Building an Admin Panel with Django Admin in 2021

Building an Admin Panel with Django Admin in 2021

Admin panels are at the heart of every business operation, be it sales, analytics, user management, and so much more. That said, it isn't easy to find the right tools to help you build robust and scalable systems without spending too much time.

Django admin has been the go-to solution for many developers over the years. It provides a fast, easy-to-use, and highly maintainable framework for building full-stack applications and admin dashboards. These reasons make it a great choice to build admin panels.

To show you how to build admin panels with Django, we will build a dashboard for moderators to manage business reviews. All of this will be built on Postgres and the Public Yelp dataset.

Here’s a sneak peek of what we’ll be building:

Awesome right? Let’s get started!

Setting up a project

We start by setting up a project. A project is a collection of settings for an instance of Django, which includes a database and app configuration. A project may contain multiple apps, but we are only going to need just one.

To set up a project for our Yelp review dashboard, use your terminal and cd into a directory where you’d like to store the project and run the below command:

django-admin startproject yelp

When that’s done, cd into the yelp directory that was created and start up the server by running the command below:

python manage.py runserver
The server automatically watches the project for changes, so you don’t need to restart it manually

Creating an app

In Django, you can have multiple apps inside a project. This means that apps are modular and can be used in multiple projects.

Go ahead and create a reviews app that will hold the code for the dashboard by running the below command:

python manage.py startapp reviews

You’ll notice that a reviews directory has been created with a couple of files. This is where all the code will go.

Registering the app and database

Next, we’ll need to let Django know about the reviews app we just created. We do this by registering the app.

To register the app, open yelp/settings.py file and add reviews.apps.ReviewsConfig to the INSTALLED_APPS list. After adding this, INSTALLED_APPS should look like this:


When that’s done, move on to configure your database connection in the DATABASES dictionary:

    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'your_database',
        'USER': 'your_database_user',
        'PASSWORD': 'your_database_password',
        'HOST': '',
        'PORT': '5432',


Save the changes and run the below command so that Django can set up tables in the database for the app in the INSTALLED_APPS list:

python manage.py migrate

The last thing that needs to be done here is to modify the path of the admin dashboard in the yelp/urls.py file so that it is mounted on the root path instead of /admin. Update the urlpatterns list to:

python manage.py migrate

Creating models

With everything set up, we can continue with creating modes that describe the database layout. Models also show relationships between tables and can be used to specify validation and the widgets that Django will create for the dashboard UI.

We are going to need three models: one for businesses, users, and reviews. To create these, head to reviews/models.py and paste the below code:

from django.db import models

# Model for Businesses
class Business(models.Model):
    id = models.CharField(primary_key=True, max_length=100)
    name = models.CharField(max_length=100)
    address = models.CharField(max_length=100, null=True)
    city = models.CharField(max_length=100)
    state = models.CharField(max_length=100)
    stars = models.FloatField()
    categories = models.TextField(null=True)

    def __str__(self):
        return self.name

# Model for Users
class User(models.Model):
    id = models.CharField(primary_key=True, max_length=100)
    name = models.CharField(max_length=100)
    yelping_since = models.DateTimeField()

    def __str__(self):
        return self.name

# Options of the select widget on the UI
status_choice = (('approved', 'APPROVED'), ('pending',
                 'PENDING'), ('rejected', 'REJECTED'))

# Model for Reviews
class Review(models.Model):
    id = models.CharField(primary_key=True, max_length=100)
    status = models.CharField(
        max_length=10, choices=status_choice, default='pending')
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    business = models.ForeignKey(Business, on_delete=models.CASCADE)
    stars = models.IntegerField()
    text = models.TextField()
    date = models.DateTimeField()

    def __str__(self):
        return self.user.name

You’ll notice that each class represents a model of a table in the database. Each model has variables that represent the fields. The fields are annotated with their respective field types and validation/relationship where necessary.

Now let’s create migrations for these models. Run the below command to do this:

python manage.py makemigrations reviews

Then apply the migrations

python manage.py migrate

Taking a look at the database, you’ll notice that tables for reviews_business, reviews_user, and reviews_review have been created. At this point, you can import the yelp dataset.

Download the public Yelp dataset and import it into the reviews_business, reviews_user, and reviews_review tables respectively.

Taking the app for a spin

Are we ready to take the app for a spin? Not so fast. You’ll need to create an admin user to be able to view the site.

To create an admin user, run the following command and answer the prompt:

python manage.py createsuperuser

Once that’s done, start the server(if you previously closed it) and visit

python manage.py runserver

After logging in, you’ll notice that none of the models we created is showing up. Let’s fix this in the next section.

Displaying the reviews app

To make the models from the reviews app visible in the admin panel, you’ll need to register them in the reviews/admin.py file.

This is quite easy to do. Add the below code to your reviews/admin.py file:

from django.contrib import admin

from .models import Business, Review


Save the file and head back to the browser. Upon reloading, you should now see Business under the Review app.

Easy as pie, right?

Play around with the dashboard to see the power of Django. But you’ll notice that the way data is displayed a little off, and we can’t see reviews for each business. Django gives us the room to improve user experience, so let’s do that.

Customizing the dashboard

We can make the reviews dashboard much better by adding some options to customize it.

Head to the reviews/admin.py and replace its content with the below code:

from django.contrib import admin
from .models import Business, Review

# A class that displays Reviews in a table form
class ReviewInline(admin.TabularInline):
    model = Review

    # Don't add any extra blank form for new Reviews
    extra = 0

# A class that lets us customize the Business list
class BusinessAdmin(admin.ModelAdmin):
    # Embed reviews in related businesses
    inlines = [ReviewInline]

    # Show the below properties in the Business list
    list_display = ('name', 'city', 'stars', 'categories')

    # Add filters for state and stars
    list_filter = ['stars', 'state']

    # Make the Business list searchable by name
    search_fields = ['name']

    # We don't want ids showing up
    exclude = ('id',)

admin.site.register(Business, BusinessAdmin)

Save the file and head to your browser. You’ll immediately notice that you have a much better dashboard experience.

We can further make the dashboard cleaner by removing the annoying AUTHENTICATION AND AUTHORIZATION app that shows up by default.

To do this, add these lines to your reviews/admin.py file:

# Add this to the top of your file
from django.contrib.auth.models import Group, User

# …previous code goes here

# Add this to the bottom of your file

Save the file and reload your browser. Now we have a super clean functional Django reviews dashboard.

Now that the application is fully built, you can play around with it. This dashboard makes it easy for moderators to search for a business and approve reviews made by users.

Here’s everything in action:

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!


How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
