Integrating with legacy db in django - django

Question

models.py was created from legacy database.i have created a models.py and created admin.py for app interface and the app name in installed app ,i have around 76 tables (76 classes in models.py).
admin.py:
#! /usr/bin/env python
from django.contrib import admin
from django.db import models
from interface.models import Students,ApplyLeaves
site.register(ApplyLeaves)
site.register(Students)
for m in get_models(db):
site.register(m)
In above case Students and ApplyLeaves classes are not getting registerd in admin interface.
I have placed admin.pyin app directory as well as project directory,still app is not getting registered for administration

Answer 1

If you want to register all models into django admin, you should (although you dont have to) create an instance of the admin.
This is because, although django admin can expose all models based just on the schema alone, it has so many bells and whistels to make that schema representation meaningful real solution.
That said, in your case, you should not keep this admin.py in project level, but just at the application level. Is the Students and ApplyLeaves in the same db database you have passed to the get_models?
The elegant solution to what you are going to do would be as follows:
project-folder/bare_tables.py
from django.db.models import get_models
from django.contrib.admin import AdminSite, ModelAdmin
class BareTables(AdminSite):
pass
new_admin = BareTables(name='bare_tables')
for el in get_models():
new_admin.register(el,ModelAdmin)
In your urls.py
from bare_tables import new_admin
urlpatterns = patterns('',
(r'^bare-tables/', include(new_admin.urls)),
(r'^admin/', include(admin.site.urls)),
That way you can continue to build meaningful interfaces in /admin while you have all tables exposed in /bare-tables.

I have skipped lots of tables cos bored to indent...
`admin.py' you can find in previous post
