Tanning Bed is a generic Solr interface for models, because models are too sexy to get the their tans from the sun directly ;-)

DESCRIPTION:

Tanning Bed is Solr for models. Tanning Bed provides a Ruby interface for the Solr (lucene.apache.org/solr/) search engine to use in you're models not matter whether they are Datamapper, Active Record, Couchrest or just general Ruby classes.

FEATURES/PROBLEMS:

  • Incredibly simple in design, no fancy hooks

  • Very Ruby

SYNOPSIS:

Setup

Using TanningBed for a given class involves including the TanningBed model and then implementing a few (easy) methods.

Objects must implement:

* id - unique identifier for the record
* Class.get - this method receives and object's id and loads it
* solr_keys - an array of method names, the method results will be added to the index

Examples

CouchRest
id is already implemented and so is get.  CouchRest has a method called keys which we'll use

  class MyDocument < CouchRest::Model
    include TanningBed

    key_accessor :name
    key_accessor :address

    def solr_keys
      keys
    end
ActiveRecord
id is implemented in ActiveRecord already

 class MyModel < ActiveRecord::Base
   include TanningBed

   def get(value)
     find(value)
   end

   def solr_keys
     attribute_names
   end
 end

Adding, Updating or Deleting

Adding a record is accomplished by

Changing Solr connection

To change the url for Solr or to change whether autocommit is on or not add the following to you're instantiation (for example config/enviroments/production.rb) 

 TanningBed.solr_connection(YOUR_SOLR_URL, :off)

Handling connection issues

Only you can decide the best way to handle Solr exceptions in your application.  TanningBed provides a simple hook to allow you to do just that.  By default connection exceptions (Errno::ECONNREFUSED) in TanningBed methods simply output to STDERR.  This isn't really sufficient unless you're watching STDERR on you're application for problems.  A common thing to want to do is simply be notified of the error while failing silently.  To do that you might setup something like this: 

 TanningBed.on_solr_exception = Proc.new {|e| deliver_solr_down_email(e) }

REQUIREMENTS:

  • Solr (bundled)

  • Solr-Ruby library (bundled)
