Question

这可能是一个alreday问的错误，但在我的情况下错误是相同的但不同的问题，大家好我已经写了一个django apllication，其中我有一套模板

的login.html
Logout.html
dashboards.html

在登录表单中进行身份验证后，用户将转发到dashboards.html。我的问题是，如果用户直接尝试 dashboards.html 而不通过登录页面，那么我收到此错误。而不是这个我想显示用户login.html如果他试图直接访问dashboards.html。提前谢谢。

我的views.py看起来像

from django.shortcuts import render
from django.contrib.auth.models import User, Group
from django.contrib.auth import authenticate, login, logout
from ow_dashboard.models import Dashboard
from django.http import HttpResponse
from django.template import RequestContext, loader
from django.shortcuts import render
from django.shortcuts import render_to_response

def custom_login(request):
    if request.user.is_authenticated():
        return HttpResponseRedirect('dashboards')        
    return login(request, 'login.html', authentication_form=LoginForm)

def custom_logout(request):
    return logout(request, next_page='/')

def user(request):
    groups = request.user.groups.all()
    if request.user.is_anonymous():
        groups = []
    dashboards = Dashboard.objects.filter(owner=groups)

    context = {
        'user': request.user,
        'groups': groups,
        'dashboards': dashboards,
    }
    return render_to_response('registration/dashboards.html', context, context_instance=RequestContext(request))

# Create your views here.

和dashboards.html就像

{% load staticfiles %}

<div class="row" style="background-color: #eee; width:19%; height:968%; margin-top:10px;">
<div class="col-sm-2" style="background-color: #eee;">Dashboards
{% for Dashboard in dashboards %}
<strong><a href="#">{{ Dashboard.d_name }}</a><strong>
{% endfor %}
</div>  
</div>



<div class="right-contain" style="background-color: #eee; margin-top:-581px; margin-left:18%; width:83%; height:968%;">

<div class="row" style="background-color: #eee;  margin-top:3px;"><marquee>Footer</marquee>

{% endblock %}
</body>
</html>

和urls.py是

from django.conf.urls import patterns, include, url
from django.contrib import admin
from django.contrib.auth.models import User

urlpatterns = patterns('',

    url(r'^admin/', include(admin.site.urls)),
    url(r'^login/$', 'django.contrib.auth.views.login',),
    url(r'^logout/$', 'django.contrib.auth.views.logout'),
    url(r'^dashboards/$', 'ow_dashboard.views.user'),
)

Answer 1

你好像不在问你的实际问题。您提到的错误是因为如果用户是匿名的，您似乎将groups显式设置为空列表。但是你也很清楚你真正想要发生什么，即将用户发送到登录页面。那你为什么不问这个呢？

正如Raja所说，问题的解决方案是在视图上放置一个@login_required装饰器。

Answer 2

是的，和丹尼尔说的一样。你可以运行以下代码来获得结果。

＆＃13;

@login_required(login_url='/login/')
def user(request):
    groups = request.user.groups.all()
    if request.user.is_anonymous():
        groups = []
    dashboards = Dashboard.objects.filter(owner=groups)

    context = {
        'user': request.user,
        'groups': groups,
        'dashboards': dashboards,
    }
    return render_to_response('test2.html', context, context_instance=RequestContext(request))

＆＃13;

Django：int（）参数必须是字符串或数字，而不是＆＃39; list＆＃39;
