ErrorHandler

This is a handler for the python standard logging framework that can be used to tell whether messages have been logged at or above a certain level.

This can be useful when wanting to ensure that no errors have been logged before committing data back to a database.

As an example, first, you set up the error handler:

>>> from errorhandler import ErrorHandler
>>> e = ErrorHandler()

Then you can log and check the handler at any point to see if it has been triggered:

>>> e.fired
False
>>> from logging import getLogger
>>> logger = getLogger()
>>> logger.error('an error')
>>> e.fired
True

You can use the fired attribute to only perform actions when no errors have been logged:

>>> if e.fired:
...   print "Not updating files as errors have occurred"
Not updating files as errors have occurred

Installation

Do the following in your virtualenv:

pip install errorhandler
