So there is no constant that returns any single state. I solved it by
writing a little initializer file:
class Hobo::Lifecycles::DeclarationDSL
def state_with_constants *args, &block
state_without_constants *args, &block
args.extract_options!
args.each { |name| @lifecycle.class_eval "#{name.to_s.upcase} =
'#{name}'" }
end
alias_method_chain :state, :constants
end
So now I can use any defined state a la HoboFields, to including it in
queries without any possible typo
MyClass::Lifecycle::ANYSTATE
Since the relavant part is just a simple line of code which make it also
consistent with HoboFields
@lifecycle.class_eval "#{name.to_s.upcase} = '#{name}'"
you might consider to include it in your code.
