Practical combat of background management system in Django framework

Django is a popular web application development framework with a rich set of components and tools that can simplify and accelerate the web application development process. Among them, the background management system in Django is an important component. It provides a powerful management interface that allows us to easily manage the data of our applications, including creation, modification, deletion, query and other operations. It also Provides many extended functionality. In this article, we will introduce how to create a simple backend management system in Django and demonstrate the implementation of several commonly used functions.

1. Create a Django application

First, we need to create a Django application. In the terminal, enter the following command:

$ django-admin startproject myproject
$ cd myproject
$ python manage.py startapp myapp

This will create a Django project named myproject, and an application named myapp.

2. Install Django background management system

To use the Django background management system, we need to install it. In the terminal, enter the following command:

$ pip install django-admin

This will install the latest version of the Django backend management system.

3. Configuring the Django background management system

To enable the Django background management system, we need to make some configurations in the settings.py file in myapp. At the end of the file, add the following:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp',
]

This will enable the Django backend and add it to our application.

4. Create data model

Before using the Django backend management system, we need to create some data models. Create a models.py file in myapp and add the following content:

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()

    def __str__(self):
        return self.name

This will define a Person model, including two fields: name and age.

5. Run the migration

We need to run the following command to enable the new data model:

$ python manage.py makemigrations myapp
$ python manage.py migrate

This will create a new database table to store Person model data.

6. Registering Model

To view and manage the data of the Person model in the Django backend management system, we need to register it as a manageable model. Add the following content to the admin.py file in myapp:

from django.contrib import admin
from myapp.models import Person

admin.site.register(Person)

Now, our Person model has been registered as a manageable model and can be managed in the Django backend management system.

7. Log in to the management interface

Now, we can log in to the Django backend management system using our website administrator account. In the terminal, enter the following command to create an administrator account:

$ python manage.py createsuperuser

Follow the prompts to enter your username, email address, password, and other information. Then, open the following URL in your browser:

http://127.0.0.1:8000/admin/

This will take you to the Django backend management system. Enter the username and password for the administrator account you just created to log in.

8. Test

Now, we can view and manage the data of the Person model in the Django backend management system. Click on the "Persons" link and you will see an empty list. By clicking the "Add person" button you can add a new Person object and save it. You can then return to the Person list to view the added items and use other functions to modify or delete them.

Summary

Django background management system is a very powerful, flexible and easy-to-use technology that can provide rich management functions for our applications. In this article, we demonstrate how to use the backend management system in the Django framework and implement some basic functions. In practical applications, we can customize the backend management interface as needed to provide our administrators and end users with a better user experience and more efficient data management functions.
