DBIx::Class::InflateColumn::File.3pm

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DBIx::Class::InflateColumn::File - DEPRECATED (superseded by DBIx::Class::InflateColumn::FS)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