Filtering objects based on many-to-many field in current object
I have a drinks recipe app I'm building that has tags in a many-to-many field that are part of each drink. The tags are a basic taste description. I now want to display 3 similar drinks based on the tag of the current drink. My view looks like this: def drinkdetail_view(request, slug=None): #Grab the correct drink try: obj = DrinkRecipe.objects.get(slug=slug) except: obj = None if obj is None: return HttpResponse("Not found.") context = { "drink": obj, } return render(request,'drinks/drinkdetail.html', context) The model looks like this: class Tag(models.Model): drinkTag = models.CharField(max_length=255, blank=False) def __str__(self): return f"{self.drinkTag}" class TagTaste(models.Model): drinkTagTaste = models.CharField(max_length=255, blank=False) def __str__(self): return f"{self.drinkTagTaste}" class Ingredient(models.Model): ingredientRum = models.ForeignKey('Bottle', on_delete=models.SET_NULL, null=True, blank=True) ingredientName = models.CharField(max_length=255, blank=True) ingredientAmount = models.DecimalField(decimal_places=1,max_digits=5) drink = models.ForeignKey('DrinkRecipe', on_delete=models.CASCADE) def __str__(self): if self.ingredientRum: return f"{self.ingredientRum}" else: return f"{self.ingredientName}" class DrinkRecipe(models.Model): drinkTag = models.ManyToManyField(Tag) drinkTagRum = models.ForeignKey(Bottle, on_delete=models.SET_NULL, null=True) drinkTagTaste = models.ManyToManyField(TagTaste) drinkName = models.CharField(max_length=255, blank=False) drinkDescription = HTMLField() drinkImage = models.ImageField(upload_to=image_upload_handler) drinkActive = models.BooleanField(default=True) slug = models.SlugField(unique=True, blank=True, null=True) imgLocation = 'drinks' def __str__(self): return f"{self.drinkName}" def get_ingredients(self): return self.ingredient_set.all() def get_absolute_url(self): return reverse ('rhumSite:drinkDetail', kwargs={'slug':self.slug}) How do I filter for drinkTag or drinkTagTaste in my view based on the current drink?

Django cant access S3 bucket unless policy completely open to public

Role based access control django like AWS IAM
Recntly I am working on a project where I need to apply role based access control(RBAC) something like AWS IAM. Django already have Groups & permission. I can create a group & add user on that group. Then the user on that group can access to resource. But I've got a problem on that solution. In AWS IAM user can log in to the same account not a different account. How can I implement same feature like aws. I don't want to use account id like aws, user can login with their email/phone & password. Some of my models I use a field created_by with a relation with user. On my views, my queryset something like this MyModel.objects.filter(created_by=request.user). The problem is suppose I give user1 permission to access MyModel. user1 doesn't have any objects created by himself. He need to view the objects that created by the root user. There is also another problem is that the root user isn't belong to any group. I tried using group & permission which provided by django. I also customize the django Group model add a field created_by to track the group owner. But what if the user1 create a group and the … -

Deploying Django in Local Environment
I've built a Django Web App which is running on my local system (127.0.0.1:8000) without any errors. I'm also able to run the same app in my system running "python manage.py runserver xxx.xxx.x.xxx:8000" where "xxx.xxx.x.xxx" is my static IP. Then I connected that IP with my domain (let say "www.some domain name.com"). But the problem is when I try to load the page "www.some domain name.com" I'm not getting anything but when I try to load the page "www.some domain name.com:8000" it's working perfectly. So my question is how to get rid of that port number (i.e., :8000) which is attached to my domain name so that whenever I load "www.some domain name.com" I get exactly same result as "www.some domain name.com:8000". -
Primary-replica architecture for Django testing: non deterministic synchronization issue
I'm using a primary-replica architecture for Django testing. The implementation is pretty straight-forward, as seen here. The thing is that some tests are passing non deterministically: for example, they fail when I run that specifiy TransactionTestCase, but they pass when I run all of them. Then maybe they pass when I run the TranstactionTestCase, but if I run them isolatedly, they fail. The failure reason always is that some object created in the primary database is not found on the replica one. It's hard to understand why, specially considering that both databases are actually just one, according to the documentation provided above. I believe that my setup is correct, and tests do pass sometimes, so sometimes the replication is performed correctly. I just followed the documentation, and expected correct replication between databases. Does any one know what the issue may be? Is there a way to force synchronous replication using Django testing? -

CommonMiddleware is not working in custom middlewares
CommonMiddleware not working in custom middlewares I have a custom middleware like below: class PageNotFoundMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): response = self.get_response(request) sura_pattern = r"/sura/[1-9]\d*-[1-9]\d*/$" print(f'\n\n{request.path_info}: {response.status_code}\n\n') # <-- if response.status_code == 404: if re.match(sura_pattern, request.path_info): return response return render(request, '404.html') elif response.status_code == 400: return render(request, '400.html') elif response.status_code == 500: return render(request, '500.html') elif response.status_code == 200 or response.status_code == 301: return response In the line I marked with arrow: "<--", the request.path_ifo, has no ending "/". example: If the inputted url is: /sura/10, then it shows me /sura/10, but it must append and ending "/" to it. this url is valid, here is the urls.py: urlpatterns = [ path("", home, name="home"), path('sura/<int:sura>/', sura_handler, name='sura_handler'), # <-- path which should get the url path('sura/<str:sura_aya>/', index, name='index'), path('page/<str:page>/', page_handler, name='page_handler'), path('juz/<str:juz>/', juz_handler, name='juz_handler'), path('api/', include('quran.api.urls')), path('sw/', sw, name="sw"), path('manifest/', manifest, name="manifest"), ] Note: Before regex executed, the response.status_code is 404. While if I correctly input the url, (like this: /sura/10/) then the response.status_code in not 404. can someone help me please find out why CommonMiddleware doesn't work in custom middlewares?

I was searching for the question on SO and I found this problem Django settings: DATABASE_URL is not working I tried to do the same but it is not fixing the issue.
