Question

我正在按照教程添加Django中的朋友：Building Friend Networks

我得到一个404页面，因为如果在request.GET中找不到用户名，我已经在我的代码中设置了它来引发Http404：

views.py：

def friend_add(request):
    if 'username' in request.GET:
        friend = get_object_or_404(User, username=request.GET['username'])
        friendship = Friendship(from_friend=request.user, to_friend=friend)
        friendship.save()
        return HttpResponseRedirect('/friends/%s' % request.user.username)
    else:
        raise Http404

urls.py：

url(r'^friend/add/(?P<username>\w+)$', photo.views.friends_request),
url(r'^friends/(?P<username>\w+)$', photo.views.friends),
url(r'^request_sent/$', photo.views.friend_add),

我正在使用这样的模板标签，如教程所示：

{% ifequal user.username abuild.user %}
    <a href="/builds/friends/{{ user.username }}">view your friends</a>
{% else %}
    {% if is_friend %}
        <a href="/builds/friends/{{ abuild.user }}">
        {{ abuild.user }} is a friend of yours</a> 
    {% else %}
        <a href="/builds/request_sent/">
        add {{ abuild.user}} to your friends</a> 
    {% endif %}
    - <a href="/builds/friends/{{ abuild.user }}">
    view {{abuild.user}}'s friends</a>
{% endifequal %}

当我点击/request_sent/的链接时，如何确保获取用户名？

abuild.user是我要添加的用户，而user.username是登录的用户。

您应该像在其他情况下那样在网址中传递用户名。

因此，您的模板将更改为

<a href="/builds/request_sent/{{abuild.user.username}}">

urls.py将更改为

 url(r'^request_sent/(?P<username>\w+)$', photo.views.friend_add),

然后视图将变为

def friend_add(request, username):
    if 'username' in request.GET:
    ....

如何在request.GET Django中获取用户名
