nid = models.AutoField(primary_key=True) #自增id(可以不写，默认会有自增id)
title = models.CharField(max_length=32)
publishDdata = models.DateField() #出版日期
author = models.CharField(max_length=32)
price = models.DecimalField(max_digits=5,decimal_places=2) #一共5位，保留两位小数
执行命令创建：（需要记住的！！！）
python3 manage.py makemigrations 创建脚本 python3 manage.py migrate 迁移
具体例子实现
model.py
urls.py
views.py
template /index.html（用来渲染数据的模版）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width">
<title>Title</title>
<link rel="stylesheet" href="/static/bootstrap-3.3.7-dist/css/bootstrap.min.css">
<script src="/static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
<style>
table{
margin-top: 50px;
}
</style>
</head>
<body>
<div class="containers">
<div class="row">
<div class="col-md-9 col-md-offset-2">
<table class="table table-hover">
<thead>
<tr>
<th>编号</th>
<th>书名</th>
<th>出版日期</th>
<th>作者</th>

<th>操作</th>

</thead>
<tbody>
{% for book in book_list %}
<tr>
<td>{{ book.nid }}</td>
<td>{{ book.title }}</td>
<td>{{ book.publishDdata|date:‘Y-m-d‘ }}</td>
<td>{{ book.author }}</td>
<td>{{ book.price }}</td>
<td>
<a href="/del/{{ book.nid }}"><button class="btn btn-danger">删除</button></a>
<a href="/edit/{{ book.nid }}"><button class="btn btn-success">编辑</button></a>
<a href="/add/"><button class="btn btn-primary">添加</button></a>
</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
</div>
</div>
</body>
</html>
五、查看数据库的sql语句（加在settings.py）
查看数据库执行代码
LOGGING = {
‘version‘: 1,
‘disable_existing_loggers‘: False,
‘handlers‘: {
‘console‘:{
‘level‘:‘DEBUG‘,
‘class‘:‘logging.StreamHandler‘,
},
},
‘loggers‘: {
‘django.db.backends‘: {
‘handlers‘: [‘console‘],
‘propagate‘: True,
‘level‘:‘DEBUG‘,
},
}
}
