Class::DBI Gotchas
Create and NOT NULL columns
When you call Person->create(), the object is created and inserted into the database in a single step
You might be tempted to do the following:
my $person = Person->create();
$person->name('Kevin Bacon');
$person->birthyear(1958);
$person->degrees_of_kevin(0);
But if the columns 'name', 'birthyear' and 'vacuity' are declared with NOT NULL, your database will throw an error.
Instead, you should fill in all the attributes:
my $person = Person->create({
name => 'Kevin Bacon',
birthyear => 1958,
degrees_of_kevin => 0,
});
