Woops in all my changes I put name instead of firstname on my coordinators.. This is now correct but the original issue is still there.. which is when I try and call state.county.name or coordinator.state.name or county.state.name.
I am quite sure that county.name exists and that state.name exists. I ran some commands in the console, here is what I get: examplestate = State.find(1) => #<State id: 1, name: "Alabama", abreviation: "AL", created_at: "2011-04-04 16:32:08", updated_at: "2011-04-04 16:32:08"> examplestate.name => "Alabama" examplecounties = examplestate.counties => [#<County id: 3, name: "Baldwin County", state_id: 1, created_at: "2011-04-04 16:32:32", updated_at: "2011-04-04 16:32:32">, #<County id: 4, name: "Cherokee County", state_id: 1, created_at: "2011-04-04 16:32:32", updated_at: "2011-04-04 16:32:32">, #<County id: 5, name: "Chilton County", state_id: 1, created_at: "2011-04-04 16:32:33", updated_at: "2011-04-04 16:32:33">, #<County id: 6, name: "Clarke County", state_id: 1, created_at: "2011-04-04 16:32:33", updated_at: "2011-04-04 16:32:33">, #<County id: 7, name: "Colbert County", state_id: 1, created_at: "2011-04-04 16:32:33", updated_at: "2011-04-04 16:32:33">, #<County id: 8, name: "Crenshaw County", state_id: 1, created_at: "2011-04-04 16:32:33", updated_at: "2011-04-04 16:32:33">, #<County id: 9, name: "Cullman County", state_id: 1, created_at: "2011-04-04 16:32:33", updated_at: "2011-04-04 16:32:33">, #<County id: 10, name: "DeKalb County", state_id: 1, created_at: "2011-04-04 16:32:33", updated_at: "2011-04-04 16:32:33">,etc.. etc.. examplecounties.each do |county| puts county.coordinator.firstname end Jessica Ron P. Dale Gerry Garry Tami Samuel etc. etc. So when I call a coordinators firstname from a county, from a state.. it seems to work.. but then when I try that in the view for instance: My state controller calls @state.all and in the state index view I have: <% @states.each do |state| %> <strong><%= state.name %></strong> <% state.counties.each do |county| %> <p><%= county.coordinator.firstname %> </p> <% end %> <% end %> I get this error: undefined method `firstname' for nil:NilClass On May 26, 3:42 am, Michael Pavling <pavl...@gmail.com> wrote: > On 26 May 2011 07:07, Aaron Mills <aa...@jailbreakcreative.com> wrote: > > > I am getting:this error.
