如何破译 Django 中的动态 URL 魔法
url(r'^([a-zA-Z0-9/_-]+):p:(?P<sku>[a-zA-Z0-9_-]+)/$', 'product_display', name='product_display'),
url(r'^(?P<path>[a-zA-Z0-9/_-]+)$', 'collection_display', name='collection_display'),
这是我当前的正则表达式：
我的问题是这样的：我希望能够匹配 Product_display 的正则表达式，而无需在正则表达式中使用 :p: 。我可以通过将 .html 放在末尾以将其与 collection_display 的正则表达式分开来做到这一点，但这并不能解决问题；如果正则表达式中没有“:p:”（如上面所示），URI“some-collection/other/other/sku.html”将匹配正则表达式一直到“.html”，而不管 sku。如何在不使用“:p:”结束集合正则表达式的情况下执行此操作。任何事情都会有所帮助。
谢谢
url(r'^([a-zA-Z0-9/_-]+):p:(?P<sku>[a-zA-Z0-9_-]+)/
That's my current regex:
My problem is this: I want to be able to match the product_display's regex without using :p: in the regex. I can do this by putting .html at the end to set it apart from the collection_display's regex, but that doesn't fix the problem that is; without the ":p:" in the regex as is above the URI "some-collection/other/other/sku.html" would match the regex all the way up to the ".html" disregarding the sku. How can I do this without using the ":p:" to end the collection regex. Anything will help.
Thanks

您的 sku 似乎不能包含斜杠，因此我建议使用“/”作为分隔符。然后就可以使用“.html”技巧了；事实证明，您的
collection_display正则表达式与点不匹配，但为了绝对确定，您可以使用负向后查找：或者，始终结束您的
collection_display网址带有斜杠，product_display带有“.html”（反之亦然）。It looks like your sku can't contain slashes, so I would recommend using "/" as your delimiter. Then the ".html" trick can be used; it turns out that your
collection_displayregex doesn't match the dot, but to make absolutely sure, you can use a negative look-behind:Alternatively, always end your
collection_displayurls with a slash andproduct_displaywith ".html" (or vice versa).
