Modifying NEST JsonSerializer settings does not seem to work

[crunchie84]

Hello,

I am using NEST NuGet package v 0.12.0.0 to connect to my ElasticSearch. I want my Enum values to be send to ElasticSearch as their ToString() instead of their index/int value.

I have tried the following:

  var settings = new ConnectionSettings(elasticSearchUri)
    .SetDefaultIndex("my-index")
    .SetJsonSerializerSettingsModifier(m =>
    {
      if (m.Converters == null)
        m.Converters = new List<JsonConverter>(); //required because of nullrefs?
      m.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
    });

But it looks like it keeps sending the Enum values as ints.

I have also tried to modify the serialiserSettings after constructing the ConnectionSettings like so:

  connectionSettings.ModifyJsonSerializerSettings(new JsonSerializerSettings
  {
    Converters = new[] {new Newtonsoft.Json.Converters.StringEnumConverter()}
  });

but both seem to be ignored. Am i missing something here? Could you please provide some more details how to modify the JsonSerializerSettings?

Try this:

settings.AddContractJsonConverters(t => typeof (Enum).IsAssignableFrom(t) ? new StringEnumConverter() : null);

Hey @Mpdreamz i'm trying to upgrade nest-1.0.0-beta1 to 1.0.2 but it seems my contractjsonconverters no longer work. Any clue? I made a minimal testcase which fails: https://gist.github.com/crunchie84/4df1bcdb3071a0b575b7

This was a bug isolated in the TermFilter converter that did a WriteValue on the object instead of preferring to do serialization of the object value.

This should be fixed now!
