金字塔(Python):覆盖默认错误视图

Question

任务:当我的一个视图中发生错误时,我需要显示自定义错误视图.错误类型无关紧要.

我尝试通过registring查看所有异常来覆盖所有异常,如下所示:

<view
    context="Exception"
    renderer="server_error.pt"
    />

它运作良好.所有例外都显示了我的观点.但问题是那些错误停止了记录.在我的错误视图中,我可以执行类似logger.error(traceback)的操作,但这是一个愚蠢的想法.

如何在不破坏日志记录金字塔系统的情况下为所有错误注册视图.

Answer 1

您可以通过普通的旧 python 日志记录在视图中记录错误。或者将响应的状态设置为 500（假设您的视图现在返回状态 200，这表示响应成功）。

编辑：工作示例

我不是日志记录专家，但我的印象是，您在development.ini/Production.ini中的日志记录配置会被采纳，下面的示例似乎证明了这一点，但您是判断者......

更改默认日志配置

[formatter_generic]
# format = %(asctime)s %(levelname)-5.5s [%(name)s][%(threadName)s] %(message)s
format = y u no work??!!?? %(message)s
# End logging configuration

观点

from pyramid.view import view_config
from webob import Response
import logging
log = logging.getLogger(__name__)

@view_config(route_name='home', renderer='templates/mytemplate.pt')
def my_view(request):
    raise ValueError("oops")
    return {'project':'tstLogError'}


@view_config(context=Exception)
def exception_view(context, request):
    log.error("The error was: %s" % context, exc_info=(context))
    return Response(status_int=500, body=str(context))

    from pyramid.view import view_config
    from webob import Response

控制台输出：
