Question

Another question like this one was asked, but I don’t ‘like’ the answer (in reality it didn’t really answer the question in the first place): Can any one explain how can i pass arg or kwargs from redirect to another view?)

I have a view and need to redirect to another view (in another application) and still send an argument along. Currently I have:

return redirect('/projects/', login_error=error)

Which doesn’t work (the redirect happens but the argument doesn’t go through). Is it even possible to do this using redirect()? The documentation doesn’t have anything on it.

However, I also tried referring to the view without using a URL:

return redirect('projects.views.list_all', login_error=error)

But that doesn’t work either.

Answer 1

redirect returns an HTTP redirect to the supplied URL – that is, the browser receives a
30x response and initiates a new request.

To preserve state between the two requests, you either need to set a session variable (as per the other answer) or provide a query parameter, eg:

return redirect('/projects/?login_error=error')

You will then need to process the incoming request.GET parameter in the other view.
