Django - Removing subdomains from my multitenancy app
I have a working multitenancy app in Django with isolated databases that currently uses a subdomain for each tenant and threading. The subdomain prefix is used to make a connection to the corresponding database, so: client1.mysite.com access the database client1 client2.mysite.com access the database client2 And so on. This is the current code I have: middleware: import threading from app.utils import tenant_db_from_the_request Thread_Local = threading.local() class AppMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): db = tenant_db_from_the_request(request) setattr(Thread_Local, 'DB', db) response = self.get_response(request) return response def get_current_db_name(): return getattr(Thread_Local, 'DB', None) utils: def hostname_from_the_request(request): return request.get_host().split(':')[0].lower() def tenant_db_from_the_request(request): hostname = hostname_from_the_request(request) tenants_map = get_tenants_map() return tenants_map.get(hostname) def get_tenants_map(): return dict(Tenants.objects.values_list('subdomain', 'database',)) routers: class AppRouter: def db_for_read(self, model, **hints): return get_current_db_name() def db_for_write(self, model, **hints): return get_current_db_name() def allow_relation(self, *args, **kwargs): return True def allow_syncdb(self, *args, **kwargs): return None def allow_migrate(self, *args, **kwargs): return None Using subdomains is not exactly ideal, so I'm trying to switch the subdomain prefix to a suffix that will be added to the username of each tenant. With that, every tenant will access the same URL: mysite.com And the suffix will be added to the username like that: user@client1 access the database client1 user@client2 … -
how to set up DJANGO_SETTINGS_MODULE with absolute path of the settings.py file
I need to write some scripts for django and trying to set up the DJANGO_SETTINGS_MODULE environment variable at the beginning of each script. The scripts, manage.py and myproject directory are in the same parent directory. Additionally, settings.py file is in myproject directory. Therefore, following code works correctly #test_script_header.py import os os.environ["DJANGO_SETTINGS_MODULE"] = "myproject.settings" import django django.setup() But following code doesn't work #test_script_header.py import os os.environ["DJANGO_SETTINGS_MODULE"] = "/home/<username>/workspace/djangoapp/src/myproject/settings.py" import django django.setup() I get the error ModuleNotFoundError: No module named '/home/<username>/workspace/djangoapp/src/myproject/settings.py' Here is the complete error message Traceback (most recent call last): File "/home/<username>/workspace/djangoapp/src/test_script_header.py", line 22, in <module> django.setup() File "/usr/lib/python3/dist-packages/django/__init__.py", line 19, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "/usr/lib/python3/dist-packages/django/conf/__init__.py", line 82, in __getattr__ self._setup(name) File "/usr/lib/python3/dist-packages/django/conf/__init__.py", line 69, in _setup self._wrapped = Settings(settings_module) File "/usr/lib/python3/dist-packages/django/conf/__init__.py", line 170, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 992, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1004, in _find_and_load_unlocked ModuleNotFoundError: No module named '/home/<username>/workspace/djangoapp/src/myproject/settings' However, I want to eventually move … -

How to add results to a test in Django quiz app?
I'm just learning Django and trying to create a test. I watched the video on YouTube, but I didn't quite understand how to add the test results to the page.

How can I withdraw the points for the answers after sending the answers.I would like the answers to appear on the quiz_detail page.

Graphene django. Get error: String cannot represent value '(value, )' after mutation attempt
I'm new to graphene library and make updating mutation as was in documentation. Also I looked at this video about CRUD : https://youtu.be/C-EfYVXShLE?si=uksgjJEuavU1k9GW I thought, that problem was in mutate arguments, I tried to make it with kwargs, but result was the same. Unfortunatly, most guides was using django-rest to write crud, but I would like to make it without others dependecies. Here's the code: class UpdateAddress(graphene.Mutation): address = graphene.Field(AddressType) class Arguments: address_id = graphene.ID(required=True) index = graphene.String() street = graphene.String() house = graphene.String() flat = graphene.String() locality = graphene.Int() @classmethod def mutate(cls, root, info, address_id, index=None, street=None, house=None, flat=None, locality=None): address = Address.objects.get(pk=address_id) try: entry = Locality.objects.get(pk=locality) except Locality.DoesNotExist: entry = None address.index=index, address.street=street, address.house=house, address.flat=flat, address.locality=entry address.save() return UpdateAddress(address=address) When i try to update some field with this query: mutation { updateAddress( addressId: "1", index: "41204" street: "Shevchenko", house: "1", flat: "15", locality: 1 ) { address{ id, street, index, house, flat, locality{ id } } } } I recieve errors: "errors": [ { "message": "String cannot represent value: ('41204',)", "locations": [ { "line": 12, "column": 7 } ], "path": [ "updateAddress", "address", "index" ] } ], Somehow it sets all string values to a tuple and I … -

Page not found (404) appears when performing tutorial
I get the following error after many tries Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/polls Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: admin/ The current path, polls, didn’t match any of these.

Validation error doesn't render on the template with 2 form
I have in my template with a form in which data is collected in 2 Django forms but sent to the view in the same post like this: <form> {{ form1 }} {{ form2 }} </form> The data is collected in the view and validated. To validate, I have validations declared in both forms. In case the validations fail because the data is incorrect, they return a raise (depending on which one or ones have failed). This raise is what should be shown on the screen to the user as an error. If the failed validation is in the second form, it displays the error correctly and without problems. Now, in the case that the failure is in the first form, the page simply reloads and does not show the error. The data already entered in the form is not lost and can be corrected, but the error is not displayed. My view is something like this: def create(request): form1 = Form1(request.POST or None) form2 = formset_factory(Form2, extra=0) form2Set = form2(request.POST or None, prefix='participant') context = { 'form1': form1, 'form2Set': form2Set, } if request.method == 'POST': if form1.is_valid() and form2Set.is_valid(): # Logic else: context['form1'] = form1 context['form2Set'] = form2Set return … -

I wrote a django model that you can see below, I want to know having the UniqueConstraint is enough for Search and Selecting row base on user and soical type or I need to add the Index for them. if yes what is the different between them becuse base on my search the UniqueConstraint create an Unique Index on DB like posgresql. model: class SocialAccount(Model): """Social account of users""" added_at: datetime = DateTimeField(verbose_name=_("Added At"), auto_now_add=True) user = ForeignKey( to=User, verbose_name=_("User"), db_index=True, related_name="socials", ) type = PositiveSmallIntegerField( verbose_name=_("Type"), choices=SocialAcountType, ) class Meta: constraints = UniqueConstraint( # Unique: Each User Has Only one Social Account per Type fields=( "user", "type", ), name="user_social_unique", ) # TODO: check the UniqueConstraints is enough for index or not indexes = ( Index( # Create Index based on `user`+`type` to scan faster fields=( "user", "type", ), name="user_social_index", ), ) base on the above description I searched but I can't find any proper document to find how django act and we need extra index for them if they are a unique togher already?
