Having trouble with Couchbase view filtering

Question

I'm using spring-data-couchbase, and I'm trying to create a backing view for a findAll() query. I've created a document named ClusterCodeXref, and a view named allClusterCodeXrefs matching my model class. I need to filter the based on the calling class (did I state that right?), because this bucket will be used for other applications too.

My model looks like this:

package com.company.aad.xref.model;

@Document
public class ClusterCodeXref implements Serializable {

    private static final long serialVersionUID = 3072475211055736282L;

    @Id
    String id;

    @Field("SET_NUM")
    String setNum;

    ...
}

This is the repository class:

@Repository

public interface ClusterCodeXrefRepository
  extends CrudRepository<ClusterCodeXref, String> {

    @View
    List<ClusterCodeXref> findAllClusterCodeXrefs();
}

And this is my view:

function (doc, meta) {  
  if (doc._class == "com.company.aad.xref.model.ClusterCodeXref") {
    emit(meta.id, null);
  }
}

But when I run the findAllClusterCodeXrefs() query, no rows are returned. If I take the if-statement out, I get everything I expect. What am I doing wrong?

Answer 1

Apparently the _class field isn't automatically added to imported data. I need to add _class to my dataset (which I imported from a CSV file) manually.
