Django 类型的重载视图

发布于 2024-11-16 15:20:05 字数 727 浏览 0 评论 0原文

如何在 Django 中创建重载视图？问题是我的观点可能只接受一个论点，也可能不接受。如果有参数，它会将其传递给视图。

让我们展示一下我正在尝试执行的操作

views.py

def member_list(request,message):
    memberList = Member.objects.all()
    return render_response(request, 'user/member_list.html', {'memberList': memberList,    'message':message })

def member_list(request,message):
    memberList = Member.objects.all()
    return render_response(request, 'user/member_list.html', {'memberList': memberList,    'message':message })

urls.py

(r'^member/list/$', 'views.member_list'),
(r'^member/list/(?P<message>[-\w]+)/$', 'views.member_list'),

执行此操作的正确方法是什么？

谢谢

How is this possible to make overloaded views in Django ?
The problem is I have a view which may accept exactly one argument or none.
If there is a argument, it will pass it to view.

Let show what I am tryin' to do

views.py

def member_list(request,message):
    memberList = Member.objects.all()
    return render_response(request, 'user/member_list.html', {'memberList': memberList,    'message':message })

def member_list(request,message):
    memberList = Member.objects.all()
    return render_response(request, 'user/member_list.html', {'memberList': memberList,    'message':message })

urls.py

(r'^member/list/
What is the right way to do this ?

, 'views.member_list'),
(r'^member/list/(?P<message>[-\w]+)/
What is the right way to do this ?
Thanks
, 'views.member_list'),

What is the right way to do this ?

Thanks

def member_list(request,message=None):
    if message:
        pass
    else:
        pass

def member_list(request,message=None):
    if message:
        pass
    else:
        pass

您可以在视图签名中使用可选参数，以发挥您的优势。

只需像这样定义您的视图：

def member_list(request, message=None):

然后，如果 URL 中存在匹配项，它将被填充。如果没有，它仍然是 None。

if message is None:
    # I got here via the '^member/list/
 （改编自这篇博文）
 URL regex
else:
    # I got here via the '^member/list/(?P<message>[-\w]+)/
 （改编自这篇博文）
 URL regex

You can use optional arguments in your view signature to your advantage here.

Simply define your view like this:

def member_list(request, message=None):

And then if there's a match in the URL, it'll get filled in. If not, it will still be None.

if message is None:
    # I got here via the '^member/list/

 URL regex
else:
    # I got here via the '^member/list/(?P<message>[-\w]+)/
