Problem with initial_state and mongoid

[simonc]

Using mongoid (v3.0.17) I have an issue with the initial state setting.

product = Product.new
product.current_state #=> :available
product.valid? #=> false
product.errors #=> ... {:state=>["can't be blank", "is not included in the list"]}

ActiveModel#Transitions.set_initial_state tests for has_attribute?(:state).

self.state ||= self.class.get_state_machine.initial_state.to_s if self.has_attribute?(:state)

Mongoid returns false if the field is not set. Maybe it should only check respond_to?(:state=) don't you think ?

Excellent, thanks!

@simonc I'm afraid that commit broke something in transitions: #76
Do you think you could look into this and come up with another solution?
I'm afraid I can't do this myself since I know exactly ZERO about mongoid.
Otherwise I'm afraid I'll have to revert that commit since I value the use case in the referenced issue a little higher than mongoid support.

I'm sorry, but I had to revert this pull request - let me know if you come up with something that fixes mongoid support again without breaking other functionality and I'll be more than happy to merge that again..:)

No problem. I'm sorry, I didn't have time to take a new look at the issue :/
I'll see what I can do but I have a lot on my plate right now :)
