# NAME

DBIx::FixtureLoader - Loading fixtures and inserting to your database

# SYNOPSIS

    use DBI;

    use DBIx::FixtureLoader;

    my $dbh = DBI->connect(...);

    my $loader = DBIx::FixtureLoader->new(dbh => $dbh);

    $loader->load_fixture('item.csv');

# DESCRIPTION

DBIx::FixtureLoader is to load fixture data and insert to your database.

# INTEFACE

## Constructor

    $loader = DBIx::FixtureLoader->new(%option)

`new` is Constructor method. Various options may be set in `%option`, which affect

the behaviour of the object (Type and defaults in parentheses):

### `dbh (DBI::db)`

Required. Database handler.

### `bulk_insert (Bool)`

Using bulk\_insert or not. Default value depends on your database.

### `update (Bool, Default: false)`

Using `INSERT ON DUPLICATE` or not. It only works on MySQL.

### `ignore (Bool, Default: false)`

Using `INSERT IGNORE` or not. This option is exclusive with `update`.

### `delete (Bool, Default: false)`

DELETE all data from table before inserting or not.

### `csv_option (HashRef, Default: +{})`

Specifying [Text::CSV](https://metacpan.org/pod/Text%3A%3ACSV)'s option. `binary` and `blank_is_undef`

are automatically set.

### `skip_null_column (Bool, Default: false)`

If true, null data is not to be inserted or updated explicitly. It it for using default value.

NOTE: If this option is true, data can't be overwritten by null value.

## Methods

### `$loader->load_fixture($file_or_data:(Str|HashRef|ArrayRef), [%option])`

Loading fixture and inserting to your database. Table name and file format is guessed from

file name. For example, "item.csv" contains data of "item" table and format is "CSV".

In most cases `%option` is not needed. Available keys of `%option` are as follows.

- `table:Str`

    table name of database.

- `format:Str`

    data format. "CSV", "YAML" and "JSON" are available.

- `update:Bool`

    Using `ON DUPLICATE KEY UPDATE` or not. Default value depends on object setting.

- `ignore:Bool`

    Using `INSERT IGNORE` or not.

- `delete:Bool`

    DELETE all data from table before inserting or not.

## File Name and Data Format

### file name

Data format is guessed from extension. Table name is guessed from basename. Leading alphabets,

underscores and numbers are considered table name. So, `"user_item-2.csv"` is considered CSV format

and containing data of "user\_item" table.

### data format

"CSV", "YAML" and "JSON" are parsable. CSV file must have header line for determining column names.

Datas in "YAML" or "JSON" must be ArrayRef or HashRef containing HashRefs. Each HashRef is the data

of database record and keys of HashRef is matching to column names of the table.
