Redirection after submit not working after adding extra code on top. Probably a priority problem
I have a script that redirects the user to the previous page_id after submit: a user would connect to page page_A Would click on product_1, Be redirected to product_1 page, Leave a review and upon clicking submit be redirected to page_id This has been working fine for a while. I decided to implement djang-hitcount in a function base view (used the code here how to use Django Hitcount in a function based view rather than a class?), as I wanted to see how many unique IP addressed where connecting. Since then the comment submission code is not working anymore. As an example: If User land on Page_A the URL would show this: http://localhost:8000/Page/A When clickin on product_1, the url would then display the following:http://localhost:8000/product/1?next=/Page/A When submitting a review the user would be redirected to : http://localhost:8000/Page/1 However now, the user is redirected to http://localhost:8000/Page/1 which obvioulsy does not exist - it should be Page A, but instead attributes the product_id to the page_id. I suspect it's because the new django-hitcount code has taken over some of the initial logic. Maybe some indention problem? Here it goes: Views.py def show_event(request, event_id): submitted = False form = 'ReviewForm' formonpage = 'ReviewForm' ###<-- … -
Django and Flutter configuration
How do i configure Django and Flutter for local development and how do i configure them for the deployment in a server? (Flutter as a frontend web project). I have tried to add static files directories in settings file. But I'm not sure what value do i give to this variable. Do i assign os.path.join(BASE_DIR, 'flutter_project/build/web/assets') to static files directories or do i have to assign something else? Now that you’re ready to post your question, read through it from start to finish. Does it make sense? -

Request Pending After A DELETE request
I am working with Reactjs and I am having and issue while sending request, Last week everthing was working perfectly and then I started to face that request issue. When I send GET, PUT, POST request everything works fine with no problems, when I send a DELETE request it gets sent and I recieve a response with status 204, but any type of request I send after it, it stucks in a pending state forever. I tired different Projets same issue, different PC same issue. When I access my dev server from another PC everythings works perfectly no problems, seem like the problem happens only when I send request from the same machine where the dev server is strated.

Fetching users data based on username input in urls
I am little bit new to django and was working on my first instagram clone project all by myself. I got confused in a place where I needed to fetch user data based on 127.0.0.1:8000/username and I found a useful but useless answer(for me) from medium(.com) .The author was using class based view. In class based view, I didnot get any documentation to use multiple models as much as I searched so i had to do it with function based view as I have not learned class based view yet.I had to use post model, profile model and User model to get data for profile page. This is the code that somehow worked but should I use this view? from django.contrib.auth.models import User from .models import Profile #profile view def profile_data(request, username): mydata = User.objects.get(username=username) myprofile = Profile.objects.filter(user=mydata) mycontext ={'profile': myprofile} return render(request,'firstapp/profile.html', context=mycontext) #in urls.py, from firstapp import views path('<str:username>/', views.profile_data , name='profile'), #in models.py, from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE,unique=True) fullname = models.CharField(max_length=100) def __str__(self): return self.fullname In firstapp/profile.html, <a href="#" class="text-3xl mt-5 text-center">{{user.profile.fullname}} But I got confused on how to attatch my Profile model in it.

How to resolve a 502 Bad Gateway when deploying Django App on Azure with Gunicorn and Nginx
I've been trying to deploy a Django app on Azure for about a week. My instructor followed the exact same setup I used and he was able deploy the same app to Azure. I've followed several tutorials, this one from Digital Ocean in particular, and I always get the same result. When I go the the IP address I get a 502 Bad Gateway. The only change I make from the tutorial is opening up ports 8000 and 80. I do that through Azure's Networking settings. I've tried all of the troubleshooting recommendations at the end of that tutorial. I've restarted Gunicorn, Nginx, and even the VM. On Azure I have a Standard B1s VM running Ubuntu 22.04. I do not have a custom domain, just the static IP assigned by Azure. I can deploy the app on the development server just fine. If I bind 0.0.0.0:8000 to gunicorn that also will display the site (minus styling). Gunicorn starts and runs. When I check the status after starting the service it shows the active green dot. Immediately after trying to access the site via the IP address, if I check Gunicorn status again it reads: gunicorn.socket: Failed with result 'service-start-limit-hit' … -

I need help properly implementing a booking scheduler and availability in Django
This question has been asked many times before on StackOverflow and in the Django forums, but none of the answers I've found are appropriate or complete enough for my situation. First, the brief: I'm creating a web application for a car rental business. In addition to helping them organize and centralize their fleet, it will also help them collect orders directly from customers. As with most rentals, the logistics of it all can be somewhat confusing. Someone may place an order for a car today (December 12th) but actually take the car over the Christmas to New Year's period. A renter may borrow a car for just two days, and then extend the booking at the last minute. When this happens (often very frequently), the business usually has to scramble to find another one for a different customer who was scheduled to get that car the next day. Adding to that, an individual car can only be rented to one client at a time, so it can't have multiple bookings for the same period. Most answers advocate for a simple approach that looks like this: models.py class Booking(models.Model): car = models.ForeignKey(Car, ...) start_date = models.dateField(...) end_date = models.dateField(...) is_available = … -

Celery not retrying when an exception is raised when testing in Django
I have a class based celery task, which I would like to test by raising an error and then confirming that retry has been called. During the test, I want to raise a ConnectionError when msg.send() is called and then confirm that it is being 'retried'. The task essentially constructs an email using django.core.mail.EmailMultiAlternatives (which inherits EmailMessage) and then attempts to send that email. The task works well in practice, with a retry being called if a connection does not exist, my only problem is how to test it. So far, I have managed to raise the ConnectionError by patching EmailMultiAlternatives, however, the test does not trigger a retry in the celery terminal. tasks.py (Simplified) class SendMail(Task): max_retries = 4 base = 'BaseTask' def run(self, **kwargs): msg = EmailMultiAlternatives(kwargs.get('some_value'), etc.) msg.attach_alternative(rendered_html) try: msg.send(fail_silently=False) except ConnectionError as exc: self.retry(countdown=backoff(self.request.retries), exc=exc) test_task.py (simplified) class SendMailTest(TestCase): def setUp(self): self.message = {some data} def test_error(self): with patch.object(EmailMultiAlternatives, 'send', return_value=None) as mock_method: mock_method.side_effect = Exception(ConnectionError) SendMail(kwargs=self.message) My question is, why, when the test script is run and an exception is clearly being raise, does Celery not attempt to retry? -

I create foo to upload files to Django models, its InMemoryUpload object. and how can I collect the full path to download link? my models.py class Document(models.Model): """Class for uplaoded files. colect file and description working with analog form """ id = models.AutoField(primary_key=True) file_path = models.TextField(max_length=255) hash_size = models.CharField(max_length=255) def __str__(self): return f"{self.id},{self.file_path},{self.hash_size}" def get_hash(file: object) -> str: md = hashlib.md5() # with open(file, "rb") as f: for chunk in iter(lambda: file.read(4096), b""): md.update(chunk) return md.hexdigest() my views.py def model_form_upload_1(request: HttpRequest) -> HttpResponse: ''' view handling this form will receive the file data in :attr:`request.FILES <django.http.HttpRequest.FILES>`''' if request.method == 'POST': upload = request.FILES['file'] path = upload.chunks() print(path) hash_tuple = () form = DocumentForm(request.POST, request.FILES) if form.is_valid(): print(upload.size) if get_file_size(upload): hash = Document.get_hash(upload) hash_list = [x for x in Document.objects.all().values_list('hash_size')] hash_tuple += (hash,) if hash_tuple not in hash_list: Document.objects.create( file_path=request.GET.get(upload), hash_size=hash) else: return HttpResponseBadRequest("file bigger tha 300mb") return redirect("view") else: return HttpResponseBadRequest("Form invalid") else: form = DocumentForm() return render( request=request, template_name='model_form_upload.html', context={'form': form}) return render(request, 'model_form_upload.html') return render(request, 'model_form_upload.html') my template.py <tr> <td>{{document.id}}</td> <td>{{document.file_path}}</td> <td><a href="{{ document.file_path }}">download</a></td> <td>{{document.hash_size}}</td> </tr> before I tried to take request.open(file) but it's actually not what I need.
