Question

我在主urlconf中有这个URL：

url(r'^confirm-invite/(?P<token>[\w-]+)/$', confirm_invite, name="confirm_invite_page"),

这是它连接的（WIP版本）视图：

def confirm_invite(req, token):
    template_name = 'invites/confirm_invite.html'

    if req.method == 'POST':
        form = ActivationForm(req.POST)
        if form.is_valid():

            try:
                auth_user = authenticate(username=user.username, password=form.cleaned_data['activation_code'])
            except:
                return HttpResponse('didnt authenticate')
            if auth_user is None:
                return HttpResponse('auth_user is none')
            login(req, auth_user)
            return HttpResponse('you activated your account')
        else:
            return HttpResponse('form error foo')
    else:
        invite = get_object_or_404(Invite, token=token)
        user = invite.user
        if user.is_active == True:
            return HttpResponse('user is already active')
        else:
            form = ActivationForm()
            return render(req, template_name, {'form': form})

这是HTML的片段：

<form action="{% url 'confirm_invite_page' token %}" method="post">{% csrf_token %}
        {{form.as_p}}
        <input type="submit" value="Activate">
</form>

由于某些原因，HTML中的反向网址{% url 'confirm_invite_page' token %}会抛出匹配问题

以下是完整的追溯：

我认为这是正确设置的，考虑到文档，匹配的问题是什么？

Answer 1

您需要将最后一行更改为

return render(req, template_name, {'form': form, 'token': token})

因为否则，模板没有此变量。

Answer 2

“令牌”是否？它似乎基于堆栈跟踪。您需要确保将变量设置为某个值，否则url模板标记将失败，因为它将查找匹配，其中url中没有参数，即使您显然也是如此。

模板操作URL中的NoReverseMatch
