如何Django的request.GET中獲取的用戶名

Question

我下面的教程可在Django添加好友：Building Friend Networks

我得到一個404頁面，因爲我已經在我的代碼設置它提出一個HTTP404如果用戶名是在不request.GET中發現：

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), 

我使用的模板標籤像這樣從教程中所示：

{% 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 %} 

如何確保我得到的用戶名，當我點擊進入/request_sent/一個鏈接？

abuild.user是誰我想添加的用戶，而user.username是登錄的人。

Answer 1

你應該通過用戶名的網址，你在其他情況下做的。

所以，你的模板將變爲

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

urls.py將變爲

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

然後查看將變爲

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