In Django, How to get the currently running app from within a model on another app? -

basically trying use .get_absolute_url() return dynamic links in relative current app running, in other words reverse model url different url based on app being called.

let me try explain trying example, have 3 apps

• blog (serves shared data layer, contains models post, authors ... etc)
• bloggerway (serves view layer number one, uses blog app models display content in given layout)
• tumblrway (serves view layer, again uses blog app models display content in given layout)

my urls.py files goes like

---------- *project.urls.py* ---------- urlpatterns= [   url('/blogger/', include(bloggerway.urls.py, namespace='blogger'),   url('/tumblr/', include(tumblrway.urls.py, namespace='tumblr'),] ---------- *bloggerway.urls.py* ---------- urlpatterns= [   url('/post/(?p<id>\d+)', blog.as_view(), name='blog'),] ----------  *tumblrway.urls.py* ---------- urlpatterns= [   url('/post/(?p<id>\d+)', blog.as_view(), name='blog'),]

my question is how can define .get_absolute_url() method post model knows app in , return correct url it.

example: if in bloggerway return '/blogger/post' if in tumblrway return '/tumblr/post'

i know can use reverse() function url given named pattern , accepts current_app= argument problem how can running app can pass it.

class post(...):   def get_absolute_url(self):     whoami = ... #get current app here, how!     return reverse('post', current_app=whoami) 

---

solutions want avoid:

• i can inherit post class in both of apps, override .get_absolute_url() there, hardcoding name space of each app in it. use class in app instead of directly using 1 defined model/table.(while offcourse avoid performing migrations class, better define somewhere else models.py)

implement property get_url() class. reverse function should includes "namespace:name" e.g

class post(...):...     def get_blogger_url(self):         return reverse("blogger:post", kwargs={"id":self.id}) # blogger     def get_tumblr_url(self):         return reverse("tumblr:post", kwargs={"id":self.id}) # tumblr
