Useful decorator to handle exceptions with logging support and additional handlers if exception occurs.
Example 1:
def handler_function(need_error, result):
return (result, need_error)
@exception_handler(error_message='TEST',
additional_handler=handler_function)
def testing_func(need_error, result):
if not need_error:
return result
raise Exception('test')
testing_func(True, 1)Log output:
[EMSG: TEST]
[STACK:
[FILE: /home/decorators.py => FUNC: inner => LINE: 48]
[FILE: tests.py => FUNC: testing_func => LINE: 19]
]
[CONTEXT:
{'result': 1, 'need_error': True}
]
[DETAIL:
test

Example 2:
@exception_handler()
def only_err():
raise Exception('test')
only_err()Log output:
[EMSG: UNSET]
[STACK:
[FILE: /home/decorators.py => FUNC: inner => LINE: 48]
[FILE: tests.py => FUNC: only_err => LINE: 31]
]
[CONTEXT:

Example 3:
@exception_handler(error_message='TEST',
additional_handler=handler_function,
additional_log_data=lambda ne, res: str(res))
def testing_func_one(need_error, result):
if not need_error:
return result
raise Exception('test')
testing_func_one(False, 1)Log output:
[EMSG: TEST]
