问题描述

当我追加 - traceback --verbosity 2 时，Django的 runserver 命令不会输出堆栈跟踪：

 ➫python manage.py runserver --traceback --verbosity 2

 Django版本1.5.1，使用设置'base.settings'
开发服务器运行在http： /127.0.0.1:8000/ 
使用CONTROL-C退出服务器。 
 [24 / Jul / 2013 11:45:27]POST / login / get_associations / HTTP / 1.0500 13220 
  

有没有其他命令行开关或记录配置，我可以添加以获取 runserver 打印一个堆栈跟踪，当有一个 500 ？

解决方案

同意这样很方便，特别是以MVVM为中心的应用程序开发角/琥珀色前端）。另外这有助于其他人测试前端。

正如你所提到的，这不是由 DEBUG = True 。您可以通过在 settings.py 文件中添加以下内容来运行 ./ manage.py runserver 添加一个堆栈跟踪：

  LOGGING = {
'version'：1，
'handlers'：{
'console'：{
'level'：'DEBUG'，
'class'：'logging.StreamHandler'，
}，
}，
' '：{
'django.request'：{
'handlers'：['console']，
'propagate'：True，
'level'：'DEBUG' 
} 
}，
} 
  

此语法来自Django文档，并可进一步修改以增加或减少控制台的数量记录。

另请注意， 5XX 的回复提高为ERROR我ssages和 4XX 响应作为警告消息引发。

Django version 1.5.1, using settings 'base.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Are there other command line switches or logging configuration I can add to get runserver to print a stack trace when there is a 500?

解决方案

Agreed that this is convenient, especially for MVVM-centric app development (e.g. Angular/Ember front-end). Also this is helpful when others are testing out the front-end.

As you mentioned, this isn't provided by DEBUG=True. You can add a stacktrace when running ./manage.py runserver by adding the following to the settings.py file:

LOGGING = {
    'version': 1,
    'handlers': {
        'console':{
            'level':'DEBUG',
            'class':'logging.StreamHandler',
        },
    },
    'loggers': {
        'django.request': {
            'handlers':['console'],
            'propagate': True,
            'level':'DEBUG',
        }
    },
}

This syntax comes from the Django documentation Configuring Logging and can be further modified to increase or decrease the amount of console-logging.

Also note that 5XX responses are raised as ERROR messages and 4XX responses are raised as WARNING messages.
