python - Celery chain results from task to map to another -


i have celery application

@task def step_one(items):     items.sort()     in range(len(items), 100):         yield items[i:i + 100]  @task def step_two(batch):     item in batch:         print(item)  if __name__ == '__main__':     celery.chain(step_one.s([i in range 100000]), step_two.map().s()).delay()

this not work because step_two expecting iterator, want take results previous step, correct way go this? nice if tasks start @ yield rather after whole list sorted , chunked.

i have seen question best way map generated list task in celery feel should not necessary create intermediate step map results task. additionally, calling step_two.map.s() gives me error function object has no attribute s

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
