django'用户'对象没有属性'get'错误

Question

我正在编写一个简单的 django 应用程序并陷入此错误，请有人帮助我 我的 views.py 看起来完全一样

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

我的 forms.py 就像

from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
#from mhawk.models import Dashboard


class LoginForm(forms.Form):
        username        = forms.CharField(label=(u'User Name'))
        password        = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))

问题是我正在尝试在 html 页面中显示登录的用户名。

这是我的错误追溯

urls.py 看起来像

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

urlpatterns = patterns('',

    url(r'^admin/', include(admin.site.urls)),

    url(r'^logout/$', 'django.contrib.auth.views.logout'),
    url(r'^user/$', 'mhawk.views.User'),
)

dashboards.html:-

{% extends "base.html" %}
{% block content %}
{% if user.is_authenticated %}
    <p>Welcome, {{ request.user.get_username }}. <br/>
    {% else %}
    <p>Welcome, new user. Please log in.</p>
{% endif %}

<ul>
{% for group in groups %}
    <li>
        <strong>{{ group.name }}<strong> -
        
            {{ dashboards.d_name }}{% if not forloop.last %},{% endif %}
        
    </li>
{% endfor %}
</ul>

这是你的问题，在 url 中，你指向的不是视图，而是 User。 Python 区分大小写，你知道的。 :)

您的问题不是response，而是中间件正在获取User 对象，所以在某个地方，您返回的是用户而不是响应，但我在您的代码中看不到它。

不管怎样，你为什么不使用 django 的认证视图呢？他们做的事情和你试图实现的一样。

from django.contrib.auth.views import login, logout

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='/')

哦，是的，将其添加到您的设置中：

LOGIN_REDIRECT_URL = '/dashboards/'

这是一个承诺的user视图：

from django.contrib.auth.decorators import login_required

@login_required
def user(request):
    # btw 'user' variable is already available in templates
    context = {'user': request.user}
    return render_to_response('dashboards.html', context, context_instance=RequestContext(request))
