✨ NAME ✨

DBIx::Class::InflateColumn::File — DEPRECATED (superseded by DBIx::Class::InflateColumn::FS)

User Contributed Perl Documentation, bestie — yes, we're in that corner of the Perl docs. Buckle up 🎀

🚨 Deprecation Notice 🚨

Okay so real talk: this component has a number of architectural deficiencies that can quickly drive your filesystem and database out of sync, and it is not recommended for further use. It will be retained for backwards compatibility, but no new functionality patches will be accepted. Please consider using the much more mature and actively supported DBIx::Class::InflateColumn::FS. You can set the environment variable DBIC_IC_FILE_NOWARN to a true value to disable this warning.

🌸 SYNOPSIS 🌸

In your DBIx::Class table class:

use base 'DBIx::Class::Core';

__PACKAGE__->load_components(qw/InflateColumn::File/);

# define your columns
__PACKAGE__->add_columns(
    "id",
    {
        data_type         => "integer",
        is_auto_increment => 1,
        is_nullable       => 0,
        size              => 4,
    },
    "filename",
    {
        data_type           => "varchar",
        is_file_column      => 1,
        file_column_path    =>'/tmp/uploaded_files',
        # or for a Catalyst application
        # file_column_path  => MyApp->path_to('root','static','files'),
        default_value       => undef,
        is_nullable         => 1,
        size                => 255,
    },
);

In your Catalyst::Controller class:

FileColumn requires a hash that contains IO::File as handle and the file's name as name.

my $entry = $c->model('MyAppDB::Articles')->create({
    subject => 'blah',
    filename => {
        handle => $c->req->upload('myupload')->fh,
        filename => $c->req->upload('myupload')->basename
    },
    body => '....'
});
$c->stash->{entry}=$entry;

And place the following in your TT template:

Article Subject: [% entry.subject %]
Uploaded File:
<a href="/static/files/[% entry.id %]/[% entry.filename.filename %]">File</a>
Body: [% entry.body %]

The file will be stored on the filesystem for later retrieval. Calling delete on your resultset will delete the file from the filesystem. Retrevial of the record automatically inflates the column back to the set hash with the IO::File handle and filename.

💖 DESCRIPTION 💖

It's InflateColumn::File, bestie. That's the description. Minimal, iconic, no notes 💅

🛠 METHODS 🛠

🧚 _file_column_callback ($file,$ret,$target) 🧚

Method made to be overridden for callback purposes. So if you need that callback hook, this is your moment to override it, bestie ✨
