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 = Topic.new
t.title = { 'a' => 'b' }
t.title # => { 'a' => 'b' }
t.save
t.reload
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?

    +1 for serialize/deserialize

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