How to get how many seconds are left before session expiration django
In Django I can set the expiration time for the session request.session.set_expiry(300) and after 5 minutes the session ends. When a user makes a request for a view, I want to be able to check how many seconds are left in the current session before it expires.

Bootstrap 4 modal not working when button clicked from a dropdown

How to fetch the all the data(records) which is searched (like : we are getting a slug from frontend),with Latest updated date
class A: some fields class B: user = models.ForeignKey(User, **CASCADE, related_name='sessions') DEVICES = ( ('android', 'android'), ('ios', 'ios') ) We are creating a dashboard for front end and there is a search field, user supposed to type the device_type and we used to fetch the records who uses only the IOS or Android. In this Case the records is stored in the fields like, Created_at, updated_at, device_type, user_id... we need to apply two filters now here: searched_key : ios or android latest_device_type : only latest updated_record I have done like : User.objects.filter(Q(id=user_details['id']) & Q(sessions__device_type=self.search_key) & Q(reduce(or_, self.query_filter))).order_by('sessions__user_id', '-sessions__created_at').distinct('sessions__user_id'). values('id', 'sessions__device_type', 'first_name') But am not getting exact output : even i tried [0] putting this after order_by and latest() and first() method will fetch only one record so any 1 has the best solution for this. Note : if anybody try to explain with Prefetch please explain with clarity. -
Django's APPEND_SLASH setting does not work with static, why?
Django's 4.1.1 APPEND_SLASH setting automatically appends a slash / until I add static roots, i.e. urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT). For example, this works with http://127.0.0.1:8000/admin and http://127.0.0.1:8000/admin/ urlpatterns = [ path('', home), path('admin/', admin.site.urls), ] However, adding my static roots and the setting no longer takes effect: urlpatterns = [ path('', home), path('admin/', admin.site.urls), ] urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Why? Is this a bug? How is urlpatterns += static etc impacting Django's setting? -

DRF serializer is taking nested JSON payload as single JSON object

I'm trying to update them through one serializer.

But when I try to update both models through this serializer, it returns error saying User has no field named 'doctor_type'. Let's have a look at the JSON i'm trying to send: { "name": "Dr. Strange updated twice", "profile" : { "doctor_type": "PSYCHIATRIST" } } Let's have a look at how the serializer is receiving the JSON: { "name": "Maruf updated trice", "doctor_type": "PSYCHIATRIST" } … -

Delete element with ajax in django
I am currently having some issue in deleting element with ajax in a Django Application. I have some pictures, each of them displayed in a bootstrap card. Basically, my code is kind of working, but I couldn't figure out why, for example, when I display the pictures in the card, in the first one of the list the Delete button doesn't work and, when I have multiple pictures, the delete button works but delete the first picture on the list and not the right one.
