Django：如何在基于 class 的视图中获取登录用户的用户名？

Question

I have implemented a DeleteView and would like it to redirect it to the logged-in user's profile after deleting the object:

class DeleteAttendanceFeedItem(DeleteView, LoginRequiredMixin):
    model = AttendanceFeedItem
    template_name = "users/delete_attendance_feed_item.html"
    context_object_name = "attendance_feed_item"
    success_url = reverse_lazy("user_profile", kwargs={"username" : request.user.username})

I don't have access to the request object in a class-based view, though. Searching StackOverflow suggests I have access to self.request.user.username, but that's throwing the same error.

This seems like a very simple thing that I have burned a surprisingly large amount of time reading SO and Django documentation to absolutely no avail. Help?

Answer 1

Use self.request.user.username to get the username inside the get_success_url() method

class DeleteAttendanceFeedItem(DeleteView, LoginRequiredMixin):
    model = AttendanceFeedItem
    template_name = "users/delete_attendance_feed_item.html"
    context_object_name = "attendance_feed_item"
