I have build a contacts page which displays a number of contacts. I have attached a check_box_tag with each row of these. And then a button to delete those selected. But it is not working. Following is the code snipet, _contact.html.erb> <% @contacts.each do |contact| %> > <tr class=''contactrow'' id=''contact-<%=contact.id%>''> > <td ><%= check_box_tag "contact_ids[]", contact.id %> </td> > <td><%= contact.name %></td> > <td><%= contact.phone %></td> > <td><%= contact.mailid %></td> > <td><%= contact.age %></td> > <td><%= link_to ''Show'', > contact, > :remote=>true > %></td> > <td><%= link_to ''Edit'', > edit_contact_path(contact), > :remote => true%></td> > <td><%= link_to ''Destroy'', > contact, > :method => :delete, > :data => { :confirm => ''Are you sure?'' }, > :remote => true %></td> > <td><%= link_to ''Send Mail'', > {:action => "createmail", :id => contact.id}, > :remote => true %></td> > </tr> > <% end %>> <%= link_to ''Destroy Selected'',{:action => ''destroySelected'',>:id => ''contact_ids''},>:remote => true%>>In Contacts_controller def destroySelected> Contact.delete_all(:id => params[:contact_ids]) > respond_to do |format| > format.html {redirect_to contacts_url} > format.js > end > end >but my development log says no value has been recieved in "id".
