用于视图的python日志装饰器

在django视图中,我有以下代码：

def view(request):
    try:
       # do stuff and return success case view response
       return render_to_response(...)
    except:
       # log the exception stack trace and return error case view response
       logger.error('...')
       return render_to_response('user friendly error message etc.')

我想将“try”除了块提取到装饰器.所以我写了类似下面的内容：

import logging.config
logging.config.fileConfig(LOGGING_CONFIG_FILE)
logger = logging.getLogger(__name__)   

def decorator(view):
    def inner(*args,**kwargs):
        try:            
            return view(*args,**kwargs)
        except:
            exception_traceback = traceback.format_exc(5)
            error_message = 'Exception:%s' % exception_traceback
            print 'Unexpected error occurred: %s' %(exception_traceback)
            logger.error( 'Unexpected error occurred: %s' %(exception_traceback))
            return render_to_response('error.json',{
                                'message': 'Unexpected system error occured - please contact system administrator'
                              },mimetype='text/plain')
    return inner

假设通常我也会在成功的情况下返回json.

由于某种原因,我的日志消息未显示在文件中. except子句中的“print”消息显示在控制台中.如果我在视图中使用日志消息,它会显示,因此日志记录配置正常.如果有人能指出这一点,我一定会错过一些简单的东西,我会很感激！

感谢名单！
