django - 如何到達用戶名在url

Question

我有博客系統，這是每個用戶都有自己的主頁像;

127.0.0.1/username

，每個用戶的登錄屏幕位於：127.0.0.1/username/panel

，並再次這裏是他們的管理面板：127.0.0.1/username/admin

登錄頁面;當我提交時;它必須將用戶重定向到管理面板。

但我需要到達目前在URL中的用戶名。我想我應該使用正則表達式。但是如何？我對regexp不好。

這裏是我的urls.py：

urlpatterns = patterns('blog.views', 
    url(r'^blog/(?P<username>[-\w]+)/$',view='index', name='index'), 
    url(r'^blog/(?P<username>[-\w]+)/post/(?P<postslug>[-\w]+)',view='singlePost', name='view_blog_post'), 
    url(r'^blog/(?P<username>[-\w]+)/panel/$', view='loguserin'), 
    url(r'^blog/(?P<username>[-\w]+)/admin/$', view='adminView', name='admin'), 
    url(r'^blog/(?P<username>[-\w]+)/admin/loggedout/$', view='logout', name='logout'), 
    url(r'^blog/(?P<username>[-\w]+)/admin/addpost/$', view='addpost',name='addpost'), 
    url(r'^blog/(?P<username>[-\w]+)/admin/editpost/(?P<post_id>\d+)', view='editPost', name='editpost'), 
    url(r'^blog/(?P<username>[-\w]+)/admin/delete/(?P<post_id>\d+)', view='delete_post', name='deletePost'), 

) 

，這裏是我的views.py [登錄部分]：

def loguserin(request,username): 
    if request.method=='POST': 
     uname = request.POST['username'] 
     password = request.POST['password'] 
     user = authenticate(username=uname, password=password) 
     form = LoginForm(request.POST) 
     if form.is_valid(): 
      if user is not None: 
       request.session['loggedin']="djangoo" 
       login(request, user) 
       return HttpResponseRedirect('/admin/') #--> ???? 
    else: 
     form = LoginForm() 

    return render_to_response('login.html',{'form':form,},context_instance=RequestContext(request)) 

Answer 1

其實，你已經擁有了用戶名：

from django.core.urlresolvers import reverse 
return HttpResponseRedirect(reverse('admin', args=[uname])) 

Answer 2

您需要的是帶參數的reverse：

from django.core.urlresolvers import reverse 

def loguserin(request,username): 
    if request.method=='POST': 
     uname = request.POST['username'] 
     password = request.POST['password'] 
     user = authenticate(username=uname, password=password) 
     form = LoginForm(request.POST) 
     if form.is_valid(): 
      if user is not None: 
       request.session['loggedin']="djangoo" 
       login(request, user) 
       return HttpResponseRedirect(reverse('admin', args=[uname])) #--> ???? 
    else: 
     form = LoginForm() 

    return render_to_response('login.html',{'form':form,},context_instance=RequestContext(request))
