'{namespace}_{status}?' helper not working, e.g. 'status_active?', if value is a symbol

[fruwe]

Hi, great plugin, thanks.

I am using state_machine with the enum_column3 gem.
It seems, that the enum_column3 gem sets the attribute values in the model instance to symbols, rather than strings

code:

class XXX < ActiveRecord::Base
  state_machine :status, :initial => :register, :namespace => :status do
    state :register, :active, :inactive
    event :inactive do
      transition [:active] => :inactive
    end
  end
end

status_active? and can_inactive_status? should be true in this example, but only the "can" helper is:

irb(main):014:0> c = XXX.first
irb(main):014:0> c.status
=> :active
irb(main):015:0> c.status_active?
=> false
irb(main):015:0> c.can_inactive_status?
=> true

The code responsible for this is

module StateMachine
  class State
    [...]

    def initialize(machine, name, options = {}) #:nodoc:
      [...]
      @value = options.include?(:value) ? options[:value] : name && name.to_s
      [...]
    end

    [...]

    def matches?(other_value)
      matcher ? matcher.call(other_value) : other_value == value
    end

    [...]
  end
end

using either
@value = options.include?(:value) ? options[:value] : name
or
matcher ? matcher.call(other_value) : other_value.to_s == value.to_s
would fix the problem.

I know, that probably using e.g. "state :active, :value => :active" could work, but rather would like to avoid doing that, since I would have to fix many places, and I think that the gem should be more specific about it, since the "can_{status}{namespace}?" works, but not the "{namespace}{status}?" helper.

Let me know, what you think.

Thanks

I'm having the same problem. Anyone looked at this?

Same problem here, I'm having to use 'state_name == ' to get around this issue.

Using mongoid 3, and defining states as numbers (i.e. 'state :open, value: 0'). The helper methods are defined, but always return false.

Also having the same issue. Only with some states however. Things like prospective? and prospective_public?
