Nested Inline in Django Admin

Question

I have the following scenario where there are three models as follows which should be displayed nested in DJango admin. Am using Django 1.6 release and applied settings as put up in https://github.com/Soaa-/django-nested-inlines

However, it didnt turn up with the expected output. Is there any other solutions to implement nested inlines in Django. I'm a newbie to this framework. Kindly guide me to fix this issue.

model.py

class Project(models.Model):
    name = models.CharField(max_length=200)
    code = models.IntegerField(default=0)
    def __unicode__(self):
        return self.name

class Detail(models.Model):
    project = models.ForeignKey(Project)
    value = models.DecimalField(max_digits=5, decimal_places=2)
    location = models.IntegerField(default=0)

class Configuration(models.Model):
    detail = models.OneToOneField(Detail)
    content1 = models.IntegerField()
    content2 = models.IntegerField()

admin.py

from django.contrib import admin
from nested_inlines.admin import NestedModelAdmin, NestedTabularInline, NestedStackedInline

from myapp.models import Project, Detail, Configuration

class ConfigInline(NestedStackedInline):
    model = Configuration
    extra = 1

class DetailInline(NestedTabularInline):
    model = Detail
    inlines = [ConfigInline,]
    extra = 1

class ProjectAdmin(admin.ModelAdmin):
    inlines = [DetailInline]

admin.site.register(Project, ProjectAdmin)

Answer 1

try https://pypi.python.org/pypi/django-nested-inline .

It has been updated to work with Django 1.6

Answer 2

I believe you've forgotten to set the ProjectAdmin as a NestedModelAdmin:

admin.py :

from django.contrib import admin
from nested_inlines.admin import NestedModelAdmin, NestedTabularInline, NestedStackedInline

from myapp.models import Project, Detail, Configuration

class ConfigInline(NestedStackedInline):
    model = Configuration
    extra = 1

class DetailInline(NestedTabularInline):
    model = Detail
    inlines = [ConfigInline,]
    extra = 1

class ProjectAdmin(NestedModelAdmin):
    inlines = [DetailInline]

admin.site.register(Project, ProjectAdmin)
