绕过客户端验证MVC 3

Question

This is the model which we are using...

Public Class Person
{
        [Display(ResourceType = typeof(BasicTags), Name = "FirstName")]
        [Required(ErrorMessageResourceName = "FirstNameRequired", ErrorMessageResourceType = typeof(BasicErrors))]
        public string FirstName;

        [Display(ResourceType = typeof(BasicTags), Name = "LastName")]
        [Required(ErrorMessageResourceName = "LastNameRequired", ErrorMessageResourceType = typeof(BasicErrors))]
        public string LastName;
}

Both the fields are set as required true. Now we have another developer using this same Model in another view, he doesn`t want this validation for his page, how to skip the validation in the server side and before saving?

The database fields are set as allow null.

ViewData.ModelState.Remove("FirstName") 
ViewData.ModelState.Remove("LastName")

This only removes the client side message but the actual validation still remains. Is there any way, so that I can save.

Thanks.

Answer 1

您应该创建一个具有这些属性但没有针对特定页面的验证注释的自定义视图模型。

Answer 2

Simply don't check ModelState.IsValid on the server side and save your data.

HOWEVER - I would just make a copy of that view model, remove your attributes and be done with it. A ViewModel is for a View - if you have a different view, the standard thing to do is create a new Model. However - its your app - so the solution to do what you wanted is above.

If you are worried about the client side validation, then you have to create your own handler for the submit function and don't check if its valid - just post. Another hack. So - again.. try not to do it this way. : )

You can also call ModelState.Remove("FirstName");

Before ModelState.IsValid and it will do the trick, Like

ModelState.Remove("FirstName");
if(ModelState.IsValid){
     // your code
}
