How to redirect users to a mobile app in Django view?

Question

I have a Django web application and I'm trying to redirect users to my mobile app in one of the views.

def magic_link(request, token):
    return redirect(f"{settings.FRONTEND_URL}/magic_link/{token}")

This redirect link is like: appname://magic_link/token. However, I'm getting the following error.

DisallowedRedirect at /magic_link/{token}/
Unsafe redirect to URL with protocol 'appname'

How can I fix this issue and redirect users to the mobile app in Django view?

You should create your own HttpResponsePermanentRedirect which inherits from HttpResponsePermanentRedirect by django. In your own class, you add your app scheme to the allow_schemes (something relevant, i can't remember so well) to let django know your app scheme is valid.

Example:

class HttpResponsePermanentRedirect(HttpResponsePermanentRedirect by django):
   allow_schemes=['your_app_scheme',...]
