multiple form submit buttons for a single form rails 4 -


i'm attempting have form allows me either delete multiple posts based on checked or action. i'm struggling accessing post ids form. if use f.submit tags code works fine. however, when try use bootstrap buttons not work.

below view, has form located inside of bootstrap table , submit buttons on outside of table.

         <%= form_for :pending_forms, html: {method: 'get'} |f| %>              <table class="table">                 <tbody>                     <% if @pending_posts.any? %>                             <% @pending_posts.each |post| %>                                 <tr>                                     <td><%= post.post_name %></td>                                     <td><%= post.created_at %></td>                                     <td><%= check_box_tag 'post_ids[]', post.id %></td>                                 </tr>                             <% end %>                     <% end %>                 </tbody>             </table>             <button type="submit" class="btn btn-danger">remove post</button>             <button type="submit" class="btn btn-primary">go live</button>           <% end %> 

 if params[:commit] == "remove post"    pendingpost.where(id: params[:post_ids]).destroy_all  end  if params[:commit] == "go live"    #do stuff  end

it best write submit buttons inside form_tag scope. 

<%= form_tag %>   <table>     <tbody>        <% if @pending_posts.any? %>           <% @pending_posts.each |post| %>             <tr>                <td><%= post.post_name %></td>                <td><%= post.created_at %></td>                <td><%= check_box_tag 'post_ids[]', post.id %></td>             </tr>           <% end %>        <% end %>     </tbody>   </table>   <button type="submit" class="btn btn-danger">remove post</button>   <button type="submit" class="btn btn-primary">go live</button>   <% end %>
