How to categorize in django admin?

Question

I have register my models in admin.py as

admin.site.register(Food_Gallery)
admin.site.register(Gym)
admin.site.register(Gym_Gallery)
admin.site.register(Gym_Pricing_Plans)
admin.site.register(Gym_Programs)
admin.site.register(Trainer)
admin.site.register(Farm)
admin.site.register(Farm_Gallery)
admin.site.register(Farm_Products)

This shows all the models in a single page in django admin

I want to categorize these models into certain categories and display their respective models.How to manage this?

Certain examples as

Food
Gym
Farm

Answer 1

Simply please create a separate App for separate model categories.

You can create app like this (settings.py):

python manage.py startapp food
python manage.py startapp gym
python manage.py startapp farm

INSTALLED_APP += [
   'farm',
   'food',
   'gym',
]

And in admin.py:

admin.site.register(food)
admin.site.register(gym)
admin.site.register(farm)

This is right way.
