How to properly type client.post response in django test?
@pytest.mark.django_db def my_test( self, client, ): with monkeypatch_requests(resp_json={'values': []}): r: JsonResponse = client.post( self.endpoint, self.request_payload, content_type='application/json', ) assert r.status_code == 201, r.content assert r.json() == {'key': value} PyCharm is complainging Unresolved attribute reference 'json' for class 'JsonResponse', but I can use it. When I run the test in debugger and hover over json I can see functools.partial(<bound method ClientMixin._parse_json of <django.test.client.Client object at 0x7f3b81399d30>>, <JsonResponse status_code=201, "application/json">) -

I can not find mod_wsgi model in Apache modules environment - Django
I am new to Django and I tried to connect it with Apache through mod_wsgi but it seems new versions of Apache does not support such kind of module. Am I right? Or is there any different way I could deploy my Django project in production? I saw on the official page I could use nginx. Any opinions? -
Django threaded / nested comments
What's the best way to implement threaded/nested comments in Django? I've read a bit about MPTT and django-threadedcomments but all the posts seem to be from years ago. Is using MPTT still the 'accepted' way or is there a newer way to do it? -
nowait or another method in Django admin page
I'm using Django and trying to find something similar to nowait=True in Django admin page. I have some script which locks entries(select for update) during working. So, when I try to change some fields values in Django admin page for that entry when its locked, admin page waits for unlocking that entry(in my case it could take minutes). I want to raise error(something like "database entry is locked") in admin page without waiting for unlocking. -
Django request.session.get() returns None across different view classes
I am working on a Django project and I'm encountering an issue with session variables. I set a session variable in one view, but when I try to access it in another view, it returns None. Here's a simplified version of my code: In my LoginVerification view: from rest_framework.views import APIView from rest_framework.response import Response class LoginVerification(APIView): def post(request): # ... login logic ... # If login is successful, I store the AWS access key in the session request.session['aws_access_key'] = 'your-access-key' return Response({"message": "Login successful"}) In my BucketSize view: from rest_framework.views import APIView from rest_framework.response import Response class BucketSize(APIView): def get(self, request): # Here, I try to retrieve the AWS access key from the session aws_access_key = request.session.get('aws_access_key') if aws_access_key is None: return Response({'status': 'error', 'error': 'No AWS access key found in session.'}) # ... remaining logic ... return Response({'status': 'success', 'bucketsize': bucketsize, 'unit': unit}) In the BucketSize view, request.session.get('aws_access_key') is always returning None, even though I have set it in the LoginVerification view. I have checked the following: The session variable is being set: The code in the LoginVerification view is running without errors. The session has not expired: I'm testing the BucketSize view immediately after the LoginVerification view. … -

Template variable for email in Django allauth socialaccount signup
What template variable does the email field in the form in socialaccount /signup.html in Django allauth use? In the allauth/templates/socialaccount/signup.html there is this form: <form class="signup" id="signup_form" method="post" action="{% url 'socialaccount_signup' %}"> {% csrf_token %} {{ form.as_p }} {% if redirect_field_value %} <input type="hidden" name="{{ redirect_field_name }}" value="{{ redirect_field_value }}" /> {% endif %} <button type="submit">{% trans "Sign Up" %} &raquo;</button> </form> To style the fields and delete labels I want to drop the form and use my own input fields. I can extract the tags inspecting the from in the browser but the value= from the email input field is already populated with my email address and I can't see the variable it uses. Can you help me with it? I tried to find it in the source code but i can't understand it. It seems that it renders the SocialAccount model in the form. I have tried from value="{{ email }}" to value="{{ socialaccount.get_social_account().user.get_email() }}" everything. -

Uploading BLOB from ts through django API to DB
I'm trying to upload some logData but in my database the informationfield is always empty, everything else gets uploaded correctly. I've tried two differnt ways, neither of them seem to work. I uploaded everything packed in a formdata with the logData as blob/string/... nothing worked The other way was creating an Object based on an interface and adding all the information (here aswell i tried string and blob) both didn't work, the field on the Database is always empty. I'm curios if i did something wrong cause the data should be in the database saved as log.csv with the hexstring in it i get the data as an UInt8Array ATM it looks like this: const test = new Blob([locAdjustmentBlob]) const formData = new FormData(); formData.append("log_user", locUser) formData.append("log_adjustment_blob", test) await store.state.apiHandler.postForm("/raw/logs/", formData) And in the the API: class Log(models.Model): log_id = models.AutoField(primary_key=True) log_user = models.CharField(max_length=50) log_adjustment_blob = models.BinaryField() If you need more information just ask Thanks! -

django admin styling is corrupted
I have just started learning Django and when I got to the admin page it appears to be corrupted, no style. I tried collectstatic which gave me an error, I tried to alter static_root but my settings.py does not have it. I tried to reload the page several times with Fn F5 but it did not help. I found some suggestions on the internet but they seem to be a bit too advanced for me, I don't want to make things worse. Is there something not too advanced you could recommend? Thank you! -

Using getStaticProps and getServerSideProps to make authenticated requests to django api
I have a next js application for the frontend and a django REST framework api on the backend. I am using jwt token authentication for my backend using django Simple JWT. Most of my api views are protected by authorization bearer header required. When my user logs in and is authenticated, my django backend responds with an access and refresh token with http only cookies. As I build this app I have a question. If I am making some requests to my backend protected routes with getServerSideProps or getStaticProps which don't run on the client, then is it actually necessary to protect some of my backend routes? If getServerSideProps or getStaticProps dont run on the client, then I don't run the risk of anyone making requests to my backend, considering I have CORS_ALLOWED_ORIGINS in my django settings to only allow requests from my frontend. -

Django does not seem to work with DigitalOcean Spaces
I have followed multiple tutorials on how to use the DigitalOcean object storage known as DigitalOcean Spaces on my Django project but I'm not able to do it. Actually, I was using it before and it was working, after that I moved the static files to Contabo Object Storage, and apparently their CDN is pretty slow so when I decided to go back to DO, it does not work anymore, I even went to the commit where I had it working and copied the exact same code. Here is the code I have on my settings.py: from storages.backends.s3boto3 import S3Boto3Storage class MediaStorage(S3Boto3Storage): bucket_name = "XXXX" class StaticStorage(S3Boto3Storage): bucket_name = "XXXX" DEFAULT_FILE_STORAGE = "nafssi.settings.MediaStorage" STATICFILES_STORAGE = "nafssi.settings.StaticStorage" AWS_ACCESS_KEY_ID = "XXXX" AWS_SECRET_ACCESS_KEY = "XXX/XXXX/XXXXX" AWS_S3_ENDPOINT_URL = "https://XXXX.fra1.digitaloceanspaces.com" AWS_S3_OBJECT_PARAMETERS = { "CacheControl": "max-age=86400", } MEDIA_URL = f"{AWS_S3_ENDPOINT_URL}/media/" STATIC_URL = f"{AWS_S3_ENDPOINT_URL}/static/" When I try python manage.py collectstatic I have the following error: You have requested to collect static files at the destination location as specified in your settings.

Django cannot cast type integer to smallint when attempting to filter a queryset

MySQL server won't connect to PythonAnywhere Django website
Despite all of my efforts, I consistently get this message in the error logs when I try to open my site: django.db.utils.OperationalError: (1045, "Access denied for user '<myusername>'@'10.0.0.116' (using password: YES)"). My database connection code in Django is this: DATABASES = { "default": { 'ENGINE': 'django.db.backends.mysql', 'NAME': '<myusername>$<mydatabasename>', 'USER': '<myusername>', 'PASSWORD': password, #This links to a password variable that was * imported in from another file 'HOST': '<myusername>.mysql.pythonanywhere-services.com', } } I have attempted to change the 'PORT' numerous times. It hasn't worked with a default '3306' port, an empty '' port, or in the current form with excluding the 'PORT' altogether. I have also included the password in the file natively, rather than importing it, but that also changed nothing. I'm very confused here as everything I've seen online appears to state that what I'm doing is correct, but it is still not working. -
Select2 responsiveness with DAL (Django Autocomplete Light) - Width 100% !important not working
It's been a struggle for the past day to me. I've looked everywhere on the internet and can't manage to get it done. I use DAL and initialize widget with URLs. So far so good: sector = django_filters.ModelMultipleChoiceFilter( queryset=Sector.objects.all(), widget=autocomplete.ModelSelect2Multiple( url="sector-autocomplete", attrs={ "data-placeholder": "Secteur", }, ), ) The problem occurs when I resize the page. The select2 items always overflow my container. There seems to be no other items which could be responsible for this overflow. The general recommendation is to set the following css rule: .select2 { width: 100%!important; } It actually feels like it's working when I begin reducing the viewport's width, until a point where the width remains fixed. The css rule on .select2 is actually taken into account, however the computed width seems to still be fixed. <select name="sector" data-placeholder="Secteur" id="id_sector" data-autocomplete-light-language="fr" data-autocomplete-light-url="/sector-autocomplete/" data-autocomplete-light-function="select2" multiple="" data-select2-id="id_sector" tabindex="-1" class="select2-hidden-accessible" aria-hidden="true"> </select> <span class="select2 select2-container select2-container--default" dir="ltr" data-select2-id="6" style="width: 428.5px;"> <span class="selection"> <span class="select2-selection select2-selection--multiple" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="-1" aria-disabled="false"> <ul class="select2-selection__rendered"> <li class="select2-search select2-search--inline"><input class="select2-search__field" type="search" tabindex="0" autocomplete="off" autocorrect="off" autocapitalize="none" spellcheck="false" role="searchbox" aria-autocomplete="list" placeholder="Secteur" style="width: 416.5px;"> </li> </ul> </span> </span> <span class="dropdown-wrapper" aria-hidden="true"> </span> </span> I tried setting the width:100% setting on window resize with Javascript, but … -
How to set HTTP client hints in Django web app?
I would like to set HTTP client hints in a Django web app. I am especially interested in Sec-CH-Prefers-Color-Scheme, which is supported in Chromium browsers to detect the preferred color theme server side. It seems I have to send the browser the hint somehow so that it includes it in the request headers.
