Mysql2::Error: Table 'biller_development.employees_projects' doesn't exist: SHOW FULL FIELDS FROM `employees_projects`

Hi there, I am stuck on this error @6:51 of this stage. ("Has and Belongs to Many") After I type in the following; $rails c $p = Project.first $p.employees I then get the below error;

2.2.1 :001 > p = Project.first Project Load (0.4ms) SELECT projects.* FROM projects ORDER BY projects.id ASC LIMIT 1 => #<Project id: 1, name: "Death Star", customer_id: 1, created_at: "2015-09-19 03:58:55", updated_at: "2015-09-19 03:58:55"> 2.2.1 :002 > p.employees Mysql2::Error: Table 'biller_development.employees_projects' doesn't exist: SHOW FULL FIELDS FROM employees_projects ActiveRecord::StatementInvalid: Mysql2::Error: Table 'biller_development.employees_projects' doesn't exist: SHOW FULL FIELDS FROM employees_projects from /Users/feniannoakes/.rvm/gems/ruby-2.2.1/gems/activerecord-4.2.1/lib/active_record/connection_adapters/abstract_mysql_adapter.rb:299:in `query'

I then exited from the console - and tried; $rake db:migrate but that didn't help.

I have loaded my code onto gihub

Any help would be greatly appreciated. Thanks
