python - Django中的空白网址格式

我继承了Django应用，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),
)

这是在做什么有什么事吗

最佳答案

patterns()函数中需要它，因为patterns（）的第一个参数用作URL的公共视图前缀。从文档：

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'),
)

可以更简单地写为：

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，urlpatterns中的urls.py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。
