How To Redirect In Post Request Response

Question

i wanna redirect to success page but it seems i should use different way in post request response.

views.py :

def uploader(request):
    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            return redirect("download",link = 'test')
    else:
        form = UploadFileForm()
    return render(request, 'uploader/pages/upload.html', {'form': form})

def downloader(request,link) :
    return render(request, 'uploader/pages/download.html',)

urls.py :

urlpatterns = [
    re_path(r'^admin/', admin.site.urls),
    re_path(r'^$', views.uploader, name='upload'),
    re_path(r'^(?P<link>[\w-]+)/', views.downloader, name='download'),
]

log in terminal :

[27/Jul/2024 17:43:37] "POST / HTTP/1.1" 302 0
[27/Jul/2024 17:43:37] "GET /test/ HTTP/1.1" 200 46

I've tried HttpResponseRedirect('test') and HttpResponseRedirect(reverse('download', kwargs={'link': 'link'})) to

After correct questions in comments I understand. You use fetch on client-side to made request to back-end per javascript. It is not Django resposibility, but I try to answer.

After fetch request on client-side, you should initiate a programmatic redirect on client-side if you receive a redirect response.

window.location.repelace(response.headers.get('location')) 

But if we read documentation about fetch - we can see, we can do redirect automatically, add in fetch additional attribute:

fetch (url, { method: 'POST', redirect: 'follow'})
