Django uses the Django.db module to create a table

1. Create a Django project called Djangodb_demo

2. Create a web-named app under the Djangodb_demo project

3. Create a new models.py file under the Web

From django.db import Modelsclass UserInfo (models. Model): Username = models. Charfield (maxlength=50) password = models. Charfield (MAXLENGTH=50)

At the same time, you need to add the Web to your project in settings.py

The directory structure is

4. Configure the connection database information in the settings.py file of the Djangodb_demo project

DATABASES = {' default ': {' ENGINE ': ' Django.db.backends.mysql ', ' NAME ': Djangodb_demo, ' USER ': ' R Oot ', ' PASSWORD ': ' 123456 ', ' HOST ': ' 10.10.20.134 ', ' PORT ': ',}}

Engine: The type of database you are using

Name:django project in MySQL Library

User: The username of the connection library

5. Build a library called "Djangodb.demo" in MySQL

Note: Django cannot create a library, but can create a table

6. Create a table using Django

You can see that in addition to having a userinfo table in models.py, the others are created by Django itself!

And look at how Django created our userinfo table.
