Django工程的建立以及小网站的编写
这篇博文会详细的介绍如何创建django工程，介绍我如何做了第一个网站。本文基于windows7安装了python2.7.12，Django1.8.18(LTS)版。采用的IDE为pycharm。建议安装Django的时候采用pip安装，因为可能自己电脑环境缺少哪个包的话，pip能给你安装完全。命令是
1 pip install django==1.8.18
本文的目的是建立一个小网站，能够在测试过程中随时记录所出现的bug，网站命名为Buglist，根据描述，便知道主要的用途就是和数据库交互，并且是在Linux服务器上部署，所以采用mysql数据库，并且还要记录是谁进行登陆，记录这些bug,所以要用django的后台管理页面。so，创建一个buglist工程吧。
让我们看看Django项目的结构：
1 |- buglist/ 2 |- manage.py 3 |- templates/ 4 |- buglist/ 5 |- __init__.py 6 |- settings.py 7 |- urls.py 8 |- wsgi.py
-
manage.py: 一个命令行交互文件，用于显示项目的运行情况，不用对这个文件做任何修改。
- templates/:用来存放静态文件，css,js,ico文件等等
- buglist/: 你项目的目录下包含着以下文件：
- __init__.py ： 空的Python文件，用来告诉Python将这个项目目录视为一个Python模块。
- settings.py ： 项目的配置和设置文件，用命令行生成的Django项目会自动生成默认配置。
- urls.py ： URL配置文件，每一行URL都对应一个相应的视图（view）
- uwsgi.py ： 配置您的项目，让它作为一个WSGI程序运行。
在工程中新建文件夹
此时需要在settings.py文件中修改几个地方，数据库
1 DATABASES = { 2 ‘default‘: { 3 ‘ENGINE‘: ‘django.db.backends.mysql‘, 4 ‘NAME‘: ‘buglist‘, 5 ‘USER‘:‘buglist‘, 6 ‘PASSWORD‘:‘buglist‘, 7 ‘HOST‘:‘‘, ----此处默认即为本地数据库 8 ‘PORT‘:‘‘, -----此处默认即为mysql默认端口 9 } 10 }
时区及静态文件夹的设置
1 TIME_ZONE = ‘Asia/Shanghai‘ 2 3 4 STATIC_URL = ‘/static/‘ 5 STATIC_ROOT = os.path.join(BASE_DIR,‘static‘) 6 STATICFILES_DIRS = (‘static/css‘, 7 ‘static/bootstrap‘, 8 ‘static/images‘, 9 ‘static/js‘, 10 )
创建一个app handle 可以采用tool --> Run manage.py Task 来创建或者采用python manage.py startapp handle来创建，不要忘记在settings.py中添加
1 INSTALLED_APPS = ( 2 ‘django.contrib.auth‘, 3 ‘django.contrib.contenttypes‘, 4 ‘django.contrib.sessions‘, 5 ‘django.contrib.messages‘, 6 ‘django.contrib.staticfiles‘, 7 ‘handle‘, 8 )
首先完成前段部分，login.html，采用POST的方式往后台传输数据，采用了boostrap，简单易用，并且采用了模板语言
1 <!Doctype html> 2 {% load staticfiles %} 3 <html> 4 <head> 5 <meta http-equiv=Content-Type content="text/html;charset=utf-8"> 6 <meta name="description" content="BugList"> 7 <link rel="icon" href="{% static "images/favicon.ico" %}" type="image/x-icon"/> 8 <link rel="stylesheet" href="{% static "login.css" %}" type="text/css"/> 9 <link rel="stylesheet" href="{% static "css/bootstrap.min.css"%}" type="text/css"/> 10 <title>BugList</title> 11 </head> 12 <body> 13 <div class="container"> 14 <div class="row"> 15 <div class="col-sm-6 col-md-4 col-md-offset-4"> 16 <div class="account-wall"> 17 <h1 class="text-center login-title">Sign in to continue</h1> 18 <form class="form-signin" method="POST" action="/login/"> 19 {% csrf_token %} 20 <input name="user" type="user" class="form-control" id="user" placeholder="Username" required autofocus> 21 <input name="password" type="password" class="form-control" id= ‘password‘ placeholder="Password" required> 22 <button class="btn btn-lg btn-primary btn-block" type="submit" id="">Sign in</button> 23 <p style="color: red;text-align: center;"> {{ loginstatus }} </p> 24 </form> 25 26 </div> 27 </div> 28 </div> 29 </div> 30 31 <script type="text/javascript" src="{% static "jquery-3.2.0.min.js" %}" ></script> 32 <script type="text/javascript" src="{% static "js/bootstrap.min.js" %}"></script> 33 </body> 34 </html>
web模板，采用模板语言的话就是扩展性比较好,layout.html
1 <!DOCTYPE html> 2 {% load staticfiles %} 3 <html lang="en"> 4 <head> 5 <meta charset="utf-8"> 6 <meta http-equiv="X-UA-Compatible" content="IE=edge"> 7 <meta name="viewport" content="width=device-width, initial-scale=1"> 8 <meta name="description" content=""> 9 <meta name="author" content=""> 10 <link rel="icon" href="{% static "favicon.ico" %} " type="image/x-icon" /> 11 12 <title>BugList</title> 13 14 <!-- Bootstrap core CSS --> 15 <link href="{% static "css/bootstrap.min.css" %}" rel="stylesheet" type="text/css"/> 16 <!-- Custom styles for this template --> 17 <link href="{% static "dashboard.css" %}" rel="stylesheet" type="text/css"/> 18 <link href="{% static "custom.css" %}" rel="stylesheet" type="text/css"/> 19 {% block css %} 20 {% endblock %} 21 </head> 22 23 <body> 24 25 <nav class="navbar navbar-inverse navbar-fixed-top"> 26 <div class="container-fluid"> 27 <div class="navbar-header"> 28 <div class="navbar-brand"><a style=‘text-decoration:none;‘ href="/">BugList</a></div> 29 </div> 30 <div id="navbar" class="navbar-collapse collapse"> 31 <ul class="nav navbar-nav navbar-right"> 32 <li class="dropdown"> 33 {% if user.is_active %} 34 <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false" id="login_user">{{ user.username }}<span class="caret"></span></a> 35 <ul class="dropdown-menu"> 36 <li><a href="/logout/">logout</a></li> 37 </ul> 38 {% endif %} 39 </li> 40 </ul> 41 </div> 42 </div> 43 </nav> 44 45 <div class="container-fluid"> 46 <div class="row"> 47 <div class="col-sm-2 col-md-2 sidebar"> 48 <ul class="nav nav-sidebar" id="bar"> 49 <li ><a href="/overview/">Overview</a></li> 50 <li ><a href="/search/" >Search Errors</a></li> 51 <li ><a href="/record/" >Record Errors</a></li> 52 </ul> 53 </div> 54 <div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"> 55 {% block con %} 56 {% endblock %} 57 </div> 58 </div> 59 </div> 60 <script src="{% static "jquery-3.2.0.min.js" %}"></script> 61 <script src="{% static "js/bootstrap.min.js"%}"></script> 62 <script src="{% static "custom.js" %}"></script> 63 {% block js %} 64 {% endblock %} 65 </body> 66 </html>
