django 'User' object has no attribute 'get' 错误

Question

我正在编写一个简单的 Django 应用程序并陷入了这个错误，有人可以帮助我吗我的 views.py 和

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))

问题是我试图在 html 页面中显示登录的用户名。

这是我的错误回溯

urls.py 长得像

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'^login/$', 'django.contrib.auth.views.login',),
    url(r'^logout/$', '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>



{% endblock %}

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。 :)

你的问题不是 response，而是中间件正在获取一个 User 对象，所以在某处，你返回的不是响应而是用户，但我在你的代码中没有看到它。

不管怎样，你为什么不使用 django 的身份验证视图呢？他们做的事情与您尝试实施的事情相同。

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，将此添加到您的设置中：

LOGIN_REDIRECT_URL = '/dashboards/'

这是承诺的 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))
