Rack:GridFS is a Rack middleware for creating HTTP endpoints for files stored in MongoDB's GridFS. You can configure a prefix string which will be used to match the path of a request and supply an id for looking up the file in the GridFS store.
GET '/gridfs/someobjectid-filename' EX. '/gridfs/4ccd0baa4d54340824000003-avatar.gif'
If the prefix is “gridfs”, then the id will be be “someobjectid”.
Mongo Driver Compatibility Notes
This version is currently based off of mongo-0.20.1.
As of mongo-0.19.1, there have been significant changes to GridFS. I do not plan to support versions of the mongo driver prior to 0.19. There are some compatibility issues with mongo-0.19 vs. mongo-0.20 (Mongo::ObjectId vs. BSON::ObjectId). For now, I am choosing to support mongo-0.20.
sudo gem install skinandbones-rack-gridfs --source=http://gems.github.com
require 'rack/gridfs' use Rack::GridFS, :hostname => 'localhost', :port => 27017, :database => 'test', :prefix => 'gridfs'
You must specify MongoDB database details:
hostname: the hostname/IP where the MongoDB server is running. Default 'localhost'.
port: the port of the MongoDB server. Default 27017.
database: the MongoDB database to connect to.
prefix: a string used to match against incoming paths and route to through the middleware. Default 'gridfs'.
