How to show related objects in Django/Admin?

I have 2 models:

from django.db import models

class Category(models.Model):
    icon = models.ImageField(upload_to = 'thing/icon/')
    image = models.ImageField(upload_to = 'thing/image/')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    title = models.CharField(max_length=200)
    slug = models.SlugField()
    desc = models.TextField(max_length=1000)

    def __str__(self):
        return self.title

    def __unicode__(self):
        return self.title

class Thing(models.Model):
    icon = models.ImageField(upload_to = 'thing/icon/')
    image = models.ImageField(upload_to = 'thing/image/')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    title = models.CharField(max_length=200)
    slug = models.SlugField()
    desc = models.TextField(max_length=1000)
    content = models.TextField()
    category = models.ForeignKey('Category')

    def __str__(self):
        return self.title

    def __unicode__(self):
        return self.title

I am using Django's admin site for basic CRUD operations. I need to show all Things in Category if I am selecting an Category in admin.

Few minutes ago, searching how to solve a similar problem, I finally found a solution.

You actually have to follow @Matteo Scotuzzi answer as well, then

Inside admin.py located in the app your created those models, you have to declare as follows right bellow @Matteo snippet:

admin.site.register(Category, CategoryAdmin)

and that would be enough to make all "Things" appear in "Category" inside your Django Administration respective page which is "Category".

update admin.py file like this.

from django.contrib import admin
from .views import Category, Thing

class CategoryAdmin(admin.ModelAdmin):
    inlines = [
        ThingInline,
    ]

class ThingInline(admin.TabularInline):
    model = Thing

admin.site.register(Category, CategoryAdmin) 
admin.site.register(Thing)

There are two inline options TabularInline and StackedInline

You can use "Inlines" to visualize and edit Things of a certain Category in the admin detail for that category:

In the admin.py file, create an Inline object for Thing (ThingInline) and modify your CategoryAdmin class to have an inline of type ThingInline like this:

...
class ThingInline(admin.TabularInline):
    model = Thing

class CategoryAdmin(admin.ModelAdmin):
    inlines = [
        ThingInline,
    ]
...

For further details, this is the docs for admin inlines: https://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-objects
