NAME

Catalyst::Action::Serialize::SimpleExcel - Serialize to Excel files

SYNOPSIS

Serializes tabular data to an Excel file. Not terribly configurable, but should suffice for simple purposes.

In your REST Controller:

package MyApp::Controller::REST;

use parent 'Catalyst::Controller::REST';
use DBIx::Class::ResultClass::HashRefInflator ();
use POSIX 'strftime';

__PACKAGE__->config->{map}{'application/vnd.ms-excel'} = 'SimpleExcel';

sub books : Local ActionClass('REST') {}

sub books_GET {
    my ($self, $c) = @_;

    my $books_rs = $c->model('MyDB::Book')->search({}, {
        order_by => 'author,title'
    });

    $books_rs->result_class('DBIx::Class::ResultClass::HashRefInflator');

    my @books = map {
        [ @{$_}{qw/author title/} ]
    } $books_rs->all;

    my $authors_rs = $c->model('MyDB::Author')->search({}, {
        order_by => 'last_name,middle_name,last_name'
    });

    $authors_rs->result_class('DBIx::Class::ResultClass::HashRefInflator');

    my @authors = map {
        [ @{$_}{qw/first_name middle_name last_name/} ]
    } $authors_rs->all;

    my $entity = {
        sheets => [
            {
                name => 'Books',
                header => ['Author', 'Title'], # will be bold
                rows => \@books,
            },
            {
                name => 'Authors',
                header => ['First Name', 'Middle Name', 'Last Name'],
                rows => \@authors,
            },
        ],
        # the part before .xls, which is automatically appended
        filename => 'myapp-books-'.strftime('%m-%d-%Y', localtime)
    };

    $self->status_ok(
        $c,
        entity => $entity
    );
}

In your javascript, to initiate a file download:

// this uses jQuery
function export_to_excel() {
    $('<iframe '
     +'src="/rest/books?content-type=application%2Fvnd.ms-excel">')
    .hide().appendTo('body');
}

Note, the content-type query param is required if you're just linking to the action. It tells Catalyst::Controller::REST what you're serializing the data as.

DESCRIPTION

Your entity should be either an array of arrays, an array of arrays of arrays, or a hash with the keys as described below and in the "SYNOPSIS".

If entity is a hashref, keys should be:

sheets

An array of worksheets. Either sheets or a worksheet specification at the top level is required.

filename

Optional. The name of the file before .xls. Defaults to "data".

Each sheet should be an array of arrays, or a hashref with the following fields:

name

Optional. The name of the worksheet.

rows

Required. The array of arrays of rows.

Optional, an array for the first line of the sheet, which will be in bold.

column_widths

Optional, the widths in characters of the columns. Otherwise the widths are calculated automatically from the data and header.

If you only have one sheet, you can put it in the top level hash.
