As far as I can tell from the code, that is pretty much what
has_attribute? does. However, upon reflection I realized that my
approach did not accommodate virtual attributes. So, I ended up with
this:
def attr_set_by_names(attr_names=[],param_hash={})
an = attr_names.to_ary
return self unless param_hash.kind_of?(Hash) && an.length > 0
an.each do |f|
self.send("#{f}=", "#{param_hash[f]}") if
self.method_exists?("#{f}=")
end
return self
end
Which handles every setter method available to the class.
You assistance, as always, is greatly valued.
