Thanks to Calvin Morrison's excellent work here is a really simple solution
to uploading multiple items. I need help validating multiple files. I can
upload one .txt file without issue; however, if i choose more than one it
will not pass validation. Can someone tell me what kind of loop or
function would help me validate files BEFORE they are uploaded? Also, if
there is a more elegant way to code the controller please let me know.
Model:
db.define_table('uploads',
Field('username', 'string'),
Field('filename', represent = lambda x, row: "None" if x == None else
x[:45]),
Field('up_file', 'upload', uploadseparate=True,
requires=IS_NOT_EMPTY()),
Field('up_date', 'datetime'),
Field('up_size', 'integer', represent= lambda x, row:
quikr_utils.sizeof_fmt(x) ),
Field('notes', 'text'))
Controller:
def submit():
import datetime
form = FORM(LABEL("File(s):"), INPUT(_name='up_files', _type='file',
_multiple=True,
requires=IS_UPLOAD_FILENAME(extension='txt|config|log')),INPUT(_type='submit'))
if form.accepts(request.vars, formname="form"):
response.flash = 'form accepted'
files = request.vars['up_files']
if not isinstance(files, list):
files = [files]
for f in files:
up_file = db.uploads.up_file.store(f, f.filename)
i = db.uploads.insert(notes=request.vars.notes,
up_file=up_file, filename=f.filename, up_date= datetime.datetime.now())
db.commit()
elif form.errors:
response.flash = 'form has errors'
else:
response.flash = 'please fill the form'
return dict(form=form)
