Ironruby core - Jul 2010 - Ordered active record attributes hash

Hi All:

I''m trying to traverse the active record attributes hash in the order
it
was created.
------------------
a = Table.find_by_sql("select * from sometable")

a.each { |row| puts row.to_yaml
# prints the the attributes in the order coming from the select
statement
# which is exactly how I would like to process the columns
puts row.attributes.to_yaml
# shows the attributes in sorted order...
}

------------------
Is that a problem with activerecord?

how I could solve the issue?

Hi all,

I found the solution for this puzzle:

Active record, when you call the procedure attributes, it sorts the
attributes by key, so, by working in the following way, that works
correctly:

row.instance_variable_get(:@attributes).to_yaml

instead of

row.attributes.to_yaml

Thank you anyways
