In this episode, we're building out the UI for editing a book, including restricting access so only the book owner can see or edit the page. We start by writing feature tests: first, verifying unauthenticated users get redirected, and then checking that the edit form actually shows the book details (title, author, and status) pre-filled for the user.
We hook up the route and controller for the edit page, make sure authentication middleware is in place, and then create the corresponding Blade view for editing books. Along the way, we make sure that the form fields are correctly pre-populated with the current book info (including handling validation so old input stays if there's an error), and that the current status is selected in the dropdown.
A tricky bit comes up with handling the pivot data (like the user's reading status for a book), so we have to fetch the book through the user's relationship to get that info. We also add a test and logic to ensure users can't edit books they don't own—returning a 403 forbidden status in this case. At the end, all necessary tests are passing, and we're set up to refactor (maybe with a policy) in the future with confidence!
Expect lots of test-driven development here, and some hands-on coding to get the edit experience working smoothly and securely.
