I'm currently using MongoDB in a reporting system and have to delete a whole bunch of test documents. While I don't have too much trouble using the JSON-based command-line tools, it gets extremely tedious to have to keep searching for documents, copy-and-pasting OIDs, etc., especially from a command prompt window (ever tried to "mark" t...

For example, if I have the following documents: class Person include Mongoid::Document embeds_many :phone_numbers field :name end class PhoneNumner include Mongoid::Document embedded_in :person, :inverse_of => :phone_numb...

I've been trying to add to an array (or what ruby is saying is an array), but keep getting an error from mongo which says Cannot apply $addToSet modifier to non-array when I try to run User.collection.update({'id'=> current.id},{'$addToSet'=>{ 'following' => current.id}}) User.collection.update({'id'=> user.id},{'$addToSet'=...

Is there an easy way to get the ID (ObjectID) of the last inserted document of a mongoDB instance using the Java driver? ...
I saw this Q&A http://stackoverflow.com/questions/2900763/mongodb-norm-query-nested-objects, but it seems to apply to strongly-typed objects only. Is there a way to do a find or update a nested field on an Expando object (http://wiki.github.com/atheken/NoRM/expando)? Basically, I have a simple JSON CMS tool that lets developers store do...

Django-mongodb-engine is a django backend,you can use it with django ORM. So django-mongodb-engine is better? and how about its...
We have developed PaaS solution for PHP. As part of that we offer developers to see Apache error_log and access_log files through our API. Currently we write the logs into files on disk seperated per deployment (vhost). Since this doesn't scale too well with a higher number of nodes and deployments, even though files are on distributed...
Hi guys, I'm implementing blog based on MongoDB. Let's look at first how Mongo guys recommend us to store blog post and its comments (http://www.mongodb.org/display/DOCS/Schema+Design): posts should be a collection. comments should be embedded objects within a post for performance. I found that it is very difficult to edit or just ...
I'm not quite sure when I should use SingletonScope() vs TransientScope() vs RequestScope() when I do my binding in my global.cs file. I have for example my call to MongoSession (using NoRM and the mvcStarter project http://mvcstarter.codeplex.com/) which is set to SingletonScope but I created a repository that use this MongoSession obj...
I will be storing terabytes of information, before indexes, and after compression methods. Should I code up a Binary Tree Database by hand using sort files etc, or use something like MongoDB or even something like MySQL? I am worried about (space) cost per record with things like MySQL and other DB's that are around. I also know that ...
Authlogic, by itself, seems to be too active record centric for MongoDB (specifically mongomapper) as per: http://github.com/binarylogic/authlogic/issues#issue/15. However, there's an interesting authlogic plugin for mongo that looks pretty awesome, and simple. Has anyone used this, or have any experience/recommendations for an authlo...
I'm doing development on MongoDB. For totally non-evil purposes, I sometimes want to blow away everything in a database—that is, to delete every single collection, and whatever else might be lying around, and start from scratch. Is there a single line of code that will let me do this? Bonus points for giving both a MongoDB console method...
I'm trying MongoDB with NoRM in C# and can't figure out why my LINQ queries don't work. Something as simple as this: How can this return all documents with all the fields/properties populated: return Collection.FindAll().Documents.ToList(); but this one only returns the correct number of documents with only the ID field popul...
Hey Everyone, Let me explain my problem, and hopefully someone can offer some good advice. I am currently working on a web-app that stores information and meta-data for a large amount of applications. For each application there could be anywhere from 10 to 100's of comments that are tied to the application and an application version i...
I am a complete noob when it comes to the NoSQL movement. I have heard lots about MongoDB and CouchDB. I know there are differences between the two. Which do you recommend learning as a first step into the NoSQL world? ...
Does anyone have a good resource for MongoMapper documentation? I've been reading through the mongoDB docs, but a lot of it doesn't convert across to ruby/mm. I've been trying to figure out how to do a SELECT FROM WHERE EXISTS with little success. db.things.find( { a : { $exists : true } } ); // return object if a is present The only ...
