如何更改默认的＆QUOT;字段必须是数字＆QUOT; [英] How to change the default "The field must be a number"

问题描述

我工作的一个MVC 3应用程序。一个在模型中的字段的类型是双的和定义如下：

I'm working on an MVC 3 application. One of the fields in the model is of type double and defined as follows:

    [Required(ErrorMessageResourceName = "ListingItemPriceRequired", ErrorMessageResourceType = typeof(ErrorMessages))]
    [Display(Name = "DisplayListingItemPrice", ResourceType = typeof(Display))]
    [Range(1, 500000000, ErrorMessageResourceName = "ListingItemPriceNotWithinRange", ErrorMessageResourceType = typeof(ErrorMessages))]
    public double Price { get; set; }

不过，当我输入一个数字的值与一些尾随空格，如342，我得到默认的消息这个领域的价格必须是一个数字。

Still, when I enter a value of a number with some trailing spaces like "342 ", I get the default message "The field price must be a number".

即使是在价格输入字段验证属性的东西为数据-VAL-号。

Even the validation attribute on the Price input field has something as "data-val-number".

感谢

推荐答案

默认消息被深深烤成的框架，作为一个字符串资源。它是由试图将字符串值double类型绑定时的默认模式添加粘合剂。所以，如果你想改变这种默认的消息，你可以写一个自定义模型粘合剂。下面是我写的有同样的问题，DateTime类型的例子： http://stackoverflow.com/a/7836093/29407

The default message is baked deeply into the framework, as a string resource. It is added by the default model binder when trying to bind the string value to a double type. So if you want to change this default message you could write a custom model binder. Here's an example I wrote for the DateTime type which has the same issue: http://stackoverflow.com/a/7836093/29407
