How to login custom user in django? (UNIQUE)
I want to login custom user, but it returns an error {'username': [ValidationError(['A user with that username already exists.'])]} . I have a model of Worker which inherits from User model, but also has some unique fields. models.py class Worker(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) fullname = models.CharField(max_length=150) branch = models.ForeignKey(Branch, on_delete=models.SET_NULL, null=True) position = models.CharField(max_length=200) manager = models.BooleanField(default=False) def __str__(self): return self.fullname views.py def loginUser(request): form = UserForm() if request.method == 'POST': form = UserForm(request.POST) fullname = request.POST.get('fullname') if form.is_valid(): username = form.cleaned_data.get('username') password = form.cleaned_data.get('password1') try: user = User.objects.get(username=username) except: print('User does not exist') user = authenticate(request, username=username, password=password) if user is not None: login(request, user) try: worker = Worker.objects.get(user=user, fullname=fullname) if worker.manager == False: return redirect('main') else: return redirect('manager-main') except: print('No such worker') form = UserForm() return render(request, 'supply/login.html', {'form':form}) else: print('Username or password does not exist') else: print(form.errors.as_data()) return render(request, 'supply/login.html', {'form':form}) So, I'm trying to login user, and then trying to get worker using user. After that, I check if the worker is manager. If he is, I redirect him to a page for managers. If he is not, I redirect him to his page. But if there is no such worker, I render login page … -

Reverse Serializing Many to Many Relations Causes RecursionError
Following on from this answer, I've attempted to reverse serialize objects from a many to many relationship. Using a serializer method field, I've tried to populate the people that have a person type however this is causing a RecursionError from django. I can see the issue, PersonA has PersonTypeA who has PersonA etc. but I'm not sure how to 'flatten' the returned people to one level. How can I overcome the recursion error?

Celery task not executing in Django project with Redis broker

How to display images in webpage in django with multiple apps
I currently have 2 applications. When I first made the first app it was displaying the images correctly. I would upload the images in the admin console then the image would be displayed in the webpage.

Django post_save signal, executing chained tasks
When I save a model I want to create some folders, then download a few things to those folders. Folders need to be created for the downloads, obviously, downloads can happen in parallel.

How can I chain tasks so they're executed in order without worrying about this? The functions return nothing. So I guess right now I end up with something like download_game.s(instance.id, instance.download_link, None) -
How to encrypt and decrypt access passwords in Django?
My Django application needs a table to store credentials of different users to access external databases that store their information. There are security and technical reasons not to use the same database that Django uses. But during storage, I would like to encrypt the passwords before inserting to the persistance, and later a way to decrypt them in order to make use of them. My first approach was to use make_password function, but I couldn't find a way to decrypt back the passwords. Right now I'm testing django signals with a pre_save script that encrypts the password using cryptographi.fernet algorithm. And later, this is decrypted inside the view execution. For encryption and decryption, I'm saving the key in settings file (loaded from environment). I would like to know if this is secure enough procedure to manage credentials to critical information of my users. Also if there is any way to get the password back when using make_password function. -
Django inbuilt Auth not logging me in despite successfully registering the user

I suspect the issue is with the validator... views.py class FollowViewSet( mixins.CreateModelMixin, mixins.ListModelMixin, viewsets.GenericViewSet): serializer_class = FollowSerializer permission_classes = (IsAuthenticated,) filter_backends = (filters.SearchFilter,) search_fields = ('following__username',) def get_queryset(self): return self.request.user.follows_user.all() def perform_create(self, serializer): serializer.save(user=self.request.user) serializers.py class FollowSerializer(serializers.ModelSerializer): user = serializers.SlugRelatedField(read_only=True, slug_field='username') following = serializers.SlugRelatedField( queryset=User.objects.all(), slug_field='username' ) class Meta: fields = ('user', 'following') model = Follow validators = [ UniqueTogetherValidator( queryset=Follow.objects.all(), fields=['user', 'following'] ) ] def validate(self, data): user = self.context['request'].user if user.username == data['following']: raise serializers.ValidationError('Нельзя подписаться на себя!') return data models.py class Follow(models.Model): user = models.ForeignKey( User, on_delete=models.CASCADE, related_name='follows_user', verbose_name='Подписавшийся пользователь') following = models.ForeignKey( User, on_delete=models.CASCADE, related_name='follows', blank=False, verbose_name='Пользователь, на которого подписаны') class Meta: verbose_name = 'Подписка' verbose_name_plural = 'Подписки' unique_together = ["user", "following"] def __str__(self): return f'{self.user.username} отслеживает {self.following.username}' With a GET request, all subscriptions should be displayed in the form: [ { "user": "string", "following": "string" } ] For a POST request with a request body like: { "following":"admin" } a Follow object should be created and output as a … -
How do I get around ModuleNotFoundError: No module named 'dot env
I am doing the official django tutorial polls app on part 5 which is about testing in django. As a part of the instructions I am supposed to go into my models.py file and run the python manage.py shell command to activate a shell terminal. From there I am supposed to run a series of commands to import things for my test. Link to material: https://docs.djangoproject.com/en/4.2/intro/tutorial05/ The commands I need to run are: >>> import datetime >>> from django.utils import timezone >>> from polls.models import Question >>> # create a Question instance with pub_date 30 days in the future >>> future_question = Question(pub_date=timezone.now() + datetime.timedelta(days=30)) >>> # was it published recently? >>> future_question.was_published_recently() True I run the import datetime, and from django.utils import timezone and there are no issues. Once I get to from polls.models import Question I am hit with an error message no modulenotfounderror" no module named dot env. I have tried looking at stack overflow articles and they suggested installing it via pip. So I exited my shell command and tried installing dotenv with pip. When I do so I get the following error message shown in the screenshot. I looked at this stack overflow article python … -
Implementing real time filtering/search with Django and React not working as expected
I'm trying to implement real time filtering/search with Django and React. But I'm not getting desired results? Please what did I do wrong? Here is my views.py file: class FilterFormView(generics.ListAPIView): serializer_class = JournalSerializer def get_queryset(self): qs = Journal.objects.all() title_contains_query = self.request.query_params.get("title_contains") if is_valid_query_param(title_contains_query): qs = qs.filter(title__icontains=title_contains_query) return qs The filtering Form in React looks like this: useEffect(() => { fetchJournals(); }, [title_contains]); const fetchJournals = async () => { setLoading(true); try { const res = await axios.get(myurl); setPost(res.data); setLoading(false); } catch (e) { console.log(e); } }; const handleChange = (e) => { settitle_contains({ ...title_contains, [e.target.name]: e.target.value, }); }; return ( <React.Fragment> <input onChange={handleChange} type="text" name="title_contains" id="title_contains" /> {post.map((jour) => { return <div>{jour.title}</div>; })} {loading && <div>Data is Loading</div>} </React.Fragment> ); This was how I set my url: const [title_contains, settitle_contains] = useState(""); const url = new URL("http://127.0.0.1:8000/api/?"); url.searchParams.set("title_contains", title_contains); I got this from the server console whenever I typed in the input field and no filtering occured in the frontend: [08/Jul/2023 19:40:38] "GET /api/?title_contains=%5Bobject+Object%5D HTTP/1.1" 200 2 But if url is set like this: const myurl = http://127.0.0.1:8000/api/?${title_contains}; Then I got this from the server console each time I type in the input field and no filtering occured in the … -
How to show more object information on forms in django
This is a follow up question to this question: How to pass user object to forms in Django Here is my form: class SellForm(forms.Form): symbol = forms.ModelChoiceField(queryset=None, widget=forms.Select(attrs={ 'class': 'form-control', 'placeholder': 'Symbol', 'autofocus': 'autofocus', })) def __init__(self, *args, **kwargs): self.request = kwargs.pop('request') super(SellForm, self).__init__(*args, **kwargs) self.fields['symbol'].queryset = Holdings.objects.filter(student=self.request.user.student) This form is providing me with this dropdown: I have extra information in the model which is the purchase price of each share, is there a way to get this onto the form also? It would have to be non editable though as its the price that the share was purchased at. Here is the model that the form is getting the data from: class Holdings(models.Model): student = models.ForeignKey(Student, on_delete=models.CASCADE) symbol = models.CharField(max_length=10) purchase_price = models.DecimalField(max_digits=10, decimal_places=2) class Meta: verbose_name_plural = "Holdings" ordering = ['symbol'] def __str__(self): return self.symbol I would very much appreciate any help if possible! Thank you!
