Index field Enum

[Alexander Sidorov]

Is there any special about using Enum as index field? My index works well till I end some enum field to IndexResult, add it to Map select statement and Store it. After that I get strange exception (very long exception message with index definition string). What am I doing wrong?

It should work.

Without knowing the actual details of the error, we can't help your further.

Please look at the following failing test:

    public class Tests

    {

        [Test]

        public void QueryById()

        {

            var documentStore = new DocumentStore() { Url = "http://localhost:8081", Conventions = { DefaultQueryingConsistency = ConsistencyOptions.QueryYourWrites } };

            documentStore.Initialize();

            IndexCreation.CreateIndexes(typeof(SomeDocumentIndex).Assembly, documentStore);

        }

    }

    public class SomeDocument

    {

        public string Id { get; set; }

        public string Text { get; set; }

    }

    public enum SomeEnum

    {

        Value1 = 1,

        Value2 = 2

    }

    public class SomeDocumentIndex : AbstractIndexCreationTask<SomeDocument, SomeDocumentIndex.IndexResult>

    {

        public class IndexResult

        {

            public string Id { get; set; }

            public SomeEnum SomeEnum { get; set; }

        }

           

        public SomeDocumentIndex()

        {

            Map = docs => from doc in docs

                                      select new { Id = doc.Id, SomeEnum = SomeEnum.Value1 };

            Store(x => x.SomeEnum, FieldStorage.Yes);

        }

    }

The problem is that SomeEnum doesn't exists on the server.

Use a string instead. At any rate, this will be the behavior of the next build.

[Alexander Sidorov]

What do you mean by "use string instead"? Could you please provide an example?
