带参数的django.shortcuts.redirect

Question

我试图用一个参数重定向到一个URL。部分views.py

def membership(request):
    errors = []
    members = Member.objects.all()
    ...
        if request.POST.get('subject', '') == "member_details":
            member = members.filter(id = request.POST.get('member', ''))
            return redirect("/membership/details/", m = member)
    ...

    return render(request, "membership.html", {"errors": errors, 'members': members})

我需要重定向到“成员/详细信息/”，但以“成员”作为参数或至少成员ID。

下面是我的url.py的一部分：

url(r'^admin/', include(admin.site.urls)),
url(r'^input/book/', 'library_app.views.input_book'),
url(r'^membership/$', 'library_app.views.membership'),
url(r'^membership/details/', 'library_app.views.member_details'),
url(r'^$', 'library_app.views.main'),

而"member_details“是我views.py的一部分：

def member_details(request, m="doesn't work"):
    error = []

    if request.method == "POST":
        pass

    return render(request, "member_details.html", {'m': m})

谢谢你的帮助！

如果要将成员包括在url中，则向url模式中添加一个命名群。例如，您可以将成员id包含在如下内容中：

url(r'^membership/details/(?P<member_id>\d+)/', 'library_app.views.member_details', name='member_details'),

然后，您的视图将member_id作为关键字参数。

from django.shortcuts import get_object_or_404

def member_details(request, member_id):
    member = get_object_or_404(id=member_id)
    # you might want to add checks to make sure 
    # that the logged in user is allowed to see this members details!
    ...

然后，您可以在硬编码的url中使用redirect：

return redirect("/membership/details/%s/ % member.pk")

或者，最好将视图名和member_id作为参数。

return redirect("member_details", member_id=member.id)
