asp.net的MVC如何通过完整的模型从视图到控制器 [英] asp.net mvc how to pass full model from view to controller

问题描述

我有这样的表视图中的

<table class='sendemailtable'>                
@if (!string.IsNullOrEmpty(Model.CustomerName))
{
<tr>
   <td style="font-size: 26px;">
   @Html.Label(string.Empty, Model.CustomerName)
   </td>
</tr>
}                   

<tr><td style="padding-top: 15px;">To:</td></tr>
<tr>
   <td>
   @Html.TextBoxFor(m => m.EmailTo)
   @Html.ValidationMessageFor(m => m.EmailTo);
   </td>
</tr>

<tr><td style="padding-top: 15px;">Subject:</td></tr>
<tr>
<td style="font-size: 22px;">
@Html.TextBoxFor(m => m.EmailBody)
</td>
</tr>

few more

<button style="..." type="submit">SEND</button>

</table>

这些都不是从模型中的所有项目，它有一些多个ID，不能在UI present，有一定的财产，只有吸气

These are not all items from model, it has some more ids which are not present in ui, have some property with only getter

    public int OfferID;
    public int SomeOfferID;
    public int CustomerID;

    #region Email

    [Required]
    [DataType(DataType.EmailAddress)]
    [RegularExpression(@"[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}", ErrorMessage = "Incorrect email")]
    public string EmailTo;

    private string emailBodyDefault;
    public string EmailBody
    {
        get
        {
            if (string.IsNullOrEmpty(emailBodyDefault))
                emailBodyDefault = string.Format("Hi,{1}please take a look. Offer ID: {0}{1}{1}Thanks", SomeOfferID, Environment.NewLine);

            return emailBodyDefault;
        }

        set { emailBodyDefault = value; }
    }

    private string emailSubject;
    [Required]
    public string EmailSubject
    {
        get
        {
            if (string.IsNullOrEmpty(emailSubject))
                emailSubject = string.Format("Offer ID: {0}", SomeOfferID);

            return emailSubject;
        }

        set { emailSubject = value; }
    }

    #endregion

我想通过我的全模式控制器，以便能够从控制器的动作发送电子邮件。还需要验证用户的电子邮件，以及非空的对象时，用户点击发送。我怎样才能做到这一点？

I want to pass full my model to controller, to be able to send email from controller's action. Also need to validate user's email, and non-empty subject when user clicks send. How can i do this ?

推荐答案

如果你想提交完整的模型，那么你需要在你的表单模型的所有属性。为此，您可以使用 @ Html.HiddenFor（M = GT; m.YourPropertyName）如果你不希望显示他们做。我没有看到你的code任何形式的标签，但我相信有一些？

If you want the complete model to be submitted, then you need to include all the model properties in your form. You can do this using @Html.HiddenFor(m => m.YourPropertyName) if you don't want them to be displayed. I don't see any form tags in your code, but I assume there are some?

您已经验证你的模型属性，你使用了[必填] DataAnnotations，所以要检查这在服务器端，您需要检查ModelState.Valid当您发布的数据控制器。

You already have validation on your model properties as you've used the [Required] DataAnnotations, so to check this on the server side, you need to check ModelState.Valid when you post the data to your controller.

public ActionResult SubmitMyForm(MyModel model)
        {
            if (ModelState.IsValid)
            {
...

回应评论：

形式会是这个样子：

@using (Html.BeginForm())
{
    <table>
    ...
    </table>
}

错误发生，因为使用块里面，你不需要preFIX C＃code与 @ 。请参见这个答案一个解释。

The error is occurring because inside the using block, you don't need to prefix C# code with @. See this answer for an explanation.
