Getting started with the Friendly ORM

Question

I'm following this tutorial: http://friendlyorm.com/

I'm using InstantRails to run MySQL locally. To run Ruby and Rails, I'm using normal Windows installations.

When I run Friendly.create_tables! I only get an empty Array returned: => [] and no tables are created in my 'friendly_development' database.

Author of Friendly here.

You'll have to require all of your models before calling Friendly.create_tables! Otherwise, there's no way for Friendly to know which models exist. In a future revision, I'll automatically preload all your models.

how do I do that? Require 'CamelCasedModelName'? – user94154 Dec 23 '09 at 23:49

I have a rake task, with help from a guy called Sutto, that will load in all your models and then call Friendly.create_tables! and print out all the tables involved.

namespace :friends do
  desc "load in all the models and create the tables"
  task :create => :environment do
    puts "-----------------------------------------------"
    Dir[Rails.root.join("app", "models", "*.rb")].each { |f|File.basename(f, ".rb").classify.constantize }
    tables = Friendly.create_tables!
    tables.each do |table|
      puts "Table '#{table}'"
    end
    puts "-----------------------------------------------"
  end
end

rake friends:create

not much to go on here. My guess is that it can't find your model file that you are creating in the path?
