Question

I set up a project level RVM gemset for a sinatra app I am starting that will connect to a local database with Active Record. In order to test it I tried to run the below test app:

test.rb

require 'rubygems' # may not be needed, depending on platform
require 'sinatra'
require 'activerecord'

class Article < ActiveRecord::Base
end

get '/' do
  Test.establish_connection(
    :adapter => "sqlite3",
    :database => "hw.db"
  )
  Test.first.content
end

(Taken from the answer to this question: What's the best way to talk to a database while using Sinatra?)

When I run ruby -rubygems test.rb I get this error:

/Users/[user]/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- activerecord (LoadError)

I’ve already installed the Active Record gem and it shows up in gem list and rvm current displays the correct gemset. I am new to RVM and I think this is something to do with the it not having the correct load path but I feel like I’ve set everything up correctly so I’d appreciate suggestions on what’s wrong. Thanks.

As far as I can tell require ‘activerecord’ has been deprecated. Try using

require 'active_record'

instead.
