There is a much easier solution to all of this. Utilize the try() method that comes with ActiveSupport:
<p> <%= @post.try(:user).try(:name) %> </p> try() calls a method and catches exceptions, returning nil instead. Try is added to the main Object class, so even nil objects have the method, hence your ability to chain them together.... -casey On Jun 29, 5:50 am, Michael Pavling <pavl...@gmail.com> wrote: > On 29 June 2010 10:37, Carsten Gehling <li...@ruby-forum.com> wrote: > > > Yup it is a very neat solution, that I will adapt to.
