Text printed to stderr may appear in the httpd error log when run under mod_wsgi. You can either use print directly or use logging instead.

  print >> sys.stderr, 'Goodbye cruel world!'

Here is a solution based on Django logging. It uses the DEBUG method instead of checking if you are on a development server or not, but if you can find a better way to find out, it should be easy to adapt.

  LOGGING =    'Version 1,    'Former' :        'detail':            'format': '% (level name) s% (asctime) s% (module) s% (process) d% (stream) d% (message) s'        ,        'Light':            'format': '% (level name) s% (message) s'        ,    ,    "Administrator":        'Console':            'level': 'DEBUG',            'Class': 'logging.StreamHandler',            'trainer': 'simple'        ,        "To file":            'level': 'DEBUG',           'Class': 'logging.FileHandler',            'File name': '/Path/to/Your/Fichier.log',            'trainer': 'simple'        ,    ,    "Recorder":        'Django':            "Manager": ["File"],            'level': 'DEBUG',            'distribute': ok,        ,    if DEBUGGING:    The number allows all registrars to use the console.    for loggers in LOGGING ['loggers']:        LOGGING ['loggers'] [loggers] ['handlers'] = ['console']

  if DEBUGGING:    The number will be displayed on your console    Logging.basicConfig (        Log level = .DEBUG,        the format implies '% (asctime) s% (levelname) s% (message) s',    )another:    # is printed to help save the file    Logging.basicConfig (        Logging = .DEBUG,        format '% (asctime) s =% (levelname) s% (message) s',        File name = '/my_journal_file.log',        File mode = 'a'    ) 

It depends on how decisive DEBUG is, and maybe you don’t need to worry about how it’s built. See this answer to the question How do I know if my Django app is in development on the server or not? available for better spelling if needed. Edit: The above example is taken from the complete Django 1.1 project, reference configurationlog in Django has changed slightly from the version.

  [recorder]keys = root, application log[Administrator]keys = rotateFileHandler, rotateConsoleHandler[Former]keys = applog_format, console_format[formatter_applog_format]format =% (asctime) s - [% (levelname) -8s]:% (message) s[format_console_format]format =% (asctime) s -% (filename) s% (linen) d [% (levelname) s]:% (message) s[logger_root]level = DEBUGhandlers = rotateFileHandler, rotateConsoleHandler[logger_applog]level = DEBUGhandlers = rotateFileHandlerqualname = simple_example[handler_rotateFileHandler]class = handlers.RotatingFileHandlerlevel = DEBUGtrainer = applog_formatargs = ('applog.log', 'a', 10000, 9)[handler_rotateConsoleHandler]class = StreamHandlerlevel = DEBUGtrainer = console_formatargs = (sys.stdout,) 

  Import loggingImport Logging.configmain def ():    Logging.config.fileConfig ('logging.conf')   The logger is the same as Logging.getLogger ('applog')    logger.debug ("bug fix message")    logger.info ("informational message")    logger.warn ('warning message')    voice recorder message ') error ('error logger.critical (' critical message ')    # record.stop ()if __name__ == '__main__':    above all()

Whereas a regular Python module writes to a file topic opened in add mode, for example the App Engine module (https://github.com/dorkitude/tagalog/blob/master/tagalog_appengine.py) overrides this behavior and See also Logging used.INFO .Get

To change this behavior in any good App Engine project, you can easily do the following:

Import

  tagalog.tagalog_appengine as tagalogtagalog.log ('whatever the message', ['whatever', 'tags']) 

You can stretch the module yourself and crush the wood without much difficulty.

This task is good enough in my local.py, saving me from doing regular maintenance Magazine:

  from .settings *LOG ['managers'] ['console'] scan =    'level': 'DEBUG',    'Class': 'logging.StreamHandler',    'trainer': 'detailed'LOG ['loggers'] ['foo.bar'] =    "Manager": ["Console"],    'spread': false    'level': 'DEBUG',
