#mongodb logs for Friday the 28th of March, 2014
[02:15:06] <kongthap> hi, i'm reading doc at mongodb.org function and server-side javascript function are the same thing ?
[02:48:03] <pomke> On an update with upsert true, how would one set a 'created' timestamp only of the object is being created and not if it is being updated?
[02:58:42] <mongodb> Is there a way to see that "Get me all documents such that there's an element in array which is between 1 and 4?"
[05:06:14] <Froobly> hi. using mongoose, validations on my subdocument are running for every subdocument each time any of them is updated. is there a way to prevent this?
[05:06:46] <Froobly> i mean, is there a way to validate only one subdocument and not care if already saved ones break validation?
[09:14:58] <thearchitectnlog> can anyone help me with to query two related document into one embed document mongodb
[09:15:50] <thearchitectnlog> i have two related document with a foreign key i need to embed the child in the parent using a querry
[09:18:18] <thearchitectnlog> var child = db.child.find(); for (i=0;i<child.length();i++){var parent = db.parent.find({p_id: child[i].parent_id})[0].p_name;print(parent);}
[09:19:09] <thearchitectnlog> m getting the parent of the child i need to insert the child into the parent
[09:33:38] <thearchitectnlog> nodex just give me an example with any driver u want with just a parent and a child
[10:15:00] <ajph> hello. we've been having issues with a mongod instance stopping on one of our production servers. there's nothing in the log - it just stops. can anyone advise how i can further debug this issue?
[15:02:29] <Froobly> i mean, is there a way to validate only one subdocument and not care if already saved ones break validation?
[15:02:59] <Froobly> oops ;) i meant, using mongoose, validations on my subdocument are running for every subdocument each time any of them is updated. is there a way to validate only one subdocument and not care if already saved ones break validation?
[15:35:15] <davonrails> I’m trying to install mongo server on a server on which mongo client is already installed, the thing is I got a yum « conflits with » bug … Is there anyone who know how to solve that kind of thing ?
[17:10:13] <Froobly> using mongoose, validations on my subdocument are running for every subdocument each time any of them is updated. is there a way to validate only one subdocument and not care if already saved ones break validation?
[18:09:49] <laprice> I'm trying to add a user and keep getting " Error: couldn't add user: "createUser" command requires a "roles" array at src/mongo/shell/db.js:1007 "
[18:10:48] <laprice> The documentation on updgrading to 2.6 mentions that that is a difference, but this is a fresh install from the mongodb.org packages
[18:11:23] <hairyhenderson> Hi folks, I'm having some trouble with using a tailable cursor with the nodejs mongodb driver
[18:11:45] <laprice> Poking around the 2.6 docs doesn't give me any guidance as to where to create the "roles" array or what should be in it.
[18:12:06] <hairyhenderson> I'm using the cursor.stream() method and I don't seem to be getting any data events, even though I know documents are being added to the collection
[18:27:12] <proteneer> is there a reason not to put each collection in its own database to avoid the database level lock?
[18:27:34] <proteneer> i imagine sharding is one, as shards are only available at the collection level
[18:29:09] <cheeser> i have a gut feeling any performance gain you might get (and i doubt there's much) would be outweighed by the complexity of managing multiple DBs in one app.
[18:40:17] <jennr> ex. mongo -u username -p password --host theplaceiwant.com:27017/thatdb thejs.js > out.json
[20:10:30] <codygman> Are sparse indexes bad for nested data? I have some data that looks like {"value": "clicks": {"value": "thevalue"} I can't change and I'm trying to figure out how to access it somewhat efficiently.
[20:14:27] <durre> is there an easy way to set a new field in all document, to the value of another field on the document? I could do it with backend code
[20:27:48] <proteneer> waiting on a new version of motor, which is waiting on a new version of pymongo 2.7, which is waiting on a new mongo
[20:39:50] <harlanhaskins> I'm trying to write a query that'll find if a given device token exists in a user, within either 'ios' or 'android'.
[20:40:19] <harlanhaskins> So my query looks something like this: {'deviceTokens': {'$in': {'$or': [{'android': {'$in': ['Token']}}, {'ios': {'$in': ['Token']}}]}}}
[20:43:42] <proteneer> i have a gut feeling any performance gain you might get (and i doubt there's much) would be outweighed by the complexity of managing multiple DBs in one app.
[20:55:02] <skot> The changelog will contain a list of all chunks which are migrated between shards, if that is what you mean.

[20:56:59] <kongthap> hi, i'm reading doc at mongodb.org function and server-side javascript function, are they the same things ?
[20:58:47] <skot> It is hard to guess what you are reading so it is hard to know if they are the same thing. If I say yes, is that good or bad for you?
[20:59:45] <skot> maybe you can read this: http://docs.mongodb.org/manual/reference/command/eval/#dbcmd.eval
[21:31:08] <HSP40> I had a quick question: would it be better to have a seperate collection for comments on a post or a sub-document
[21:32:37] <tscanausa> sub document is faster access but there is a 16mb hard limit for any document
[21:37:30] <tscanausa> you would have to read the whole document out, delete the sub document attribute then write the sub document back
[22:44:26] <mylord> is this ok? db.turnys.update({"gId":"5335e4a7b8cf5123467890”}, {$addToSet:{"users":{"dId":"sys", "name":"sys"}}})
