I have recently upgraded my Rails app to 2.3. I am using STI where I
have class called BaseProfile that is extended by IndividualProfile. I
have some assocations that are defined in BaseProfile but I have been
getting errors when views reference those relationships, e.g.
undefined method `primary_user?' for #<IndividualProfile:0x7fcb3ecea278>
The primary_user? is defined in parent class. This code used to work
with older version of Rails. Is there a fix for this?
You weren't kidding about the "older version" part, were you? That
method was deprecated back in 0.9.5(!!) (January 2005) and went away
several versions later. Even the deprecation warning is gone now.
The now-long-gone deprecation message recommended that you use ==
instead; you'll need to check if you were passing the second argument
(force_reload) or not.
