State value exceptions?

[zaqwery]

In my model I had
include ActiveRecord::Transitions
state_machine do
state :submitted
state :valid
state :hidden
state :banned
end
And kept getting wrong number of arguments (1 for 0) until I renamed :valid to :validated . That closed an issue although word 'valid' isn't one of Ruby or Rails reserved words. There are many word exceptions for SQL databases but is that related to the particular field's value?

You should avoid using the same names in your state machine that AR implements as methods in your model. If you create state "valid", few additional methods will be created in your model (e.g. "valid?"), which will most probably break validations in your model. It's not a bug of Transitions.
