Hi. Last month i had some questions about uploading PDF's in a Catalyst app,
and J. Shirley gave me some helpful advice. I got it working, or so i thought,
and then put the project aside as the users werent ready for it.
I just got back to it and i see that theres some kind of problem. The PDF's
when displayed in my app are mangled; they are visible but there are display
problems with them (parts cut off, or the image shifted). I dont know if it was
like this originally and i just didnt notice, or if something has changed, but
i dont know where to look and would be greatful for a push in the right
direction.
Im storing them in a MySQL database, with the PDF field a MEDIUMBLOB so large
enough for a 16M file.
My upload code is basically:
my $upload = $c->request->upload('document');
my $document = $c->model->create({ document => $upload->slurp,
type => $upload->type,
filename => $upload->basename});
And then my display code is:
# $document is already grabbed from the database
$c->res->output($document); # overloaded to stringify to $document->document
$c->res->headers->content_type($document->type);
$c->res->headers->header('Content-Disposition' => 'attachment;
filename=".$document->filename);
(As another question, is this the right way to get the filename to the browser?
The docs for HTTP::Headers didnt say anything about this.)
Theres a length difference when i download. A test file i uploaded is 165681
bytes, but when i upload and save it to the database, and then display the file
from my app and save it, its 165685 bytes--four more.
What should i be looking at to try to figure this out?
Thanks.
Jen
