NAME

Otogiri - A lightweight medicine for using database

SYNOPSIS

    use Otogiri;
    my $db = Otogiri->new(connect_info => ['dbi:SQLite:...', '', '']);
    
    my $row = $db->insert(book => {title => 'mybook1', author => 'me', ...});
    print 'Title: '. $row->{title}. "\n";
    
    my @rows = $db->select(book => {price => {'>=' => 500}});
    for my $r (@rows) {
        printf "Title: %s \nPrice: %s yen\n", $r->{title}, $r->{price};
    }
    
    $db->update(book => [author => 'oreore'], {author => 'me'});
    
    $db->delete(book => {author => 'me'});
    
    ### insert without row-data in response
    $db->fast_insert(book => {title => 'someone', ...});
    
    ### using transaction
    do {
        my $txn = $db->txn_scope;
        $db->insert(book => ...);
        $db->insert(store => ...);
        $txn->commit;
    };

DESCRIPTION

Otogiri is one of ORM. A slogan is "Schema-less, Fat-less".

ATTRIBUTE

connect_info (required)

   connect_info => [$dsn, $dbuser, $dbpass],

You have to specify dsn, dbuser, and dbpass, to connect to database.

inflate (optional)

    use JSON;
    inflate => sub {
        my ($data, $tablename) = @_;
        if (defined $data->{json}) {
            $data->{json} = decode_json($data->{json});
        }
        $data->{table} = $tablename;
        $data;
    },

You may specify column inflation logic.

Specified code is called internally when called select(), search_by_sql(), and single().

deflate (optional)

    use JSON;
    deflate => sub {
        my ($data, $tablename) = @_;
        if (defined $data->{json}) {
            $data->{json} = encode_json($data->{json});
        }
        delete $data->{table};
        $data;
    },

You may specify column deflation logic.

Specified code is called internally when called insert(), update(), and delete().

METHODS

new

    my $db = Otogiri->new( connect_info => [$dsn, $dbuser, $dbpass] );

Instantiate and connect to db.

Please see ATTRIBUTE section.

insert

    my $row = $db->insert($table_name => $columns_in_hashref);

Insert data. Then, returns row data.

fast_insert

    $db->fast_insert($table_name => $columns_in_hashref);

Insert data simply.

select

    my @rows = $db->select($table_name => $conditions_in_hashref [,@options]);

Select from specified table. Then, returns matched rows as array.

single

    my $row = $db->single($table_name => $conditions_in_hashref [,@options]);

Select from specified table. Then, returns first of matched rows.

search_by_sql

    my @rows = $db->search_by_sql($sql, @bind_vals);

Select by specified SQL. Then, returns matched rows as array.

update

    $db->update($table_name => [update_col_1 => $new_value_1, ...], $conditions_in_hashref);

Update rows that matched to $conditions_in_hashref.

delete

    $db->delete($table_name => $conditions_in_hashref);

Delete rows that matched to $conditions_in_hashref.

do

    $db->do($sql, @bind_vals);

Execute specified SQL.

txn_scope

    my $txn = $db->txn_scope;

returns DBIx::TransactionManager::ScopeGuard's instance. See DBIx::TransactionManager to more information.

last_insert_id

    my $id = $db->last_insert_id([@args]);

returns last_insert_id. (mysql_insertid in MySQL or last_insert_rowid in SQLite)
