Django - ImportError at /graphql
Well, I tried to start GraphQL on Django's local server. But got a mistake that: You need to pass a valid Django Model in UserType.Meta, received "auth.User". Exception value is: Exception Value: You need to pass a valid Django Model in UserType.Meta, received "auth.User". To be honest, I don't really understand where I can find 'UserType.Meta. The model about users looks like: # user - связь с пользователем один-к-одному # website - юрл, по которому можно больше узнать о пользователе # bio - о себе (Капитан Очевидность) class Profile(models.Model): user = models.OneToOneField( settings.AUTH_USER_MODEL, on_delete=models.PROTECT, ) website = models.URLField(blank=True) bio = models.CharField(max_length=240, blank=True) # __str__ - более удобное отобажение в админке def __str__(self): return self.user.name So, what can I do to solve this problem? -

How to replicate Rails `timestamps` in Django
In Rails migrations I can call a function called timestamps in a migration when creating a table to add created_at and updated_at fields to the table. I can do this in django by creating a new abstract model class TimestampedModel(models.Model): created_at = models.DateTimeField(auto_now_add=True, null=False, blank=False) updated_at = models.DateTimeField(auto_now=True, null=False, blank=False) class Meta: abstract = True and then in my model just inheriting from TimestampedModel. But I'm not a massive fan of inheritance and I'd rather have some function timestamps that I can add to my model like: class UserModel(models.Model): timestamps() Is this possible in django? If it is, it seems like a useful technique in general, but unfortunately hard to google for. Thanks! -

Async long running functions in Django REST framework
Using Django REST Framework (DRF) one API I'm implementing kicks of a function that can take a while. Callers don't have to know the result ('fire and forget') so they could have an immediate response. Django has async views now and that would solve the problem by calling the long running function asynchronously. But DRF doesn't have async support at the moment. Other suggestions I've seen is using Celery but that is a big step in both code and infrastructure. What is the easiest way to spawn the long running function in a sepate process? I must say that this long running process does need access to the ORM. I'm extending ModelViewSet: class myViewSet(viewsets.ModelViewSet): def update(self, request, *args, **kwargs): # This should be async ('fire and forget') long_running_function() -
Why images on Cloudinary don't appear?
I'm trying to implement cloudinary storage in my django project. Images are loaded successfully to cloudinary but when I create a post with image, images don't appear. Here is a URL of one image https://res.cloudinary.com/dewqgxp2a/image/upload/v1/media/images/posts/2021/07/slide02_CO2UtgA.jpeg As you see it, images are uploaded on Cloudinary but it's impossible to access the images. So when the browser tries to access that image it fails and image doesn't appear. How can solve it please? I need really your help! Here are configs in my settings.py INSTALLED_APPS: [ ... 'django.contrib.staticfiles', 'cloudinary_storage', 'cloudinary', ] # Cloudinary storage configs CLOUDINARY_STORAGE = { 'CLOUD_NAME': 'cloud name', 'API_KEY' : 'cloud key', 'API_SECRET' : 'api secret', 'SECURE' : True, } DEFAULT_FILE_STORAGE = 'cloudinary_storage.storage.MediaCloudinaryStorage' For security reasons, I replaced cloudinary configs by texts. Could anyone help me please? -
How to write secure rules for firebase when using custom authentication?
I am building an app with django and firebase. I have built my custom authentication system. And I need secure rules so that only people whom I have authenticated can read/write in the database or storage. { "rules": { ".read": true, ".write": true } } These are my current rules, so is their a way to pass a token when I request(read or write on databse) which is first checked. Something like -> { "rules": { ".write": "isAuthorized == true", ".read": "isAuthorized == true" } } And when making request to database like- db.child('test').get() I pass this isAuthorized bool Any help is appreciated, or you can suggest changes. -

Django - static files are not found in root static folder, but settings point to it
I'm starting to configure my first Django project and I find this issue which is really bothering me. I have set a root static folder to put some css files for my base template there, but Django is not finding any css files there. My settings.py are like this: ... BASE_DIR = Path(__file__).resolve().parent.parent ... STATIC_URL = '/static/' SATICFILES_DIRS = [ BASE_DIR / 'static', BASE_DIR / 'sales' / 'static' ] MEDIA_URL = '/media/' MEDIA_ROOT = BASE_DIR / 'media' ... ... And in my urls.py I have: urlpatterns = [ path('admin/', admin.site.urls), path('', include('sales.urls', namespace='sales')), ] urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT, show_indexes=True) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT, show_indexes=True) ... If a run findstatic I get the following: $ python manage.py findstatic --verbosity 2 static No matching file found for 'static'. Looking in the following locations: /home/dancab/git/django-3-course/myenv/lib/python3.9/site-packages/django/contrib/admin/static /home/dancab/git/django-3-course/src/sales/static And also, in the browser, I can see the list of files in the MEDIA folder, but I can't see the STATIC folder, I get the following error: I don't understand why I Django finds the MEDIA folder and not the STATIC folder. Thanks in advance to anyone that gives me a hint on why this happens. -
Django cronjob is still running even after deletion
In one of my past project developed in Django python framework, I needed a cronjob to automate some process. I used this django-cron module and installed it as per their documentation. Everything was working as usual. Recently, the project was discontinued and every code and related processes were removed. But I found that the cronjob related to that project is still running. I double checked with crontab -e, the cronjob is not there. I tried by reloading and restarting the cron daemon, even I restart the whole server, but in vain. If I check in /var/log/syslog, I still can see the cron is running every minute. Here is the output from syslog. Jul 25 08:33:01 CRON[26412]: (ubuntu) CMD (cd /home/projects/pdf-generator && /home/venv/django/bin/python manage.py runcrons core.myapp.crons.PdfConversionCronJob) The server is running Ubuntu 18.04. Does anyone know what is going on and how to remove the cronjob for once and all? -

How to get fully randomised serialisation data from Django filter
I have the following serialization and intend to get query data fully randomized. class RecommendationList(generics.ListAPIView): model = Obj serializer_class = RecommendationFilterSerializer filter_backends = [filters.SearchFilter] search_fields = ['uuid', ] pagination_class = StandardResultsSetPagination def get_queryset(self): uuid = self.request.query_params.get('uuid') Obj.objects.filter(user=Obj_list[0].user) .filter(Q(status=Obj.Status.PUBLISHED)) .filter(Q(privacy=Obj.Privacy.PUBLIC)) .order_by('uploaded_at').reverse() return Obj.objects.filter(Q(status=Obj.Status.PUBLISHED) & Q(approved=True)) .filter(Q(privacy=Obj.Privacy.PUBLIC)) .order_by('?') There are suggestions for results returning two rows : import random last = MyModel.objects.count() - 1 index1 = random.randint(0, last) # Here's one simple way to keep even distribution for # index2 while still gauranteeing not to match index1. index2 = random.randint(0, last - 1) if index2 == index1: index2 = last # This syntax will generate "OFFSET=indexN LIMIT=1" queries # so each returns a single record with no extraneous data. MyObj1 = MyModel.objects.all()[index1] MyObj2 = MyModel.objects.all()[index2] However, the size of table rows is more than 10000, and while serializing the request might need to access all 10000 items. Fulfilling this requirement and regarding the size of the table ORDER_BY('?') becomes a very costly operation, hence I cannot use the following. Any suggestions on this? -

After initial setup and migrations, when I test the usual python manage.py runserver 0.0.0.0:8000 it works well (showing all images and grabbing all static files) with no errors. When I test gunicorn --bind 0.0.0.0:8000 myproject.wsgi, no static files are grabbed (anyway, I understand that's Nginx's job) but this error appears for every static file requested in the page: Internal Server Error: /static/img/logo.png Traceback (most recent call last): (...) File "/usr/lib/python3.8/posixpath.py", line 76, in join a = os.fspath(a) TypeError: expected str, bytes or os.PathLike object, not list I suspect this is related to settings.py, where STATICFILES_DIRS are declared as a list, according to Django: STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') This doesn't look to me related to collectstatic (but it could be). Why is it that there is no error in the Django server and when Gunicorn is used suddenly the list of paths is a problem?
