Redirect / return to same (previous) page in Django?

问题

What are the options when you want to return the user to the same page in Django and what are the pros/cons of each?

Methods I know:

HTTP_REFERER
GET parameter containing the previous URL
Session data to store the previous URL

Are there any other?

回答1:

One of the way is using HTTP_REFERER header like as below:

from django.http import HttpResponseRedirect

def someview(request):
   ...
   return HttpResponseRedirect(request.META.get('HTTP_REFERER'))

Not sure of cons of this!

回答2:

While the question and answer is old, I think it's lacking a few options. I have not find any cons with the methods, I would be happy to know if there are any?

request.path_info
request.get_full_path()

request.build_absolute_uri()

from django.shortcuts import redirect

redirect(request.path_info) # No query parameters

redirect(request.build_absolute_uri()) # Keeps query parameters

redirect(request.get_full_path()) # Keeps query parameters

100% working Example

For Class Based View and Function:

from django.http import HttpResponseRedirect
    ...
    return HttpResponseRedirect(request.META.get('HTTP_REFERER'))

from django.http import HttpResponseRedirect
    ...
    return HttpResponseRedirect(self.request.META.get('HTTP_REFERER'))

Example -

class TaskNotificationReadAllView(generic.View):

    def get(self, request, *args, **kwargs):
        TaskNotification.objects.filter(assigned_to=request.user).update(read=True)   
        print(request.META.get('HTTP_REFERER'))    
        return HttpResponseRedirect(request.META.get('HTTP_REFERER'))
