How can I call a nested hash of methods names on an object?
For example, given the following hash:
hash = {:a => {:b => {:c => :d}}}
I would like to create a method that, given the above hash, does the equivalent of the following:
object.send(:a).send(:b).send(:c).send(:d)
The idea is that I need to get a specific attribute from an unknown association (unknown to this method, but known to the programmer).
I would like to be able to specify a method chain to retrieve that attribute in the form of a nested hash. For example:
hash = {:manufacturer => {:addresses => {:first => :postal_code}}}
car.execute_method_hash(hash)
=> 90210
