Re: Sorting an array of string-integer identifiers
Try this:
my_array.sort do |item1, item2|
first_1=item1.first
first_2=item2.first
regex = /\w*_\d*_(\w*)_(\d*)/
first_1 =~ regex
letters_1 = $1
numbers_1 = $2.to_i
first_2 =~ regex
letters_2 = $1
numbers_2 = $2.to_i
if letters_1 == letters_2
numbers_1 <=> numbers_2
else
letters_1 <=> letters_2
end
end

I got the answer.
Wrote like this
array.sort_by {|i| str_to_num(i[0]) } &
def str_to_num(str)
code = str.split(''_'')[2]
regex = Regexp.new "^question_(\\d+)_#{code}_(\\d+)$"
str =~ regex
[$1.to_i, $2.to_i]
end
Thanks

It seems to be unusual in the Rails form-handling patterns to have this matter at all. It''s a hash, and those don''t have an explicit order anyway (until Ruby 1.9.3).
