Get started with Django quickly: A simple and easy-to-understand installation tutorial allows you to quickly get started with Django development. Specific code examples are required
In modern web development, Django is a Quite popular Python web framework. It is famous for its simplicity, functionality, efficiency and speed. This article will provide you with a simple and easy-to-understand Django installation tutorial to help you quickly get started with Django development.
Step One: Install Python
First, we need to install Python on our computer. Django is a Python-based framework, so we need to make sure we have the latest version of Python installed on our computer. You can download and install the latest version of Python from the official Python website (https://www.python.org).
When installing Python, please check the "Add Python to PATH" option so that Python can be used directly in the command line.
Step 2: Install Django
After installing Python, we can use Python’s package management tool pip to install Django.
Execute the following command on the command line to install Django:
pip install django
This command will automatically download and install the latest version of Django.
Step 3: Create a Django project
After installing Django, we can use the commands provided by Django to create a new Django project.
Execute the following command in the command line to create a Django project named "myproject":
django-admin startproject myproject
This command will create a folder named "myproject" in the current directory, And generate some files required by Django project in it.
Step 4: Run the Django development server
After creating the Django project, we can view the running status of the project by running the development server provided by Django.
Enter the root directory of the project (i.e. "myproject" folder) on the command line and execute the following command to run the Django development server:
python manage.py runserver
This command will start the Django development server. By default, it listens on the local port 8000. You can view your Django project by visiting http://localhost:8000 in your browser.
After opening this link in the browser, you will see a Django default welcome page, indicating that your Django project has been successfully run.
Step 5: Create a Django application
By default, the Django project only contains an application named "myproject". In order to better organize and manage the project code, we can create a new Django application.
Execute the following command on the command line to create a Django application named "myapp":
python manage.py startapp myapp
This command will create an application named "myapp" in the root directory of the project . At the same time, Django will also generate some initial files for the application, including views, models, and database migration files.
Step 6: Configure routing and views
The core of Django is the URL routing system and view functions. Through the routing system, we can map different URL requests to the corresponding view functions.
In the root directory of the project, open the folder named "myproject" and find the "urls.py" file. In this file we can configure URL routing.
Suppose we want to map the "/hello" request to a view function named "hello", we can add the following code to the "urls.py" file:
from django.urls import path from myapp import views urlpatterns = [ path('hello/', views.hello, name='hello'), ]
In the application's folder, open the file named "views.py" and add the following code to define the "hello" view function:
from django.http import HttpResponse def hello(request): return HttpResponse("Hello, Django!")
Step 7: Run the Django development server and access the views
Now, we have completed a simple Django view. We can run the Django development server and visit "/hello" in the browser to see our view.
Execute the following command in the command line to run the Django development server:
python manage.py runserver
Visit http://localhost:8000/hello in the browser, you will see the output "Hello, Django !", indicating that our view has been successfully rendered.
Through the above simple steps, you have successfully installed and created a simple Django project. You can continue to learn other functions of Django on this basis, such as models, forms, database migration, etc.
I hope the Django installation tutorial provided in this article can help you get started with Django development quickly. I wish you write more powerful Django applications!
