使 Regex Django URL 令牌成为可选

发布于 2024-08-23 11:39:12 字数 624 浏览 5 评论 0原文

您有一个在 Django 中接受 first_name 和 last_name 的 URL：

('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)/$','some_method'),

如何在不创建任何新行的情况下包含 title 的可选 URL 标记。我的意思是，在理想的情况下：

#A regex constant
OP_REGEX = r'THIS IS OPTIONAL<title>[a-z]'
#Ideal URL
('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)/OP_REGEX/$','some_method'),

这是否可以在不创建新行的情况下实现，即

('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)/(?P<title>[a-zA-Z]+)/$','some_method'),

You have a URL which accepts a first_name and last_name in Django:

('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)/
How would you include the OPTIONAL URL token of title, without creating any new lines. What I mean by this is, in an ideal scenario:
#A regex constant
OP_REGEX = r'THIS IS OPTIONAL<title>[a-z]'
#Ideal URL
('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)/OP_REGEX/
Is this possible without creating a new line i.e.
('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)/(?P<title>[a-zA-Z]+)/
,'some_method'),

Is this possible without creating a new line i.e.

,'some_method'),

('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)(?:/(?P<title>[a-zA-Z]+))?/
不要忘记在视图中为 title 指定默认值。
,'some_method'),

('^(?P<first_name>[a-zA-Z]+)/(?P<last_name>[a-zA-Z]+)(?:/(?P<title>[a-zA-Z]+))?/
Don't forget to give title a default value in the view.

如果您正在寻找多个可选参数，而没有任何必需的参数，只需在开头省略“/”，例如：

re_path(r'^view(?:/(?P<dummy1>[a-zA-Z]+))?(?:/(?P<dummy2>[a-zA-Z]+))?(?:/(?P<dummy3>[a-zA-Z]+))?/
您可以浏览：
http://localhost:8000/view/?dummy1=value1&dummy2=value2&dummy3=value3

, views.MyView.as_view(), name='myname'),

您可以浏览：

In case your are looking for multiple optional arguments, without any required ones, just omit "/" at the beginning, such as:

re_path(r'^view(?:/(?P<dummy1>[a-zA-Z]+))?(?:/(?P<dummy2>[a-zA-Z]+))?(?:/(?P<dummy3>[a-zA-Z]+))?/
which you can browse at:
http://localhost:8000/view/?dummy1=value1&dummy2=value2&dummy3=value3

, views.MyView.as_view(), name='myname'),

which you can browse at:
