选择不发布信息MVC身份

Question

我已经为我的MVC Web应用程序创建了一个注册页面。当我尝试向用户注册Cuisine_1的信息时，Cuisine_2和Cuisine_3选择框未输入USERCUISINEINFO表中。但是，使用ID创建了一个新的行，并且在网页上显示了一个错误消息，说Cuisine_1，Cuisine_2和Cuisine_3字段需要。

usercuisineinfo

public class UserCuisineInfo

        public int Id { get; set; }
        public string Cuisine_1 { get; set; }
        public string Cuisine_2 { get; set; }

    }

Answer 1

您给所有下拉菜单的名字命名为美食。您需要将它们更改为cuisine_1，cuisine_2和cuisine_3。

Answer 2

您有三个称为 Cuisine的同样命名的下拉列表。更新它们，以便它们反映您的模型上的属性：

 @Html.DropDownList("Cuisine_1", ...
 @Html.DropDownList("Cuisine_2", ...
 @Html.DropDownList("Cuisine_3", ...

当渲染这些控件时，它们将产生一个形式控件，例如：

<select name="Cuisine_1" ....

name属性的值在模型绑定中使用，并且必须对应于viewModel中的属性名称。
