> All the code will be used in a Rails 3 app.

> Let's say I have an article model which looks something like this:

> state_machine :state, :initial => :new do
>    event :submit_for_approval do
>      transition [:new, :declined] => :pending
>    end

>    event :decline do
>      transition [:pending] => :declined
>    end

>    event :approve do
>      transition [:pending, :declined] => :published
>    end
> end

> This will give me the following methods (among others):

> submit_for_approval, approve and decline.

> Let's say I would like to keep a log of whoever performed these
> actions on the given article.
> I know there is something called state_machine-audit_trail, however
> this only logs the changes.
> I would like to pass in the invoker of the change in the
> submit_for_approval, approve and decline methods. How can I achieve
> this ?

> If this is not possible or considered a bad practice what would you
> suggest ?
