This function can be extended by block or define subclass of EcoAppsSupport::ComboSearch::SqlHash.
For example, we’d like to search records by created hour. Article.combo_search{:created_at => {:after => 13}} will return records that are created after 13:00.
Send block to combo_search.
Article.combo_search{:created_at => {:after => 13}} do |hash|
hash.match :after, :datetime do |column, value|
"#{Article.convert_tz(column, "%H")} >= #{value}"
end
end
Define subclass of EcoAppsSupport::ComboSearch::SqlHash
class AfterMatch < EcoAppsSupport::ComboSearch::SqlHash match :after, :datetime do |column, value| "#{ActiveRecord::Base.convert_tz(column, "%H")} >= #{value}" end end
