NAME
DBIx::Class::InflateColumn::File - map files from the Database to the filesystem.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.
