Every day,week,month,year in AppEngine cron (python)

I'm trying to set an appengine task to be repeated at midnight of every day, week, month, and year, for clearing a high score list for a game.

My cron.yaml looks like this:

- description: daily clear
  url: /delete?off=10
  schedule: every day 00:00
- description: weekly clear
  url: /delete?off=20
  schedule: e开发者_如何学Pythonvery monday 00:00
- description: monthly clear
  url: /delete?off=30
  schedule: every month 00:00
- description: yearly clear
  url: /delete?off=40
  schedule: every year 00:00

Daily and weekly jobs are OK, but I can't figure out how to make a job repeat every month and year. This is the schedule format.

For each month job, I've tried expressions like 'every month', '1st of month', etc, but nothing did work. Is this type of schedule possible in cron jobs?

Or do I need to just invoke the clearing page just daily at 00:00, and do this logic in page and test current date, if it's the start of week/month/year?

The docs you link to give examples of how you could achieve all of the results you want.

# Daily:
every day 00:00

# Weekly:
every monday 00:00

# Monthly:
1 of month 00:00

# Yearly:
1 of jan 00:00

I would go with something like this:

- description: daily clear
  url: /delete/daily
  schedule: every day 00:00
- description: weekly clear
  url: /delete/weekly
  schedule: every monday 00:00
- description: monthly clear
  url: /delete/monthly
  schedule: first of month 00:00
- description: yearly clear
  url: /delete/yearly
  schedule: first of jan 00:00

AFAIK you can't use a syntax like this /delete?off=30 in yaml but you need to define a route explicitly for every different clear with /delete/weekly for example
