[Django]-Nested inlines in the Django admin?

There is now this egg available, which is a collation of the relevant patches mentioned in the other answer:

https://github.com/theatlantic/django-nested-admin

I have done this using https://github.com/theatlantic/django-nested-admin, for the following Data structure:

• Contest
  • Judges
  • Contestants
    • Singers
    • Songs

My admin.pyfile:

from django.contrib import admin
import nested_admin

from .models import Contest, Contestant, Judge, Song, Singer    

class SongInline(nested_admin.NestedTabularInline):
    model = Song
    extra = 0

class SingerInline(nested_admin.NestedTabularInline):
    model = Singer
    extra = 0

class ContestantInline(nested_admin.NestedTabularInline):
    model = Contestant
    inlines = [SongInline, SingerInline]
    extra = 0

class JudgeInline(nested_admin.NestedTabularInline):
    model = Judge
    extra = 0

class ContestAdmin(nested_admin.NestedModelAdmin):
    model = Contest
    inlines = [ContestantInline, JudgeInline]
    extra = 0

admin.site.register(Contest, ContestAdmin)

https://github.com/theatlantic/django-nested-admin appears to be much more actively maintained than the other apps already mentioned (https://github.com/BertrandBordage/django-super-inlines and https://github.com/Soaa-/django-nested-inlines)

I have just ran into this issue as well… Seems this thread which contains the request for the nested inlines feature (https://code.djangoproject.com/ticket/9025#no2) has been updated with further information.

A custom made app called “django-super-inline” has been released. More details here: https://github.com/BertrandBordage/django-super-inlines

Installation and usage instructions below.

Hope this is useful for whomever comes across this.

I ran into a similar issue to this. My approach was to make an UpdateAdmin that held inlines for both Media and Post… it basically just makes it so you have a list of all of the media entries followed by all of the posts in an update.

class MediaInline(admin.StackedInline):
        model = Media

class PostInline(admin.StackedInline):
        model = Post

class PostAdmin(admin.ModelAdmin):
        inlines = [MediaInline,]

class UpdateAdmin(admin.ModelAdmin):
        inlines = [MediaInline,PostInline]

It isn’t an ideal solution but it works for a quick and dirty work around.

Use django-nested-admin which is the best package to do nested inlines.

First, install "django-nested-admin":

pip install django-nested-admin

Then, add "nested_admin" to "INSTALLED_APPS" in "settings.py":

# "settings.py"

INSTALLED_APPS = (
    # ...
    "nested_admin", # Here
)

Then, add "path(‘_nested_ad…" to "urlpatterns" in "urls.py":

# "urls.py"

from django.urls import include, path

urlpatterns = [
    # ...
    path('_nested_admin/', include('nested_admin.urls')), # Here
]

Finally, extend "NestedTabularInline" with "MediaInline()" and "PostInline()" classes and extend "NestedModelAdmin" with "UpdateAdmin()" class in "admin.py" as shown below:

# "admin.py"

from .models import Media, Post, Update
from nested_admin import NestedTabularInline, NestedModelAdmin

class MediaInline(NestedTabularInline):
    model = Media

class PostInline(NestedTabularInline):
    model = Post
    inlines = [MediaInline]

@admin.register(Update)
class UpdateAdmin(NestedModelAdmin):
    inlines = [PostInline]
