rails 3.2 ice_cube and recurring_select - ruby-on-rails

Question

I'm trying to save a recurring_select to a serialized attribute to handle recurring events on a rails app.
Using Jayson's post I manage to get the schedule saved but now I can't get the saved
attribute shown in index view or update the recurring_select in _form view
This is my model
class Todo < ActiveRecord::Base
attr_accessible :item, :completed, :schedule, :start_date
after_initialize :default_values
validates :item, presence: true
belongs_to :list
belongs_to :tasklib,
:foreign_key=>"item"
#recuring model
include ActiveModel::Validations
include ActiveModel::Conversion
extend ActiveModel::Naming
attr_accessor :schedule
serialize :schedule, Hash
def schedule=(new_schedule)
write_attribute(:schedule,RecurringSelect.dirty_hash_to_rule(new_schedule).to_hash)
end
def converted_schedule
the_schedule = Schedule.new(self.start_date)
the_schedule.add_recurrence_rule(RecurringSelect.dirty_hash_to_rule(self.schedule))
the_schedule
end
end
This is my index view :
h1><%= #list.name %></h1>
<table class="table table-striped">
<thead>
<tr>
<th><%= model_class.human_attribute_name(:item) %></th>
<th><%= model_class.human_attribute_name(:start_date) %></th>
<th><%= model_class.human_attribute_name(:schedule) %></th>
<th><%=t '.actions', :default => t("helpers.actions") %></th>
</tr>
</thead>
<tbody>
<% #list.todos.each do |todo| %>
<tr>
<td><%= todo.item %></td>
<td><%= todo.start_date %></td>
<td><%= todo.schedule %></td>
<td>
<%= link_to t('.edit', :default => t("helpers.links.edit")),
edit_list_todo_path(#list, todo), :class => 'btn btn-mini' %>
<%= link_to t('.destroy', :default => t("helpers.links.destroy")),
list_todo_path(#list, todo),
:method => :delete,
:confirm => t('.confirm', :default => t("helpers.links.confirm", :default => 'Are you sure?')),
:class => 'btn btn-mini btn-danger' %>
</td>
</tr>
<% end %>
</tbody>
</table>
and this is my _form view:
<%= simple_form_for [#list, if #todo.nil? then #list.todos.build else #todo end], :html => { :class => 'form-horizontal' } do |f| %>
<%-# f.input :item, input_html: {class: "span6", rows: 3} -%>
<%= f.collection_select :item, Tasklib.order(:name),:name,:name, include_blank: true %>
<%= f.label :start_date, "date" %>
<%= f.input :start_date %>
<%= f.label :schedule %>
<%= f.select_recurring :schedule, nil, :allow_blank => true %>
<div class="form-actions">
<%= f.submit 'Save', :class => 'btn btn-primary' %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
lists_path, :class => 'btn' %>
</div>
<% end %>

OK I found it !
The model should be :
def schedule=(new_schedule)
if new_schedule == nil
new_schedule = IceCube::Schedule.new( self.start_date )
end
write_attribute(:schedule, RecurringSelect.dirty_hash_to_rule(new_schedule).to_hash)
end
def converted_schedule
if !self.read_attribute(:schedule).empty?
the_schedule = IceCube::Schedule.new( self.start_date )
the_rule = RecurringSelect.dirty_hash_to_rule( self.read_attribute(:schedule) )
if RecurringSelect.is_valid_rule?(the_rule)
the_schedule.add_recurrence_rule( the_rule)
end
the_schedule
end
end
and the form view should only set a new recurring select like:
<%= f.select_recurring :schedule, [ ["No recurring", "{}"] ], :allow_blank => true %>
