Question

我正在研究这个项目，顺便说一下，直到几秒钟之前。我在其中一个应用程序视图中添加了一个通用的详细信息视图，它向我发送Template not found error，但我清楚地指出了template_name并确保模板存在。我刷新了页面， BAM 我收到了此服务器错误。

回溯指示了两个文件，以下是代码片段：

general_views.py

def server_error_view(request, template_name='other/500.html', **kwargs):
    return render_to_response(template_name, 4, context_instance=RequestContext(request))

context_processors.py

def applications(request):
    if request.subdomain is not None: #This is where the error occured
        subdomain = str(request.subdomain)+'_'
    else:
        subdomain = ''

和middleware.py

class SubdomainMiddleware:
""" Make the subdomain publicly available to classes """    
def process_request(self, request):
    domain_parts = request.get_host().split('.')
    if (len(domain_parts) > 3):
        subdomain = domain_parts[0]
        if (subdomain.lower() == 'www'):
            subdomain = domain_parts[1]
        else:
            subdomain = None
        domain = '.'.join(domain_parts[2:])
    elif (len(domain_parts) > 2):
        subdomain = domain_parts[0]
        if (subdomain.lower() == 'www'):
            subdomain = None
        domain = '.'.join(domain_parts[1:])
    else:
        subdomain = None
        domain = request.get_host()
    request.subdomain = subdomain
    request.domain = domain

WSGIRequest对象没有属性'subdomain'
