mongodb - Using upsert with push to an array option on Ruby driver -

i'm trying upsert ruby driver mongodb. if row exist wish force new info , array, else create new document 1 item in array.

when run on mongodb looks that:

db.events.update( { "_id" : objectid("4f0ef9171d41c85a1b000001")}, { $push : { "events" : { "field_a" : 1 , "field_b" : "2"}}}, true)

and works.

when run on ruby looks that:

@col_events.update( { "_id" => bson::objectid.from_string("4f0ef9171d41c85a1b000001")}, { :$push => { "events" => { "field_a" => 1 , "field_b" => "2"}}}, :$upsert=>true)

and doesn't work. don't error don't see new rows either.

will appreciate help in understanding doing wrong.

so couple of issues.

in ruby, command should :upsert=>true. note there not $. docs here. you not running query :safe=>true. means exceptions not fire. causing exception on server, not waiting server acknowledge write.

ruby mongodb

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...
