Adding Post Likes Functionality

1. Type generate migration CreatePostLikesTable into the command line this creates the db/migrate ruby file

2. In the migrate file is a class called CreatePostLikesTable with a blank method called change in it. We added the following lines to the change method create_join_table :posts, :users rename_table :posts_users, :postslikes

3. Type rake db:migrate into the command line to create the table

4. Now we need to create the controller and we do this by typing bin/rails generate controller PostsLikes
