How to use multiple forms in a single page in django
Hi i am pretty new to django. I am making a app for taking tiny notes. You can click on the texts (which is a django forms but it doesnt have the outlines) and edit them. I will make the submit form button appear when we change the content with javascript but for now lets leave it that way. With the "+" button you can add more Note instances. Now, the problem is when i want to edit the notes the only way i know is using forms, and when i do that i have to call another form for each Note instance...(i suppose). What i want on my website is, you can simply edit the content or title by clicking the text area, and submiting it(I can give https://trello.com as an example!). views.py def document_page(request, title): document = Document.objects.get(title=title) notes = document.notes.all() form = NoteForm(request.POST or None, request.FILES or None, instance=notes[0]) if form.is_valid(): form.save() return HttpResponseRedirect('/note/document/' + title) return render(request, 'note/document_page.html', {'document': document, 'notes': notes, 'form': form}) models.py class Note(models.Model): title = models.CharField(max_length=16, default='note-title') content = models.TextField(max_length=512, default='content') creation_date = models.DateTimeField(auto_now_add=True) document = models.ForeignKey(Document, on_delete=models.CASCADE, blank=True, null=True, related_name='notes') def __str__(self): return self.title forms.py class NoteForm(ModelForm): class Meta: model = … -

What is the workflow for Stripe's Custom Payment?
I am currently developing a payment module for my django application and I am seeking assistance. Presently, my application uses Checkout Stripe for payment processing, but I find it limiting because it doesn't allow me to fully customize the checkout page according to my preferences. Additionally, I would like to keep the users on my website during the payment process. While exploring Stripe's documentation, I came across the "Custom Payment Flow" feature, which seems to be what I need. My desired flow is as follows: when a user clicks on the "Buy product" button, they should be redirected to a checkout page that I have customized using HTML. This checkout page will include product details, a form to collect personal information, and the Stripe payment form below. I understand that when the page loads, I need to update a variable called items using jQuery or JavaScript to populate it with the specific item or items the user intends to purchase. // The items the customer wants to buy const items = [{ id: "xl-tshirt" }]; However, I am unsure about how to handle the personal information that I will collect from the user. Could someone please provide guidance on how … -
How to handle multiple `GET` query parameters and their absence in Django ORM when filtering objects?
I'm currently building a blog, but this applies to a lot of projects. I have articles stored in Article model and have to retrieve them selectively as per the GET parameters. In this case, I want to return all the articles if the language GET query parameter is not supplied and only the specified language articles when the parameter is supplied. Currently I am doing the following: # articles/views.py @api_view(['GET', ]) def articles_view(request): """ Retrieves information about all published blog articles. """ language = request.GET.get('language') try: if language: articles = Article.objects.filter(published=True, language__iexact=language).order_by('-created_at') else: articles = Article.objects.filter(published=True).order_by('-created_at') # articles = Article.objects.first() except: return Response(status=status.HTTP_404_NOT_FOUND) serializer = ArticleSerializer(articles, many=True, exclude= ('content', 'author',)) data = serializer.data return Response(data) I feel this can be improved and condensed to a single Article.objects.filter(). The use of if for every query param seems inefficient. This is especially required since the articles will later also be retrieved via tags and categories along with language in the GET query parameters. With the expected condensed querying, there would be less if conditional checking and the freedom to include more query params. Can someone please help me with this? -
Django - multiple pages using one form
There's a number of questions regarding one page and handling multiple forms but I seem to have the reverse issue. I have two pages that contain datatables showing filtered data from my model, but both are the same source data and every object (in both tables, on both pages) has the same "edit" button bringing the user to the same form allowing them to edit the object details. My problem is redirecting from the form to the original page. I have tried using HttpResponseRedirect but that doesn't seem to be working, it goes to my homepage everytime. def edit_drawing(request, drawing_no): drawing = get_object_or_404(Drawings, pk=drawing_no) if request.method == "POST": form = DrawingForm(request.POST, instance=drawing) if form.is_valid(): form.save() messages.success(request, f'Drawing {drawing.drawing_no} was successfully updated.') return HttpResponseRedirect(request.META.get('HTTP_REFERER', '/')) else: form = DrawingForm(instance=drawing) return render(request, 'edit_drawing.html', {'form': form, 'drawing': drawing}) I thought I could do something like this where my tag in the original html would tell the redirect where to go if I passed a variable: <a href="{% url 'schedule:edit_drawing' drawing_no=your_drawing_no %}?next={{ request.path }}">Edit Drawing</a> But when I try to use return redirect(next_url) in the view, next_url is undefined and doesn't work. Does anyone have a best practice to handle something like this? I … -
Django migration error: Applying migrations throws an error, and querying 'flight.objects.all()' results in an error as well
I'm facing an issue with my Django project where I encounter errors when trying to apply migrations using python manage.py migrate and when executing flight.objects.all(). Here's the code: from django.db import models # Create your models here. class Flight(models.Model): origin = models.ForeignKey('airport', on_delete=models.CASCADE, related_name="departure") destination = models.ForeignKey('airport', on_delete=models.CASCADE, related_name="arrival") duration = models.IntegerField() def __str__(self): return f"{self.origin} to {self.destination}" class Airport(models.Model): city = models.CharField(max_length=64) code = models.CharField(max_length=3) def __str__(self): return f"{self.city} ({self.code})" The Flight table previously had two Character fields instead of foreign keys and I had stored a row in it but later I decided use Airport table as a foreign key in Flight table. However after I exited the shell and tried to run "python manage.py migrate" I got an error: django.db.utils.IntegrityError: The row in table 'flights_flight' with primary key '1' has an invalid foreign key: flights_flight.origin_id contains a value 'Kathmandu' that does not have a corresponding value in flights_airport.id. I figured it might be because of the previously stored data in the Flight table so i tried to delete it, however i cant even view the contents of the Flight table. Whenever i try running "flight.object.all()" i get another error: django.db.utils.OperationalError: no such column: flights_flight.origin_id Can anyone help … -

Best way to old "version" of specific parameters on django model
I want to do a "version control" kind of thing. I have a django model called "Person" I also have a method of updating all persons "gender" and "language" according to "detection" version. this method improves from version to version. I dont want to "detect" gender of person in latest version to not over use resources, each detection cost ... my method need to run over all persons with gender version 1 or language version 1 and update the person lang and gen to version 2 (run the method). so the simple is: class Person(models.Model): phone = models.CharField(max_length=50, blank=True, null=True) phone_version = int ... language = models.ManyToManyField( "instagram_data.Language", verbose_name=_("language_code_name"), blank=True) language_version = int ... but I have also 20 more filters (like gen and lang) so I prefer to have one attribute named version, so I could filter also in a simple way. if I do ManyToManyField to class Version it will be slow to do filters, right ? class Person(models.Model): phone = models.CharField(max_length=50, blank=True, null=True) language = models.ManyToManyField( "instagram_data.Language", verbose_name=_("language_code_name"), blank=True) version_control = models.ManyToManyField(DetectionVersion ...) class DetectionVersion(models.Model): phone_version = int ... language_version = int .. is the second fast and a good solution ? -
Wrong distance between two points in Geodjango
I have user class: class User(AbstractBaseUser): location = PointField(srid=4326) and I calculate distance between two points in serializer this way: obj.location.distance(request.user.location) * 100 For example I have two points: POINT(-95.3385 29.7245) POINT(-85.3385 29.7245) One point is for authorized user the other is for the other user. Serializer returns 1000 kilometers. I don't know what is latitude and longitude and it doesn't matter because in online calculators in one case it is a little bit more than 1000 km and in the other - a little bit less than 1000 km. And it is never 1000 km. Any ideas why this is happening? -

DRF: Serializer update method returns KeyError during partial update, instead of ValidationError raised by model clean() method
In Django Rest Framework, I'm testing one of the endpoints for proper exception handling. A ValidationError is expected but instead a KeyError is returned. I've been trying to debug this case for a while now so here's the step-by-step breakdown of what happens: Step 1: Incoming data gets serialized: class BatchIdView(APIView): ... def patch(self, request, batch_id): ... serializer = BatchSerializer(batch, data=data, partial=True) if not serializer.is_valid(): return Response(data=humps.camelize(serializer.errors), status=status.HTTP_400_BAD_REQUEST) There are no custom validators in this serializer and data is validated during this step (is_valid() method returns True) Step 2: Attempting to update the object (actually this code comes directly following previous snippet): try: serializer.update(batch, serializer.validated_data) except ValidationError as e: return Response(data=humps.camelize(e.messages), status=status.HTTP_400_BAD_REQUEST) except Exception as e: return Response(data={"error": str(e)}, status=status.HTTP_501_NOT_IMPLEMENTED) Step 3: During the update() method, model's save() method triggers validation: class Batch(models.Model): ... def save(self, *args, **kwargs): self.full_clean() return super().save(*args, **kwargs) def clean(self): if self.product_type in ["..."] and self.model is not None: raise ValidationError({"model": "error text goes here"}) I've double-checked that this raise ValidationError() line gets triggered in that particular test case. Step 4: Instead of returning the validation error, the serializer decides to trigger to_representation() method which is customized and is checking for another field: def to_representation(self, instance): … -

In Django, given an instance of Model A, how to define a relation between two instances of model B?
What (I think) I'm trying to achieve is to create a new column in my database (resp. a new field in my model) for model B every time there is a new instance of model A. To clarify, say I have the following model in Django : class Unit(models.Model): unit = models.CharField(max_length=200) with two instanciations : Kilograms and Volume (m^3). I'm looking to specify the following class: class Object(models.Model): object = models.CharField(max_length=200) # Field to relate `Volumes` to `Kilograms`, as a float so that I'm able to declare the relation between Kilograms and Volume (m^3) for each specific object. In a way, I'm trying to declare a float that relates the volume for each kilogram of the object (or vice-versa). I could use a workaround and add a FloatField if I knew Kilograms and Volume would be the only instances of Unit, but unfortunately, there might be others. PS: Additional (less important) question: Could I select a default unit, and declare the other ones compared to that default unit. Something like the following: class Object(models.Model): object = models.CharField(max_length=200) default_unit = models.ForeignKey(Unit, on_delete=models.CASCADE) # Field to compare unit_1 to default_unit # Field to compare unit_2 to default_unit # And so on … -
