通用视图
有的时候, views.py 的处理只是简单的返回一个 html, 这种情况就可以通过 [通用视图] 简写在 urls.py 中.
<span style="color: #008000">#</span><span style="color: #008000">from django.views.generic.simlpe import direct_to_template 版本更新, 用下面这个代替</span>
<span style="color: #0000ff">from</span> django.views.generic.base <span style="color: #0000ff">import</span><span style="color: #000000"> TemplateView
urlpatterns </span>=<span style="color: #000000"> [
url(r</span><span style="color: #800000">'</span><span style="color: #800000">^about/$</span><span style="color: #800000">'</span>, TemplateView.as_view(template_name=<span style="color: #800000">'</span><span style="color: #800000">about.html</span><span style="color: #800000">'</span><span style="color: #000000">)),
]</span>
以上是通用视图的最基本应用, 通用视图还可以用来渲染模板. 它的优势常常体现在对数据库的访问上. 参考文章: http://www.pythontip.com/blog/post/12172/
有的时候, views.py 里的视图函数有部分相同的逻辑, 此时可以把这部分逻辑提取出来.
views.py
<span style="color: #0000ff">def</span><span style="color: #000000"> view1(request):
</span><span style="color: #0000ff">return</span> render_to_response(<span style="color: #800000">'</span><span style="color: #800000">1.html</span><span style="color: #800000">'</span><span style="color: #000000">)
</span><span style="color: #0000ff">def</span><span style="color: #000000"> view2(request):
</span><span style="color: #0000ff">return</span> render_to_response(<span style="color: #800000">'</span><span style="color: #800000">2.html</span><span style="color: #800000">'</span><span style="color: #000000">)
</span><span style="color: #0000ff">def</span><span style="color: #000000"> views(func):

</span><span style="color: #0000ff">return</span> view
urls.py
