django--创建网站小样

安装Django

首先在cmd下输入pip install Django,然后开始安装，Django将要被安装到Python的Lib下site-packages。

然后是配置环境变量，将这几个目录添加到系统环境变量中：C:\ProgramData\Anaconda3\Lib\site-packages\django. (前提已经安装了Anaconda3，且它自动会添加路径)，添加完成后就可以使用Django的django-admin命令新建工程了。

检查是否安装成功

输入以下命令进行检查:

>>>import django

>>>print （django.get_version()）

新建项目和应用

• 放项目文件：这里是E盘
• 按住shift，再点击右键，打开CMD
• 输入：django-admin startproject demoproject
• 这样就新建了个名为demoproject的项目文件夹
• 输入：django-admin  startapp demo
• 这样就新建了一个名为search的应用文件夹
• 将demo文件夹移到demoproject文件夹里面，并删除migrations文件

修改demoproject和demo相关.py文件

• 打开settings.py，找到INSTALLED_APPS
  
• TEMPLATE_DIRS = (“E:/search_engine/search_engine/search/templates”,)#模板文件路径
  
• STATICFILES_DIRS = ( 
  os.path.join(BASE_DIR, “static”).replace(‘\’,’/’), 
  )#静态文件路径

settings.py

修改urls.py

from django.shortcuts import renderfrom django.http import HttpResponse# Create your views here.def search_form(request):    return render('search_form.html')

url(r'^admin/', admin.site.urls),]#设置静态文件路径urlpatterns += staticfiles_urlpatterns()

修改views.py

from django.shortcuts import renderfrom django.http import HttpResponse# Create your views here.def search_form(request):    return render('search_form.html')

定义html模板search_form.html

<!DOCTYPE HTML PUBLIC "‐//W3C//DTD HTML 4.01//EN"><html lang="en"><head>    <title>{% block title %}{% endblock %}</title></head><body>    {% block content %}    {% endblock %}    {% block footer %}    {% endblock %}</body></html>

• 先在templates文件夹中新建一个基类模板base.html
• 然后再新建一个search_form.html继承并扩展

{% extends "base.html" %}{% block title %}Search_form{% endblock %}<div id="logo" style="text-align: center; margin-top: 15%">    <img src="{% static "images/qi.png" %}" alt="qi image"/></div><form action="/search/" method="get">    <div  style="width: 100%; text-align: center;margin-top: 10">        <input type="text" name="q" maxlength="100" size="60">        <input type="submit" value="Search">    </div></form><div style="text-align: center; margin-top: 50">    <p>欢迎来到樱桃小丸子的世界！</p></div>{% endblock %}

放入静态资源（图片，js，css）

• 在static文件夹中新建一个images文件夹
• 里面放入qi.png图片文件

最后显示：

最后图片加载不出来，我需要在进行了解，我有按照一篇博客http://www.cnblogs.com/pyfreshman/p/5046887.html还是不能加载出来，看来对Django 仅仅还在入门阶段，需要花费
