异常值:context必须是dict而不是WSGIRequest

Question

我正在使用Django 1.11,Apache 2.2和mod_wsgi制作一个使用Python 2.7的Web应用程序.我在渲染页面时遇到问题.完整的追溯是,

Environment:


Request Method: GET
Request URL: http://website.com/~user/irtf/

Django Version: 1.11.1
Python Version: 2.7.13
Installed Applications:
['irtf.apps.IrtfConfig',
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'mod_wsgi.server']
Installed Middleware:
['django.middleware.security.SecurityMiddleware',
 'django.contrib.sessions.middleware.SessionMiddleware',
 'django.middleware.common.CommonMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.contrib.messages.middleware.MessageMiddleware',
 'django.middleware.clickjacking.XFrameOptionsMiddleware']



Traceback:

File "/home/path/irtf_website/mysiteenv/lib/python2.7/site-packages/django/core/handlers/exception.py" in inner
  41.             response = get_response(request)

File "/home/path/irtf_website/mysiteenv/lib/python2.7/site-packages/django/template/context.py" in make_context
  287.         raise TypeError('context must be a dict rather than %s.' % context.__class__.__name__)

Exception Type: TypeError at /irtf/
Exception Value: context must be a dict rather than WSGIRequest.

我的views.py是,

def index(request):
        template = loader.get_template('irtf/index.html')

        return HttpResponse(template.render(request))

这可能没关系,但我的这个页面的模板只包含文本和链接.

这是因为第一个参数应该是字典.你可能把它与渲染捷径混在一起了

template = loader.get_template('irtf/index.html')
return HttpResponse( template.render({}, request))

要改为 使用渲染快捷方式

return render(request,'irtf/index.html')
