区别：[ScaffoldColumn（假）]和[显示器（AutoGenerateField = FALSE）] [英] difference between: [ScaffoldColumn (false)] and [Display (AutoGenerateField = false)]

问题描述

要呈现的HTML编辑我的看法，我使用助手 @ Html.EditorForModel（）。

To render HTML in my edit view, I use the helper @Html.EditorForModel().

我的模型：

[Required(ErrorMessage = "Campo obrigatório")]
[Display(Name = "Nome completo")]
public string Name { get; set; }

[Required(ErrorMessage = "Campo é obrigatório")]
[StringLength(100, ErrorMessage = "A {0} deve ter pelo menos {2} characteres.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Senha")]
public string Password { get; set; }

[DataType(DataType.Password)]
[Display(Name = "Confirmar senha")]
[Compare("Password", ErrorMessage = "A nova senha e a confirmação da senha não conincidem.")]
public string ConfirmPassword { get; set; }

[Required(ErrorMessage = "Campo obrigatório")]
[Display(Name = "Convidado")]
[UIHint("IsGuest")]
public bool IsGuest { get; set; }

[RequiredIf("IsGuest", true, ErrorMessage = "Campo é obrigatório")]
[ScaffoldColumn(false)]
public string CodeGuest { get; set; }

属性： codeGuest 不应该由助手创建的 @ Html.EditorForModel（）。 （我想手动创建它。）

Property: CodeGuest should not be created by the helper @Html.EditorForModel(). (I would like to create it manually.)

在互联网上阅读，我发现了几个点，想知道其中的差别。

Reading on the Internet, I found several points and would like to know the difference.

记住，我不希望它被隐藏呢，这个领域将只通过该创建

Remembering that I do not want it to be hidden, this field will only be created by this

EditorTemplates（IsGuest.cshtml）：

@using BindSolution.AndMarried.Model;
@model BindSolution.AndMarried.Models.RegisterModel
@Html.EditorFor(e => e.IsGuest)
<span>TESTE</span>
@Html.EditorFor(e => e.CodeGuest)

问：

之间有什么区别： [ScaffoldColumn（假）] 和 [显示（AutoGenerateField = FALSE）]

为什么我不能让 [显示（AutoGenerateField = FALSE）有效果：打电话时不生成HTML字段 @ Html.EditorForModel（）`。

Why can not I make [Display (AutoGenerateField = false)] have the effect: 'do not generate the HTML field when [e-mail]()`.

推荐答案

的 EditorForModel（）和 DisplayForModel（） HTML辅助方法，使渲染鉴于目前的模型基础上， ViewData.ModelMetadata 属性决定。默认 DataAnnotationsModelMetadataProvider 设置ModelMetadata的基础上，DataAnnotation属性属性。

The EditorForModel() and DisplayForModel() Html helper methods makes decision of rendering view of the properties of the current Model based on the ViewData.ModelMetadata. The default DataAnnotationsModelMetadataProvider sets the properties of ModelMetadata based on the DataAnnotation attributes.

ScaffoldColumnAttribute.Scaffold 影响 ModelMetadata 的两个属性，即 ShowForDisplay 和 ShowForEdit 。

ScaffoldColumnAttribute.Scaffold affects two properties of ModelMetadata i.e. 'ShowForDisplay' and 'ShowForEdit'.

DisplayAttribute 不影响到 ModelMetadata 上面的两个属性。

DisplayAttribute does not affects the above two properties of ModelMetadata.

这就是为什么这些两个属性不会对产生的Html同样的效果。

That is why these two attributes do not have the same effect on generating Html.
