django存入mysql数据库_Django应用

Django是一个高级的Python Web框架，它鼓励快速开发和干净、实用的设计，Django可以处理数据库、URLs、模板等Web开发中常见的任务，使得开发者可以专注于编写业务逻辑代码，在这篇文章中，我们将介绍如何使用Django将数据存入MySQL数据库。

安装Django和MySQL相关库

我们需要安装Django和MySQL相关的库，在命令行中输入以下命令：

pip install django
pip install mysqlclient

创建Django项目和应用

1、创建一个Django项目：

djangoadmin startproject myproject
cd myproject

2、在项目中创建一个应用：

python manage.py startapp myapp

配置数据库连接

在myproject/settings.py文件中，找到DATABASES设置项，修改为以下内容：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mydatabase',
        'USER': 'myuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}

创建模型

在myapp/models.py文件中，定义一个模型，

from django.db import models
class MyModel(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()
    email = models.EmailField()

生成迁移文件并执行迁移操作

1、生成迁移文件：

python manage.py makemigrations myapp

2、执行迁移操作：

python manage.py migrate

编写视图函数和URL映射

在myapp/views.py文件中，编写一个视图函数，

from django.shortcuts import render, get_object_or_404
from .models import MyModel
from django.http import HttpResponseRedirect
from django.urls import reverse
from django.contrib.auth.decorators import login_required
from django.utils import timezone
