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) }
