我有下面的代碼,並有兩個問題。 1.我無法獲得加入的連接,也沒有顯示在頁面上。 2.管理界面未加載。由於以下錯誤導致無法加載管理界面

我重新創建了數據庫徹底檢查了代碼,真的需要幫助。

Views.py。

我註釋掉異常後得到
from django.conf import settings 
from django.shortcuts import render, HttpResponseRedirect, Http404 
from.models import Join 
from .forms import EmailForm, JoinForm 

def get_ip(request): 
    try: 
     x_forwarded = request.META.get("HTTP_X_FORWARDED_FOR") 
     if x_forwarded: 
      ip = x_forwarded.split(",")[0] 
     else: 
      ip = request.META.get("REMOTE_ADDR") 
    except: 
     ip = "" 
    return ip 

import uuid 
def get_ref_id(): 
    ref_id = str(uuid.uuid4())[:11].replace('-', '').lower() 

    try: 
     id_exists = Join.objects.get(ref_id=ref_id) 
     get_ref_id() 
    except: 
     return ref_id 
def home(request): 
    try: 
     join_id = request.session['join_id_ref'] 
     obj = Join.objects.get(id=join_id) 

    except: 
     obj = None 

    form = JoinForm(request.POST or None) 
    if form.is_valid(): 
     new_join = form.save(commit=False) 
     email = form.cleaned_data['email'] 
     new_join_old, created = Join.objects.get_or_create(email=email) 
     if created: 
      new_join_old.ref_id = get_ref_id() 
      if not obj == None: 
       new_join_old.friend = obj 
      new_join_old.ip_address = get_ip(request) 
      new_join_old.save() 
     return HttpResponseRedirect("/%s" %(new_join_old.ref_id)) 

    context = {"form": form} 
    template = 'home.html' 
    return render(request, template, context) 

def share(request, ref_id): 
    #try: 
     join_obj = Join.objects.get(ref_id=ref_id) 
     friends_referred = Join.objects.filter(friend=join_obj) 
     count = join_obj.referral.all().count() 
     ref_url = settings.SHARE_URL + str(join_obj.ref_id) 
     context = {"ref_id": join_obj.ref_id, "count": count, "ref_url": ref_url} 
     template = "share.html" 
     return render(request, template, context) 
    #except: 
     #raise Http404 

錯誤消息:

DoesNotExist at /admin 
Join matching query does not exist. Lookup parameters were {'ref_id': u'admin'} 

Urls.py包括以下內容。

from django.contrib import admin 
admin.autodiscover() 

urlpatterns = patterns('', 
    url(r'^admin/', include(admin.site.urls)), 
    url(r'^$', 'joins.views.home', name='home'), 
    url(r'^(?P<ref_id>.*)$', 'joins.views.share', name='share'), 
)

首先,您需要正確糾正「def share」的意圖。 – doniyor 2014-11-01 07:53:58

其次,''join_obj = Join.objects.get(ref_id = ref_id)''這不是錯誤信息 – doniyor 2014-11-01 07:55:07

請顯示urls.py.並確保該對象真的在db中,你正在請求。 – doniyor 2014-11-01 08:02:08

你符合

url(r'^(?P<ref_id>.*)$', 'joins.views.share', name='share'), 

比賽admin/正則表達式,以及你應該使用的東西少 「貪婪」。
