You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: data_mapper.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/orm_adapter-0.5.0/lib/orm_adapter/adapters
    
    the code of the file until where you have to start completion: require 'dm-core'

module DataMapper
  module Model
    include OrmAdapter::ToAdapter
  end

  module Resource
    class OrmAdapter < ::OrmAdapter::Base
      # get a list of column
    
      def find_all(options = {})
        conditions, order, limit, offset = extract_conditions!(options)
        opts = { :conditions => conditions, :order => order_clause(order) }
        opts = opts.merge({ :limit => limit }) unless limit.nil?
        opts = opts.merge({ :offset => offset }) unless offset.nil?
        klass.all opts
      end
