changed_attributes returning inconsistent data

[marceloeloelo]

Let's say I have an Account model which has some varchar columns. I'm seeing strange behavior when calling changed_attributes:

> Account
# => Account(ID: integer, Name: varchar, Address: string)

> account = Account.find(1)
# => #<Account ID: 1, Name: "ABCDE", Address: "123 Street">

> account.changed_attributes
# => {}

> account.save
# => true

> account.changed_attributes
# => { "Name" => "ABCDE" }

As you can see, there was no change to the Name attribute but it's still being included in the changed_attributes response after the account object was saved.

@metaskills I can't explain this, do you have an idea on what might be going on? Have you experienced any similar issue with varchar?

Thanks

I have not, we certainly would not test the test if this were the case. Did you ever find out what the issue was? Going to close this but feedback still welcome.
