Images is not rendering even after giving the correct directory path in Django. but works when I give incomplete directory
So I have the image that I want to display in my page in a subdirectory 'media'.So I wrote this in my settings.py as recommended everywhere in the internet and documentation: MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR,'media/') And when I load the page I get this error: Not Found: /media/media/slider-1.jpg [09/May/2023 19:31:11] "GET /media/media/slider-1.jpg HTTP/1.1" 404 3943 why the path is media/media in my terminal eventhough the MEDIA_ROOT has only one 'media/' So I just wrote: MEDIA_ROOT = os.path.join(BASE_DIR) and this worked perfectly eventhough the image is not inside the base directory but inside the subdirectory called 'media' I'm curious how is this happening. -
How to remove title of inline object in django admin UI

Django admin searchfield with GenericForeignKey
My Django Foo model has the following GenericForeignKey: content_type = models.ForeignKey(ContentType, blank=True, null=True, on_delete=models.SET_NULL) object_id = models.PositiveIntegerField(blank=True, null=True) my_object = GenericForeignKey('content_type', 'object_id') my_objects can be instances of Baz and (rarely) Qux models. The Qux model has a foreign key to Baz. I want to have a searchfield in my Foo admin page that would search by baz_id and yield either instances of Foo that have the Baz of the given ID in my_object field or instances of Foo that have Qux related to the Baz of the given ID. Here's what I'm trying to do: class FooAdmin(...): # some custom classes and mixins here, neither of which overrides get_search_results() query_fields_placeholders = {'object_id': 'Baz ID'} ... ... search_fields = ('object_id',) def get_search_results(self, request, queryset, search_term): queryset, use_distinct = super().get_search_results(request, queryset, search_term) if search_term: baz_content_type = ContentType.objects.get_for_model(Baz) qux_content_type = ContentType.objects.get_for_model(Qux) baz_queryset = queryset.filter( content_type=baz_content_type, object_id=search_term ) related_qux_ids = Subscription.objects.filter(baz_id=search_term).values_list( 'id', flat=True ) qux_queryset = queryset.filter( content_type=qux_content_type, object_id__in=related_qux_ids ) queryset = baz_queryset | qux_queryset return queryset, use_distinct However, what happens is that only Foo instances that have Baz instances as my_objects are returned by the search and those that have Qux instances in my_object fields seem completely ignored (as if the qux_queryset part … -

JWT How to mock JWT token authentication?
I'm writing unit tests in Django where I have to mock JWT token validation. I used the following code but it throws exception. I suspect the issue is because I'm unable to use decode method because jwt.encode returns a str value which does not have decode method. But in the sample I came across, jwt.encode returns bytes. helper def generate_jwt_token(): client_secret = getattr(settings, "AUTH0_CLIENT_SECRET", None) payload = {'user_id': 1} token = jwt.encode(payload, client_secret, algorithm='HS256') #Commenting the following line because jwt.encode returns str and str does not #have decode method #return token.decode('utf-8') return token Unit test @patch('jwt.decode') def test_post_request_with_valid_data_succeeds(self, mock_decode): payload1 = {'user_id': 1} mock_decode.return_value = payload1 response = self.client.post(self.url, self.dataset, format="multipart", HTTP_AUTHORIZATION=f'Bearer {self.token}') Exception Traceback (most recent call last): File "/usr/local/lib/python3.8/unittest/mock.py", line 1325, in patched return func(*newargs, **newkeywargs) File "/app/apps/datasets/test/test_views.py", line 89, in test_post_request_with_valid_data_succeeds response = self.client.post(self.url, self.dataset, format="multipart", HTTP_AUTHORIZATION=f'Bearer {self.token}') File "/root/.local/lib/python3.8/site-packages/rest_framework/test.py", line 296, in post response = super().post( File "/root/.local/lib/python3.8/site-packages/rest_framework/test.py", line 210, in post return self.generic('POST', path, data, content_type, **extra) File "/root/.local/lib/python3.8/site-packages/rest_framework/test.py", line 234, in generic return super().generic( File "/root/.local/lib/python3.8/site-packages/django/test/client.py", line 473, in generic return self.request(**r) File "/root/.local/lib/python3.8/site-packages/rest_framework/test.py", line 286, in request return super().request(**kwargs) File "/root/.local/lib/python3.8/site-packages/rest_framework/test.py", line 238, in request request = super().request(**kwargs) File "/root/.local/lib/python3.8/site-packages/django/test/client.py", line 719, in … -
Django ORM: This queryset contains a reference to an outer query and may only be used in a subquery
In the queryset, I want to get the average of what subquery returns and then group by 'store_id' and 'avg_sales'.

Migrating 'openapi.Schema()' from drf-yasg to drf-spectacular
I'm migrating from drf-yasg to drf-spectacular, using the From drf-yasg to OpenAPI 3, and I've done most of my docs, but I have some problems triying to replace my old openapi.Schema(). By the docs Schema is not required and can be eliminated. Use a plain dict instead, but I'm not sure how to fit this dict when you have nested objects, for example, my code originaly was: @swagger_auto_schema( operation_summary="Text", operation_description="More text", request_body=openapi.Schema( "body", "Body params", openapi.TYPE_OBJECT, properties={ "params": openapi.Schema( type=openapi.TYPE_ARRAY, items=openapi.Items( type=openapi.TYPE_OBJECT, properties={ "param1": openapi.Schema(type=openapi.TYPE_INTEGER), "param2": openapi.Schema(type=openapi.TYPE_STRING), }, ), ) }, ), responses={ 200: openapi.Response( "Response", openapi.Schema( "response", type=openapi.TYPE_OBJECT, properties={ "status": openapi.Schema(type=openapi.TYPE_STRING, default="ok"), "details": openapi.Schema(type=openapi.TYPE_STRING), }, ), ), }, tags=["example"], I'm not sure how to deal with the type=openapi.TYPE_OBJECT and include the array type (I know about the many=True but again, not how to fit it in the dict). By the docs, it should go something like this? But where I should use the many=True here for the array? request={ "params": { "param1": OpenApiTypes.INT, "param2": OpenApiTypes.STR, } }, -

Django JSONField with arrays filtering by substring
I've got a events JSONField in my model and I want to filter by value on key. Example object creation: MyModel.objects.create( name="test", events=[ {"type": "created", "info": "xxx"}, {"type": "sent", "info": "abc"}, ] ) So in events I have a list of events with same keys but different value. I want to filter by name and info values for doing autocompletion feature - so I need to filter by string icontains in info. What I figured out is MyModel.objects.filter(Q(name__icontains='abc') | Q(events__info__0__icontains='abc')) but it takes only first event from a list - if info match in second element then it is not placed in results. Is it possible to do with django orm? I want something like MyModel.objects.filter(Q(name__icontains='abc') | Q(events__info__<all>__icontains='abc')) -
Django: How to automatically restart gunicorn after my code changed
I'm developing a Django website, in which top menu should reflect changes in the page structure. In some sections (such as "About") changes are rare, so the menu is kept as a separate HTML file, which is included into the base template base.html: {% include "includes/menu_about.html" %} Although this works, there is a problem: the server doesn´t "see" that my menu_about.html file has changed, and, apparently, shows the page from cash, so the user doesn´t see the updated menu until I manually restart Gunicorn server. How is it possible to solve this problem? Looks like I have to make Gunicorn to restart automatically each time after my "Page" model saved. Perhaps, there is certain command in Django, which can be run on model save and restart the Gunicorn? Or may be certain settings in the Gunicorn itself? -
Update a field for all instances when a Many-to-many relationship is involved
I have the following: class Customer(model): stores = models.ManyToManyField(Store, related_name = "customers") subscriptions = models.ManyToManyField(Subscription, through = "CustomerSubscription") class CustomerSubscription(model): subscription = models.ForeignKey(Subscription) customer = models.ForeignKey(Customer) class Subscription(model): is_valid = models.BooleanField() For a given store instance: store = Store.objects.get(pk=1) I want to get all the subscriptions for all the customers and set is_valid to False. This is my attempt which appears to work: customers = store.customers.all() for c in customers: c.subscriptions.update(is_valid=False) I then tried using prefect_related: customers = store.customers.prefect_related("subscriptions") for c in customers: c.subscriptions.update(is_valid=False) But I don't believe I am doing this correctly as it resulted in more sql queries than my first attempt. How should I be doing this? -

Django OneToOne field where one side of the relation is mandatory
Suppose I have these models: class Space(models.Model): item = models.OneToOneField(Item, null=True, on_delete=models.CASCADE) class Item(models.model): ... A Space can contain an Item, but it can be empty too. On the other hand, every Item must have a Space. It cannot exist in a void. I could create a field .space in my Item model (with null=False), but then Space.container can never be empty (raising a RelatedObjectDoesNotExist exception when creating/querying them). Handling these exceptions is cumbersome. I'd rather have Space.container return None (as is the case with my current setup). Is there an easy way to make .space in the Item model mandatory, but not the other way around? -
How to set the redirect URL in Django within the dispatch method with URL parameters
I have a custom Mixin that checks for the total usage of a particular service and based on that allows users to submit the form or redirect to the success_url with an error message of total usage. This works fine for URLs without any dynamic parameters like pk or slug. but with parameters, Django cannot find a URL pattern to redirect to the success_url. urls.py (URL file of Instagram app) # some other urls path('<int:post_id>/image/stock/', InstagramImageStockView.as_view() , name='instagram_image_stock'), path('<int:post_id>/image/stock/generate/', InstagramGenerateStockImageView.as_view(), name='instagram_fetch_stock_image'), # more URLs views.py class InstagramGenerateStockImageView(CustomMixin, FormView): form_class = InstagramStockImageForm success_url = 'instagram:instagram_image_stock' # other code custom mixin class CustomMixin: # other methods def check_generation_status_and_redirect(self, request, *args, **kwargs): if self.able_to_generate: return super().dispatch(request, *args, **kwargs) else: # Set an error message based on conditions. return redirect(self.success_url, kwargs=kwargs) def dispatch(self, request, *args, **kwargs): self.check_daily_count() return self.check_generation_status_and_redirect(request, *args, **kwargs) When a user reaches the limit I am getting NoReverseMatch error while redirecting to the success_url. I also tried by defining the success_url with reverse_lazy but not working. Thanks. -
how can I determine which ORM is the most suitable for my specific Django project requirements?
What are the factors to consider when choosing an ORM for a Django project, and how can I determine which ORM is the most suitable for my specific project requirements? I'm currently working on a new project and I'm looking for advice on the best ORM to use that doesn't require migration. I prefer to work with ORMs that simplify database interactions and reduce the amount of boilerplate code that I have to write. However, I've run into issues with ORMs that require migration for database schema changes. I'm hoping that some of you may have experience with ORMs that don't require migration and can offer recommendations. I'm particularly interested in ORMs that have a robust set of features, good documentation and are easy to use. Any suggestions would be greatly appreciated. Thank you in advance! -
