# DBIx::Class::Helper::Schema::Verifier::ColumnInfo(3pm)

Verify that Results only use approved column\_info keys

## NAME

DBIx::Class::Helper::Schema::Verifier::ColumnInfo - Verify that Results only use approved column\_info keys

## SYNOPSIS

```
 package MyApp::Schema;
 __PACKAGE__->load_components('Helper::Schema::Verifier::ColumnInfo');
 # optionally add some non-standard allowed keys
 sub allowed_column_keys {
   my $self = shift;
   my @keys = $self->next::method;
   push @keys, qw(is_serializable keep_storage_value remove_column);
   return @keys;
 }
```

## DESCRIPTION

`"DBIx::Class::Helper::Schema::Verifier::ColumnInfo"` verifies that none of your columns use non-approved configuration keys. DBIx::Class doesn't do any key verification, so this Helper makes sure you don't get burned by a typo like using `"autoincrement"` instead of `"is_auto_increment"`. If your schema uses a non-approved column config key, it will refuse to load and instead offer a hopefully helpful message pointing out the error.

## METHODS

### allowed\_column\_keys()

It's entirely possible that you would like to use some non-default config keys, especially if you use some column-extension components. Override this method in your schema and append your new keys to the list returned by the superclass call.  The overridden method must return a list of keys.

```
 sub allowed_column_keys {
   my $self = shift;
   my @keys = $self->next::method;
   # modify @keys as needed
   return @keys;
 }
```
