使用Django1.11创建简单的资产管理平台

1：首先创建一个django项目

[root@localhost opt]# django-admin startproject ops
CommandError: '/opt/ops' already exists
[root@localhost opt]# cd ops
[root@localhost ops]# tree
.
├── manage.py
└── ops
    ├── __init__.py
    ├── settings.py
    ├── urls.py
    └── wsgi.py

1 directory, 5 files
[root@localhost ops]#

2：继续创建一个APP

[root@localhost ops]# django-admin startapp polls
[root@localhost ops]# tree
.
├── manage.py
├── ops
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── polls
    ├── admin.py
    ├── apps.py
    ├── __init__.py
    ├── migrations
    │   └── __init__.py
    ├── models.py
    ├── tests.py
    └── views.py

3 directories, 12 files
这里要注意下settings.py是全局的配置，即项目下的所有全局配置都在这里，下面要说的urls.py也类似

3：配置全局的setting文件

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
# 变量，路径是我们项目的初始路径/opt/ops

4: 启用urls.py

from django.conf.urls import url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
]

5: APP下的models

# -*- coding: utf-8 -*-

from __future__ import unicode_literals

from django.db import models

# Create your models here.
class ServerList(models.Model):
    hostname=models.CharField(max_length=50,verbose_name=u'主机名')
    user=models.CharField(max_length=50,verbose_name=u'使用人')
    brand=models.CharField(max_length=50,verbose_name=u'品牌')
    sn=models.CharField(max_length=50,verbose_name=u'SN')
    mac=models.CharField(max_length=50,blank=True,null=True,verbose_name=u'MAC地
址')
    os=models.CharField(max_length=50,verbose_name=u'系统版本')
    cpu=models.CharField(max_length=50,verbose_name=u'CPU')
    memory=models.CharField(max_length=50,verbose_name=u'内存')
    desk=models.CharField(max_length=50,verbose_name=u'硬盘')
    status=models.CharField(blank=True,null=True,verbose_name=u'状态')
    remark=models.CharField(blank=True,null=True,verbose_name=u'注释')
    dept=models.CharField(max_length=50,verbose_name=u'部门')

    def __unicode__(self):
        return u'%s %s %s %s %s %s %s %s %s %s %s %s' %(self.hostname,self.dept,self.user,self.brand,self.os,self.cpu,self.memory,self.desk,self.mac,self.sn,self.status,self.remark)

6: APP下的admin.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.contrib import admin
from polls.models import ServerList
class TitleList(admin.ModelAdmin):
    list_display = ('hostname','user','brand','sn','mac','os','cpu','memory','desk','status','remark','dept')
    search_fields = ('hostname','user','brand','sn','mac','os','cpu','memory','desk','status','remark','dept')
admin.site.register(ServerList,TitleList)

7：创建数据库并赋予权限（安装mysql的过程就不详细介绍）

mysql> CREATE DATABASE `ops` /*!40100 DEFAULT CHARACTER SET utf8 */;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON `ops`.* TO 'ops'@'localhost' identified by 'ops';
Query OK, 0 rows affected (0.06 sec)

mysql>

8：同步数据库

[root@localhost ops]# python manage.py makemigrations polls
Migrations for 'polls':
  polls/migrations/0001_initial.py
    - Create model ServerList
[root@localhost ops]# python manage.py migrate polls
Operations to perform:
  Apply all migrations: polls
Running migrations:
  Applying polls.0001_initial... OK

9:

[root@localhost ops]# python manage.py createsuperuser
Username (leave blank to use 'root'):
Email address: mail@mail.com
Password:
Password (again):

10：打开站点进入127.0.0.1/admin，使用刚才创建的用户登录
