How to make the tests pass in an elegant way? Ruby on Rails

I am writing a rails app with my colleague who wrote a lot of the tests. He had to take a leave of absence due to a death in his family, and I am needing helps with changing the model so that the tests will pass in our spec file.

Here is the model:

    class Worker < ActiveRecord::Base       attr_accessible :first_name, :last_name

      has_many :writings     end

Here is the spec:

    require 'spec_helper.rb'

    describe Worker do       describe "merging two workers" do         before(:each) do           @writing1 = Writing.create!(:writing_text => "Winner's note")           @writing2 = Writing.create!(:writing_text => "Loser's note")

          @winner = Worker.create!(:first_name => "Jim", :last_name => "Sullivan", :email => "winner@gmail.com")           @winner.writings << @writing1

          @loser = Worker.create!(:first_name => "Tom", :last_name => "Smithe"           @loser.writings << @writing2

          @result = Worker.merge(@winner, @loser)         end

        it "should return the winner" do           @result.id.should eq @winner.id         end

        it "should not edit the winner's name" do           @result.first_name.should eq @winner.first_name           @result.last_name.should eq @winner.last_name         end     end     end

All of these tests are failing, and I'm not sure what to do. I don't want to try something and accidentally break the model, as I am new to ruby on rails. Thanks.

Edit: Fails:
