Dry::ElasticModel

Add this line to your application's Gemfile:

gem 'dry-elastic_model'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dry-elastic_model

1. Bump VERSION and push a commit to master
2. $ gem build dry-elastic_model.gemspec
3. $ gem push dry-elastic_model-${VERSION}.gem

This gem was created to provide a thin layer between Elasticsearch models mapping and Ruby objects. Right now, if you want to build your own Elasticsearch wrapper, you're on your own when it comes to creating document mappings and mapping ES documents to Ruby code, which can be painful especially if you want to also validate them before pushing.

Responsibilities of this library:

• models that represent Elasticsearch documents
• converting and validating Ruby objects to Elasticsearch documents
• converting & validating Elasticsearch documents to Ruby objects
• providing mapping out-of-box based on created models

Sample model:

  class FooBar < Dry::ElasticModel::Base
    field :text_field, :text
    field :newly_added_text_field, :text, allow_missing: true
    field :keyword_field, :keyword, index: false
    field :date_field, :date
    field :long_field, :long
    field :double_field, :double
    field :boolean_field, :boolean
    field :ip_field, :ip
    list  :list_text_field, :text
    range :range_long_field, :long
  end

This corresponds to following Elasticsearch mapping (calling Foo.mapping.to_json):

{
  "foobar": {
    "properties": {
      "text_field": {
        "type": "text",
        "index": "not_analyzed"
      },
      "newly_added_text_field": {
        "type": "text",
        "index": "not_analyzed"
      },
      "keyword_field": {
        "type": "keyword",
        "index": false
      },
      "date_field": {
        "type": "date",
        "format": "strict_date_optional_time||epoch_millis"
      },
      "long_field": {
        "type": "long"
      },
      "double_field": {
        "type": "double"
      },
      "boolean_field": {
        "type": "boolean"
      },
      "ip_field": {
        "type": "ip"
      },
      "list_text_field": {
        "type": "text"
      },
      "range_long_field": {
        "type": "long_range"
      }
    }
  }
}
