Hello... I need to do the following in rails: I have a string with the following composition: AAA-BBB-2008-000001 The first to groups are strings, named @string1 and @string2. The third is the year, (reflected using Time.now.strftime("%Y")) and the last part is an integer, @integer1. I'm using a PostgreSQL 8 database and I need to put that composition on a string.I have no problem with the string variables and the year. The catch here is the integer, it increases everytime I do a new registry and, when a new year comes, it resets to 1. More over, I need the integer to be 6-digit.I don't know how to do that, but I know the logic of th increments: When the integer is 10, I need it to be 000010; when it's 100, 000100; 1000 => 001000 and so on. And let's suppose one of our string changes, for example. It also must resets the integer to 1. As you can see, it's a unique composition. As the id from the database keeps increasing, that number won't work on me. I need to set it apart, without using that number. And that count must be kept, whenever I log in to my app. Is it hard to do this stuff? Greetings... The N.

you can use sprintf formatting for the integer: @integer1 = 10 int_formatted = "%06d" % @integer1 # returns "000010" I don't understand the other requirements enough to help further
