Course Syllabus
A Route to an Index Action
In the first stage, we'll read all Page records in the database and display their titles in a list. (Since we won't yet have a form for adding Pages, we'll have to add some via the Rails console.) This first stage will be the most involved, since we'll need to set up a route, a controller, a view, AND a model for our Pages. 14 steps- Introduction 2:03

Our users can view a list of all Pages. They can click a link to view an individual Page. What they CAN'T do right now is create new pages; we had to go into the Rails console to do that. Our next task is to set up a form so that it's easy for our USERS to create Pages, too. 10 stepsRoutes to Update Actions
Now our users can create a new Page. But they'd better get it right the first time, because right now they can't go back and change what they've entered.Maybe we should fix that. Let's give them a form to allow them to update existing Pages. 6 stepsA Route to a Delete Action
For every resource you create, there may come a time when you don't want it any more. So, let's allow our users to delete Pages. 6 steps
