How to set next_url in Middleware?
I'm writing a custom piece of Middleware for my Django project that will redirect every page request to an age gate if the user has not yet confirmed they are old enough to enter the page. I want the age gate page to redirect to their originally requested page when they have confirmed the age gate. My middleware right now looks as follows: from django.shortcuts import redirect class AgeGateMiddleware: EXCLUDED_URLS = ['/preview/agegate'] def __init__(self, get_response): self.get_response = get_response def __call__(self, request): if not request.session.get('agegate') and request.path not in self.EXCLUDED_URLS: request.session['next_url'] = request.path return redirect('/preview/agegate') response = self.get_response(request) return response And my age gate view looks like this: def age_gate_view(request): #Load the original page after checking age gate. next_url = request.session['next_url'] #Register users IP for age gate. x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') if x_forwarded_for: ip = x_forwarded_for.split(',')[0] else: ip = request.META.get('REMOTE_ADDR') try: ip =ip except: ip = 'none' form = AgeGateForm({'ip':ip}) #Store age gate response if request.method == 'POST': form = AgeGateForm(request.POST or None, {'ip':ip}) if form.is_valid(): form.save() request.session['agegate'] = 'welcome' return redirect(next_url) context = { 'form':form, } return render(request,'Academy/agegate.html', context) Right now the Middleware works as intended: It redirects to the age gate if this has not yet been confirmed.

Django User Is Logged Out outside the home page

How can i make ManyToMany admin pannel on django?
I made a ManyToManyField in Django, but it dosen't seem like i can edit it in django admin. After reading some documents, I found out that I needed to add some kind of widget, so I added filter_horizontal=('collections',) (which was shown in Django Admin ManyToManyField) but this seems to cause an error.

Dockerizing Django and Nginx - How can I Retrieve the Client IP Instead of the Bridge Network Gateway IP in Django with Docker?
I'm currently facing an issue with my Django application where, despite including the X-Real-IP and X-Forwarded-For headers in the request, I am still retrieving the gateway IP instead of the actual client IP. I have implemented a middleware to print the headers, and the logs consistently show the gateway IP. Here's a snippet of the relevant headers from the middleware logs: DebugHeadersMiddleware ================================== django_app | HTTP_X_REAL_IP : 172.30.0.1 django_app | HTTP_X_FORWARDED_FOR : 172.30.0.1 django_app | HTTP_HOST : localhost django_app | REMOTE_ADDR : 172.30.0.4 =========================================================== expected HTTP_X_REAL_IP or HTTP_X_FORWARDED_FOR to contain the client's IP, but it seems that the gateway IP is being retained.

How to reuse method for different classes?

Django Allauth Facebook login send me to "login cancelled" page
I am making an app in Django and using the allauth library to enable Facebook login. I set up everything accordingly in my Django project and the FB Developer console (I am pretty sure of this because my Google login works), but when I click on the "Login with Facebook button", a popup window appears with a Facebook page asking me to login, but my app is already in the login cancelled page in the following URL: "https://www.xxxxxxxxxxxxxx.com/accounts/social/login/cancelled/". If I login in the popup window nothing changes in my app and the popup just closes. The weirdest thing is that I am not getting any error or warning logs. This happens both in development and production mode. I read in other posts that adding "ACCOUNT_DEFAULT_HTTP_PROTOCOL = 'https'" in settings.py can solve the issue, but it did not work for me. Has anyone had a similar problem and know the solution to this? -

How can I run Daphne with a configuration file? What is the equivalent Daphne command to gunicorn -c lu_development/gunicorn.conf.py lu_development.wsgi:application? Are there any specific parameters or considerations when using a Daphne configuration file? I would appreciate any guidance or examples on running Daphne with a configuration file, and any insights on differences or similarities between Gunicorn and Daphne configuration setups. Thanks! -
Swagger UI customization in DRF (Django) using drf-spectacular
I am currently trying to document apis of my DRF project. I have read many articles on how to customize swagger api definition .

Slow Performance with Django and Remote PostgreSQL on Docker - Local vs. Production Environment
I'm encountering a significant performance issue with my Django application when using a remotely hosted PostgreSQL database in a production environment. My setup involves a Django application running locally and connecting to a PostgreSQL database hosted on a server. Local Environment: Both Django and PostgreSQL are running locally.

I am trying to upload an image from input field but when I check from database (using Value in Editor), it shows blank both binary and text. I'm new to uploading image, so I'm not sure what's missing in my code. I added media root on settings.py and urls.py. Here is my code. models.py class ImageUpload(models.Model): idupload = models.AutoField(db_column='idupload', primary_key=True) image = models.ImageField(db_column='image', upload_to="media/", null=True) description = models.CharField(db_column='description', max_length=50, null=True) class Meta: managed = True db_table = 'image_upload' upload.html <form method="post" action="" enctype="multipart/form-data" > {% csrf_token %} <div class="form-group"> <label>Upload File</label> <input class="form-control" name="image" type="file" required> </div> <div class="form-group"> <label>Description</label> <input class="form-control" name="description" required> </div> <button type="submit" name="upload" class="btn btn-gray-800 mt-2 animate-up- </form> views.py def uploadPayment(request): if request.method == 'GET': return render(request, 'upload.html') if request.method == 'POST': image = request.FILES.get('image') description = request.POST.get('description') Image.objects.create(image=image, description=description) return redirect('/images/') I tried above code but I kept on getting nothing. -
django how to prefetch with an Integer?
models class Challenge(models.Model): name = models.CharField(...) version = models.IntegerField(...) class Workout(models.Model): name = models.CharField(...) version = models.IntegerField(...) # this field may not exist # this is a through table class ChallengeWorkoutRelation(models.Model): challenge_id = models.IntegerField() # for some reason, this is IntegerField, not ForeignKey workout_id = models.IntegerField() # for some reason, this is IntegerField, not ForeignKey version = models.IntegerField(default=0) I want to get all workouts belong to one challenge: for relation in ChallengeWorkoutRelation.objects.filter(challenge_id=challenge.pk, version=challenge.version): workout = Workout.objects.get(id=relation.workout_id) # do something with workout... # another version # workout = Workout.objects.get(id=relation.workout_id, version=challenge.version) Can I optimize this code to get more performance? -
Capture Coordinates on PDF in React.js - Similar to DocuSign clone
I'm working on this project which kind of similar to DocuSign. User will upload a pdf and drags and drops textboxes and will save it as templates. I need to store the x and y coordinates along with the label for that textbox. And when the user re-opens the template, he has to see the pdf along with the fields placed on the pre-set coordinates. This info is used in the backend to generate the output pdf using a python script. I'm done with the python script part and planning to use this in django. I don't know how to achieve the coordinates grabbing part. I researched a bit and found a couple of libraries "react-pdf" for pdf viewing and "react-dnd" for drag and drop. Can I achieve the requirement using these two libraries? If you have any other better suggestions, please let me know. Thank you so much in advance.
