Bug with dirty models in integer fields

Reported by Felipe Giotto | December 5th, 2008 @ 05:26 PM | in 2.x

There's a problem with dirty models.

I can use the following example:

There's a model named Person, with name(string) and age(integer).

p = Person.first p.update_attributes :age => 0, :name => 'Felipe'

This SQL runs: UPDATE people SET age = 0, name = 'Felipe' WHERE id = 1 Then, I typed:

p.update_attributes :age => '', :name => 'John'

This SQL runs: UPDATE people SET name = 'John' WHERE id = 1

When the value changes from 0 to '' (supposed to be stored as nil), Rails didn't recognize it as a change!
