Django 1.4本地500错误页面

Question

由于使用DEBUG = True和TEMPLATE_DEBUG = True移动到Django 1.4，当我在本地遇到错误时，我不再看到带回溯的典型黄色错误屏幕。相反，我会看到一个普通的白色屏幕，上面写着“出现错误，请检查日志......”。这是新的行为还是我通过组合1.3和1.4文件和设置搞砸了一些东西。

下面是一个example of my local settings.

错误处理 位于django.core.handler.base尝试调试handle_uncaught_exception功能。

def handle_uncaught_exception(self, request, resolver, exc_info): 
    """ 
    Processing for any otherwise uncaught exceptions (those that will 
    generate HTTP 500 responses). Can be overridden by subclasses who want 
    customised 500 handling. 

    Be *very* careful when overriding this because the error could be 
    caused by anything, so assuming something like the database is always 
    available would be an error. 
    """ 
    from django.conf import settings 

    if settings.DEBUG_PROPAGATE_EXCEPTIONS: 
     raise 

    logger.error('Internal Server Error: %s', request.path, 
     exc_info=exc_info, 
     extra={ 
      'status_code': 500, 
      'request': request 
     } 
    ) 

    if settings.DEBUG: 
     from django.views import debug 

检查，如果你路过这里 回报debug.technical_500_response（请求，* exc_info）

# If Http500 handler is not installed, re-raise last exception 
    if resolver.urlconf_module is None: 
     raise exc_info[1], None, exc_info[2] 
    # Return an HttpResponse that displays a friendly error message. 
    callback, param_dict = resolver.resolve500() 
    return callback(request, **param_dict) 

检查与您在debug.technical_500_response
