我在Django中实现了自定义命令,它们的异常没有记录在我的日志文件中。
我创建了一个应用程序my_app_with_commands
,其中包含一个目录management/commands
,其中我实现了一些命令。
示例命令可能是这样的,由于异常而崩溃:
import logging
from django.core.management.base import BaseCommand
class Command(BaseCommand):
help = 'Do something usful'
log = logging.getLogger(__name__)
def handle(self, *args, **options):
self.log.info('Starting...')
raise RuntimeError('Something bad happened')
self.log.info('Done.')
我的日志配置如下:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'formatters': {
'normal': {
'format': '%(asctime)s %(module)s %(levelname)s %(message)s',
}
},
'handlers': {
'file': {
'level': 'INFO',
'class': 'logging.FileHandler',
'filename': os.path.join(BASE_DIR, '..', 'logs', 'my_log.log'),
'formatter': 'normal',
},
'mail_admins': {
'level': 'ERROR',
'class': 'django.utils.log.AdminEmailHandler',
'include_html': True,
}
},
'loggers': {
'django': {
'handlers': ['file'],
'level': 'INFO',
'propagate': True,
},
'my_app_with_commands': {
'handlers': ['file', 'mail_admins'],
'level': 'INFO',
'propagate': True,
},
},
}
当我运行该命令时,对记录器的调用已成功保存到my_log.log
文件:
2016-09-22 11:37:01,514 test INFO Starting...
但每个回溯的异常都会显示在调用命令的stderr
中:
[mgarcia@localhost src]$ ./manage.py test
Traceback (most recent call last):
File "./manage.py", line 10, in <module>
execute_from_command_line(sys.argv)

utility.execute()

File "/home/mgarcia/anaconda3/envs/my_env/lib/python3.5/site-packages/django/core/management/base.py", line 399, in execute
output = self.handle(*args, **options)
File "/home/mgarcia/my_project/src/my_app_with_commands/management/commands/test_command.py", line 11, in handle
raise RuntimeError('Something bad happened')
RuntimeError: Something bad happened
我可以在每个命令中实现try/except
块,并手动记录异常。但是我可以使用Django设置捕获异常并将其保存到我的日志文件而不是stderr
吗?
答案 0 :(得分:0)
其中一种方法 - 您可以修改 manage.py 文件以在其中添加try / except块:
log = logging.getLogger('my_app_with_commands')
# ...
try:
execute_from_command_line(sys.argv)
except Exception as e:
log.error('your exception log')
raise e
