acts_as_solr Rails plugin
This plugin adds full text search capabilities and many other nifty features from Apache’s Solr to any Rails model. It was based on the first draft by Erik Hatcher.
The current stable release is v0.9 and was released on 06-18-2007.
Please refer to the CHANGE_LOG
For Rails >= 2.1:
script/plugin install git://github.com/mattmatt/acts_as_solr.git
For Rails < 2.1:
cd vendor/plugins git clone git://github.com/mattmatt/acts_as_solr.git rm -rf acts_as_solr/.git
Make sure you copy
vendor/plugins/acts_as_solr/config/solr.yml to your Rails
application’s config directory, when you install via
- Java Runtime Environment(JRE) 1.5 aka 5.0 http://www.java.com/en/download/index.jsp
- If you have libxml-ruby installed, make sure it’s at least version 0.7
Basically everything is configured to work out of the box. You can use
rake solr:start and
to start and stop the Solr web server (an embedded Jetty). If the default JVM options aren’t suitable for
your environment, you can configure them in solr.yml with the option
jvm_options. There is a default
set for the production environment to have some more memory available for the JVM than the defaults, but
feel free to change them to your liking.
# Just include the line below to any of your ActiveRecord models: acts_as_solr # Or if you want, you can specify only the fields that should be indexed: acts_as_solr :fields => [:name, :author] # Then to find instances of your model, just do: Model.find_by_solr(query) #query is a string representing your query # Please see ActsAsSolr::ActsMethods for a complete info
acts_as_solr in your tests
To test code that uses
acts_as_solr you must start a Solr server for the test environment. You can do that with
rake solr:start RAILS_ENV=test
However, if you would like to mock out Solr calls so that a Solr server is not needed (and your tests will run much faster), just add this to your
test_helper.rb or similar:
class ActsAsSolr::Post def self.execute(request) true end end
