I nned to get an associsted name from one table dependent on the related id value in another table when rendering the view but cant figure out the syntax to handle pontential empty values:-
i.e. docv.policy_id OR docv.standard_id will exist and therefore link back to the policies OR the standards table respectively but ONLY ONE will exist. Therefore I need to check the existance of each field before attempting to get the PolicyName OR StandrdsName from the related table otherwise the empty item gives me a '.nil value' error. <% @docversions.each do |docv| %> <tr> <td><% docv.modifier %></td> <td><%= docv.comment %></td> <td><%= docv.policy.PolicyName if docv.policy_id %></td> <td><%= docv.standard.StandardsName if docv.standard_id %></td> Can someone advise the syntax to use in the view to achieve this. I have also tried ....."if !docv.standard_id.empty?".
