I am new to ruby on rails development. Please excuse me if my question
is too obvious. I am trying to upgrade from rails 3.0 to 3.2. I am stuck
at a point. I am running into this following error.
INTERNAL ERROR!!! undefined method `abstract_class?' for
What I found is that, the method 'abstract_class?' has been moved from
base.rb to inheritance.rb in rails 3.2.
I was actually trying to use execute the following statement when this
ActiveRecord::Base.connection.column_exists? klass.table_name, :user_id
Any ideas on work arounds
Thanks in advance.
