Introduction to Django Extensions

We know that Django provides different types of services to the user, which extends one of the services that Django provides. Django extensions are nothing but the collection of all custom extensions for the framework; Django extensions include different types of management commands and provide the additional field for database, admin extension, and many more. In the Django project, we have various additional commands that can be used per our requirements. For example, suppose we need to enable the admin app to see ForeignKey or any other; then, we need to add the extension.

What are Django Extensions? Admin Extensions

ForeignKeyAutocompleteAdmin: By using this extension, we can enable the admin app to see the foreignkey whenever we require it. So we need to render this extension with jQuery. With the help of this extension, we overcome the security issues. Autocompletion doesn’t check consent or the mentioned models on the autocompletion view. This can be utilized by clients with admittance to the administrator to uncover information from different models. So if it’s not too much trouble, know and be cautious while utilizing ForeignKeyAutocompleteAdmin. The ongoing adaptation of the ForeignKeyAutocompleteAdmin definitely dislikes late Django forms.

We firmly recommend that the project utilize this expansion refresh to Django 2.0 and the local autocomplete_fields.


Now let’s see the example of admin extension as follows:


from django.contrib import admin from foo.models import sampleaap from django_extensions.admin import ForeignKeyAutocompleteAdmin class sampleadmin(ForeignKeyAutocompleteAdmin): related_search_fields = { 'student': ('stud_name', 'city'), } fields = ('student', ' ', 'is_active'), sampleadmin)


In the above, the student is our foreign key attribute used to search stud_name and city.

Django Extensions Project

Let’s see what the extension of the project is as follows:

Django provides different extensions as follows:

1. Debugger Tags

Using Debugger tags, we can easily debug templates with three types of filters as follows.

IPDB: It is used to debug the model object.

PDB: It is a normal debugger to debug a model object.

WDB: It is a Web Debugger tool.

2. Field Extension

RandomCharField: If we want to create random characters with a specified length, we can use this extension.

JSONFiled: It is used to serialize the JSON objects.

3. Model Extension

ActivatorModel: It is used to check the status of the class. It also provides different extensions to the user, such as validators, command extensions, etc.

Django Extensions Command

Given below are the Django extensions command:

create_app: By using this command, we can create an application with a specified name. By using this command, we can determine the layout choice where you can show a format catalog construction to use as your default.

create_command: Create a command expansion registry structure inside the predetermined application. This makes it simple to get everything rolling by adding an order expansion to your application.

create_jobs: We can create the directory structure as per our specified application.

create_superuser: We can easily make the super user for Django.

describe_form: If we need to display any information for the specified model.

dumpscript: Creates a Python script that will repopulate the information base utilizing objects. The upside of this approach is that it is straightforward and more adaptable than populating the information base or utilizing XML.

export_emails: As per our requirement, we can export the email address in a different format, and it supports Google, outlook, LinkedIn, etc.

generate_secret_key: We can easily create a new secret key.

graph_model: Sometimes, we need to send the output file; at that time, we can use this command to create a graph of our specified model.

password: As per our requirement, we can reset the user password.

print_user_for_session: If we want to print the information or any other data for the specified session key, then we can use this command.

shell_plus: If we enhance the Django shell version, it will auto-load all our models.

show_urls: If we’re going to see the route of URLs in our project, then we can use this command.

sqldiff: By using this command, we can perform sanity testing on a specified database whenever required.

Installing Django Extension

Let’s see how we can install an extension in Django as follows:


$pip install django-extensions


The Django extension is hosted by GitHub; normally, the development version of the Django extension should be stable.

After installing the extension, if we want to check the version of Django, we need to use the below command as follows.


Implementing Django Extension

Let’s see how we can implement the Django extension as follows:

In the above point, we have already discussed how to install the Django extension; after successfully installing it, we need to configure it. So first, we need to create a different environment with the help of the below commands.


mkdir sample_auth cd sample_auth python –m venv env source env/bin/activate pip install django

We need to create an application inside the project, open the setting .py file, and add the created application to the list.

INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'samplapp', 'django_extensions' ] Example of Django Extensions

Let’s consider we have a student model, so add the following code to the


from chúng tôi import models class StudentModel(models.Model): id = models.IntegerField(primary_key=True) stud_name = models.CharField(max_length=20) name = models.TextField() def __str__(self): return f"Student: {self.stud_name}"

Now inside the chúng tôi file, we need to apply for the admin extension.


from .models import * from django_extensions.admin import ForeignKeyAutocompleteAdmin class StudentAdmin(ForeignKeyAutocompleteAdmin): fields = { 'Student':('stud_name',) } fields =('stud_name','remark_text','studnet')

Now run the server and check the admin model as shown below screenshot.
