无法将项目添加到数据库

Question

// 这是我在 Paul Hudson 在 youtube 上的教程中提出的问题的延续 -

我尝试将项目添加到数据库（见下图）-

当我点击上图中的 "Add" 按钮时，框应该变为空（见下图）。虽然.Quantum Pizza不会添加到.Statin Island Pizza和.Country pizza的列表中，因为我没有做进一步的编码），但应该如下图 -

但是，结果如下-

现在，我发布代码-----

configure.swift -

import  Fluent
import FluentSQLite
import Vapor
import Leaf // added

public func configure(_ config: inout Config, _ env: inout Environment, _ services: inout Services) throws {
    // Register routes to the router
    let router = EngineRouter.default()
    try routes(router)
    services.register(router, as: Router.self)

    let leafProvider = LeafProvider()    // added
    try services.register(leafProvider)  // added
    config.prefer(LeafRenderer.self, for: ViewRenderer.self)// added

    let directoryConfig = DirectoryConfig.detect()
    services.register(directoryConfig)
    try services.register(FluentSQLiteProvider())
    var databaseConfig = DatabasesConfig()
    let db = try SQLiteDatabase(storage: .file(path:"\(directoryConfig.workDir)pizza.db"))

    databaseConfig.add(database: db, as: .sqlite)
    services.register(databaseConfig)

    var migrationConfig = MigrationConfig()
    migrationConfig.add(model: Pizza.self, database: .sqlite)
    services.register(migrationConfig)
    let serverConfigure = NIOServerConfig.default(hostname: "0.0.0.0", port: 9090)
    services.register(serverConfigure)
}

routes.swift-

import Routing
import Vapor
import FluentSQLite

public func routes(_ router: Router) throws {
    router.get { req -> Future <View> in
        let Newyorker = Pizza(id: 5, name: "Statin Island Pizza", description: "Impractical Jokers Funny Pizza", price: 55)
        let Traditional = Pizza(id: 5, name: "Country Pizza ", description: "Johny Cash Special", price: 55)

        return try req.view().render("welcome",["pizza":[Newyorker,Traditional]])
    }

    router.post(Pizza.self, at: "add") { req, pizza -> Future<Response> in
        return pizza.save(on:req).map(to:Response.self) { Pizza in
            return req.redirect(to: "/")
        }
    }
}

pizza.swift-

import Foundation
import Vapor
import FluentSQLite

struct Pizza: Encodable, Content, Decodable, SQLiteModel, Migration {
    var id:  Int?
    var name: String
    var description: String
    var price: Int
}

leaf screenshot（我试图粘贴代码，但不能，以正确的格式。所以添加屏幕截图）-

编辑 1：单击“添加”按钮后的屏幕截图 -

如果您需要，我很乐意为您提供任何进一步的信息。另外，我想知道我的问题的标题是否应该修改或添加任何内容。谢谢。

Answer 1

您的表单操作应该是 action="add"（您缺少结束操作的结束语）

Answer 2

基于 OxTim 的回答 - 它是。一个简单的 leaf-formatting/inverted-comma 问题。

正确的叶格式 -

 <! DOCTYPE html>
 <html>
  <body>
 <h1> Pizza </h1>
 <p> Welcome to best pizza in the Andromeda Galaxy.
  <ul>
  #for(pizza in pizza) {
  <li> #(pizza.name) </li>
}
 </ul>

 <form method="post" action="/add">
<p>Name: <input type="text" name="name" /></p
<p>Description: <input type="text" name="description" /></p>
 <p>Price: <input type="number" name="price" /></p>
 <button type="submit">Add</button>
 </form>
