Question

I have a Rails application that in the erb code, I use a select box. What I would like to do is reload the page passing the sort parameter. My controller already handles it, but I don’t know how to reload the page with the selected value from my select box. Here is my code:

<% @options = {:latest => 'lastest' , :alphabetical => 'alphabetical', :pricelow => 'price-low', :pricehigh =>'pricehigh'} %> <%= select_tag 'sort[]', options_for_select(@options), :include_blank => true,:onchange => 'location.reload('location?sort='+this.value)'%> 

Answer 1

Have you considered using an ajax call on your list box? If you have a method on your controller that returns just the sorted list, based on sort parameter, then you could do:

<% @options = {:latest => 'lastest' , :alphabetical => 'alphabetical', :pricelow => 'price-low', :pricehigh =>'pricehigh'} %> <%= select_tag 'sort[]', options_for_select(@options), :include_blank => true,:onchange => remote_function(:url => {:controller => 'your_controller', :action => 'list_sort_method'}, :with => ''sort='+this.value', :update => 'div_containing_list') %>
