How to replicate RegisterSerializer.custom_signup for social signups
I have overridden RegisterSerializer.custom_signup (REGISTER_SERIALIZER) to set certain parameters in the user's profile based on cookie values and it works fine when a user registers using email/password. However, what I realized was that it's not getting called when the user registers through social (Google, specifically). I found SocialLoginSerializer.post_signup which sounds like it might be the right place to inject similar logic, but I am not sure how to tell dj_rest_auth to use the overridden class. There does not appear to be an equivalent to the REGISTER_SERIALIZER config variable that points to the new class. I also considered moving this logic to User's post_save signal event, but unfortunately one can't access the request therefore any cookies from there (without some middleware acrobatics). I am using dj_rest_auth 4.0.1 and allauth 0.50.0 Thanks in advance for any pointers. -
How can I filter my contacts by user that it belongs?
I need to show names that belong only to one user.. models.py class Contact(models.Model): name = models.CharField(max_length=50, null=False, blank=False, unique=False) surname = models.CharField(max_length=50, null=True, blank=True, unique=False) father_name = models.CharField(max_length=50, null=True, blank=True, unique=False) dob = models.DateField(null=True, blank=True, unique=False) photo = models.ImageField(upload_to='static/photos/', null=True, blank=True) email = email = models.EmailField(max_length=254, null=True, blank=True, unique=False) phone_number = models.CharField(max_length=12, null=False, blank=False, unique=False) contact_belongs_to = models.ForeignKey(User, on_delete=models.CASCADE) views.py def post(self, request:HttpRequest)->HttpResponse: form = ContactForm(request.POST) if form.is_valid(): Contact.objects.create(name=form.cleaned_data['name'], surname=form.cleaned_data['surname'], father_name=form.cleaned_data['father_name'], dob=form.cleaned_data['dob'], photo=form.cleaned_data['photo'], email=form.cleaned_data['email'], phone_number=form.cleaned_data['phone_number'], contact_belongs_to=request.user).save() return HttpResponse('OK') else: return render(request, 'contacts/contact_form.html', context={'form':form}) this is how 'contact_belongs_to' takes value->user And when user wants to see only his own contacts I should filter them by 'contact_belongs_to' or no? Could you help please... -

Chaining django queries on dates not working as expected
I have a Django 4.2 app with a model Album. The Album model has a DateTimeField called date. I run a query to select albums by the year in launch_date: >>> launch_date = datetime(2014, 5, 10) >>> albums = Album.objects.filter(date__year=launch_date.year) >>> albums <QuerySet [<Album: 732 - September 30, 2014>, <Album: 734 - February 6, 2009>, <Album: 735 - March 29, 2010>, <Album: 736 - April 5, 2010>, <Album: 738 - May 20, 2014>]> >>> for a in albums: print(a.album_id, a.date.year, a.date.month) 732 2014 10 734 2014 10 735 2014 10 736 2014 10 738 2014 5 Which is what I expected. However, when I run this query to further filter the albums by month, it fails. I expected the query to return the one album with album_id = 738: >>> albums.filter(date__month=launch_date.month) <QuerySet []> These chained filters do not produce the results I expected, either: >>> Album.objects.filter(date__year=2014, date__month=5) <QuerySet []> >>> Album.objects.filter(date__year=launch_date.year).filter(date__month=launch_date.month) <QuerySet []> What am i doing wrong? -
Django messages with javascript fetch() API and redirect
I am doing a request with the fetch() API to a django view, which will set a message with the messages app and redirect the request. I can capture the redirect with response.redirected and the messages-cookie is set, but when i do the redirect with location.replace, the messages get lost. How do i pass on the messages from the original response? The django view: def add(request): if request.method != 'POST': return HttpResponse("not post") pproject = request.POST['pproject'] print("pproject:", pproject) messages.add_message(request, messages.INFO, "Test.") return redirect("project_detail") my urls.py: path('project/add/', views_project.add, name='project_add'), and in my template (javascript): var csrftoken = document.querySelector('[name=csrfmiddlewaretoken]').value; const headers = new Headers(); headers.append("X-CSRFToken", csrftoken); const form = new FormData(); form.append("pproject", "{{ project.id }}"); const ops = { method: "POST", headers: headers, body: form, credentials: "same-origin" }; const req = new Request("{% url 'project_add' %}"); fetch(req, ops) .then((response) => { if (response.redirected) { console.log("response redirect:", response); window.location.replace(response.url); return false; } else if (!response.ok) { throw new Error(`HTTP error!

Passing Form Data to pre-select django-filter sets before loading view
My problem: I'm utilizing Django and bootstrap4 crispy forms to simply display data from one of my database tables with a django-filters included in order to provide more in-depth information. The issue is, this table can have upwards of 20 million records. Though I've implemented a pagination technique to allow for loading all 20 million records rather quickly... it is still not ideal! What I would like to do is create a non-model-based form that I can use to get the request.POST.get() data and load the view with 2 of my django-filters selected and "locked." I already have the form and structure in place to successfully load all records and filter, I'm just not quite sure how to actually pass the data from my form to my view and render it with 2 filters pre-selected, locked so users can't change them... I know I'll need to load the model based on the filter selection but need help with how to pass that data and use it to render the view with filters pre-selected and applied. Consider the example/flow below as expected behavior: example flow -

Do redirect with a imported function in a called view
I have a Django App "A" with a view "view_A" where I execute a function: from app_B.views import usercheck_B def view_A(request): function_B(request) return render(request) And in my Django App "B" with a function "usercheck_B": def usercheck_B(request): if not request.user.is_authenticated: redirect('view_B:login') What I want is, that a directly redirect the client if he is not logged in in the called function. But that is not working. I only can return a Httpresponse to my first called view "view_A" a redirect to login. My idea is to place the usercheck_B function in every view I have and redirect visitors. But I want to do this check also in special cases if for exapmple other parameters are not fitting. -

Troubleshooting TemplateDoesNotExist Error in Django Despite Correct Configuration
I'm relatively new to Django and encountering an issue with template loading in my project. Despite following tutorials and setting up my project structure correctly, I'm facing a TemplateDoesNotExist error. Here's my project structure: storefront\__pycache__ storefront\storefront\__init__.py storefront\storefront\asgi.py storefront\storefront\settings.py storefront\storefront\urls.py storefront\storefront\wsgi.py playground playground\__pycache__ playground\migrations playground\templates playground\__init__.py playground\admin.py playground\apps.py playground\models.py playground\tests.py playground\urls.py playground\views.py db.sqlite3 manage.py In my settings.py, the template configuration is as follows: python TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] However, when trying to render a template using the render function in my view: #python from django.shortcuts import render def say_hello(request): return render(request, 'playground/hello.html') I'm encountering the TemplateDoesNotExist error for playground/hello.html. I've verified my project structure, and it appears to be correct. Could someone provide guidance on what might be causing this issue and how to resolve it? Any beginner-friendly explanations or suggestions would be greatly appreciated! -
Django behind Apache and Traefik and CSRF
I use Cookiecutter Django as a starter for my projects, and it uses Traefik (within a Docker container) to generate certificates using Let's Encrypt. However, my company mandates the use of Apache as the proxy for all servers, and the management of the Apache server is handled by another team. To accommodate this, I disabled the Traefik certificate generation, made necessary configuration changes, etc. Everything was functioning correctly, except for the CORS protection. I encountered a 403 error on every POST request, and the log indicated the following warning: WARNING 2024-02-09 08:49:15,953 log Forbidden (Origin checking failed - https://example.com does not match any trusted origins.): /accounts/login/ Upon investigating, I found that adding the setting CSRF_TRUSTED_ORIGINS solves my problem. Adding CSRF_TRUSTED_ORIGINS=https://example.com to my config file resolved the issue. My question is: is this approach considered unsafe? -
Django Ajax & the Prevention of Refresh on Form Submission
So I have Django-based from which works perfectly (I know, something actually works for once, whoop-de-do! Who knew?), submits as expected with no issues whatsoever. However, Ajax is another kettle of fish. This Ajax script is supposed to tell the browsers not to refresh the page when the user submits information using the form below. Although strictly speaking it, it actually does stop the browser window from refreshing, it also turns the submission button into a dead.

http://127.0.0.1:8000/ This site can’t be reached127.0.0.1 refused to connect
I created my program in pycharm. It is a series of questions for the user that adds their inputs and get a result from it, pretty basic stuff. I want to share the program with my colleagues, but they are not interested in the coding part, they want to see how it works. So I thought did a little research and decided to test Django. I installed django 4.2.10 and followed chatgtp's steps.

If I try to open http://127.0.0.1:8000 in the browser it says the site cannot be reached. I have verified everything, connection, firewall, and all suggestions from chatgpt.

django migrate with clickhouse
I have a project with two databases: PostgreSQL and Clickhouse. To interact with Clickhouse, I use the django-clickhouse-backend lib. For a long time, I did not use the created migrations for this database, but created tables using raw SQL. Now it's time to apply all the previous migrations, but I ran into a problem. To avoid all conflicts, I had to significantly edit the existing migration files, after that I locally modeled and checked the application of these migrations in the existing database and everything was OK. But when I tried to apply these migrations on the production server, I got the following error: # python manage.py migrate --database clickhouse --fake-initial Operations to perform: Apply all migrations: admin, auth, authtoken, celery_app, contenttypes, django_dramatiq, edl, sessions, users Running migrations: Applying contenttypes.0001_initial...Traceback (most recent call last): File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/dbapi/cursor.py", line 111, in execute response = execute( ^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_backend/driver/client.py", line 53, in execute rv = self.process_ordinary_query( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 571, in process_ordinary_query return self.receive_result(with_column_types=with_column_types, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 204, in receive_result return result.get_result() ^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/result.py", line 50, in get_result for packet in self.packet_generator: File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 220, in packet_generator packet = self.receive_packet() ^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/clickhouse_driver/client.py", line 237, in receive_packet raise packet.exception … -
Upload issue in Django
Please can someone help with an issue i'm having in Django? I've created a recipe app for a course project and want the user to upload images. I've set the model up and when I upload an image from the django admin page it works perfectly, however when I try and upload an image from the user interface, it doesn't work and it should be using the same model. The other CharField, TextField and IntergerField all work but not the ImageField and I don't know why. There is also a default no_picture.jpg however it doesn't use that either. when the Img works the url shows as and when it doesn't the /recipes/ is missing from the URL However I don't think there is an issue with my urlpatterns as the other data works its just the image. Here is the models.py class Recipe(models.Model): name = models.CharField(max_length = 120) cooking_time = models.IntegerField(help_text = 'in mintues', default = 0 ) ingredients = models.CharField(max_length = 300) description = models.TextField() pictures = models.ImageField(upload_to = 'recipes', default = 'no_picture.jpg') forms.py class CreateRecipeForm(forms.Form): name = forms.CharField(max_length=50, required=False) cooking_time = forms.IntegerField(help_text='in minutes', required=False) ingredients = forms.CharField(max_length=300, required=False) description = forms.CharField(max_length=500, required=False) pictures = forms.ImageField(required=False) views.py @login_required def … -
ValueError at (url) seek of closed file in Django app
I am trying to add an image processing library inside a webodm django app that takes input image path, output directory path. I do not want to save the input image inside the database so I was implementing the image processing on the fly. I end up getting: ValueError at /plugins/diagnostic/ seek of closed file here is part of my view that handles the image processing: def vegetative_indices_view(request): print(cv2.__version__) if request.method == 'POST': form = VegetativeIndicesForm(request.POST, request.FILES) if form.is_valid(): uploaded_image = form.cleaned_data['input_image'] # Read the uploaded image into memory uploaded_image.seek(0) image_data = uploaded_image.read() uploaded_image.close() # Create an in-memory file-like object for the image in_memory_file = BytesIO(image_data) in_memory_file.name = uploaded_image.name # Normalize the uploaded image normalized_image = normalize(Image.open(in_memory_file)) # Call the vegetative indices calculation logic indexes = calculate_vegetative_indices(normalized_image) return render(request, self.template_path('vegetative_indices_results.html'), {'indexes': indexes}) else: form = VegetativeIndicesForm() return render(request, self.template_path("vegetative_indices.html"), {'form': form}) and in the terminal the error is printed like so: webapp | return func(*args, **kwargs) webapp | ValueError: seek of closed file What could be the issue here where the image file is prematurely closed? -
Can not access the values of dictionary using jinja
Here is my views.py def following(request): currentUser = User.objects.get(pk=request.user.id) currentUser_followings = Following_System.objects.get(user=currentUser).following allPosts = Post.objects.all().order_by("-timestamp").reverse() followingPosts = [] for user in currentUser_followings.all(): for post in allPosts: if post.author == user: followingPosts.append(post) **post_likers_ids = {post.id: list(post.likers.values_list('id', flat=True)) for post in followingPosts}** # Show 10 posts per page. paginator = Paginator(followingPosts, 5) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) return render(request, "network/following.html",{ "page_obj": page_obj, "post_likers_ids" : post_likers_ids }) I debug, and the post_likers_ids return: ({4: [2], 2: [1,3,5]}) And now in my following html why the if condition is always false (Although it should be true for some, cause I know the expected input output): {% for post in page_obj %} <div class="list-group-item"> {% with post_id=post.id %} {% if user.id in post_likers_ids.post_id %} <p>The user liked this </p> {% else %} <p>The user have not liked this </p> {% endif %} {% endwith %} </div> {% endfor %} Here is my model if that helps: class Post(models.Model): content = models.TextField(blank=False) author = models.ForeignKey("User", on_delete=models.CASCADE, related_name="author") timestamp = models.DateTimeField(auto_now_add=True) likers = models.ManyToManyField("User", related_name="liked_posts", blank=True) def serialize(self): likes_count = self.likers.count() # likers = [user.id for user in self.likers.all()] return { "id": self.id, "content": self.content, "author": self.author.username, "author_id": self.author.id, "timestamp": self.timestamp.strftime("%b %d %Y, %I:%M %p"), "likes": …
