Who?

Django Shelf is meant to be a simple way to categorize your model admins instead of relying on creating new apps for each category.

Bu... but why?

The main reason is simply to avoid creating new apps for each category of model admins. This is especially useful if you got legacy applications that will break if you try to split them into new apps.

Yes, I know that this is not the best practice, but sometimes you just need to do it.

How do I use it?

1. Install the package using pip install django-admin-shelf.
2. Add admin_shelf to your INSTALLED_APPS in your Django settings.
3. Create categories in your admin.py file as follows:

from admin_shelf.admin import Category
from example.models import Model1

custom_category = Category(name="Custom Category")

@custom_category.register(Model1)
class Model1Admin(admin.ModelAdmin):
    pass

A little piece of documentation

The admin_shelf.admin.Category class is used to create categories for your model admins. You can register your model admins to these categories using the @category.register(Model) decorator.

You can set a order for both the categories and the model admins by passing an order argument to the Category class and the @register decorator, respectively.

Example:

from admin_shelf.admin import Category
from example.models import Model1, Model2

custom_category = Category(name="Custom Category", order=1)

@custom_category.register(Model1, order=2)
class Model1Admin(admin.ModelAdmin):
    pass

@custom_category.register(Model2, order=1)
class Model2Admin(admin.ModelAdmin):
    pass

Yes, it is just that simple. You can also use the @register decorator without passing a category, in which case it will be registered to the default category. Or use the default register from django admin if you want to register your model admin without a category.

Translation support

Category(name=...) accepts both plain strings and Django's lazy translation proxies. To localize a category, pass a gettext_lazy value:

from django.utils.translation import gettext_lazy as _
from admin_shelf.admin import Category

shop_category = Category(name=_("Shop"))

@shop_category.register(Product)
class ProductAdmin(admin.ModelAdmin):
    pass

The name is resolved against the active language on every request, so users switching languages see the category label update accordingly.

Recommendation: define each Category once and reuse the same instance across @register calls. Categories are deduplicated by the identity of the name value; two lazy proxies built from the same source string are distinct Python objects and would create separate buckets.
