Question

我试图在我的一个控制器（LeagueController）中添加一个“创建”，所以我创建了一个Create视图，该视图使用了我的League对象。

但是，当我提交表单时，它并没有按我希望的那样重定向回Index视图，也没有输入日志条目来说明我创建了一个联赛。

League类

public class League : BaseEntity
{
    [Required]
    [DataType(DataType.Text)]
    public string LeagueName { get; set; }

    [Required]
    [DataType(DataType.Text)]
    public string LeagueInitials { get; set; }

    [DataType(DataType.Text)]
    public string LeagueURL { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime Founded { get; set; }

    [InverseProperty("League")]
    public ICollection<Team> Teams { get; set; }

    [ForeignKey("LeagueID")]
    public ICollection<LeagueOwners> LeagueOwners { get; set; }
}

LeaguesController类

public class LeaguesController : Controller
{
    private MyDBContext context;
    private ILogger logger;

    public LeaguesController(MyDBContext context, ILogger logger)
    {
        this.context = context;
        this.logger = logger;
    }

    public IActionResult Index()
    {
        this.logger.LogInformation("Reached League Index");
        return View();
    }

    [Route("Create")]
    public IActionResult Create()
    {
        this.logger.LogInformation("Creating a league");
        return View();
    }

    [HttpPost]
    public IActionResult Create(League league)
    {
        this.logger.LogInformation("Create button clicked!");
        return this.RedirectToAction("Index");
    }
}

Create.cshtml

@model MySite.Core.Entities.League

@{
    ViewData["Title"] = "Create";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Create</h2>

<h4>League</h4>

        </form>

<div>

</div>

Answer 1

在您的表单Last word : sentence Remaining words : This is a中添加标记以指向正确的控制器<form asp-action="Create" method="post">

不要强制执行路线，这只是反模式。

Answer 2

第一种方法是，您可以删除get方法上的[Route("Create")]。

第二种方法是您可以将[Route]属性添加到post方法中，如下所示：

[Route("Create")]
public IActionResult Create()
{
    this.logger.LogInformation("Creating a league");
    return View();
}
[Route("Create")]
[HttpPost]
public IActionResult Create(League league)
{
    this.logger.LogInformation("Create button clicked!");
    return this.RedirectToAction("Index");
}

表单未提交点击
