I have created a form that takes server ip, username and password. I use
pexpect to ssh into remote server, run a particular command and get basic
data related to that server. I am creating the form using controller and
also doing ssh in same controller and returning both form and processed
data from same controller. But, when I run the html it is not displaying
correct result, I am also confused on how I can load a table below add
button inside a same page but as different frame.
My Controller script as below:
# coding: utf8# try something likedef display():
import pexpect
import sys
import time
import cgi, cgitb
import getpass
import urllib3
import xml.etree.ElementTree as ET
import json
attr = ["Hostname", "Model Name", "Version", "connected count", "online
Count"]
form=FORM(DIV('server IP', INPUT(_name = 'ipaddr', requires =
IS_NOT_EMPTY()),
'Username', INPUT(_name = 'uname', requires =
IS_NOT_EMPTY()),
'Password',INPUT(_name = 'password', _type = 'password',
requires = IS_NOT_EMPTY()),
INPUT(_value='Add',_type='submit')))
valuelist = list()
if form.accepts(request,session):
response.flash = 'form accepted'
ssh_cmd = 'ssh'
username = request.vars['uname'].strip()
ip_addr = request.vars['ipaddr'].strip()
password = request.vars['password'].strip()
command = ssh_cmd+" "+username+"@"+ip_addr
try:
child = pexpect.spawn(command)
child.expect('(?i)password')
child.sendline(password)
child.expect('bash2.1# ')
child.sendline('show sys-summary general')
child.expect('bash2.1# ')
except Exception, e:
print e
print child.before
lines = child.before
for line in lines.split("\n"):
if any(word in line for word in attr):
keyValue = line.split(":", 1)
value = keyValue[1].strip()
valuelist.append(value)
sys.stdout.flush()
if child.isalive():
child.sendline('exit') # Try to ask ftp child to exit.
child.close()
if child.isalive():
print('Child did not exit gracefully.')
else:
print('Child exited gracefully.')
elif form.errors:
response.flash = 'form has errors'
else:
response.flash = 'please fill the form'
return dict(form=form, valuelist=valuelist)
Now my html code is as below. It is just simple and I want to test whether
that particular values has been received accordingly or not, hence I am
just calling returned value
View code is:
{{extend 'layout.html'}}<h2>Controller Page</h2>{{=form}}<h2>Submitted
variables</h2>{{=valuelist}}<h2>Accepted
variables</h2>{{=BEAUTIFY(form.vars)}}<h2>Errors in
form</h2>{{=BEAUTIFY(form.errors)}}
Could some one suggest, what change I can make so that I can see details of
server below add button itself ? Like
Server IP: Username: Password: add
222.222.222.222 examplehostname 333modelno 3.2 44 connected 22 online
Thanks !
