As the numbers Models in an app grows, it becomes tedious to find the model we are searching for in a long list on the index page (and navigation bar) of the Django admin
As a part of a new project, I wanted to reorder and logically group models that do not necessarily reflect the apps of the project. I found this little library called [django-modeladmin-reorder](
https://github.com/mishbahr/django-modeladmin-reorder) that does it by remapping the fields with a middleware.
However, I think it would be cleaner if Django supported it natively as this can be useful in almost every project. A layer called AdminApp between the `admin` and the ModelAdmin registered would be the perfect middle ground.
**Proposal**
- Create a new class in admin called `AdminApp`
- The AdminApp should be registerable to admin
- The AdminApp should accept ModelAdmin to be registered with it
- Wire up the ModelAdmins and AdminApps to see custom layout that is not tied to apps
- For all ModelAdmins registered directly to admin, fallback to current implementation
```
class AgencyAdmin(admin.ModelAdmin):
pass
class AgencyConfigAdmin(admin.ModelAdmin):
pass
class AgencyAdminApp(admin.AdminApp):
label = "Agency Details"
class AgentAdmin(admin.ModelAdmin):
pass
admin.register(AgentAdmin) # Existing implementation
# Option 1 : without decorators
## Add Models to AdminApp
AgencyAdminApp.register(AgencyAdmin)
AgencyAdminApp.register(AgencyConfigAdmin)
## Add New AdminApp tp Admin
admin.register_app(AgencyAdminApp)
# Option 2 : with decorators
admin.register(AgencyAdmin, admin_app=AgencyAdminApp)
admin.register(AgencyConfigAdmin, admin_app=AgencyAdminApp)
```
I feel like this seems like a decent middle ground that doesn't break existing implementation but allows the app to be expanded in the future.
So what do you think about the idea? If the core team is interested, I'll be more than willing to work on this but I am first time contributor and will need some mentoring on it.
I've also made a forum post for the same :
