Why doesn't it recognize the Leaf command: #loop

I am starting out with an almost blank project and I can render a simple page from welcome.leaf using this:

router.get("view") { req -> Future<View> in
    let leaf = try req.make(LeafRenderer.self)
    return leaf.render("welcome")
}

However, if I put #loop into welcome.leaf I get this message: 

[ ERROR ] TemplateError.serialize: No tag named `loop` is registered. in /Users/david/CloudStation/XcodeProjects/Vapor3affordat/Resources/Views/welcome.leaf line: 24 column: 1 range: 580..<785 (TemplateSerializer.swift:59)

Why does it not recognize the loop leaf command?

Solution

  • In Leaf 3 #loop() has been renamed to #for. The syntax has also changed. Vapor 2:

    #loop(things, "thing")

    In Vapor 3 this becomes

    #for(thing in things)
