django实现简单的资产管理平台

标签：python

自学python有一段时间了，难得有时间自己写了一个简单的资产管理平台.用AdminLTE做为前端页面django做为后台采用paramkio模块连接服务器并从服务器中提取数据。
开发环境
centos 7
python 2.7
django 1.11.8

def login(request):
     if request.session.get('is_login',None):
        return redirect('/index/')
     if request.method == "POST":
        username = request.POST.get('username')
        password = request.POST.get('password')
        if username and password:
            try:
#                 p = user.objects.get(name = u).password
                user = models.user.objects.get(name = username)
            except:
                return render(request,'login.html')
            if password == user.password:
                request.session['is_login'] = True
                request.session['user_id'] = user.id
                request.session['user_name'] = user.name
                return redirect('/index/')
     return render(request, 'login.html')

对登陆做出限制写一个限制登陆访问的装饰器

def my_login(func):

       if request.session.has_key('user_id'):
          return func(request)
       else:
          return redirect('/login/')
    return check_login

    on_dev = int(on)
    off_dev = int(off)
    return render(request, 'index.html',locals())

有基本的增删该查的功能，用了paramiko模块远程ssh提取数据速度不是很理想，后期可以用ajax做异步处理，或是考虑用salt或是agent。

用户管理

也是基本增删改功能，后期可以添加组实现资产权限管理
部分代码
与上面代码基本一致，在此不贴出。

服务器发布
建议采用django+uwsgi+nginx
uwsgi配置

pip install uwsgi #环境安装

        location / {
        include uwsgi_params;
        uwsgi_connect_timeout 30;
        uwsgi_pass unix:/root/main/uwsgi.sock;
        }


	location /static/ {
        alias /root/myapp/static/;
        index index.html index.htm;
