[web2py] Re: How to -- Popup window: Record already exists are you sure you want to upload file?
until the user clicks on submit, there's no way for web2py (or you) to
know the name of the file being uploaded beforehand, using a normal input
type=file. it's just not how the browsers work.

Hello,
I want to create a popup window that lets the user click okay to continue
uploading the file if it already exist in the database.
I created a separate table which tracks all the files uploaded in the
database. I then append that to a list and check if the filename is in
there.
My code looks like this:
def my_form_processing(form):
fileUploadList = []
fileToCheck = form.vars.blah.filename
filesUploaded = db().select(db.myFileTracker.ALL)
for line in filesUploaded:
if line.file_name not in fileUploadList:
fileUploadList.append(line.file_name)
if fileToCheck in fileUploadList:
btn = form.element('input',_type=submit)
btn[_onclick] = return confirm('File Already exists in database,
are you sure you want to resubmit?');
def processing():
form = FORM(TABLE(TR(TD('upload file:', INPUT(_type='file',
_name='blah')))
if form.process(onvalidation=my_form_processing).accepted:
response.flash = Processed file without errors!
the problem is it sets the element after the file uploads and i'm not sure
how I can make it pop up before the file actually gets uploaded.
Appreciate any help!
