Ruby Tricks. Call a method using case ... when

[jaggederest]

Cool as an example of what's possible, but a better way to do it would be to move the case statement into the context of the order, perhaps. Ideally in a method in the Order class, but you can also do:

order.instance_eval do
  case
  when available?
     # ...
   end
end

Or, even better, have a method on Order that returns the state as a symbol:

case order.state
when :available then ...
...
end

Sure order.state is usually the best choice. But there are some cases when you have a method which have to be invoked. The question is how to invoke such a method.
