Problem accessing a field 2 tables away in an rhtml file
I am having a problem displaying the 3rd level field teamname in a rhtml file, while I can display the 2nd level fields panic_code and panic_name. The code snippet is ... <% for scenario in @scenarios %> <tr> <td><% unless scenario.panicname_id == nil -%> <%=h scenario.panicname.panic_code %> <%=h scenario.panicname.panic_name %> <% end -%> </td> <td><% unless scenario.note == nil -%> <% unless scenario.note.team_id == 1 -%> <%=h scenario.note.team.teamname %> <% end -%> <% end -%> </td> </tr> .... For the life of me I can''t figure out what I am doing wrong. - Michael Relavent Schema Scenarios: panicname_id int Panicnames: panic_code char(10) panic_name varchar(45) Notes: scenario_id int team_id int Teams: teamname varchar(45) Relavent Models: Scenario: belongs_to :panicname has_many :note Panicname: has_many :scenario Note: belongs_to :scenario belongs_to :team Team: has_many :note

Re: Problem accessing a field 2 tables away in an rhtml file
scenario.note (from the has_many :note declaration in the scenario model) therefore you''re trying to access a field of an array. you need to get the note from the array to access the field. so something like <% scenario.note.each{|note| unless (note.team.team_id ==1) %> <%=h note.team.teamname%> <% end } %> -- Andrew Stone _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
