1. 新建一个app01
python manage.py startapp app01
1 # 在 project 在外层 urls 的配置：
from django.contrib import admin
from django.urls import path
from django.conf.urls import url,include
#from . import views
from app01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
# 访问 cmdb 时候匹配到 app01 的url
url(r'^cmdb/', include("app01.urls")),
url(r'^monitor/', include("app02.urls")),
]
2 # 配置settings.py 文件
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
#'django.middleware.csrf.CsrfViewMiddleware', #注释这样，用来解决跨域问题
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
# 配置数据库连接
DATABASES = {
'default': {
#'ENGINE': 'django.db.backends.sqlite3',
#'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
'ENGINE': 'django.db.backends.mysql', # 数据库引擎
'NAME': 'project2', # 数据库名称
'HOST': '192.168.0.90', # 数据库地址，本机 ip 地址 127.0.0.1
'PORT': 3306, # 端口
'USER': 'cs', # 数据库用户名
'PASSWORD': 'cs123',
'OPTIONS': {
'isolation_level': "repeatable read",
},
}
}
# 配置静态文件位置
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
3 # project 的 __init__.py 修改mysql 信息
import pymysql
pymysql.install_as_MySQLdb()
2. 编写app01 的models 文件
from django.db import models
# Create your models here.
class UserGroup (models.Model):
uid = models.AutoField(primary_key=True)
caption = models.CharField(max_length=32,unique=True)
ctime = models.DateTimeField(auto_now_add=True, null=True)
uptime = models.DateTimeField(auto_now=True, null=True)
class UserInfo (models.Model):
username = models.CharField(max_length=32)
password = models.CharField(max_length=32)
# 会在 mysql 里面生成这两张表
3 . 编写app01 的 views.py 文件
实现通过页面查询查询、删除、修改功能
from django.shortcuts import render,HttpResponse,redirect
from django.views import View
from app01 import models
#class Home(View):
def detail(request, nid):
detail_info = USER_DICT[nid]
#obj = models.UserInfo.objects.filter(id=nid).first()
return render(request, 'detail.html', {'obj': detail_info})
def index(request):
return render(request, 'index.html')
def user_info(request):
if request.method == "GET":
user_list = models.UserInfo.objects.all()
#group_list = models.UserGroup.objects.all()
return render(request, 'user_info.html', {'user_list': user_list})
elif request.method == 'POST':
u = request.POST.get('user')
p = request.POST.get('pwd')
models.UserInfo.objects.create(username=u, password=p)
return redirect('/cmdb/user_info/')
def user_detail(request, nid):
obj = models.UserInfo.objects.filter(id=nid).first()
return render(request, 'user_detail.html', {'obj': obj})
def user_del(request, nid):
models.UserInfo.objects.filter(id=nid).delete()
return redirect('/cmdb/user_info/')
def user_edit(request, nid):
if request.method == "GET":
obj = models.UserInfo.objects.filter(id=nid).first()
return render(request, 'user_edit.html',{'obj': obj})
elif request.method == "POST":
nid = request.POST.get('id')
u = request.POST.get('username')
p = request.POST.get('password')
models.UserInfo.objects.filter(id=nid).update(username=u,password=p)
return redirect('/cmdb/user_info/')
4. 编写html 页面
4.1 user_info.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
body{
margin: 0;
}
.menu{
display: block;
padding: 5px;
">darkgreen;
}
</style>
</head>
<body>
<div style="height: 48px;">black;color: white">
userinfo
</div>
<div>
<div style="position: absolute;top:48px;bottom: 0;left: 0; 200px;">lightblue;">
<a class="menu" href="/cmdb/user_info/">用户管理</a>
<a class="menu" href="/cmdb/user_group/">用户组管理</a>
</div>
<div style="position:absolute;top:48px;left: 210px;bottom: 0;right: 0;overflow: auto">
<h3>添加用户</h3>
<form method="POST" action="/cmdb/user_info/">
<input type="text" name="user" />
<input type="text" name="pwd" />
<select name="group_id">
{% for item in group_list %}
<option value="{{ item.uid }}">{{ item.caption }}</option>
{% endfor %}
</select>
<input type="submit" value="添加"/>
</form>
<h3>用户列表</h3>
<ul>
{% for row in user_list %}
<li>
<a href="/cmdb/userdetail-{{ row.id }}/">{{ row.username }}</a> |
<span> {{ row.user_group.caption }} </span>
<a href="/cmdb/userdel-{{ row.id }}/">删除</a> |
<a href="/cmdb/useredit-{{ row.id }}/">编辑</a>
</li>
{% endfor %}
</ul>
</div>
</div>
</body>
</html>
4.2 用户编辑 user_edit.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
body{
margin: 0;
}
.menu{
display: block;
padding: 5px;
}
</style>
</head>
<body>
<div style="height: 48px;background-color: black;color: white">
用户编辑
</div>
<div>
<div style="position: absolute;top:48px;bottom: 0;left: 0; 200px;background-color: brown;">
<a class="menu" href="/cmdb/user_info/">用户管理</a>
<a class="menu" href="/cmdb/user_group/">用户组管理</a>
</div>
<div style="position:absolute;top:48px;left: 210px;bottom: 0;right: 0;overflow: auto">
<h1>编辑用户</h1>
<form method="post" action="/cmdb/useredit-{{ obj.id }}/">
<input style="display: none" type="text" name="id" value="{{ obj.id }}" />
<input type="text" name="username" value="{{ obj.username }}" />
<input type="text" name="password" value="{{ obj.password }}"/>
<input type="submit" value="提交" />
</form>
</div>
</div>
</body>
</html>
4.3 用户详细信息 user_detail.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
body{
margin: 0;
}
.menu{
display: block;
padding: 5px;
}
</style>

<h5>{{ obj.id }}</h5>
<h5>{{ obj.name }}</h5>
<h5>{{ obj.password }}</h5>
</div>
</div>
5. 效果验证
点击删除 会把用户删除 ，点击用户名字 显示 用户的id 和密码信息
编辑
