Localitzation and Validation Messages

[ivansoriabia]

Hello Harry!

I'm finishing my project with FormFactory and I'm trying to validate the data from my inputs. In ASP .NET Core you can set it like this:

public class SomeViewModel
{
    [Required(ErrorMessage = "Your elegant error message goes here")]
    public int ProductId { get; set; }
} 

But I haven't found any way to set it when I create my PropertyVms, so there is way to set my custom error message?

Another thing that I would like to change is the language that the NotOptional / Optional Label is shown. I would like to set it in Spanish.

Thank You!

So you are creating PropertyVms programatically? You can add your own attributes: e.g.

new PropertyVm(typeof(DateTime), "StartDate")
{
    DisplayName = "Start Date",
    Value = startDate
    GetCustomAttributes = () => new object[] {new DisplayFormatAttribute {DataFormatString = "dd/MM/yyyy"}]
},

So you can add a RequiredAttribute into the GetCustomAttributes Func

I think to fix the optional message you'll have to either

1. take your own custom version of /Views/Shared/FormFactory/Form.Property.cshtml and modify it to have a hardcoded version

2, or take a fork, and modify mine to work of a resx file, and send me a Pull Request

This PR already added a resx file

What I need to do to add Spanish translation to FormFactory?

Being a Brit, I'm terrible at i18n, but have a read of this.

As I recall

1. add keys to the resx files for the text you want translated see Resources.resx and Resources.es.resx - VS should give you a custom editor for doing this.

2. use the resource in the code e.g. CompareAttribute.cs

3. get your app to set the correct CurrentCulture

Does creating a new resource file (e.g. Resource.fr.resx) in our projects work? or do we have to clone FormFactory and create the new language resource files in it for it to work?

[mcintyre321]

I'm not sure, I'm not a big resx user.
