#mongodb logs for Thursday the 1st of May, 2014
[00:02:15] <frodo_baggins> Hmm, Okay, here's another query I ran... https://gist.github.com/blafreniere/b16b78dc9824e35771f8
[00:18:57] <moleWork> how does one deal with: {"err":"connection to [<servername>] timed out"} errors?
[01:02:04] <frodo_baggins> So, it looks like my update call is working, but I need it to return the updated or inserted document.
[01:03:35] <frodo_baggins> But, it seemed that previously, I was able to have the result callback parameter be set to the document that was being updated, the complete document, so, if there's an option I can set to have that functionality, that would be awesome.
[01:12:27] <moleWork> it gives me an error on an insert {"err":"connection to [servername:27017] timed out"}
[01:12:27] <moleWork> so I've added retrylogic thinking the writeconcern meant that it didn't write to disk..... but it did write to disk cause the retry logic is getting duplicate key errors now so i'm not sure how to tell if something was written to disk or not... it most certainly isn't if(!err) on the insert callback
[01:14:35] <frodo_baggins> So it looks like the github documentation is more current than the website documentation...
[01:20:55] <frodo_baggins> I wish the node-mongodb-native driver API more closely corresponded to MongoDB's API.
[01:23:19] <moleWork> Disconnects can happen from time to time even without an aggressive firewall setup. Before you get into production you want to be sure to handle them correctly.
[01:27:47] <frodo_baggins> I have $inc incrementing a field called hitCount, and I have $setOnInsert initializing hitCount to 0 if it's not inserted.
[01:28:41] <frodo_baggins> I'm getting: MongoError: Cannot update 'hitCount' and 'hitCount' at the same time
[01:58:09] <moleWork> i think i found some simple logic to work around the issue, but it's like... umm... pretty shady
[02:01:47] <moleWork> this can't be the right logic for all situations but fixed my problem... basically result is not set, i get an err.err: " [servername:27017] timed out" but doc._id is set and the document is indeed written to the database
[03:15:41] <stratos13_> hey guys having a little problem here... I'm calling mongoDB with and the data I get back is like this: { year: 2005, VIN: 18048124, make: 'Toyota', model: 'Corolla', price: 123, ... etc
[03:16:09] <stratos13_> how do I get it to omit the ' (apostrophe) for the make and model variables
[07:22:57] <sobersabre> when I'm dropping a collection, do all its indexes get dropped as well, or do I have to run collection.drop_indexes() before dropping the collection ?
[10:04:53] <mylord> on mac, i get unknown user mongodb when trying this: sudo -u mongodb mongod --repair --dbpath /data/db/mongodb/
[10:08:15] <mylord> ya, i might have used brew.. looks like its owned by me.. -rwxr-xr-x 1 rover wheel 5 Apr 2 16:55 /data/db/mongod.lock
[10:17:26] <rspijker> ranman: I use OSX myself, never realized brew didn't install it under it's own user
[10:18:00] <ranman> rspijker: not the brew way, brew tries to do as much as possible without modifying the system
[13:01:15] <asturel_> anyone knows which package should i install on debian to have libmongoclient.so?
[14:01:03] <iphands> hey, I am starting a project where I hope to use mongo -> sleepy/drowsy -> AngularJS ... but I have some questions about where document level ACLs should be implemented
[14:01:54] <iphands> I suspect that I want to have mongo -> sleepy/drowsy -> some light layer to enforce document query restriction -> angular
[14:02:48] <iphands> but I wonder if sleepy or drowsy have already solved that by letting you "plug in" your own ACL "business logic"
[15:00:53] <Froobly> hi, i'm using another nosql db that has no way of renaming indexes within documents. i'm trying to rename a slug index for nicer routing. in one location i have a flat list of large objects in another document. when "renaming", i copy to the new index, and i create an alias { aliasOf: 'new-slug' } at the old one so that routing forwards with the old url. now rather than copy/delete the big tree of data, i was thinking about creat
[15:00:53] <Froobly> ing aliases for these in reverse, so that the new slug points to a new tree which is really an alias to the old tree. does anyone foresee any problems with this approach?
[15:48:04] <hallas> I have an aggregate pipeline that works awesomely. But! I would like to know if I can somehow combine the query it self an the explain option without running the query twice.
[15:48:34] <hallas> I wonna have the resulting documents, but also know how much I could get potentially (I have a $limit and $skip in my query)
[15:48:55] <hallas> So I can have pagination but also know how many pages there are in total. Can I do this without two seperate queries?
[16:21:39] <q85> hallas: no, adding explain to the query returns the explain document (even though it executes the query to generate the explain).
[17:50:58] <bobbytek> Figured it out: http://stackoverflow.com/questions/3987683/homebrew-install-specific-version-of-formula
[17:54:45] <asturel_> anyone knows there is no package for debian which contains mongoclient _shared_ library?
[17:55:22] <asturel_> the example on mongodb advised that link dynamic againts the lib now i screwed because on debian there is only static lib
[20:24:24] <daidoji> hello, is there a way to $sum with teh agg framework with values stored as strings?
[20:24:52] <daidoji> I've tried something similar to db.foo.agg(... {$sum : parseFloat('$FIELDNAME') } but its not working
[20:26:22] <daidoji> cheeser: :-( fair enough, is there a way to force a BSON type when I load? or do I just magic my way into the db ie) field + 0.0 or something?
[20:34:31] <garietyxxx> Hi, #mongodb, I'm building an app with multiple models with structure: Post, Photo, Event, etc.
[20:35:06] <garietyxxx> But I can't wrap my head around wether mongodb will work. Cause what if I want to query all those models form the database at once? I'd have to do three separate queries.
[20:36:51] <garietyxxx> But I have three different models, how can I query them all at the same time with mongo?
[20:38:22] <garietyxxx> It seems liek that suggests I coudl have a "Thing" model above all the others I can query.
[20:38:38] <cheeser> well, this is something you'll need to understand if you hope to make an intelligent, informed decision.
[20:41:24] <cheeser> 1. i don't have enough info to say. 2. i think i'd probably have a different model than you're describing but see #1
[20:48:24] <daidoji> garietyxxx: in mongodb your best bet is to denormalize (ie embed documents within eachother) if you have a data set with a bunch of joins you're better off with postgres probably
[20:48:41] <daidoji> unless you have a Lot with a capital L of joins in which case maybe a graph database would be best
[20:53:14] <daidoji> well I'm glad it makes sense to him, I'm still coming to grips with that after 5 professional years of data modeling
[21:17:24] <daidoji> q85: is there any reason a MapReduce would fail with NaN but succeed if I pass it a { query: { field: 'blah' } } filter?
[21:24:18] <daidoji> q85: its pretty simple, it passes if I pass it only like 2 documents with a { query } filter to mapReduce, but fails on the full dataset
[21:34:18] <daidoji> is it possibly related to this issue maybe? http://osdir.com/ml/mongodb-user/2011-02/msg00915.html
[21:43:15] <moleWork> is there any good examples of a node.js application that uses mongodb that is "production quality". Soon as I start load testing my app everything gets ugly really quick
[21:44:46] <moleWork> i think most are my problems with node.js monogo db driver and not mongodb itself
[21:48:03] <moleWork> it seems to me like you need a lot of error handling logic for every database operation because you can get a lot of random errors when the driver is in certain states
[21:50:06] <moleWork> it it doesn't seem to me like you can use the internal _state objects of the mongoclient or the db objects reliably
[23:33:47] <larkith> I added a new member to a rs today and now I'm getting "not master or secondary; cannot currently read from this replSet member" every hour from the app
