Catching frozen hashes


I have been wrestling w/ the frozen hash problem in a script and I’m
trying to catch this at the source where it crashes the program in
flames. Unfortunately, when I look at the errors, the failure is way
up in the active record ancestery chain.

Here’s the first entries in the error output:


[]=' /opt/local/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:1877:inunserialize_attribute’
read_attribute' /opt/local/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:1489:in[]’

Also, I know you can test to see if a hash is frozen by using the
frozen? method.

I just don’t know where test and rescue this exception.

Thanks for any help!
