Install Django

Use anaconda to install the Django package in the python environment

Pip install django creates a Django project

Create on the command line using django-admin

Django-admin startproject myproject

Professional version of PyCharm creates django project

Default file

After the project is created, a directory with the same name as the project is generated, as well as a manage.py file

1. Manage.py project management, start the project, create app, data management, this file does not need to be changed

2. In myproject, what we need to write and change are settings.py and urls.py

Urls.py-URL and function correspondence [frequently operated files] settings.py---- project configuration files, such as database connection configuration, static file configuration, APP application configuration, etc., create APP

Large-scale projects generally have many functional divisions. Django will encapsulate these functions in app, that is, without application. Each app has independent functions, static files, etc., and each app does not affect each other.

Python manage.py startapp app

With the above command, you can create an application called app.

Migrations- database changes admin.py- django provides admin background management apps.pymodels.py- for database operations [!! Tests.py- is used to do unit tests. Views.py- defines view functions [! ]

Generally, after creating APP, we need to write views.py function and models.py function, which correspond to URL view function and database operation respectively.

Implement a simple HelloWord web page

First, make sure app is registered.

In the settings.py configuration file, add the app application you created

Write the correspondence between URL and view function

Write correspondence in myproject and view function in views.py of app

App / views.py

From django.shortcuts import renderdef test (request): return render (request,'test.html')

Mypeoject / urls.py

From django.urls import pathfrom app import viewsurlpatterns = [path ('app/test',views.test)]

That is, the test view function corresponding to the app / test route will return a test.html

Start the django project python manage.py runserver 8000

Enter 127.0.0.1:8000/app/test on the web page
