Django exception Issue [closed]
So I have a view which creates a form, saves info from the form and accepts a payment string from payment provider. Here is the code: if request.method == 'GET': #Step 1: create form elif request.method == 'POST': try: #Step 2: get form with inputs if form.is_valid(): #Step 2.1: save info except: # there is no form. #Step 3: I accept the query set from payment provider with transaction confirmation In the last step nothing happens. I've spent like 3 yours, but still can't fix the issue. -
How to do user authentication in django when using windows (crypt module is not supported on windows)
I was trying to register user in django using User model from 'django.contrib.auth.models', but when encrypting password, it shows 'The crypt module is not supported on Windows'. Also I tried importing from passlib.hash the pbkdf2_sha256 to encrypt the data. serializers.py class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('id', 'username', 'email') class RegisterSerializer(serializers.ModelSerializer): class Meta: model = User fields = ['id', 'username', 'email', 'password'] extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): encryptedpass = pbkdf2_sha256.encrypt(validated_data['password'], rounds=12000, salt_size=32) user = User.objects.create_user(username=validated_data['username'], email=validated_data['email'], password=encryptedpass) return user views.py class RegisterAPI(generics.GenericAPIView): serializer_class = RegisterSerializer def post(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.save() return Response({ "user": UserSerializer(user, context=self.get_serializer_context()).data, "token": AuthToken.objects.create(user)[1] }) class LoginAPI(KnoxLoginView): permission_classes = (permissions.AllowAny,) def post(self, request, format=None): encryptedpass = pbkdf2_sha256.encrypt(request.data['password'], rounds=12000, salt_size=32) mydata = {'username':request.data['username'], 'password':encryptedpass} serializer = AuthTokenSerializer(data=mydata) serializer.is_valid(raise_exception=True) user = serializer.validated_data['user'] login(request, user) return super(LoginAPI, self).post(request, format=None) # Get User API class UserAPI(generics.RetrieveAPIView): permission_classes = [permissions.IsAuthenticated,] serializer_class = UserSerializer def get_object(self): return self.request.user But during authentication in login part, it does not match the credentials, maybe because the function checking for validity uses some other encryption method.

Django: Filter data between to dates | DatetimeField received a naive datetime
I simply want to filter my records between two dates. Let's say there is a record table Measurements that has the property timestamp: class Measurements(models.Model): id = models.BigAutoField(primary_key=True) timestamp = models.DateTimeField() When I checked the timestamp of the last record Measurements.objects.last().timestamp it returns: datetime.datetime(2020, 10, 13, 6, 29, 48, 90138, tzinfo=<UTC>) Now I want to filter the data between to dates from_date and to_date. According to previous questions about this issue, I used make_aware. For testing I used count to get the amount of entries. from .models import * from datetime import datetime from django.utils.timezone import make_aware def get_measurements(request): from_date = make_aware(datetime(2020, 10, 12, 15, 30, 0, 0)) to_date = make_aware(datetime(2020, 10, 12, 16, 0, 0, 0)) print(from_date) print(to_date) measurements = DriveMeasurements.objects.filter( plc_timestamp__range=["2020-01-01", "2020-01-31"]) print(measurements.count()) When printing the two dates in my shell, it returns: datetime.datetime(2020, 10, 12, 15, 30, tzinfo=<UTC>) datetime.datetime(2020, 10, 12, 16, 0, tzinfo=<UTC>) When I run the function above, Django fires the following message: RuntimeWarning: DateTimeField Measurements.timestamp received a naive datetime (2020-01-31 00:00:00) while time zone support is active. warnings.warn("DateTimeField %s received a naive datetime (%s)" The print statement print(measurements.count()) prints 0 but there are ~ 18000 records in the database. So why is the filter … -

Django Custom Manager to dynamically filter archived objects
Suppose I have a model: class Car(models.Model): name = models.CharField(max_length=50) is_active = models.BooleanField(default=True) When I query on Car, I always want to return the objects satisfying, is_active=True. For this, searching on StackOverFlow, I get that my best bet is to use ModelManager, like this: class CarManager(models.ModelManager): def get_queryset(self): return super().get_queryset().filter(is_active=True) And, use this Manager in my model. class Car(models.Model): name = models.CharField(max_length=50) is_active = models.BooleanField(default=True) objects = CarManager() Using this solution always returns active Car queryset. But, sometimes I want to return inactive Car queryset as well, and I don't want to write another ModelManager. To elaborate, When I run, Car.objects.all() or, Car.objects.filter(name__contains='Car') or, Car.objects.filter(is_active=True) I only want active Car queryset. When I run, Car.objects.filter(is_active=False) I want to have inactive Car queryset. And, I want to achieve this using single ModelManager and default methods (get, filter, all, etc). Why I want this is because, it has been used in many places already. So, is there any way to achieve this? Any suggestions or insights are heartily welcome. Thanks for your help in advance. -
Many views in one template? [django]

Django: How can I display the original filename of an Uploaded file in HTML?
I want to show the exact filename of a user-uploaded file in a page, but I haven't found a sort of out-of-the-box way to do it, and I'd like to know if it exists or what could be a better way to do it. 1.- I can't split a string with Django's template language. I found there is a truncatechars filter, but that won't work for me because filenames have different lengths and, if they get truncated, I get an ellipsis at the end. 2.- In the only answer to this question, the user says FileField objects have a filename attribute. However, there is no filename attribute defined here or here and, actually, if I do the same ModelObject.field_name.filename, I get AttributeError: 'FieldFile' object has no attribute 'filename'. Possible solutions I have found: I see I can define a custom template filter that can do string.split('/')[-1], but I'm not sure if that's kind of an overkill for this. Also, note that, if this method is used, I could end up showing the user a different filename in the case in which they uploaded a file with the same name of an existing file in their user directory inside the media … -

Get scheduled events for a specific interval
I have a series of events, set by their frequency of occurrence, for example, weekly (like every Tuesday), monthly (every second number), etc. There is a start date for a sequence of events and an end date can be specified or omitted. eg: event = Event ( name = 'go to the office', startday = '13 .10.2020', schedule = Schedule (type ='weekly', details = {'day':' Tuesday'}) ) it is just an example interface, which can be adjusted if required by the tool The task itself is that I need to make a query with a certain start-end time interval and get all the events in the interval. Therefore, the question is, are there any libraries that solve such problems, or I have to reinvent the wheel? I have to do it in Django based project, so if Django based solution is more convenient. -
CBV using django-filter with django-table2

Django: filter first items, based on ForeignKey
Let's say I have this models (mariaDB): class MediaSeries(models.Model): name = models.CharField(max_length=200) description = models.TextField(blank=True) class MediaFiles(models.Model): entryNr = models.IntegerField(default=0, help_text="number of episode") name = models.CharField(max_length=300) serie = models.ForeignKey(MediaSeries, null=True, on_delete=models.SET_DEFAULT) MediaFiles can be a single entry, or a part of a series. When it is a part of a series, it will have an unique entryNr. The entryNr can start with any number, not only from 1. I need now a filter method to filter all Mediafiles entries, what is part of an series, but only the first entry.

Django admin list_filter: RelatedFieldListFilter based on user
The question is similar to Django "list_filter" based on the admin queryset. I need to use list_filter based on current user. But in my case the field span relations using the __ lookup.

My approach resulted in the next code: def custom_titled_filter(title): class Wrapper(admin.FieldListFilter): def __new__(cls, field, request, *args, **kwargs): instance = admin.FieldListFilter.create(field, request, *args, **kwargs) instance.title = title rel_model = field.remote_field.model qs = rel_model._default_manager.all() if not request.user.is_superuser: qs = qs.filter(user=request.user) choice_func = operator.attrgetter( field.remote_field.get_related_field().attname if hasattr(field.remote_field, 'get_related_field') else 'pk' ) instance.lookup_choices = [ (choice_func(x), str(x)) for x in qs ] return instance return Wrapper Is there any better approach with current version of Django? -

How to reuse a big, expensive-to-load dictionary in Python?
I've got a 1 GB dictionary that takes a while to load into memory. But once the loading process is complete, running lookups in that dictionary is pretty fast. How do I best reuse that loaded dictionary from various Python scripts that may get spawned in response to network requests?
