Salesforce originally used case-sensitive 15-character alphanumeric IDs. Later on, added three error-correcting characters to make their 18-character ID.

Usage

SalesforceIdFormatter.to_18:

  • Converts a 15-char String to its equivalent 18-char ID as a String: SalesforceIdFormatter.to_18('70130000001tcyI') # => '70130000001tcyIAAQ'`
  • Leaves a 18-char String unaltered: SalesforceIdFormatter.to_18('70130000001tcyIAAQ') # => '70130000001tcyIAAQ'
  • Raises SalesforceIdFormatter::InvalidId if the given ID doesn't follow Salesforce's conventions http://www.salesforce.com/us/developer/docs/api/Content/field_types.htm#i1435616 TL;DR: 15 or 18 alphanumeric, case-sensitive chars

SalesforceIdFormatter.to_15 applies the same rules, returning 15-char IDs instead.

Code is a modified version of https://gist.github.com/jbaylor-rpx/2691624 (original does seemt to calculate control digits correctly)
