我努力让一个cron工作工作并得到一个500错误。
我的app.yaml文件包含以下处理程序,因此它会选择代码
- url: /.*
script: main.application
这是我的cron.yaml
cron:
- description: my cron job
url: /daily_batch
schedule: every 10 minutes
main.py包含以下内容:
application = webapp2.WSGIApplication([
('/', MainPage),
('/daily_batch',DailyBatch),
], debug=True)
这就是我编写DailyBatch的方式
class DailyBatch ():
def get(self):
myDefaults = DefaultData.query().fetch()
for d in myDefaults:
counter = 0
如果我从一个网址运行它,它工作正常,但从cron给我一个500错误。我是愚蠢的。怎么样?
这是我得到的错误信息
