Ruby: ElasticSearch + Tire error Tire::Search::SearchRequestFailed - IndexMissingException?

Question

I want to use ElasticSearch + Tire to search stored in MongoDB.

However, I'm getting the following error when I try to perform a search:

Tire::Search::SearchRequestFailed in SearchController#index

404 : {"error":"IndexMissingException[[events] missing]","status":404}

From what I understand, this tells me that the indexes are missing for the Event, even though I've told it to generate them when I ran db:setup.

Model:

class Event
  include Mongoid::Document
  include Mongoid::Timestamps 

  include Tire::Model::Search
  include Tire::Model::Callbacks

  field :name, :type => String
  field :description, :type => String
  field :started_at => Time
  field :ended_at => Time

  def to_indexed_json
    self.as_json
  end
end

Controller:

  def search
    Event.tire.search(params[:q])
  end

Any ideas on how to resolve this please?

Set an Initializer ( the following will work locally on your machine and on heroku with bonsai add-on too, just in case ... ):

# config/initializers/bonsai.rb

if ENV['BONSAI_INDEX_URL']
  Tire.configure do
    url "http://index.bonsai.io"
  end
  BONSAI_INDEX_NAME = ENV['BONSAI_INDEX_URL'][/[^\/]+$/]
else
  app_name = Rails.application.class.parent_name.underscore.dasherize
  BONSAI_INDEX_NAME = "#{app_name}-#{Rails.env}"
end

In your model add the index_name :

class Event
  include Mongoid::Document
  include Mongoid::Timestamps 

  include Tire::Model::Search
  include Tire::Model::Callbacks

  index_name BONSAI_INDEX_NAME

  field :name, :type => String
  field :description, :type => String
  field :started_at => Time
  field :ended_at => Time

  def to_indexed_json
    self.as_json
  end
end

Then open your Rails console with rails c and run :

1.9.2p290 :001 >Event.create_elasticsearch_index
 => 200 : {"ok":true,"acknowledged":true} 
1.9.2p290 :002 > Tire.index BONSAI_INDEX_NAME
1.9.2p290 :003 >        import Event.all
1.9.2p290 :004?>   refresh
1.9.2p290 :005?> end

You should see something similar :

MONGODB (0ms) ... ['system.namespaces'].find({})
MONGODB (0ms) ... ['events'].find({})
 => #<Tire::Index:0xca8fb18 @name="your-app-name-development",@response=200 : {"ok":true,"_shards":{"total":10,"successful":5,"failed":0}}> 
1.9.2p290 :006 > 

Now start rails and re-try.
