i follow this article :http://code.google.com/intl/en/appengine/docs/python/tools/uploadingdata.html

and want to download all data from my app ,

but when i use the next code,it show error:

D:\zjm_demo\app>appcfg.py --dump --app_id=zjm1126 --url=http://zjm1126.appspot.c
om/remote_api --filename=a.csv
Usage: appcfg.py [options] <action>

appcfg.py: error: no such option: --dump

why ?

thanks

updated

i use this :

appcfg.py download_data  --application=zjm1126 --url=http://zjm1126.appspot.com/remote_api --filename=a.csv

Answer 1

The documentation appears to be incorrect:

I found that I had to use download_data instead of –dump and –application instead of –app_id, for example:

appcfg.py download_data --application=app_id --url=http://etc --filename=file
