Where to put crucial credentials?
Should I put all API keys etc. inside .env and git ignore it or use the environment variables? As far as I understand .env is just the equivalent of putting passkeys into the environment, but it is easier accessible from the root directory. -

Problem with Django class-based LogoutView in Django 5.0
I used Django class-based login and logout views by "django.contrib.auth.urls", login feature works correctly, but when logging out via the link "http://127.0.0.1:8000/accounts/logout" it returns an http 405 error page, saying "method not allowed (GET)". I found out this logout feature was available in django 4.0 but in django 5.0 it's removed. Support for logging out via GET requests in the django.contrib.auth.views.LogoutView and django.contrib.auth.views.logout_then_login() is removed. -djangoproject.com How can I fix it? I think I should somehow make it use POST request instead GET request when loging out but don't know how. -
Why wagtail rich text content not being displayed in the front-end in the way expected?
I am using wagtail Rich Text Field to create content for my website paragraph = RichTextField() However, I am getting an issue where lists are not being displayed in the front-end and the font color of the content written as rich text is different from the rest of the content.

I have used the richtext filter in my template: {{ block.value|richtext }} How I entered the content: admin panel where i entered content How content was displayed: how content is being displayed -
Django : Serializer validation prevents my code from updating an existing object
I have a Django project that get some user data and store them in a database. I want my function to handle both Create and Update with the same method, so I created a view that inherit from UpdateAPIView class UserList(generics.UpdateAPIView): queryset = RawUser.objects.all() serializer_class = RawUserSerializer def put(self, request, *args, **kwargs): raw_user_serializer: RawUserSerializer = self.get_serializer(data=request.data) raw_user_serializer.is_valid(raise_exception=True) # Fail when user already exists raw_user: RawUser = RawUser(**raw_user_serializer.validated_data) // Some custom computing # Create or update raw_user self.perform_update(raw_user_serializer) return JsonResponse({'user_id':raw_user.id}, status = 201) class UserDetail(generics.RetrieveAPIView): queryset = RawUser.objects.all() serializer_class = RawUserSerializer I think that the use of a UpdateAPIView and the function perform_update() is good. It works well when the user doesn't exist already, but when I try to create a new user with the same primary key, I get : Bad Request: /api/profiling/users/, with the following response : { "id": [ "raw user with this id already exists." ] } It look like it fails on raw_user_serializer.is_valid(raise_exception=True) instruction. How can I solve my issue ? (while keeping the validation of my object) -

structlog bind method remembers previous user and logs with user_id, but after request finished it's not being cleared

Problem is for further requests, it logs previous user_id before request started, while it should be None. Id after request started is always ok.

How to add multiple parameters to a GET request in a django template?
I have a page with a table of objects. Users can choose a filter from a dropdown menu: <a href='?filter1=black'>Black</a> <a href='?filter1=white'>White</a> Which adds the filter into the GET request, like so: website.com/products?filter1=black Now I want users to be able to combine that with another filter: <a href='?filter2=black'>Small</a> <a href='?filter2=white'>Big</a> So that the GET request will look like this: website.com/products?filter1=black&filter2=small How does one usually go about this (preferably in django template language)? -

Django count satisfied filters in queryset
Good day everyone. I am trying to learn python and django for a few days now and have come across a challenge. I would like to search a model, count the filters that was satisfied (like a score), then order them by that score in descending order. I tried the following: filter_count = 3 q1 = Q(fieldA__iexact='AAA') q2 = Q(fieldB__iexact='BBB') q3 = Q(fieldC__contains='CCC') qAll = q1 | q2 | q3 results = myModel.objects.filter(qAll).annotate( match_count=Count('id') ).order_by('-match_count') for result in results : print(result.name + " : " + str(result.match_count)) percentage_score = result.match_count/filter_count * 100 I would like something like: Item1 - 3/3 match, 100% match Item2 - 0/3 match, 0% match Item3 - 1/3 match, 33% match It "partially" works, but I am definitely missing something. Since Count is not working as I expected. I would greatly appreciate some advice/pointers. -
Deploying Django on A2 hosting
I was wondering if anyone has deployed a django web-site with A2 Hosting. I will use linux, and the Debian operating system.

Appreciate any help, and interested in knowing if the customer service were informative. Cheers -
Django Elastic Beanstalk Static Configuration not working
I'm trying to deploy a Django application on Elastic Beanstalk, and had problems with my css files in the static folder generated by python3 manage.py collectstatic being read by my html templates. I digged deeper, and turns out when I SSH into the EC2 instance that is hosting my application, the file /etc/nginx/conf.d/elasticbeanstalk/01_static.conf contains location /static/ { alias /var/app/current/static; access_log off; } My application only works when I manually change this file to contain location /static/ { alias /var/app/current/static/; access_log off; } The only change here is that I added a trailing slash at the end of the alias. I looked this up more, and was recommended that I create a 01_static.config file in the .ebextensions directory within the root directory, which I did and populated with the following: files: "/etc/nginx/conf.d/elasticbeanstalk/01_static.conf": mode: "000755" owner: root group: root content: | alias /var/app/current/static/; However, this doesn't seem to do anything. Does anyone have solutions as to how I can add the trailing slash without manually SSHing into an EC2 instance on every deployment? Thanks in advance. -
CKEditor5: Image Upload Issue in Django (django-ckeditor-5)
I'm encountering an issue while integrating CKEditor5 into my Django project. Specifically, the image upload feature is not working properly.

Django: Get serialized object in save hook
Use case: On save for some of my models, I need to serialize them and send the serialized object somewhere (logging, emails etc). There's some additional things that need to happen with the serialized object. The important thing is that I need this serialized object on a save hook as there are multiple ways my model can be saved (via Rest, Django Admin, etc). However, since Django serializers import the model its serializing, this creates a circular reference. Before jumping to Signals, it should be noted that Signals have some limitations and are considered an anti-pattern. Ideally, I would like to use Django Lifecycle hooks, which are considered a more suitable and reliable hook at the model level. But this still doesn't solve the issue of calling a serializer on a save hook in a Django model. So besides explicitly calling the serializer and save methods at the View level, is there a way to serialize the object at the model's save operation? -
Make a Django application pip-installable with pyproject.toml?
I've got a couple Django projects that use the same 'shared application', which we will call shared-django-app. The shared application has it's own git repository. Recently, instead of having to run git clone after setting up the project to bring in the shared-django-app we have been considering adding it to the requirements file so it gets installed via pip when we install all the other requirements. Currently the shared-django-app repo has a structure like this: |- .gitignore |- __init__.py |- models.py |- pyproject.toml |- README.md |- views.py |- # other flat files |- static/ |- shared-django-app |- # static files |- templates/ |- shared-django-app |- # template files |- templatetags/ |- tests/ I've read that you can install directly from a git repo and that's what I think we would like to try to do. I added this to a pyproject.toml and put it in the shared-django-app repository: [build-system] requires = ["setuptools"] [project] name = "django-shared-app" version = "1.0.0" [packages] packages = [find_packages()] But I'm getting an error when I run pip install git+ssh://git@bitbucket.org:<org>/shared-django-app.git@dev : Getting requirements to build wheel ... error error: subprocess-exited-with-error × Getting requirements to build wheel did not run successfully. │ exit code: 1 ╰─> [14 … -
