drf-spectacular does not generate parameters in swagger-ui, which I provide in FilterSet class from django_filters
I am trying to implement some API by using GenericViewSet. I have also some FilterSet class with some custom fields. My issue is the generation of these custom fields in swagger-ui endpoint documentation. Generated schema just does not includes all these filtering parameters. Is there any method to solve this problem without using @extend_schema decorator with viewset actions? -

What is the best way to use the permission_classes combination in Django?
Writing 'permission_classes' for DRF project, help me decide what is the best way to write it: The DRF documentation describes two ways to write 'permission_classes': in a tuple and in a list. # first way, in a list permission_classes = [IsAuthenticated & IsUserWithAccess] # or in a tuple permission_classes = (IsAuthenticated, IsUserWithAccess) On one side, python is faster with tuples, but writing 'permission_classes' through a list allows you to use the logical '&' operator. Which do you think is the best way to use from a performance point of view? -
NoReverseMatch - Reverse for 'emotion-buttons' with arguments '(1,)' not found. 1 pattern(s) tried: ['student/emotion\\-buttons$']
I keep getting this error message "NoReverseMatch at /student/take-exam/1 Reverse for 'emotion-buttons' with arguments '(1,)' not found. 1 pattern(s) tried: ['student/emotion\-buttons$']'".

Djanjo with Rest Framework and Postgres search
I need to make search for looking some data from database and this search field should support some logical operations. Like AND, OR, NOT and so on. So I found that Postgres db has something that I need. Ad Django documentation saying to us we need to use SearchQuery with parameter search_type='websearch' And we have something like SearchQuery("'tomato' ('red' OR 'green')", search_type='websearch') # websearch operators When I'm tried to implement to my project I did something like that # views.py class DataSearch(generics.ListAPIView): serializer_class = DataSerializer def get_queryset(self): queryset = Data.objects.all() query = self.request.query_params.get('query') if query is not None: queryset = queryset.filter( search_vector = SearchQuery( query, search_type='websearch' ) ) return queryset But when I'm trying to run it I get Cannot resolve keyword 'search_vector' into field. Choices are: data, foo, foo_id So what I should do to make it work and to make API endpoint for this type of search? -

Bootstrap navbar dropdown not working due to FlexStart css
I know this is a very common issue; however, this one is peculiar. When I use just the regular CSS style sheets (so without style.css), everything works fine, but as soon as I input in main.css, the dropdown stops working. I have no idea which specific part of the CSS is throwing off the dropdown so I am asking for help. I am using Django templates and if I include the style.css on just the home.html page then the dropdown only doesn't work there.

Why Django is not creating Foreign Key constraint on MySQL?
I'm not new to Python nor Django, but this is the first time I'm creating a completely new big project from scratch, and also the first time I'm actually creating the models for the whole database and I'm kinda confused here. Does Django does not really create the ForeignKey constraints on the Database to check if ID exists? It is just a logical python thing that works only when the server is running? Or is it a problem that happens on MySQL? Just to be clear what I'm talking about, the first thing I noticed because as a Laravel developer on PHP side, I'm used to always check the database diagram that PhpStorm/PyCharm generates by connecting to the database, and on Laravel migrated tables, we can see the arrows pointing to the respective foreign key tables relationships, but on the Django created database there is not a single arrow on the database diagram generated by the JetBrains IDE. So I went testing. For example, I have the following models: class Series(models.Model): class Meta: app_label = 'core' db_table = 'km_series' verbose_name_plural = 'series' # added this to avoid plural being "seriess" name = models.CharField(max_length=200) description = models.TextField(default=None, blank=True, null=True) cover_img = … -

In Django, using urlpatterns, how do I match a url-encoded slash character as part of a parameter?
In a Django app — this one — I have a urlpatterns list that looks like this: urlpatterns = [ url(r'^$', schema_view, name='swagger'), url(r'^(?P<page_title>.+)/(?P<rev_id>[0-9]+)/$', WhoColorApiView.as_view(), name='wc_page_title_rev_id'), url(r'^(?P<page_title>.+)/$', WhoColorApiView.as_view(), name='wc_page_title'), ] The second entry will match a path like /en/whocolor/v1.0.0-beta/September_11_attacks/1108730659/?origin=* and the third will match a path like /en/whocolor/v1.0.0-beta/September_11_attacks/?origin=*. The idea is that it's matching a page_title parameter (a Wikipedia article title), and an optional integer rev_id (revision id) parameter. However, it does not work as intended for an article titled "Post-9/11", with path /en/whocolor/v1.0.0-beta/Post-9%2f11/?origin=*. I want this not to match the second pattern (which gets matched as page_title "Post-9" and rev_id 11), and instead match the third pattern. I understand why the second pattern should match if the path is /en/whocolor/v1.0.0-beta/Post-9/11/?origin=*, but when the title is url-encoded as "Post-9%2f11" it still matches the second pattern instead of continuing on to the third pattern. How can I make Django treat the url-encoded slash as part of the parameter instead of a path separator? -
"decouple" could not be resolved
I have uninstalled and reinstalled decouple several times, but my settings.py folder is still saying "decouple" could not be resolved. After uninstalling, I even search for it to make sure it's not hiding somewhere, but it says it's not installed. Then, I reinstall using pip install python-decouple Any idea what else can be done? Here's my settings code: import os from decouple import config from datetime import timedelta from pathlib import Path # Build paths inside the project like this: BASE_DIR / 'subdir'. BASE_DIR = Path(__file__).resolve().parent.parent # Quick-start development settings - unsuitable for production # See https://docs.djangoproject.com/en/4.0/howto/deployment/checklist/ # SECURITY WARNING: keep the secret key used in production secret!
