DBIx::Class::InflateColumn::File(3)  User Contributed Perl Documentation DBIx::Class::InflateColumn::File(3)



NAME
       DBIx::Class::InflateColumn::File -  DEPRECATED (superseded by DBIx::Class::InflateColumn::FS)

   Deprecation Notice
        This component has a number of architectural deficiencies that can quickly
        drive your filesystem and database out of sync and 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
       InflateColumn::File

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