I have the Model Admin like this registered on admin site
site.register(Student, ModelAdmin)
Now i have one more admin which is inherited from Model Admin with some custom data like this
class StudentAdmin(ModelAdmin):
    list_display = ('id', 'user', 'created')
    search_fields = ('username',)
which i also want to registered like this
site.register(Student, StudentAdmin)
But then i get the error that Student is already registered
