Title:
[Neutron][Improvement]Neutron can ask user to see the help file in
case the user passes wrong arguments in CLI
Status in python-neutronclient:
New
Bug description:
Openstack CLIs have the support of displaying help file for all components,
specifically neutron.
However, for a new user/developer, understanding the help file is important.
When we pass incorrect attributes to a nova client, we get the following
output:
##########################
reedip@reedip-VirtualBox:/opt/stack/sqlalchemy$ nova agent-delete
usage: nova agent-delete <id>
error: too few arguments
Try 'nova help agent-delete' for more information.
##########################
The last line gives a useful information to the new user/developer as to what
he/she can do to find out more information.
Something like this can be added to the neutron-client as well
Current output of neutron client:
##########################
reedip@reedip-VirtualBox:/opt/stack/sqlalchemy$ neutron firewall-create
usage: neutron firewall-create [-h] [-f {html,json,shell,table,value,yaml}]
[-c COLUMN] [--max-width <integer>]
[--prefix PREFIX] [--request-format {json,xml}]
[--tenant-id TENANT_ID] [--name NAME]
[--description DESCRIPTION] [--shared]
[--admin-state-down] [--router ROUTER]
POLICY
neutron firewall-create: error: too few arguments
##########################
Expected output:
##########################
reedip@reedip-VirtualBox:/opt/stack/sqlalchemy$ neutron firewall-create
usage: neutron firewall-create [-h] [-f {html,json,shell,table,value,yaml}]
[-c COLUMN] [--max-width <integer>]
[--prefix PREFIX] [--request-format {json,xml}]
[--tenant-id TENANT_ID] [--name NAME]
[--description DESCRIPTION] [--shared]
[--admin-state-down] [--router ROUTER]
POLICY
neutron firewall-create: error: too few arguments
Try 'neutron help firewall-delete' for more information.
