django'User'对象没有属性'get'错误 [英] django 'User' object has no attribute 'get' error

问题描述

我正在写一个简单的django应用程序，并被困在这个错误，可以有一个请帮助我
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）） 

和我的forms.py就像

  from django import forms 
 from django.contrib.auth.models import User来自dja的
 ngo.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））
  

，而我正在尝试在html页面中显示登录用户名。

这里是我的追踪错误

 环境：
 
 
请求方法：POST 
请求URL：http://127.0.0.1:8000/user/ 
 
 Django版本：1.7.3 
 Python版本：2.7.3 
安装的应用程序：
（'django.contrib.admin'，
'django.contrib.auth'，
'django.contrib.contenttypes'，
'django.contrib.sessions'，
 'django.contrib.messages'，
'django.contrib.staticfiles'，
'mhawk'）
安装的中间件：
（'django.contrib.sessions.middleware.Sessi onMiddleware'，
'django.middleware.common.CommonMiddleware'，
'django.middleware.csrf.CsrfViewMiddleware'，
'django.contrib.auth.middleware.AuthenticationMiddleware'，
'django.contrib.auth.middleware.SessionAuthenticationMiddleware'，
'django.contrib.messages.middleware.MessageMiddleware'，
'django.middleware.clickjacking.XFrameOptionsMiddleware'）
 
 
追溯：
文件/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.pyin get_response 
 204. response = middleware_method（请求，响应）
在process_response 
中的文件/usr/local/lib/python2.7/dist-packages/django/middleware/clickjacking.py31.如果response.get（'X-Frame -Options'，None）不是None：
 
异常类型：/ user / 
中的AttributeError异常值：'User'对象没有属性'get'
  

urls.py看起来像

 从django.c onf.urls导入模式，包括来自django.contrib的url 
从饮酒者导入视图导入管理
，模型
从django.contrib.auth.models导入用户
 
 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 ： -

< pre class =snippet-code-html lang-html prettyprint-override> {％extendsbase.html％} {％block content％} {％if user.is_authenticated％}< p> ;欢迎，{{request.user.get_username}}。 <峰; br /> {％else％}< p>欢迎，新用户。请登录。< / p> {％endif％}< ul> {％for group in groups％}< li> < strong> {{group.name}}< strong> - {{dashboards.d_name}} {％if not forloop.last％}，{％endif％}< / li> {％endfor％}< / ul> {％endblock％}

解决方案

有你的问题，在网址中，你指向的不是视图，而是指向用户。 你知道Python是区分大小写的。 $）

您的问题不是响应，中间件是得到一个用户对象，所以在任何地方，而不是回复你返回一个用户，我没有看到它在代码中。

无论如何，为什么不使用django的身份验证视图？他们做的是同样的东西，你试图实现。

 从django.contrib.auth.views导入登录，注销
 
 def custom_login（request）：
如果request.user.is_authenticated（）：
返回HttpResponseRedirect（'dashboards'）
返回登录（request，'login.html' authentication_form = LoginForm）
 
 def custom_logout（request）：
 return logout（request，next_page ='/'）
  

哦，是的，并将其添加到您的设置中：

  LOGIN_REDIRECT_URL ='/仪表板/'
  

这里是一个承诺的用户查看：

  from django.contrib.auth.decorators import login_required 
 
 @login_required 
 def user（request）：
＃btw'user'变量已经在模板中可用
 context = {'user'：request.user} 
 return render_to_response（'dashboards.html'上下文，context_in stance = RequestContext（request））
  

I am writing an simple django application and got stuck into this error, can some one please help me my views.py looks exactly as

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))

and my forms.py is like

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))

and the thing is I am trying to display the logged in username in an html page.

here is my trace back of error

解决方案

Edit

There is your problem, in urls, you are pointing not to a view, but to a User. Python is case sensitive, you know. :)

---

Your problem is instead of response, middleware is getting a User object, so somwhere, instead of response you are returning a user, I don't see it in your code though.

Regardless, why don't you use django's authentication views? They do same stuff as you are trying to implement.

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='/')

Oh yeah, and add this to your settings:

LOGIN_REDIRECT_URL = '/dashboards/'

And here is a promised user view:

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))
