# Simple bijective function

#   Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047

ALPHABET =
  "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
  # make your own alphabet using:
  # (('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a).shuffle.join

Transactions

As your business logic gets complex you may need to implement transactions. The classic example is a bank funds transfer from account A to account B. If the withdrawal from account A fails then the deposit to account B should either never take place or be rolled back.

Basics

All the complexity is handled by ActiveRecord::Transactions. Any model class or instance has a method named .transaction. When called and passed a block, that block will be executed inside a database transaction. If there's an exception raised, the transaction will automatically be rolled back.

Example

- (void)displayValidationError:(NSError *)anError {
    NSLog(@"error domain, %@",[anError domain]);
    if (anError && [[anError domain] isEqualToString:@"NSCocoaErrorDomain"]) {
        NSArray *errors = nil;
        
        // multiple errors?
        if ([anError code] == NSValidationMultipleErrorsError) {
            errors = [[anError userInfo] objectForKey:NSDetailedErrorsKey];
        } else {
            errors = [NSArray arrayWithObject:anError];
