Vapor - How to access the FluentValue type? - vapor

Question

This is a Swift, Vapor related question.
How do I access the FluentValue type when trying to create a ResponseRepresentable Class?
The Vapor Model Protocol demands an ID; I want to assign my ID variable as a FluentValue optional. However, I can't find it (even after Import Vapor & Import Fluent).
import Vapor
import VaporMySQL
let drop = Droplet()
drop.post(String.self, "boughtcoffee") { request, buyerName in
let coffeeledger = CoffeeLedger(name: buyerName, time: 0)
guard let atLeastOneDrinker = request.data["drinker"].string else {
throw Abort.custom(status: .badRequest, message: "Please enter some drinkers")
}
return coffeeledger
}
import Vapor
import Fluent
final class CoffeeLedger: Model {
var id: FluentValue?
var name: String
var time: Int
init (name: String, time: Int){
self.name = name
self.time = time
}
}
I am following the Vapor video on setting up a Model that is Response Representable. https://www.youtube.com/watch?v=E1ir7_s_VTw

Answer 1

FluentValue became Node in Vapor 0.15. (Current version of Vapor at this time is 0.16).
Additionally, the init and serialize methods became init(node: ...) and makeNode().
The code on the model page (https://vapor.github.io/documentation/fluent/model.html) should be up to date and working with Vapor 0.15 and later.
If there is a specific error you are getting, create another question here with that error message and I can try to help!

Answer 2

Great. That works beautifully. The following is based on your documentation. Hopefully it helps others who are using Vapor:
import Vapor
import Fluent
final class CoffeeLedger: Model {
var id: Node?
var buyername: String
var drinkername: String
var time: Int
init(buyername: String, drinkername: String, time: Int) {
self.buyername = buyername
self.drinkername = drinkername
self.time = time
}
init(node: Node, in context: Context) throws {
id = try node.extract("id")
buyername = try node.extract("buyername")
drinkername = try node.extract("drinkername")
time = try node.extract("time")
}
func makeNode() throws -> Node {
return try Node(node: [
"id": id,
"buyername": buyername,
"drinkername": drinkername,
"time": time
])
}
static func prepare(_ database: Database) throws {
try database.create("Ledger") { users in
users.id()
users.string("buyername")
users.string("drinkername")
users.int("time")
}
}
static func revert(_ database: Database) throws {
try database.delete("Ledger")
}
}
