It seems you’ve encountered a simple yet easily overlooked step. The crucial action is registering a model in the Django admin. This single step instantly makes it visible within the Django interface. 

But there’s no need for disappointment, as you’ve stumbled upon the perfect online resource that comprehensively covers the process of registering a model in the Django admin.

By the end of this guide, you’ll have gained enough experience to smoothly register your models in the Django administration system.

What is Django Admin?

So, let’s get started.

As an illustration, imagine you’re building a blog application on Django with models located in the models.py file.

models.py:

python

Copy code

from django.db import models

from django.contrib.auth import get_user_model

User = get_user_model()

class Author(models.Model):

    User = models.OneToOneField(User, on_delete=models.CASCADE)

    profile_picture = models.ImageField()

    def __str__(self):

        return self.user.username

class Category(models.Model):

    title = models.CharField(max_length=20)

    def __str__(self):

        return self.title

class Post(models.Model):

    title = models.CharField(max_length=50)

    overview = models.TextField()

    timestamp = models.DateTimeField(auto_now_add=True)

    comment_count = models.IntegerField(default=0)

    author = models.ForeignKey(Author, on_delete=models.CASCADE)

    thumbnail = models.ImageField()

    categories = models.ManyToManyField(Category)

    def __str__(self):

        return self.title

Initially, the complexity of this code might seem overwhelming, but allow me to provide a brief explanation of its functionality before delving into the specifics of model registration in the Django interface.

How to Register All Models In Django Admin

If you aim to streamline the process of registering all models in Django, eliminating the need to re-register them across different Django applications within your project, follow these concise instructions.

Start by creating an “admin.py” file within your project directory and structure it as follows:

Next, navigate to the “settings.py” file in the same directory and expand the list of installed applications by adding the newly created folder to it.

settings.py:

python

Copy code

INSTALLED_APPS = [

    ‘django.contrib.admin’,

    ‘django.contrib.auth’,

    ‘django.contrib.contenttypes’,

    ‘django.contrib.sessions’,

    ‘django.contrib.messages’,

    ‘django.contrib.staticfiles’,

    ‘post’,

    ‘blog’  # new (project folder name)

]

Now, insert the following code snippet into the “admin.py” file within your project folder:

admin.py (project folder):

python

Copy code

from django.contrib import admin

from django.apps import apps

all_models = apps.get_models()

for model in all_models:

    try:

        admin.site.register(model)

    except admin.sites.AlreadyRegistered:

        pass

Start the server and take a look at your admin panel. The appearance of the admin interface will match the image that follows.
