Auto rebuilding Ferret indexes
A few month ago I wrote a little Rails plugin that automatically rebuilds my Ferret indexes if model field definitions have changed. Because I’m currently busy with finishing the next RSpactor release and my blog is so boring at the moment I decided to publish the plugin today. So lets say ‘hey’ to AAFAutoRebuild.
AAFAutoRebuild comes as a rake task and scans all your models for acts_as_ferret field definitions. It keeps the current state of all models in super secret state file in your home directory. If you change a model (e.g. add a field to your aaf call) and rake the task again AAFAutoRebuild diffs the current state with the latest saved and invokes rebuild_index on that model’s class.
rake ferret:index:auto_rebuild
The main purpose behind AAFAutoRebuild was to reduce deploy time when publishing/updating my rails apps with Capistrano. The following cap task gets invoked everytime I deploy my ferret based apps:
desc "Auto rebuild ferret index" task :rebuild, :roles => [:ferret] do run "cd #{current_path}; rake RAILS_ENV=production ferret:index:auto_rebuild" end
- Git Repo: git://github.com/rubyphunk/aafautorebuild.git
- Plugin’s home: http://github.com/rubyphunk/aafautorebuild/tree
- Have a look at the README file for configuration details.

I am currently using Rails 2.0.2, ferret 0.11.6, and acts_as_ferret 0.4.3. I know that I need a newer version of Rails to make aaf_auto_rebuild work, but is there an older version of aaf_auto_rebuild to work with Rails 2.0.2?
The error message I am getting is as following:
rake ferret:index:auto_rebuild
(irb):1: warning: parenthesize argument(s) for future version
Syntax error: compile error
(irb):1:syntax error, unexpected ':', expecting $end
rake ferret:index:auto_rebuild
Any help will be appreciated. Thanks.

I just realized that aaf_auto_rebuild rebuilds Ferret index if model field definitions have changed, it seems more like a deployment tool. But what I really need is to run a background process to incrementally and periodically update/add index entries into ferret index as data in database are being updated and inserted. Any ideas how to do this? Thank you very much.

You're right. aaf_auto_rebuild is primarily meant for use as a deployment tool.
I'm not exactly sure what you need but if you use the acts_as_ferret plugin your models should automatically update their indexes themselves if any data has changed.

i had to change
File.basename(model_file, ".rb").classify.constantize
to
File.basename(model_file, ".rb").camelize.constantize
as my model names are already singularized. e.g. 'Address'.singularize => 'Addres' / error !
thanx for the plugin / very useful

I had the same exact problem as above and fixed it the same way.
