Hello
I have a following problem
When I try to serve a zip file to user i get the following error
Uncompressed size\nTypeError: object of type \'NoneType\' has no len()
There is data to be compressed, but there is lots of it so this I believe
is causing the problem
my code is the following:
def exportLssOut():
scriptId = request.args[0]
userId = auth.user_id
ExportConditionsCheck(userId)
query = db(db.scripts.id == scriptId).select(db.scripts.sc_engine_output,
db.scripts.sc_lls,
db.scripts.sc_menu_data, db.scripts.sc_errors).first()
engineOutData = query['sc_engine_output']
llsData = query['sc_lls']
jsonDb = query['sc_menu_data']
jsonErrors = query['sc_errors']
#
import zipfile, cStringIO
exported_chunks_zip = cStringIO.StringIO()
zipf = zipfile.ZipFile(exported_chunks_zip, "w",
compression=zipfile.ZIP_STORED )
zipf.writestr('%s_lls.txt' % str(scriptId), llsData)
zipf.writestr('%s_out.txt' % str(scriptId), engineOutData)
zipf.writestr('%s_json.txt' % str(scriptId), jsonDb)
zipf.writestr('%s_json_err.txt' % str(scriptId), jsonErrors)
zipf.close()
moment = datetime.datetime.now().strftime('%Y%m%dT%H%M%S')
response.headers['Content-Type']='multipart/x-zip'
response.headers['Content-Disposition']='attachment;
filename=ExportLLSOUT_%s.zip'% (moment)
#formatedDateTime = '%s%s%sT%s%s%s' % (dateTimeNow.year, dateTimeNow.month,
dateTimeNow.day ,dateTimeNow.hour,dateTimeNow.minute,dateTimeNow.second )
return exported_chunks_zip.getvalue()
any suggestions?
thank you
