payment gateway - Paypal Sanbox - IPN Not working -

my site not receiving ipn paypal sandbox. verified working of notify.php page sending manual ipn via "ipn simulator" , works fine. receiving no ipn regular purchase simulation.

i checked ipn history sandbox-test account. ipn end in failed after multiple retries.

1/30/2012 22:47 pst | 8uy41985u65227626 | failed | 7um32625t8929325l

1/30/2012 22:32 pst | 36444784fh458323t | sent | 7l3718344f253661j

1/30/2012 22:28 pst | 5ka14796r82961455 | failed | 9pu30039g7583750s

i can't figure out issue! problem @ end or wrong @ sandbox overloaded or etc.?

there no guaranty ipn work sandbox each time. responses can returned after few hours or never.

also, sure that:

your homecoming url public (not in local network "localhost") does not have port number is not behind firewalls, routers etc (accessible anywhere internet) your script should not have errors. utilize logging or send email in origin of script go paypal seller business relationship profile ->selling preferences ->instant payment notification preferences, , confirm url correct

for final test, utilize real paypal accounts , send little amount of money test.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
