man DBIx::Class::Row () - Basic row methods

NAME

DBIx::Class::Row - Basic row methods

SYNOPSIS

DESCRIPTION

This class is responsible for defining and doing basic operations on rows derived from DBIx::Class::Table objects.

METHODS

new

  my $obj = My::Class->new($attrs);

Creates a new row object from column => value mappings passed as a hash ref

insert

  $obj->insert;

Inserts an object into the database if it isn't already in there. Returns the object itself.

in_storage

  $obj->in_storage; # Get value
  $obj->in_storage(1); # Set value

Indicated whether the object exists as a row in the database or not

create

  my $new = My::Class->create($attrs);

A shortcut for My::Class->new($attrs)->insert;

update

  $obj->update;

Must be run on an object that is already in the database; issues an SQL UPDATE query to commit any changes to the object to the db if required.

delete

  $obj->delete

Deletes the object from the database. The object is still perfectly usable accessor-wise etc. but ->in_storage will now return 0 and the object must be re ->insert'ed before it can be ->update'ed

get_column

  my $val = $obj->get_column($col);

Gets a column value from a row object. Currently, does not do any queries; the column must have already been fetched from the database and stored in the object.

get_columns

  my %data = $obj->get_columns;

Does CWget_column, for all column values at once.

set_column

  $obj->set_column($col => $val);

Sets a column value. If the new value is different from the old one, the column is marked as dirty for when you next call CW$obj->update.

set_columns

  my $copy = $orig->set_columns({ $col => $val, ... });

Sets more than one column value at once.

copy

  my $copy = $orig->copy({ change => $to, ... });

Inserts a new row with the specified changes.

store_column

  $obj->store_column($col => $val);

Sets a column value without marking it as dirty.

insert_or_update

  $obj->insert_or_update

Updates the object if it's already in the db, else inserts it.

is_changed

  my @changed_col_names = $obj->is_changed
