Subject: How to iterate of the attributes of an object?

I need to build a string of all populated attributes of a given object.

I need to get the attribute name and it's value

Also,the object may have 10 attributes, but I'm only interested in the
attribute that are not nil.



here's a sample object:
foo = Foo.new(:bar => 'baz', :bar2 => 'baz2', :bar3 => 'baz3')


ultimately what I want is this as a string like this:
 ":bar => 'baz', :bar2 => 'baz2', :bar3 => 'baz3'"

code should be something like this? (sorry I'm a newbie)

   s = ""

   foo.instance_values.each  do |v|
      s += ":#{v.name} => #{v.value}"
   end

   s.split(",")
