DBIx::Class::InflateColumn::File - DEPRECATED (superseded by DBIx::Class::InflateColumn::FS)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