简单登录到django 1.3+的文件示例 [英] Simple Log to File example for django 1.3+
问题描述
发行说明说:
Django 1.3为Python的日志记录模块添加了框架级的
支持。
Django 1.3 adds framework-level support for Python’s logging module.
很好我想利用这一点。不幸的是,文档不会将它全部交给我在一个银盘上完整的工作示例代码的形式,演示了这是多么简单和有价值。
That's nice. I'd like to take advantage of that. Unfortunately the documentation doesn't hand it all to me on a silver platter in the form of complete working example code which demonstrates how simple and valuable this is.
如何设置这个时髦的新功能,以便我可以用
How do I set up this funky new feature such that I can pepper my code with
logging.debug('awesome stuff dude: %s' % somevar)
,并查看文件/tmp/application.log填写
and see the file "/tmp/application.log" fill up with
18:31:59 Apr 21 2011 awesome stuff dude: foobar
18:32:00 Apr 21 2011 awesome stuff dude: foobar
18:32:01 Apr 21 2011 awesome stuff dude: foobar
默认的Python日志记录与此框架级支持有什么区别? p>
What's the difference between the default Python logging and this 'framework-level support'?
推荐答案
我真的非常喜欢这里,这里是你的工作示例!认真的这是真棒!
I truly love this so much here is your working example! Seriously this is awesome!
开始把它放在你的 settings.py
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'standard': {
'format' : "[%(asctime)s] %(levelname)s [%(name)s:%(lineno)s] %(message)s",
'datefmt' : "%d/%b/%Y %H:%M:%S"
},
},
'handlers': {
'null': {
'level':'DEBUG',
'class':'django.utils.log.NullHandler',
},
'logfile': {
'level':'DEBUG',
'class':'logging.handlers.RotatingFileHandler',
'filename': SITE_ROOT + "/logfile",
'maxBytes': 50000,
'backupCount': 2,
'formatter': 'standard',
},
'console':{
'level':'INFO',
'class':'logging.StreamHandler',
'formatter': 'standard'
},
},
'loggers': {
'django': {
'handlers':['console'],
'propagate': True,
'level':'WARN',
},
'django.db.backends': {
'handlers': ['console'],
'level': 'DEBUG',
'propagate': False,
},
'MYAPP': {
'handlers': ['console', 'logfile'],
'level': 'DEBUG',
},
}
}
现在这是什么意思?
- 格式化器我喜欢它出现与./manage.py runserver相同的样式
- Formaters I like it to come out as the same style as ./manage.py runserver
- Handlers - I want two logs - a debug text file, and an info console. This allows me to really dig in (if needed) and look at a text file to see what happens under the hood.
- Loggers - Here is where we nail down what we want to log. In general django gets WARN and above - the exception (hence propagate) is the backends where I love to see the SQL calls since they can get crazy.. Last is my app were I have two handlers and push everything to it.
现在如何启用MYAPP使用它...
Now how do I enable MYAPP to use it...
按<一个href =https://docs.djangoproject.com/en/dev/topics/logging/#using-logging =noreferrer>文档将其放在文件的顶部(views.py )..
Per the documentation put this at the top of your files (views.py)..
import logging
log = logging.getLogger(__name__)
然后得到一些东西。
log.debug("Hey there it works!!")
log.info("Hey there it works!!")
log.warn("Hey there it works!!")
log.error("Hey there it works!!")
一个href =https://docs.djangoproject.com/en/dev/topics/logging/#making-logging-calls =noreferrer>这里和纯python 这里。
Log levels are explained here and for pure python here.
