Store several text_field strings to array Rails 3 -

i'm trying store strings couple of text_fields have array, , save db. have column named "opening_hours" wich i've tried separate 2 different attributes using virtual attributes this:

model

class venue < activerecord::base     attr_accessible :opening_hours, :start_time, :end_time     attr_writer :start_time, :end_time      def start_time         @start_time.nil? ? @start_time : opening_hours.to_s.split("-").first       end      def end_time         @end_time.nil? ? @end_time : opening_hours.to_s.split("-").last     end end 

the idea type in start_time , end_time this:

view

<%= form_for @venue |v| %>     <p><%= v.label "monday" %><%= v.text_field :start_time %>-<%= v.text_field :end_time %><p/>     <p><%= v.label "tuesday" %><%= v.text_field :start_time %>-<%= v.text_field :end_time %><p/>     <p><%= v.label "wednesday" %><%= v.text_field :start_time %>-<%= v.text_field :end_time %><p/> <% end %> 

the array should in db:

{08-12|09-14|07-13}

with "|" separating different days of week.

i've tried couple of things in controller like:

controller

class venuescontroller < applicationcontroller     def new         @venue = venue.new     end      def create         @venue = venue.new(params[:venue])         @total_time = params[:venue][:start_time]+"-"+params[:venue][:end_time]         @venue.opening_hours = @total_time.map {|t| [t.start_time, t.end_time]}     if @venue.save         redirect_to venue_path(@venue), :notice => "success!"     else         render 'new'     end   end 

but nothing seems work... either saves start_time , end_time last day, or nothing gets saved @ all.

i perhaps may have misunderstood, but...

in create action, there no @venue.save - why not seeing saved.

class venuescontroller < applicationcontroller

def new     @venue = venue.new end  def create     @venue = venue.new(params[:venue])     @total_time = params[:venue][:start_time]+"-"+params[:venue][:end_time]     @venue.opening_hours = @total_time.map {|t| [t.start_time, t.end_time]}     @venue.save end 

end
