我正在使用本教程http://lightbird.net/dbe/forum2.html创建一个论坛,但遇到了一个错误。
当我单击编辑配置文件时,它假设指向此页面而不是我得到一个错误(下)
DoesNotExist at /forum/profile/1/
UserProfile matching query does not exist.
Request Method: GET
Request URL: http://127.0.0.1:8000/forum/profile/1/
Django Version: 1.4.3
Exception Type: DoesNotExist
Exception Value:
UserProfile matching query does not exist.
Traceback Switch to copy-and-paste view
C:\djcode\mysite\forum\views.py in profile
profile = UserProfile.objects.get(user=pk)
我认为这个错误意味着,django 无法接收我的管理员登录。
这是我的 fbase.html 的一部分
<a href="{% url ben:profile user.pk %}">Edit profile</a>
这指向我的 URLconf。
from django.conf.urls import patterns,include,url
from django.contrib import admin
from django.conf import settings
urlpatterns = patterns('forum.views',
url(r'^$','main',name='main'),
url(r"^forum/(\d+)/$", "forum",name ="forum"),
url(r"^thread/(\d+)/$","thread",name = "thread"),
url(r"^post/(new_thread|reply)/(\d+)/$", "post",name = "post"),
url(r"^reply/(\d+)/$", "reply" , name ="reply"),
url(r"^new_thread/(\d+)/$", "new_thread" , name ="new_thread"),
url(r"^profile/(\d+)/$", "profile",name= "profile"),
)
并进入我的视图功能
def profile(request, pk):
"""Edit user profile."""
profile = UserProfile.objects.get(user=pk)
img = None
if request.method == "POST":
pf = ProfileForm(request.POST, request.FILES, instance=profile)
if pf.is_valid():
pf.save()
# resize and save image under same filename
imfn = pjoin(MEDIA_ROOT, profile.avatar.name)
im = PImage.open(imfn)
im.thumbnail((160,160), PImage.ANTIALIAS)
im.save(imfn, "JPEG")
else:
pf = ProfileForm(instance=profile)
if profile.avatar:
img = "/media/" + profile.avatar.name
return render_to_response("forum/profile.html", add_csrf(request, pf=pf, img=img))
这是我的models.py
