python - Django 的模式方法的第一个参数有什么用？

Question

patterns 的第一个参数(在下面的示例中包含 '')有什么意义？ ？

urlpatterns = patterns('',
    (r'^articles/2003/$', 'news.views.special_case_2003'),
    (r'^articles/(\d{4})/$', 'news.views.year_archive'),
)

有时我看到它被填满了，像这样:

urlpatterns = patterns(
    'zinnia.views.entries',
    url(r'^$',
        'entry_index', entry_conf_index,
        name='zinnia_entry_archive_index'),
    )

Answer 1

它是 View 路径的前缀。查看documentation for patterns .

使用此参数的第一个示例的等价物是:

urlpatterns = patterns('news.views',
    (r'^articles/2003/$', 'special_case_2003'),
    (r'^articles/(\d{4})/$', 'year_archive'),
)

第一个参数设置为 '' 的第二个示例的等价物是:

urlpatterns = patterns('',
    url(r'^$',
        'zinnia.views.entries.entry_index', entry_conf_index,
        name='zinnia_entry_archive_index'),
    )
