Generating a random number

Would something like this do the trick?

random = Array.new(6){rand(6)}.join

What I did:

  def self.generate_invoice_id     record = Object.new     while record       random = rand(999999999)       record = find(:first, :conditions => ["invoice_id = ?", random])     end     return random   end

Put that in the model and I get a random invoice number when I need it..

How about something like:

"%09d" % rand(1000000000)

Or... this way seems even better:

Array.new(9){rand 10}.join

Where 9 can be replaced by however many digits you want.

Thanks everyone for your help. A couple different ways actually worked that you all suggested.

That was just driving me crazy not being able to figure out the small details of a random number in Rails. Every language does it slightly differently too.

Thanks,
