django-filter finds a match if you enter the full name
django-filter finds a match if you enter the full name. For example, I try to filter by the name "Titanic" and I type "Titan" into the search, nothing will be found until I type in the entire text "Titanic". How do I search by partial match? class ProjectFilter(django_filters.FilterSet): address__name = django_filters.CharFilter(field_name='address', lookup_expr='street') approve = django_filters.BooleanFilter(field_name='approve') ordering = django_filters.OrderingFilter(choices=CHOICES, required=True, empty_label=None,) class Meta: model = Project exclude = [field.name for field in Project._meta.fields] order_by_field = 'address' View class FilterTable(SingleTableMixin, FilterView): table_class = TableAll model = Project template_name = "table.html" filterset_class = ProjectFilter -

Django namespacing still produces collision
I have two apps using same names in my django project. After configuring namespacing, I still get collision. For example when I visit localhost:8000/nt/, I get page from the other app. (localhost:8000/se/ points to the right page). I must have missed something. Here is the code: dj_config/urls.py urlpatterns = [ path("se/", include("simplevent.urls", namespace="se")), path("nt/", include("nexttrain.urls", namespace="nt")), # ... ] dj_apps/simplevent/urls.py from . import views app_name = "simplevent" urlpatterns = [ path(route="", view=views.Landing.as_view(), name="landing") ] dj_apps/nexttrain/urls.py from django.urls import path from . import views app_name = "nexttrain" urlpatterns = [ path(route="", view=views.Landing.as_view(), name="landing"), ] dj_config/settings.py INSTALLED_APPS = [ "dj_apps.simplevent.apps.SimpleventConfig", "dj_apps.nexttrain.apps.NexttrainConfig", # ... ] Note that reversing order of apps in INSTALLED_APPS will reverse the problem (/se will point to nexttrain app). -

Django get Keyerror while set permissions in CustomUserAdmin
Hi I am a Python/Django beginner and have a problem with the implementation of a permission thing. I have also copied this from a tutorial, but it doesn't seem to work within my app. What do I want to achieve: It's about the admin module. There I want that only administrators can change the field with the same name. Should only a user or staff user have logged in, this field should be grayed out. with the following code, this also works wonderfully. However, if I then a new user then create / add I get a Keyerror, which also refers to the built-in code.

How properly assign permissions when to user when saving model?
I want to assign Permissions to a user when I Change Group inside the Django admin. I'm adding this permission inside the custom User model in the save method. When I Save changes in the admin panel, no errors are raised, but permissions are not created in my local DB Here is how my model looks like class UserProfile(AbstractUser, PermissionsMixin): name = models.CharField(max_length=255, unique=False, default=None) email = models.EmailField(max_length=50, unique=True) email_verified = models.BooleanField(default=False) date_joined = models.DateTimeField(default=timezone.now) password = models.CharField(max_length=100, null=False) USERNAME_FIELD = "email" REQUIRED_FIELDS = ["name"] objects = CustomAccountManager() def is_member(self, group_name: Roles): return self.groups.filter(name=group_name.value).exists() def save(self, *args, **kwargs): if self.is_member(Roles.STAFF): permissions = Permission.objects.filter(codename__in=settings.STAFF_PERMISSIONS) self.user_permissions.add(*permissions) logger.info(f"Permissions {list(permissions)} added for user {self.email}") super().save(*args, **kwargs) For some reason, I can add permissions from CLI when creating a User instance, but not in the save method, what might be wrong here? -
why records are not being inserted into postgresql database in pytest-django?
I tried to use postgres database with pytest-django and I've encountered a problem. I have a fixture named populate_db which creates some records in the database. To check if pytest actually creates records, I put a 60-seconds sleep after creating the model objects and checked the panel admin but none of the created objects were present there. I think the pytest can't connect to my database and doesn't create any records in the database. Below are the functions that I have in my conftest.py file and I have another test file which tries to retrieve a database record from the API. Here is my code for the populate_db fixture: @pytest.fixture(autouse=True) def populate_db(): sport = Vertical.objects.create(name='sport') bazar = Vertical.objects.create(name='bazar') time.sleep(60) yield -

How to install `distro-info===0.18ubuntu0.18.04.1`?
Trying to modernize an old Django project (2.2), and its requirements.txt (generated via pip freeze) has some lines that make pip install throw fits: distro-info===0.18ubuntu0.18.04.1 I interpreted the errors I got for the first one (see the error output in its entirety at the bottom) as the version string not conforming to PEP-518, but it doesn't even mention the === operator. This SO thread, What are triple equal signs and ubuntu2 in Python pip freeze?, has a similar issue, but: The errors they got is different (ValueError as opposed to my ParseError). The solution was to upgrade pip, but I'm already using the latest one. Now, pip install distro-info works so should I just go with that? update: The project I'm trying to update has been conceived around 2020, and according to the PyPI history of distro-info, it had a 0.10 release in 2013 and a 1.0 in 2021. Could this anything have to do with the weird pip freeze output? (From this PyPI support issue.) The error: ERROR: Exception: Traceback (most recent call last): File "/home/old-django-project/.venv/lib/python3.10/site-packages/pip/_vendor/pkg_resources/__init__.py", line 3021, in _dep_map return self.__dep_map File "/home/old-django-project/.venv/lib/python3.10/site-packages/pip/_vendor/pkg_resources/__init__.py", line 2815, in __getattr__ raise AttributeError(attr) AttributeError: _DistInfoDistribution__dep_map During handling of the above exception, another … -

How to select data from filtered Data to send POST request using ModelViewSet in DRF?

Django, TokenAuthentication, REST Framework API, Authentication credentials were not provided
I'm new to backend. I'm trying to fetch my data in the backend via API token, and I followed this tutorial: https://www.django-rest-framework.org/api-guide/authentication/ When I add these two lines in my View code, I can't fetch my data: authentication_classes = [SessionAuthentication, BasicAuthentication] permission_classes = [IsAuthenticated] The error is { "detail": "Authentication credentials were not provided." } and on my backend I got "GET /hello/ HTTP/1.1" 403 58 But if I delete those two lines, I can fetch my data successfully. This is my View class: `class HelloView(APIView): authentication_classes = [SessionAuthentication, BasicAuthentication] permission_classes = [IsAuthenticated] def get(self, request, format=None): print(request.auth) content = { 'user': str(request.user), 'auth': str(request.auth), } return Response(content)` In the tutorial, it says when I have those two lines, I will be able to view my user name and token in the user router. But I got none for my "auth". However, if I delete those two lines, I can view my "user" and "auth" on my Windows side. Screenshots: backend side, with those two lines frontend side, with those two lines frontend side, without those two lines Could anybody explain this to me please? Any help would be nice!

Django query data in template using JS and python functions
Let's say I have a form for a booking system based on a one-to-many relations with the visitors table..as in the attached image, I'm trying to implement a "Find" function linked to the visitor passport table so we don't need to re-enter the visitors data again. abasically we can enter the passport number and run a query so if his data is there it will come back and fil the form, otherwise we have to reenter it manually using a different form. The following JS function will query the visitor table by passport # and bring back data correctly. However I don't know how to fill out the booking form with the new data so it can be saved, because the data I get is in html format as a table. In my real case, I need to save two fields only from the returned data including the passport number in the booking form, so how I extract the passport # from the returned data, or maybe there is a better way to do so. function visitor_details(pass_num){ url = 'booking_vis_details' $.ajax({ type: "GET", url : url, data: { num: pass_num, csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val() }, success: function(data) { $('#table_details').html(data); } }) } View: … -
