-

i have seen railscast here

in episode ryan bates show data values. , creates seperate class sending json data browser. have done same. however, instead of elements, add check boxes table well. have tried many different ways same. however, check boxes donto appear in datatable columns. appears "true" or "false"values corresposnd checkboxes.

i posted question on datatables forum did not receive answer useful.

here code class on server side:

class listingsdatatable   delegate :params, :h, :link_to, :number_to_currency, to: :@view    def initialize(view)     @view = view   end    def as_json(options = {})     {       secho: params[:secho].to_i,       itotalrecords: listing.count,       itotaldisplayrecords: listings.total_entries,       aadata: data     }   end  private    def data     listings.map |listing|       [         h(listing.id),         link_to(listing.name, listing),         h(listing.telephone),         h(listing.fax),          #this code tried no checkboxes, instead         # if following included no data shows in table         #check_box_tag('checked?', listing.checked),         #check_box_tag('collected', listing.collected),         #check_box_tag('digitized', listing.digitized),         #check_box_tag('in db?', listing.in_database)          #if include following,           #these boolean values stored in listings table         #which generate "true" or "false" in columns. works show boolean    values. checkboxes dont.            h(listing.keep),         h(listing.checked),         h(listing.collected),         h(listing.digitized),         h(listing.in_database)       ]     end   end    def listings     @listings ||= fetch_listings   end    .........

here index.html.erb file

<h3><%= link_to 'click here create new listing', new_listing_path %></h3>  <table id="listings" class="display" data-source="<%= listings_url(format: "json")%>"> <thead>   <tr>   <th>id</th>   <th>name</th>   <th>telephone</th>    <th>keep listing?</th>   <th>checked</th>   <th>collected?</th>   <th>digitized?</th>   <th>in db?</th>   </tr> </thead>  <tbody>  </tbody> </table>  <br />

here javascript file listings.js

//#jquery  //initialize datatable $(document).ready(function() {   var otable = $('#listings').datatable(   {     "spaginationtype":  "full_numbers",     "bjqueryui": true,     "bsortclasses": false,     "sscrollx": "90%",     "bscrollcollapse": true,     "sdom":  '<"top"iflp<"clear">>rt<"bottom"iflp<"clear">>',     "bprocessing": true,     "bserverside": true,     "sajaxsource": $('#listings').data('source')   }); });

can please me in understanding how can check boxes show in columns

thanks lot.

so couldn't figure way of making work datatables.net. documentation vague. however, realized may design since offer datatables jquery s free option have editable datatable commercial product. since couldn't make work, chose implement own editable table in 4 hours. no longer use datatables
