Hi -
What is the best way to create a nested hash from an array of objects?
Here''s what I''m trying to do, take my array of objects and use
the
attribute ''position'' as a key for each nested hash. The
nested hash
will contain the other array attributes.
Example:
[#<Spec id: 4057, position: 1, name: "Tonnage", english_unit:
"T",
metric_unit: "t">,
[#<Spec id: 4058, position: 2, name: "Spindle", english_unit:
"T",
metric_unit: "t">]
This is what I want to end up with from the above:
{1 => {:name => "Tonnage", :english_unit => "T",
:metric_unit => "t"},
2 => {:name => "Spindle", :english_unit => "T",
:metric_unit => "t"}}
I''ve tried different methods of enumerating but can''t quite
get what I
want.
Thanks for any help!

Looks like you''re starting with ActiveRecord''s so you could possibly take advantage of: spec_hash = Spec.find(4057).attributes and glue something together.
