who knows ransack?

I'm using ransack for my searches. I need to search through date fields but only for year. For example I need all documents created in 2011. For those that use ransack, there such a way to do this?

I have used ransack, but what you are looking for is not directly implemented.

You have two options: 1) Use a database specific syntax such as EXTRACT 2) Create a predicate (see github readme) which will which that the date is greater then or eq to 1/1/2011 00:00:00 and less then 1/1/2012 00:00:00

You can see the built-in predicates here: https://github.com/ernie/ransack/blob/master/lib/ransack/constants.rb

I have a form like this:

= simple_form_for @q, :url => unsafe_buildings_path, :html => {:method => :get} do |f|   .block     .column.span-11       .inputs         = f.label :practice_number_eq, t('practice_number')         = f.input :practice_number_eq, :label => false, :required => false         = f.label :property_cont, t('property')         = f.input :property_cont, :label => false, :required => false         = f.label :practice_date_in, t('practice_date')         = f.input :practice_date_in, :as => :date, :label => false, :required => false,                   :start_year => Settings.unsafe_buildings_start_year, :include_blank => true         = f.button :submit, "Cerca"

I want to search also for practice_date where based on year. I'm using postgres as db. How can I integrate "extract" in this form?
