Learn to implement a basic “new” action by writing controller code and the related HTML for the view template. The new action is a Read operation which displays an HTML form for preparing to edit a database record.
- [Voiceover] Now that we understand…the basics of forms, we're ready to implement…the Create Actions in our controller.…The create part of CRUD is made up of two standard actions,…New and Create, and they work together.…The New action displays a web form…that we can fill out and submit to the Create action.…Create action handles the form processing.…Let's focus on the New action in this movie.…Let's begin by adding a link from the Index template…to our New action.…You can see, I already have the link here…for Add New Subject.…Let's go and actually add the code that we need…to make that work.…
