Creating public area navigation helps users navigate a web page by making each subject a clickable link. In this video, you'll learn how to create public area navigation in Ruby on Rails 4, how to create a placeholder for this navigation, and how to include the code that will enable your web page to function as you like.
…In the last movie, we created a public controller…and enabled it to display pages from our CMS.…But in order to view those pages, we had…to type their permalink into the browser's URL bar.…Let's create a navigation for the public area, by listing the…available pages by subject, then each page will be a clickable link.…Users will be able to navigate our site, and…view different pages, just by clicking on those navigation links.…Let's start by going into our public controller.…And let's make sure that we have a…list of subjects available, for our navigation to display.…
So, for example, in our index, we could just say, @subjects.…And then come up with a subject list.…Subject, we want the visible ones and we…also want then to be sorted by their position.…Now we don't want it to just be for our index…page, though, we want it to also be for our show page.…Rather than repeat ourselves in both of them, this is…going to be a good case for putting it down here.…And we're going to make a private method…which is going to be called setup navigation.…
