I have a Rails 4.2 app. I want to create a script in the lib folder that I will use to create records in my database. So hypothetically:

lib/user_builder.rb

require 'rubygems'
require 'active_record'
require './app/models/application_record.rb'
require './app/models/client.rb'

module UserTheory
 class UserBuilder
 def initialize
 user = User.find_or_initialize_by(id: 1)
 user.name = 'Bob'
 user.save
 end
 end
end 

I required those files because I was getting NameErrors about those classes. Now I am getting another error:

/usr/local/bundle/gems/activerecord-4.2.10/lib/active_record/connection_adapters/abstract/connection_pool.rb:570:in `retrieve_connection': No connection pool for User (ActiveRecord::ConnectionNotEstablished)

so clearly I am going about this the wrong way.

  instead of putting it in lib, try a directory inside app/ such as app/services. Then you shouldn't need the requires and autoloading should work properly.

  Why aren't you just using the db/seeds.rb file?
