Django: How to redirect with arguments

Question

After submit a form, I want to redirect to an specific view passing one flag=True in order to activate a popup like:

def view1(request):
    if request.method == 'POST':
        form = Form(request.POST)
        if form.is_valid():
            form.save()
            return redirect('new_view') # Here I need to send flag=True
    else:
        form = Form()
        return render(request, 'template.html', {'form': form})

How can I do this?

Answer 1

It's not quite clear on what you mean by arguments if it should be in the query string or arguments to a view.

Either way, below is both solutions;

redirect accepts args and kwargs

redirect('new_view', flag='show') # This is the argument of a view

or

redirect('{}?flag=True'.format(reverse('new_view'))

Then you can access it in the view like so

show_flag = bool(request.GET.get('flag', False))

Answer 2

for a given url pattern such as

url(r'^random/(?P<arg1>[0-9]+)/(?P<arg2>[0-9]+)/$', views.random, name="urlname")

or

url(r'^argfree/', views.random2, name="urlname2

from django.http import HttpResponseRedirect
from django.urls import reverse

def view(request):
    # do your thing
    if something:
        return HttpResponseRedirect(reverse("urlname", args=["this_is_arg1", "this_is_arg2"]))
    else:
        return  HttpResponseRedirect(reverse("urlname"))
