DisallowedRedirect (Unsafe redirect to URL with protocol) Django

In addition to the current answers if you want to redirect to an custom scheme, you can use following code:

class CustomSchemeRedirect(HttpResponsePermanentRedirect):
    allowed_schemes = ['tg']


def redirect(request):
    return CustomSchemeRedirect('tg://resolve?domain=durov')

HttpResponseRedirect.allowed_schemes.append('news')

instead of

return HttpResponseRedirect('news:home',request)

this:

return HttpResponseRedirect(reverse('news:home'))

or

return redirect('news:home')

or

return redirect(reverse('news:home'))
