going to be in the class.

What does JWT being stateless really means?
Hi and thanks in advance, I've successfully setup JWT authentication using django-rest-framework-simplejwt and React but I'm still very confused about the advantages and specifically database hits. I'm using simplejwt with ROTATE_REFRESH_TOKENS': True 'BLACKLIST_AFTER_ROTATION': True, when my access_token expire I ask for a new one through /api/token/refresh and it blacklist old tokens, I'm using axios interceptors to perform that automatically. But in my understanding the benefits of JWt is that they are stateless, meaning I don't have to hit the user database table everytime I want to make an a request that needs authentication permission. The problem is even with a simple view like this : class IsConnecteddAPI(APIView): permission_classes = [permissions.IsAuthenticated] def get(self, request, *args, **kwargs): data = "You seem to be connected" return Response(data, status=status.HTTP_200_OK) using django-silk I see that it still performs 1 query to my user table when I call it with a valid access token, is that normal ? If so why do we say that JWT are stateless ? I'm really confused. That's my axios code if needed : import axios from "axios"; const baseURL = "http://localhost:5000"; const axiosInstance = axios.create({ baseURL: baseURL, timeout: 5000, headers: { Authorization: localStorage.getItem("accesstoken") ? "JWT " + localStorage.getItem("accesstoken") : null, … -

Postgres data_type modification in Django
The web application I'm working on in Django ran into a bug when I attempted modifying the data type of a field(column). I got some advice to drop/delete the table which didn't end up very well. Now I'm stuck. I tried creating a new table manually but its still giving me the same error. I tried changing the name of the previous table from its models.py, but that didn't work either. The website is giving me this error, 'Server Error (500),' as it is in production mode and the debug is set to false. I've tried. 'python manage.py makemigrations,' but it says no changes. Also, 'python manage.py migrate,' but that gives an error. -

Python braincube-connector date slicing
I have been successful in obtaining data via the package. I am now attempting to retrieve data based on a desired date range. The methods provided with the braincube_connector pypi project description site do not work properly to my knowledge. The parse_date parameter does not seem to work. Setting the condition to true using parameters.set_parameter({"parse_date": True}) does not actually return dates when using .get_data(). There is a timestamp variable in the data set I am trying to obtain. To my knowledge I should then be able to use a filter with the “BETWEEN” keyword to retrieve the data in the desired date range. The timestamp data is of a “DATETIME” type according to .get_type(). When I parse a datetime element the following error appears: TypeError: Object of type datetime is not JSON serializable I then attempted to use the DjangoJSONEncoder to no avail and various other methods of parsing a start and end timestamp. -

does a user changing the title / slug cause an issue if i continue to get the correct post by pk?
Currently i have a django project where a user can ask a question and the title becomes the slug. MEaning the url is website/pk/slug To get to the url i use a basic DetailView which just uses the model. URLs path('question/<int:pk>/<str:slug>/', QuestionDetailView.as_view(), name='question-detail'), path('question/<int:pk>/<str:slug>/update/', QuestionUpdateView.as_view(), name='question-update'), View class QuestionDetailView(DetailView): model = Question When the user changes the title of the question, i do not update the slug but only the title. class QuestionUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Question form_class = QuestionForm def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def test_func(self): question = self.get_object() if self.request.user == question.author: return True return False This mean is the original url upon question creation was website/1245/How-do-i-blah i can still get to the question with any slug after website/1245/ i would think this might be a problem but i cannot see why, as google will index the slug and as i am looking up by pk if the title changes it should automatically return the right question. Why do i think this might cause problems in the future? And should i be looking up the question by pk and slug. -

Memcached not caching page if it's requested by artificial request. Django
I use memcached for caching a page for 1 hour. My settings are following: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', } } I use method decorator to cache the view. @method_decorator(cache_page(60 * 60), name='dispatch') I want to warm up cache every hour. I do it by emulating request to the view. login_url = LOGIN_URL target_url = TARGET_URL request = requests.session() response = request.get(login_url) token = response.cookies['csrftoken'] data={'username': username, 'password': password,'csrfmiddlewaretoken':token} response = request.post(login_url, data=data) response = request.get(target_url) However, unlike requesting the view myself (by hands) it doesn't work.
