Active scaffold plugin for searching with Sunspot Solr

Install

rails plugin install git://github.com/cristiansorinel/active_scaffold_sunspot_search.git

Usage

Supposing you have a sunspot-enabled model like:

class Comment < ActiveRecord::Base
  searchable do
    text :name
    integer :post_id
  end
end

To use it, in your controller swap the default active scaffold search action with solr_search action like this:

active_scaffold :comment do |conf|
  conf.actions.exclude :search
  conf.actions.add :sunspot_search
end

Advanced

To customize the search behavior override the conditions_for_solr_search in your controller

def conditions_for_solr_search(solr, query)
  solr.all_of do
    solr.keywords(query) unless query.blank?
    if not project.owner_id == current_user.id
      solr.with(:project_role_ids).any_of(current_user.project_role_ids)
    end
    solr.with(:project_id).equal_to(project.id)
    solr.order_by(:created_at, :desc)
  end
end

Note

Solr paginates your result (Sunspot sets a default of 30 results per page). We should not try to paginate again using the database. I had the AS find_page function overridden (bad) to use data from Solr for pagination because it's pretty coupled and has no extension API. So either we refactor find_page to expose an extension API, either (currently) we have to stay in sync with upstream by migrating any changes.
