Hey, I'm very new to rails and have been trying to experiment with using Mongodb on a web app. I have been following this railscast tutorial here word for word and have been running into issues with it not connecting to my local Mongodb. I'm sure Mongodb is up and running since mongod shows up in my activity monitor and going to ht...
After some searches, I found the documentation of mongo_mapper is poor. There is only a short readme on GitHub, only one article in http://mongomapper.com, and just a list of classes in the RDoc. I know there is a good screencast at http://railscast.com, but I want some more good documents about how to using mongo_mapper. Are there an...
I properly installed MongoDB and got it running on my OSX. The first app I created using MongDB and Rails3 was titled 'todo". Per the instructions on railscasts, I created a file (config/initilializers/ mongo.rb) and added this line: MongoMapper.database = "todo- #{Rails.env}" Presumably, this created the files that appeared in my ...

I am just starting a new Rails 3 project using Mongoid ORM for MongoDB. There is just one thing I can not get my head around, and that is how to effectively have a many-to-many relationship. Now there is a good chance that I may be approaching this problem wrong, but as far as I know, there is at least two containers in my project that...
I would like to get machinist, machinist_mongo, mongo_mapper, cucumber and pickle to play nice together. Currently I have machinist with all my blueprints configured and am using cucumber to do BDD. So far so good. My problem is I am having to write custom cucumber steps for all of my machinist blueprints. It is not really a problem per...

I'm trying to implement Paperclip in my first rails app, and I happen to be using rails 3 and mongodb with mongomapper. I followed this guide on getting there things to all work together http://www.bencurtis.com/2009/08/paperclip-and-mongomapper/ Just as the blog post suggests, I've put paperclip into the config/initializers directory,...
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'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 ...

I'm trying to put together an association that takes advantage of Mongo's document subkey indexing. For example, I have two collections, posts and topics. Posts have a tags key, which is an indexed set of tags for the post - pretty vanilla. What I want to do though, is have something in my Topic model like: class Topic key :name, Stri...
