Hi folks,
How to read an uploaded file object line by line? This seemingly easy
task stumps me. Now I am totally lost. :-/
def restore():
form = SQLFORM.factory(Field
('backup','upload',requires=IS_UPLOAD_FILENAME()))
if form.accepts(request.vars,keepvalues=True,session=None):
# response.flash = type(form.vars.backup.file)
# It says it is an instance (of what?)
# response.flash = type(form.vars.backup.file.file)
# It says it is a file object. Good, but "file.file" is wired enough.
# response.flash = form.vars.backup.file.read()
# response.flash = form.vars.backup.file.file.read()
# The above two lines all return an empty string, ALWAYS.
response.flash = [l for l in form.vars.backup.file.file]
# And the above line does not read any data either.
# Please help.
# Actually I gonna use import_from_csv_file() for a restore.
# But now the import_from_csv_file() can not detect any data.
return form
# Thanks in advance!
