The only tricky part of the implementation is realizing that we need to add two new actions to the Users controller; based on the routes defined in Listing 11.18, we need to call them following and followers. Each action needs to set a title, find the user, retrieve either @user.followed_users or @user.followers (in paginated form), and then render the page. The result appears in Listing 11.30.

Note here that both actions make an explicit call to render, in this case rendering a view called show_follow, which we must create. The reason for the common view is that the ERb is nearly identical for the two cases, and Listing 11.31 covers them both.
