Join Kevin Skoglund for an in-depth discussion in this video Challenge: Pages and sections CRUD, part of Ruby on Rails 4 Essential Training.
…[SOUND].…We're ready for another challenge assignment.…In this challenge, you will use what you've learned in…this chapter to create CRUD actions for our pages and sections.…Here are your objectives for your assignment.…From the command line, generate a PagesController and a…SectionController, with placeholders for the CRUD template you'll need.…Write controller actions for index, show,…new, create, edit, update, delete, and destroy.…Try to write the controller actions without…peaking at SubjectsController unless you get stuck.…
If you copy and paste, you won't learn as much.…However, you can copy and paste the HTML from the…subjects templates that you'll need for the pages and sections templates.…There is no reason to write that all from scratch.…You will need to modify the templates to work with the new controllers and actions.…Pages and sections are going to have different attributes than subjects.…So go to your database schema to review those attributes, and regardless…of the attribute, use the text field helper for all form fields.…
