在运行时从Django添加/删除URL模式

Question

For example I have a url in my urls.py-

url(r'^my-url/$', views.my_view)

Now on a particular action from views, I want to remove this url from urlpatterns and add a new url during runtime. Is it possible, if so, how?

Answer 1

Changing url handler during runtime is not best practice instead you could have the checkpoint in db and handle all the incoming request

models.py

class Version(models.Model):
    version_number = models.IntegerField()
    is_latest = models.BooleanField(default=False)

urls.py

url(r'^handler/(?P<version>\d+)/$', views.handler)

views.py

from django.shortcuts import get_object_or_404

def handler(request, version):
    obj = get_object_or_404(Version, version_number=4)
    if obj.is_latest:
        return render(request,'base.html')
    else:
        return render(request, 'old.html')

Above code authorise only version 4 ( /handler/4 )
