一、准备下载
python3.6.6 https://www.python.org/downloads/windows/（需要注意你的电脑是32位还是64位）
mysql 5.1.72 https://dev.mysql.com/downloads/mysql/
pip 18.0 https://pypi.org/project/pip/
Django 1.11.7 https://www.djangoproject.com/download/ 或者用pip install django=18.0（注意如果是2.0的话，会出错的）
pymysql 0.9.0 pip3 install PyMySQL
软件pycharm http://www.jetbrains.com/pycharm/
二、创建项目
1.开始创建项目
文件----新项目---django
点击执行，然后在浏览器中输入127.0.0.1:8000可以看到html页面
项目：pythonweb_demo app名称：pythonweb
2.项目中文件代码
python_demo/python_demo/seeting.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'pythonweb' //添加你的app的名字
]
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',//采用mysql
'NAME': 'appdata',//你的
'USER': 'root',//登录库用户名
'PASSWORD': '123456',//密码
'HOST': '',//主机
'PORT': '3306',//端口 注意用这个端口号，注意拼写 其他的应该没问题
'OPTIONS': {'isolation_level': None}//链接数据库需要填写这个
},
}
STATIC_URL = '/static/'
STATICFILES_DIRS = [
(
os.path.join(BASE_DIR, "static")
)
]
python_demo/python_demo/urls.py
from django.contrib import admin
from pythonweb import views
from django.conf.urls import url
urlpatterns = [
url('admin/', admin.site.urls),
url('views/', views.index)
]
python_demo/pythonweb/models.py
from django.db import models
# -*- coding: utf-8 -*-
# Create your models here.
class Mobile(models.Model):
brand = models.IntegerField()
size = models.FloatField()
price = models.IntegerField()
# age = models.IntegerField()
print(brand)
def __unicode__(self):
# 在Python3中使用 def __str__(self)
return self
python_demo/pythonweb/views.py
from django.shortcuts import render
from pythonweb.models import Mobile
# Create your views here.
def index(request):
print(1)
str = Mobile.objects.all()
return render(request, 'index.html', {'str': str})
python_demo/templates/index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>后台主页面</title>
</head>
<body>
<div class="home">
姓名为name1的年龄为:{{ str.price }}
{% for str in str %}
<p>{{str.brand}}   :   {{str.price}}</p>
<br>
{% endfor %}
<h3>这是home页面</h3>
</div>
<script src="/static/jqueryHome.js"></script>
</body>
</html>
三、开始创建数据库
1.开始链接数据库，在cmd中打开python,执行命令
python manage.py makemigrations pythonweb
python manage.py migrate pythonweb
这样就可以在数据库中创modle.py中对应表
2.在cmd中打开mysql，查看表是否创建成功
mysql>show databases;//查看数据库
mysql>use appdata;//进入数据库
mysql>show tables;//崭新当前数据库中表
mysql>desc mobile;//展示表中的参数
mysql> SELECT * FROM appdata.pythonweb_mobile m;//展示表中数据 mobile是表 python_web是你的app的名字 自动添加的
mysql> insert into pythonweb_mobile(brand,size,price) values;//添加数据
mysql>SELECT * FROM appdata.pythonweb_mobile m;//展示数据是否添加成功
3.在pyCharm执行
4.在浏览器中打开127.0.0.1
四、资料

https://blog.csdn.net/pugongying1988/article/details/72870264 field
五、错误：
1.Your STATICFILES_DIRS setting is not a tuple or list; "
ImproperlyConfigured: Your STATICFILES_DIRS setting is not a tuple or list; perhaps you forgot a trailing comma?
解决方案：
找到settings.py文件，
把STATICFILES_DIRS=(os.path.join(BASE_DIR,'static'))
改为STATICFILES_DIRS=[(os.path.join(BASE_DIR,'static'))]
2.安装mysqlclient出现错误： install --record C:UsersadminAppDataLocalTemppip-record-2fiij4o6install-record.txt --single-version-externally-managed --compile" failed with error
python==3.6
3.django连接mysql
https://blog.csdn.net/liuweiyuxiang/article/details/71101910
4.错误django.db.utils.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED' at line 1"）
解决：setting.py--->DATABASES 添加 'OPTIONS':{'isolation_level':None}
5.运行错误TypeError: context must be a dict rather than set.
