The title pretty much says it all: Has MongoDB ever been compiled to work on iOS devices? I know the terms of the App Store do not allow an application to launch a subprocess, so the DBDirectClient class would have to be used to access the data files in-process. Any thoughts? ...
Hi, I have the following MongoDB object stored in my Mongo database: array ( '_id' => new MongoId("4cc183de48aa4c7708000000"), 'vehicleMake' => 'Volkswagen', 'vehicleModel' => 'Carrier', 'vehicleNumPassengers' => '7', 'vehicleReg' => '07-D-748393', 'coords' => array ( 0 => array ( 'lat' => '53.2594946', ...

so i'm new to this whole NOSQL stuff and have recently been intrigued with mongoDB. i'm creating a new website from scratch and decided to go with MONGODB/NORM (for C#) as my only database. i've been reading up a lot about how to properly design your document model database and i think for the most part i have my design worked out pret...
Im thinking about doing the following and need suggestions if it makes sense to approach it this way. Basically since I am able to do queries in MongoDB and MongoDb is wicked fast at these since the hotspots of the data are cached in memory. I was thinking of storing data I would normally do a join from in mysql in mongoDB. While I am us...
Let's take a simple example, a blog post. I would store comments to a particular post within the same document. messages = { '_id' : ObjectId("4cc179886c0d49bf9424fc74"), 'title' : 'Hello world', 'comments' : [ { 'user_id' : ObjectId("4cc179886c0d49bf9424fc74"), 'comment' : 'hello...
I want update an _id MongoDB of one document. I know it's not a really good pratice. But with some technical reason, I need update it. But If I try to update it I have : > db.clients.update({'_id':ObjectId("4cc45467c55f4d2d2a000002")}, {'$set':{'_id':ObjectId("4c8a331bda76c559ef000004")}}); Mod on _id not allowed And the update is not...

Is it possible to use the Java MongoDB driver to run queries in the same syntax as MongoDB shell from Java code? Something like, for example, DBCursor cursor = mongo.runQuery("db.things.find();"); ...
I have a rake task that processes a set of records and saves it in another collection: batch = [] Record.where(:type => 'a').each do |r| batch << make_score(r) if batch.size %100 == 0 Score.collection.insert(batch) batch = [] end end I'm processing about 100K records at a time. Unfortunately at 20 minutes, ...
Let's say there is: {username : "tom1", address : { type : 0, year : 2001 }} {username : "tom2", address : { type : 1, year : 2011 }} {username : "tom3", address : { type : 0, year : 2031 }} {username : "tom4", address : { type : 1, year : 2002 }} I'm using Java Driver, how can I query: users who's address.type = 1 AND address.year > ...
I need to import (restore) a collection generated with mongodump into an existing database and I'd like the records to be merged into the existing collection. Does mongorestore merge the records in the same collection or it will drop the existing collection before restoring the records? ...
I'm using Map Reduce with MongoDB. Simplified scenario: There are users, items and things. Items include any number of things. Each user can rate things. Map reduce is used to calculate the aggregate rating for each user on each item. It's a complex formula using the ratings for each thing in the item and the time of day - it's not ...
I know that in the MongoDB terminal, I can run "show dbs" to see the available databases. I want to get them programmatically so that I can iterate over them and delete some based upon a regular expression. I have tried db.runCommand("show dbs") but that doesn't work. Thanks in advance. ...
Back-Story On a current project, I am using MySQL and SQLite in combination with each other. I'm currently giving each user their own SQLite database to get around my provider's 1GB MySQL DB limit. It's worked out alright and the performance is good, but I know for a fact that continual maintenance of these flat-file databases will be a...
Hi! I am not deep in working with MongoDB. But i want to use it with C# driver. I guess that not all features can be available in this driver (Am i right?). Or for example, it easy to find some code written on javascript and, so, it seems easy to use it without mapping/finding appropriate methods in C# driver. I know that MongoDB is wri...

I'm making an app that uses the classic "follow" mechanism (the one used by Twitter and a lot of other apps around the web). I'm using MongoDB. My system has a difference, though: an user can follow groups of users. That means that if you follow a group, you'll automatically follow all the users who are members of that group. Of course ...
I have a Rails 3 project that does file upload/download, with access rights (User has many Files, and can only read/write his own files). If I store my files on classic filesystem, I can check the access to the file in my rails app and then use X-Sendfile header to redirect to the file, if user has access. In this way, a user can neve...
