Rails ElasticSearch model with fields

Question

I'm using elasticsearch-rails and mongoid I have the following simple mapping with fields:

"title": {
              "type": "string",
              "fields": {
                 "raw": {
                    "type": "string",
                    "index": "not_analyzed"
                 }
              }
           }

My model looks like this:

class ArticlesEvent
include Mongoid::Document
include Elasticsearch::Model

field :title, type: String

attr_accessible :title

def as_indexed_json(options={})
  as_json(except: [:id, :_id])
end

Can anyone show an example how to define the rails model with the title.raw field, and how to access that field? Since the multi fields have been deprecated it's hard to find a working example with rails and mongoid.

Thanks

Note that multi fields are not deprecated, they are well and alive. What was deprecated in version 1.0 was the multi-field type, which can now simply be a string type with an embedded fields structure, i.e. exactly what you have above. — Val

You should be able to achieve this with the following attribute definition in your model:

attribute :title, String, mapping: { 
    fields: {
       raw:  { type: 'string', index: 'not_analyzed' }
    } 
}

I'm using Mongoid, and this code throws an exception: "undefined method `attribute' for ArticlesEvent:Class"

Looks like this is still an open issue with elasticsearch-rails: https://github.com/elastic/elasticsearch-rails/issues/79

You can define below mapping in your model

indexes :name_of_field,type: :keyword, fields: {
    raw: {
      type: :text
    }
  }
