NAME

6       DBIx::Class::Helper::Schema::Verifier - Verify the Results and
7       ResultSets of your Schemata

SYNOPSIS

10        package MyApp::Schema;
11
12        __PACKAGE__->load_components('Helper::Schema::Verifier');
13
14        sub result_verifiers {
15          (
16             sub {
17                my ($self, $result, $set) = @_;
18
19                for ($result, $set) {
20                   die "$_ does not start with the letter A" unless m/^A/
21                }
22             },
23             shift->next::method,
24          )
25        }

DESCRIPTION

28       "DBIx::Class::Helper::Schema::Verifier" is a minuscule framework to
29       assist in creating schemata that are to your very own exacting
30       specifications.  It is inspired by my own travails in discovering that
31       "use mro 'c3'" is both required and barely documented in much Perl
32       code.  As time goes by I expect to add many more verifiers, but with
33       this inaugural release I am merely including
34       DBIx::Class::Helper::Schema::Verifier::C3.
35

INTERFACE METHODS

37   result_verifiers
38       You must implement "result_verifiers" in your subclass of "::Verifier".
39       Each verifier gets called on the schema and gets each result and
40       resultset together as arguments.  You can use this to validate almost
41       anything about the results and resultsets of a schema; contributions
42       are warmly welcomed.
43

MORE ERRORS

45       Initially I kept this module simple, but after using it in production
46       at ZipRecruiter <https://www.ziprecruiter.com> I found that showing the
47       user the first error that occurred and then giving up was pretty
48       annoying.  Now "Schema::Verifier" wraps both "load_namespaces" in
49       DBIx::Class::Schema and "load_classes" in DBIx::Class::Schema and shows
50       all the exceptions encoutered as a list at the end of loading all the
51       results.
