Django 中的空白 URL 模式

Question

我继承了一个 Django 应用程序并注意到 urlpatterns += patterns('') 和整个 urls.py 中的等效项。

例如

urlpatterns = patterns(
    '', 
    url(r'^index.html', render_index),
)

#... 

urlpatterns += patterns(
    '', 
    url(r'^page.html', another_controller),
)

这是在做什么？任何事物？

Answer 1

patterns() 函数中需要它，因为 patterns() 的第一个参数用作您的网址的通用视图前缀。来自文档：

urlpatterns = patterns('',
    (r'^articles/(\d{4})/$', 'news.views.year_archive'),
    (r'^articles/(\d{4})/(\d{2})/$', 'news.views.month_archive'),
    (r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'news.views.article_detail'),
)

更简单地写为：

urlpatterns = patterns('news.views',
    (r'^articles/(\d{4})/$', 'year_archive'),
    (r'^articles/(\d{4})/(\d{2})/$', 'month_archive'),
    (r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'article_detail'),
)

但是，从 Django 1.8 开始，urls.py 中的 urlpatterns 变量是用一个简单的列表创建的：

urlpatterns = [ 
    url(r'^index.html', render_index),
    url(r'^page.html', another_controller),
]

并且不需要此视图前缀参数。
