ruby on rails - Exclude current object from has_many belongs_to query -

a shoe has_many socks. socks belong shoes.

using socks controller want make comparison siblings same parent_id shoe.

sockscontroller   def show     @sock = sock.find(params[:id])     @shoe = shoe.find(@sock.shoe_id)     @socks = @shoe.socks   end 

socks - show.html.erb

  <% @socks.each |sock| %>     <%= link_to sock.sock_name %>   <% end %> 

naturally i'm getting socks in show.html.erb, want exclude current sock @socks = @shoe.socks. there way this? i'm exploring where.not options now, have never tried before.

additionally there inherently wrong initial def show? think it's ok, feel i'm being redundant in calls, , might able simplify reduce queries.

if want exclude current sock in view, this.

    <% @socks.each |sock| %>       <% next if sock.id == @sock.id %>       <%= link_to sock.sock_name %>     <% end %>
