Hands-On Server-Side Web Development with Swift

Implementing the create operation

To create a new item for an instance of your model in the database, call the .save(on:) method:

func newEntry(_ req: Request) throws -> Future<Response> {    return try req.content.decode(JournalEntry.self).flatMap { entry in        return entry.save(on: req)    }.transform(to: req.redirect(to: self.mainPage))}

When the save() method completes, Fluent will automatically have filled in its id with a new, unique value, and it's safe to return.

In order for Fluent to work properly, you're required to remove the default ID in new.leaf:

<input name="id" type="hidden" value="-1" />

Now, let's proceed to implementing the Read operation.
