How will it handle the localization of model Validations about my.extensions.localization.json

[Sandeep321]

Got it working after trying out a couple of approaches. I got it working it using just couple of lines as
services.AddMvc() .AddDataAnnotationsLocalization(o => { var factory = services.BuildServiceProvider().GetService<IStringLocalizerFactory>(); var localizer = factory.Create(typeof(Resource)); o.DataAnnotationLocalizerProvider = (t, f) => localizer; }) .SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

Where Resource is your Resource Class name which matches with the json file name.

Now my model looks like:
`
public class LocalizationModel
{
[Required(ErrorMessage = "The {0} field is required.")]
[MaxLength(4, ErrorMessage = "The field {0} must be a string or array type with a maximum length of '{1}'.")]
public string Name { get; set; }

    [Range(0, 10, ErrorMessage = "The field {0} must be between {1} and {2}.")]
    public int Id { get; set; } 
}

`

My Resource.en.json file looks like:
{ "The {0} field is required.": "The {0} field is required.", "The field {0} must be a string or array type with a maximum length of '{1}'.": "The field {0} must be a string or array type with a maximum length of '{1}'.", "The field {0} must be between {1} and {2}.": "The field {0} must be between {1} and {2}." }

You can use some more readable keys in json file and then do rest of the changes as required

Thanks .. I appreciated!!

@hishamco I have created one example with localization working with DataAnnotations also.
https://github.com/Sandeep321/asp.netcore-JsonResourceLocalizer
might be helpful

[hishamco]

Before I dig into, please check the LocalizationSample.Web, because my JsonLocalizer should work as same as StringLocalizer except it looks for the resources from the JSON files

I tried some ways as I found over StackOverflow etc but nothing seems right for this Json localizer

Can you point to some of those?

[hishamco]

Hope you share your repo if it's public, so I can create a link for it

[Sandeep321]

I will create one and share soon. and provide the link here.

As I see the DataAnnotations issue that you talked about before isn't related directly to the JsonLocalizer perhaps a setup issue, furthermore I expect that you 'll reference my package that's published in NuGet rather than copy paste the code again without adding a value 😄

Thank you @Sandeep321 for sharing.
This addresses an issue we had with DataAnnotation, and confirmed a solution we expected to work.

I wonder @hishamco though if it's possible to add this setup it into the library.
For example, using extension method to MVC, e.g. AddJSONDataAnnotationsLocalization() maybe?

[hishamco]

@abarrak the DataAnnotation stuff is handled in the MVC. I will open a new issue with your suggestion and investigate on that
