Issue with Rails 4.2

[epinault]

I cannot seem to make it work with ActiveRecord. The initial state is never set correctly. I am using Ruby 2.1.x and Rails 4.2.x. Gem is 0.4.0

I have a Model that has a state field. State machine goes from pending, to starting to running to done

So pretty simple. But something is not working right (was working with 4.0 and the older version of state_machine (the one your forked from).)

So I am upgrading rails and finding that the old one is unmaintained and trying yours. But still not working properly for me

 f = FeedCrawlingRun.new
=> #<FeedCrawlingRun:0x007fc7b4ebccf0
 id: nil,
 started_at: nil,
 stopped_at: nil,
 state: nil,
 statistics: {},
 downloaded_files: {},
 feed_id: nil,
 created_at: nil,
 updated_at: nil>

Notice that state is nil . if I try to created it, it is never initialize correctly either

but if I do a f.starting? or f.pending? , it show the correct state. The state also shows with f.state.. But it is never saved to DB...

what am I missing?

Here also another session

Nevermind. Found a stackoverflow that points to an extra gem to install (the state_machines-activerecord one)
