Hi,
I recently added 2 serialized columns in my class Server :
class Server < ActiveRecord::Base
serialize :visa, Hash
serialize :appli, Array
...
No problem in my controller and my application and everything works as
expected : Excel exports following the "visa" Hash or
"appli" Array
are ok.
But since I added the visa Hash, I can''t load the record with such a
serialized column in the console window :
>> s=Server.find_by_nom "a_server"
ActiveRecord::SerializationTypeMismatch: visa was supposed to be a
Hash, but was a String

Any Idea ? Is it a bug ?
Thanks a lot for your help.
