如何从客户端验证中删除模型的属性?

[英]How to remove property of model from client side validation?

在我的模型中,我有一个User类,其中变量Password是必需的属性。

public class User
{
    public int UserId { get; set; }
    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }
    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }
    [Required]
    [Display(Name="First Name")]
    public string FirstName { get; set; }
    [Required]
    [Display(Name="Last Name")]
    public string LastName { get; set; }
    public string Address { get; set; }
    [Required]
    [EmailValidator(ErrorMessage = "Email entered is not valid")]
    [Display(Name="Email")]
    public string Email { get; set; }
}

我的EditUser视图:

@model User
@using (Html.BeginForm("EditUser", "Users", FormMethod.Post))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)


    <div class="editor-label">
        @Html.LabelFor(model => model.UserName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.UserName)
        @Html.ValidationMessageFor(model => model.UserName)
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.FirstName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.FirstName)
        @Html.ValidationMessageFor(model => model.FirstName)
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.LastName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.LastName)
        @Html.ValidationMessageFor(model => model.LastName)
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.Address)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Address)
        @Html.ValidationMessageFor(model => model.Address)
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.Email)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Email)
        @Html.ValidationMessageFor(model => model.Email)
    </div>
    <p>
        <input type="submit" value="Create User" />
    </p>

}

在视图中,我在用户编辑中排除了“密码”字段,并且为了在控制器中验证模型,我使用了[Bind(Exclude="Password")] ,但是它不起作用,因此我使用了ModelState.Remove("Password"); 但它在服务器端进行验证。 如果我使用所有字段(包括Password ),它将在客户端进行验证。 如何在客户端(排除一个字段时)进行验证?

我假设您的模型是数据库中的模型。 有时,数据模型不适用于视图。 为了使其正常工作,我建议您引入解决所有视图方面的不同ViewModel类。 最有可能的是您的用户模型,但没有密码字段:

public class UserViewModel
{
    public int UserId { get; set; }

    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required]
    [Display(Name="First Name")]
    public string FirstName { get; set; }

    [Required]
    [Display(Name="Last Name")]
    public string LastName { get; set; }

    public string Address { get; set; }

    [Required]
    [EmailValidator(ErrorMessage = "Email entered is not valid")]
    [Display(Name="Email")]
    public string Email { get; set; }
}

因此,不是使用“数据”模型,而是使用视图模型,然后将其在控制器中映射到数据模型。
