NAME

DBIx::DataFactory - factory method maker for inserting test data

SYNOPSIS

# schema
CREATE TABLE test_factory (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `int` int,
  `double` double,
  `string` varchar(255),
  `text` text DEFAULT NULL,

  PRIMARY KEY (id)
) DEFAULT CHARSET=binary;

# in your t/*.t
use DBIx::DataFactory;
my $factory_maker = DBIx::DataFactory->new({
    username => 'nobody',
    password => 'nobody',
    dsn      => 'dbi:mysql:dbname=test_factory;host=localhost',
});
$factory_maker->create_factory_method(
    method   => 'create_factory_data',
    table    => 'test_factory',
    auto_inserted_columns => {
        int => {
            type => 'Int',
            size => 8,
        },

            size => 10,
        },
    },

DESCRIPTION

This module helps you to make factory method for inserting data into database. You can use this for fixture replacement.

METHODS

$class->new(%args)

Create a new DBIx::DataFactory object.

my $factory_maker = DBIx::DataFactory->new({
    username => 'nobody',
    password => 'nobody',
    dsn      => 'dbi:mysql:dbname=test_factory;host=localhost',
});

Set up initial state by following parameters.

  • username

    Database username.

  • password

    Database password

  • dsn

    Database dsn

$self->create_factory_method(%args)

This installs the method, which helps inserting data into database, in the DBIx::DataFactory package by default.

$factory_maker->create_factory_method(
    method   => 'create_factory_data',
    table    => 'test_factory',
    auto_inserted_columns => {
        int => {
            type => 'Int',
            size => 8,
        },
        string => {
            type => 'Str',
            size => 10,
        },
    },
);

if this is the case, this make the method named 'create_factory_data'. you can pass all columns value you defined in schema.

my $values = $factory_maker->create_factory_data(
    int    => 5,
    string => 'string',
    text   => 'test text',
);

# this makes following data.
+----+-----+--------+-----------+
| id | int | string | text      |
+----+-----+--------+-----------+
|  1 |  5  | string | test text |
+----+-----+--------+-----------+


my $values = $factory_maker->create_factory_data;

# this makes following data
+----+----------+------------+------+
| id | int      | string     | text |
+----+----------+------------+------+
|  2 | 59483011 | 9svzODgYyz | NULL |
+----+----------+------------+------+

Parameters

  • method

    Required parameter. method name you want to create.

  • table

    Required parameter. database table name.

  • dsn

    optional parameter. database dsn.

  • username

    optional parameter. database username.

  • password

    optional parameter. database password.

  • auto_inserted_columns

    optional parameter. if you have the table column which you want to insert data into automatically by default, you can specify this parameter.

    for example, if you have columns named 'int', 'string', and 'text', you can specify following.

    $factory_maker->create_factory_method(
    method   => 'create_factory_data',
    table    => 'test_factory',
    auto_inserted_columns => {
        int => {
            type => 'Int',
            size => 8,
        },
        string => {
            type => 'Str',
            size => 10,
        },
        text => sub { String::Random->new->randregex('[a-z]{50}') }
    },
);

    if passed hashref, the method inserts data which is defined in specified type class automatically by default. see also DBIx::DataFactory::Type.

    if passed coderef, the method inserts value which the code returns.

    Of cource, if you specify column value in installed method, the setting for the column is not used.

  • install_package

    optional parameter. if you want to install the factory method to package except DBIx::DataFactory, please specify.

    $factory_maker->create_factory_method(
    method          => 'create_factory_data',
    table           => 'test_factory',
    install_package => 'test::DBIx::DataFactory',
);

add_type

you can add type class which define the rule of inserting data. See also DBIx::DataFactory::Type.

DBIx::DataFactory->add_type('DBIx::DataFactory::Type::Test');
