[英]How to remove property of model from client side validation?
在我的模型中,我有一個User
類,其中變量Password
是必需的屬性。
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
視圖:
@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>
}
在視圖中,我在用戶編輯中排除了“密碼”字段,並且為了在控制器中驗證模型,我使用了[Bind(Exclude="Password")]
,但是它不起作用,因此我使用了ModelState.Remove("Password");
但它在服務器端進行驗證。 如果我使用所有字段(包括Password
),它將在客戶端進行驗證。 如何在客戶端(排除一個字段時)進行驗證?
我假設您的模型是數據庫中的模型。 有時,數據模型不適用於視圖。 為了使其正常工作,我建議您引入解決所有視圖方面的不同ViewModel類。 最有可能的是您的用戶模型,但沒有密碼字段:
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“數據”模型,而是使用視圖模型,然后將其在控制器中映射到數據模型。
