Mongo Uploader

simple attachment handler to ActiveRecord wich stores files in MongoDB

Usage

Generating the Initializer

rails generate mongo_uploader:config

Options:

MongoUploader::Base.configure do

  # MongoDB database
  config.db = "app"
  
  # MongoDB host
  config.host = "localhost"

  # if your MongoDB requires authentication
  #
  # config.user = "username"
  # config.password = "password"

  # prefix used by the middleware to redirect the requests to MongoDB
  #
  # config.url_prefix = "mongo"
end

In your model:

mongo_attachment :file

you should have a String column named file in your database.

Middleware

The files will be served through a middleware directly from MongoDB.

You can use the #{column}_url method (file_url in the previous example) to get the url. This url will be something like:

http://my_app.com/mongo/4ebd9286a17d735dbc000001/image_223.jpg
