Question

我想知道如果使用多个嵌套模式组重构我的应用程序的urlconf，将为Django寻找请求匹配模式提供性能提升。我不确定如何测试性能，但我已经尝试过，新版本起作用了。

我知道如果性能提升，它可能会微不足道。我只是开始这样做，看看模式是否更容易看作树;我更担心搞砸事情而不是提高速度。

以下是主用urlconf在/appname/包含的app的urlconf。

旧urlconf：

from django.contrib.auth.decorators import login_required
from django.conf.urls.defaults import patterns, include, url
from django.views.generic.simple import redirect_to

from appname import views

urlpatterns = patterns('',
    # Actions on sets of reports
    url(r'^reports/page(?P<page>[0-9]+)/$', login_required(views.appnameListView.as_view())),
    url(r'^reports/bill/', views.bill),

    # Actions on individual reports
    url(r'^report/new/', views.new),
    url(r'^report/(?P<reportNumber>[^/]+)/$', views.detail),
    url(r'^report/(?P<reportNumber>[^/]+)/delete/$', views.delete),
    url(r'^report/(?P<reportNumber>[^/]+)/edit/$', views.edit),
    url(r'^report/(?P<reportNumber>[^/]+)/print/$', views.detail_print),
    # url(r'^report/(?P<reportNumber>[^/]+)/pdf/$', views.detail_pdf),

    # Configure app settings
    url(r'^config/$', views.configure),
    url(r'^config/reporttype/(?P<id>[^/]+)/$', views.configure_ReportType),
    url(r'^config/reporttype/(?P<id>[^/]+)/delete/$', views.configure_ReportType_delete),
    url(r'^config/avgmethod/(?P<name>[^/]+)/$', views.configure_AvgMethod),
    url(r'^config/avgmethod/(?P<name>[^/]+)/delete/$', views.configure_AvgMethod_delete),
    url(r'^config/datatransformer/(?P<name>[^/]+)/$', views.configure_DataTransformer),
    url(r'^config/datatransformer/(?P<name>[^/]+)/delete/$', views.configure_DataTransformer_delete),

    # Catch all; #TODO: 404
    url(r'^', redirect_to, {'url': '/appname/reports/page1/'}),
)

新的urlconf：

from django.contrib.auth.decorators import login_required
from django.conf.urls.defaults import patterns, include, url
from django.views.generic.simple import redirect_to

from appname import views

urlpatterns = patterns('',
    # Actions on sets of reports
    url(r'^reports/', include(patterns('',
        url(r'^page(?P<page>[0-9]+)/$', login_required(views.appnameListView.as_view())),
        url(r'^bill/', views.bill),
    ))),

    # Actions on individual reports
    url(r'^report/', include(patterns('',
        url(r'^new/', views.new),
        url(r'^(?P<reportNumber>[^/]+)/$', views.detail),
        url(r'^(?P<reportNumber>[^/]+)/delete/$', views.delete),
        url(r'^(?P<reportNumber>[^/]+)/edit/$', views.edit),
        url(r'^(?P<reportNumber>[^/]+)/print/$', views.detail_print),
        # url(r'^(?P<reportNumber>[^/]+)/pdf/$', views.detail_pdf),
    ))),

    # Configure app settings
    url(r'^config/', include(patterns('',
        url(r'^$', views.configure),
        url(r'^reporttype/(?P<id>[^/]+)/$', views.configure_ReportType),
        url(r'^reporttype/(?P<id>[^/]+)/delete/$', views.configure_ReportType_delete),
        url(r'^avgmethod/(?P<name>[^/]+)/$', views.configure_AvgMethod),
        url(r'^avgmethod/(?P<name>[^/]+)/delete/$', views.configure_AvgMethod_delete),
        url(r'^datatransformer/(?P<name>[^/]+)/$', views.configure_DataTransformer),
        url(r'^datatransformer/(?P<name>[^/]+)/delete/$', views.configure_DataTransformer_delete),
    ))),

    # Catch all; #TODO: 404
    url(r'^', redirect_to, {'url': '/appname/reports/page1/'}),
)

我可以更进一步（使用正则表达式检查的5个变量中的4个被定义至少两次），但我担心失去可读性的原始好处。

如果您不想重新考虑并遵循DRY原则（在开发django代码时有时会合并很多），您应该对您的网址进行分组。因此，您将减少重复代码的数量并生成更易于维护的代码。举例来说，事实上，您可能希望将报告/网址更改为其他内容，然后您必须为每个网址执行此操作！
