Rails - Feb 2006 - ordering of params

I have a few long forms.  I want to email out the user''s response on
the form.

So I have something like:

# View
<%= text_field ''answer'', ''name'' %>
Name <br />
<%= text_field ''answer'', ''email'' %>
Email <br />
......

# Controller
def form_submit
  answers = params[:answers]
  email_text = "New form submission receieved"
  answers.each do |question, answer|
    email_text << "#{ question.humanize }: #{ answer }\n"
  end
  # send email
end

However, I don''t iterate through the answers in the order that they
were in the form, the answers are retrieved from params in a random
order (since hashes aren''t ordered).

Is there any way to do something like this and keep a sensical order
to the email?

Thanks,
Joe

I think this is kinda ugly, but it should do the trick:

QUESTION_ORDER = %w{ name email ... }

def form_submit
  answers = params[:answers].sort_by { |question, _| QUESTION_ORDER.index(
question.to_s) }
  email_text = "New form submission received"
  answers.each do |question, answer|
    email_text << "#{ question.humanize }: #{ answer }\n"
  end
end
