Is it possible to sub-parametrize pytest parameters values?
I'm working on a DRF (REST API) project and I'm using pytest. Quite often I find myself writing almost identical test parameters and I've been wondering if there's something I'm missing. I haven't read the entire pytest docs, although I definitely did read the entire django docs chapter on tests (not very helpful in my case) and I've now spent a few hours trying to find a solution. Let's assume I have a view like this: from rest_framework import generics from myapp.permissions import IsStaff, IsAdmin class MessagesListView(generics.ListAPIView): permission_classes = [IsStaff | IsAdmin] # ... and for this view I wrote a test: import pytest from rest_framework.reverse import reverse_lazy from pytest_lazy_fixture import lazy_fixture class TestMessagesListViewPermissions: def get_response(self, client): url = reverse_lazy("api:messages-list") return client.get(url) @pytest.mark.parametrize( argnames=["client", "expected_response_status"], argvalues=[ pytest.param( "anonymous_client", status.HTTP_403_FORBIDDEN, ), pytest.param( "authenticated_client", status.HTTP_403_FORBIDDEN, ), pytest.param( "staff_client", status.HTTP_200_OK, ), pytest.param( "admin_client", status.HTTP_200_OK, ), ], ) def test__permissions(self, client, expected_response_status): # WHEN response = self.get_response(client) # THEN assert response.status_code == expected_response_status And there are 4 different client values, but 1+2nd and 3+4th result in the same response status code.

Why Django get result list from query_set too late?
I am studying about Django ORM. I couldn't get an answer from the search, but I'd appreciate it if someone could tell me the related site. My model is as follows. user1 has2 accounts, and 500,000 transactions belong to one of the accounts. class Account(models.Model): class Meta: db_table = 'account' ordering = ['created_at'] user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) account = models.CharField(max_length=20, null=False, blank=False, primary_key=True) balance = models.PositiveBigIntegerField(default=0) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class AccountTransaction(models.Model): class Meta: db_table = 'account_transaction' ordering = ['tran_time'] indexes = [ models.Index(fields=['tran_type', 'tran_time', ]), ] account = models.ForeignKey(Account, on_delete=models.CASCADE) tran_amt = models.PositiveBigIntegerField() balance = models.PositiveBigIntegerField() tran_type = models.CharField(max_length=10, null=False, blank=False) tran_detail = models.CharField(max_length=100, null=True, default="") tran_time = models.DateTimeField(auto_now_add=True) The query time for the above model is as follows. start = time.time() rs = request.user.account_set.all().get(account="0000000010").accounttransaction_set.all() count = rs.count() print('>>all') print(time.time() - start) # 0.028000831604003906 start = time.time() q = Q(tran_time__date__range = ("2000-01-01", "2000-01-03")) rs = request.user.account_set.all().get(account="0000000010").accounttransaction_set.filter(q) print('>>filter') print(time.time() - start) # 0.0019981861114501953 start = time.time() result = list(rs) print('>>offset') print(time.time() - start) # 5.4373579025268555 The result of the query_set is about 3500 in total.

Semgrep: A scalable way of catching all cases in a multiline f-strings
I have some logs in my codebase that have multiline f-strings, such as: ... logger.error( f'...' f'...' f'...' f'...' f'...' f'...' ) And some only have two f'...'s on separate lines while others 3 f'...'s, and so on. I am currently duplicating patterns to catch such logs. For example: ... patterns: - pattern-either: - pattern: | logger.$METHOD( f'...' f'...' f'...' ) - pattern: | logger.$METHOD( f'...' f'...' f'...' f'...' f'...' ) Catch those with 3 and 5 f'...'s on multiple lines. I have to write another pattern for those with 4, 2 and so on. Is there a scalable way to capture all of these with fewer patterns? The current implementation won't scale as there might be logs with 6, 7, 8, 9 and so on multiline f-strings. -
Django orm subquery - in clause without substitution
I need to build a query using Django ORM, that looks like this one in SQL: select * from A where id not in (select a_id from B where ... ) I try to use such code: ids = B.objects.filter(...) a_objects = A.object.exclude(id__in=Subquery(ids.values('a__id'))).all() The problem is that instead of nested select Django generates query that looks like select * from A where id not in (1, 2, 3, 4, 5 ....) where in clause explicitly lists all ids that should be excluded, making result sql unreadable when it is printed into logs. Is it possible to adjst this query, so nested select is used? -

What is the best paradigm for django rest framework unit testing?
I have a Django project (drf) and I want to implement some unit tests for it. I found some different scenarios in implementations. Some of them define a class for each django model containing different methods for CRUD APIs: class FooTestCase(TestCase): def setup(self): pass def test_foo_create(self): pass def test_foo_update(self): pass . . . . Some others define a class for each API view: class FooListCreateTestCase(TestCase): def setup(self): pass def test_foo_create(self): pass class FooRetriveUpdateDeleteTestCase(TestCase): def setup(self): pass def test_foo_update(self): pass and so on ... what is the best paradigm among them? -

Why do I get TypeError when running my Django project with Debug off?
So I've been running my Django project with Debug on, I know it's wrong, and now trying to make the change. But then, the project returned TypeError when I turned the Debug off: TypeError: expected str, bytes or os.PathLike object, not NoneType I tried digging into the issue a little more, and found out that the variable absolute_path of admin/js/jquery.js was None, as you can see in the Traceback below. I've got three clues regarding this issue: It happens in the django-cloudinary-storage library. It probably happened after running python manage.py collectstatic. I did not run this command up until now.. The project ran perfectly with Debug = True. It only happened with Debug=False. What do you think is the problem? Below is a part of my settings.py and full Traceback. settings.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) STATICFILES_STORAGE = 'cloudinary_storage.storage.StaticHashedCloudinaryStorage' STATICFILES_FINDERS = [ 'django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder', ] Full Traceback: Traceback (most recent call last): File "/opt/homebrew/Cellar/python@3.9/3.9.10/Frameworks/Python.framework/Versions/3.9/lib/python3.9/threading.py", line 973, in _bootstrap_inner self.run() File "/opt/homebrew/Cellar/python@3.9/3.9.10/Frameworks/Python.framework/Versions/3.9/lib/python3.9/threading.py", line 910, in run self._target(*self._args, **self._kwargs) File "/Users/ryanoh/Projects/crysenv/lib/python3.9/site-packages/django/utils/autoreload.py", line 64, in wrapper fn(*args, **kwargs) File "/Users/ryanoh/Projects/crysenv/lib/python3.9/site-packages/django/core/management/commands/runserver.py", line 157, in inner_run handler = self.get_handler(*args, **options) File "/Users/ryanoh/Projects/crysenv/lib/python3.9/site-packages/django/contrib/staticfiles/management/commands/runserver.py", line 31, in get_handler handler … -

Unable to POST with ListCreateAPIView
Thank you very much for all your help. We are currently using Django to create a blog with membership features. I would like to allow only members to post articles, but I can't use POST while logged in. When not logged in, POST is available. What is wrong? models.py class Post(models.Model): title = models.CharField(max_length=100, blank=True, default='') content = models.TextField(blank=True, default='') def __str__(self): return self.title class Category(models.Model): name = models.CharField(max_length=100, blank=False, null=True, default='') posts = models.ManyToManyField(Post, related_name='categories', blank=True) class Meta: verbose_name_plural = 'categories' def __str__(self): return self.name serializers.py class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = ['id', 'title','content', 'categories'] class CategorySerializer(serializers.ModelSerializer): name = serializers.CharField(required=False, allow_null=True, allow_blank=True) posts = PostSerializer(many=True, read_only=True) new_posts = serializers.PrimaryKeyRelatedField( queryset=Post.objects.all(), many=True, write_only=True, required=False) class Meta: model = Category fields = ['id', 'name', 'posts', 'new_posts'] def create(self, validated_data): category = Category.objects.create() category.name = validated_data.pop('name', None) new_posts = validated_data.pop('new_posts', None) category.posts.set(new_posts) category.save() return category def update(self, instance, validated_data): instance.name = validated_data.get('name', instance.name) instance.posts.set(validated_data.get('new_posts', instance.posts)) instance.save() return instance views.py class PostList(generics.ListCreateAPIView): queryset = Post.objects.all() serializer_class = serializers.PostSerializer permission_classes = (IsAdmin,) # permission_classes = (AllowAny,) permissions.py class IsAdmin(permissions.IsAdminUser): def has_permission(self, request, view): if request.method in permissions.SAFE_METHODS: role_slug = None if not request.user.is_anonymous and request.user.role is not None: role_slug = request.user.role … -
How does distinct parameter work with the Count method in annotate?
I got a problem with annotate method when I was using the Count method to count multiple columns that come from the database which have a relationship with one of the tables. let me give you a quick example: match_session_instance = MatchSessionInstance.objects.filter(match_session=match_session, status="main") match_instances = MatchSessionInstance.objects.filter(match_session=match_session) action_counts = match_instances.values(player_number=F("player_pk__number"), player_name=F("player_pk__player"))\ .annotate(pass_count=Count("live_match_pass__id", distinct=True), corner_count=Count("live_match_corner__id", distinct=True)) in the meantime I'm not facing any problems I caught my issue and I addressed it but that is the problem now. I don't know How could "disticnt=True" parameter helps me to fix that problem! I googled a bit and found this source that has helped me: Count on multiple fields in Django querysets I know what does distinct as a method in ORM but actually, I get no idea how it works in that format special when I used columns that never have duplicated data. Can anyone help me to understand, please? thanks in advance -
Change reason field (django-simple-history) populated in django admin panel
I use django-simple-history in the project. The documentation https://django-simple-history.readthedocs.io/en/2.7.0/historical_model.html is clear as to how to pass changeReason value while updating the object. I wonder if it is possible to populate history_change_field in django admin panel when making changes? -
Appending all for loop dicts into single list
I just learnt django and I am getting data from api and looping through the json and appending the data into the list. but When I use .map() function in react then the data is appending in list (from for loop) like [ { "results": { "id": 544, "name": "User_1", } }, { "results": { "id": 218, "name": "User_2", } }, { "results": { "id": 8948, "name": "User_3", } }, { "results": { "id": 9, "name": "User_4", } }, ] It is not appending like (Like I want) [ results : [ { "id": 544, "name": "User_1" }, { "id": 218, "name": "User_2" }, { "id": 8948, "name": "User_3" }, { "id": 9, "name": "User_4" } ] ] views.py def extract_view(request): results_list = [] // api url for explanation only get_response = "https://api.punkapi.com/v2/beers" if get_response.status_code == 200: for result in get_response.json(): results_list.append({"results": result}) return Response({"data": results_list}) I know, In for loop it is appending every result within it with every iteration but I also want to assign all the responses within results list. I have tried many times but it is still not working. -
Customizing calendar.HTMLCalendar in a Django Project
