ActiveRecord should raise an exception sometimes

Reported by Aaron Patterson | September 22nd, 2010 @ 10:48 PM | in 3.1

I'm filing this so I don't forget. When you set a hash value as a model attribute, AR silently stores the value in the to_s form. When you reload the object, you get a string rather than a hash. This is unexpected:

t =
t.title = { 'a' => 'b' }
t.title # => { 'a' => 'b' }
t.title # => 'ab'

    Assuming that title is defined as string and is not declared as serialize.

    Is the fix going to be serialize the value behind the scene and then desearialize?

    The fix should be to raise an exception unless you've declared the attribute as serialized.
