You received this
yes, you are right, my bad, there is readable = False, set for the upload

perhaps you can use validators on form level.
e.g.
requires = IS_UPLOAD_FILENAME(extension='pdf')

You are right
I wrote before checking again.
Last time i checked, after removing the "required", the record could not be
saved.
Then checked the sqlite db via firefox plugin and still the required was
set at the sqlite db.
So far so good more on this later if problems.

Humm required is set at the DAL level I don't see how this could create
problems due to sqlite.

What does "writable=false if forms" mean and WHAT should I apply this to?
And where should I plug this "URL('mydownload', ... ) into? Sorry, but I
understand if you just write some web2py-specific code completely out of
contex. It requires some explanation.

Ok so I've already figured out what you meant.
I should set 'writable' attribute of this field in db_wizard.py to False in
order to prevent this field from being overwritten in forms. Then change
type from 'string' to 'upload' and apply URL('mydownload') to 'represent'
attribute of this field
Than it is easy. make it writable=false if forms.
Store your filename in the the upload field. But instead of
URL('download',)
use
URL('mydownload',)
Where:
def mydownload():
fullname = os.path.join(os.path.join, 'private', request.args(0))
response.stream(fullname)
On Wed
f_invoice_file_path is location where the file is stored by myself, because
I generate these files myself and I save them myself as well. It contains
whole path to the file ( with the filename and its extension ). They are
stored under "private" directory with the structure I described above. I
Let me understand this better f_invoice_file_path is the location where the
file is supposed to be stored or is it the full path including the desired
filename? Do you handle the file writing or should web2py do it
automatically?

My bad:
Assigning to a form.vars item before calling to .process() works
The issue is that the first code posted by Joe tests for the boolean value

This
form=SQLFORM(db.fileobject)

A possible workaround (
Setting writable to False is probably the best way to keep that field out
of the form -- that's why I suggested setting the default value of the
field instead. Does that not work?

I was trying to keep the filename out of the generated form since I want it
set "automatically" in the process of uploading the document. Is there a
better way to accomplish that?
BTW, the test "if request.vars.upload" does not work. It returns "False"
even if the upload field has been set.
I see. I think the problem is that you have set the writable attribute of
the filename field to False. In that case, try setting the default value of
that field:
if request.vars.upload:
db.fileobject.filename.default = request.vars.upload.filename
form = SQLFORM(db.fileobject)

Hi Anthony --
I want the opposite of this -- I want the actual text filename, not the

Are you saying you want the name in the "filename" field to be encoded into
the string stored in the "upload" field so the file has the name in the
"filename" field upon download? If so, then try:
if request.vars.upload and request.vars.filename:
request.vars.upload.filename = request.vars.f
Other form elements aren't stored in the session -- when the form
submission comes in, they are in request.vars, and they can be moved to
form.vars and returned with the form (no need to put anything in the
session). The file itself, on the other, cannot be returned with the form,
so you have t
So how does it work for other form elements? I'm guessing they are stored
in session. So the way to go would be to store the uploaded file in session
too and then on form resubmission check what to display. If file is in
session the input field should look as on update of an existing object
(i.
This is tricky. When the form is submitted, it doesn't send the location of
the file on the user's computer -- it sends the actual file. Even if you
knew the location of the file on the user's computer, you couldn't
pre-populate the form field with that value because browsers won't allow it

Note, I believe response.stream will handle setting the Content-Type header
for you.
Great, response.stream did it!
The exact code I end up using (in case someone else needs to get
around the 'no_table.XXX' file name scenario). Another reason I like
this approach (vs

response.download checks the db to get the uploadfolder from the upload
field (which you don't have). Instead, you might be able to use
response.stream directly:
import os
filename = [code to get filename from db]
response.stream(os.path.join(request.folder, 'uploads', filename),
