I'm creating a program that pings a host, in a list I'm storing the results of the ping and I want to publish the result in my template but it does not show me anything and I do not know what I'm doing wrong, I hope you can help me
the code is as follows
views.py
def ping(request):
errors = []
line = []
if 'ip1' in request.GET:
ip1=request.GET['ip1']
if not ip1:
if 'ip2' in request.GET:
ip2=request.GET['ip2']
if not ip2:
errors.append('Por favor introduce una IP.')
return render(request, 'ping.html', {'errors':errors})
else:
tre=tracert(ip2)
res1= "%s Host Traces" % ip2
return render(request, 'ping.html', {'res1':res1})
else:
return render(request, 'ping.html', {'errors':errors})
else:
response = os.system("ping -c 1 " + ip1 + " > /dev/null 2>&1")
if response == 0:
res= "%s Esta En Linea" % ip1
os.system("gnome-terminal -e 'bash -c \"ping -c 4 " +ip1+"; exec bash\"'")
pin=os.popen('ping -c 4 '+ip1,"r")
while True:
lines=pin.readline()
if not lines:
break
line.append(lines)
return render(request, 'ping.html', {'res':res}, {'line':line})
else:
res= "%s No Esta En Linea" % ip1
return render(request, 'ping.html', {'res':res})
else:
return render(request, 'ping.html', {'errors':errors})
def tracert(ip2):
ip2t=ip2
os.system("gnome-terminal -e 'bash -c \"traceroute " +ip2t+"; exec bash\"'")
in the lisa line I store the results when I print the list it shows me that it was stored correctly and then the return but at the moment of publishing in the Template it does not show me anything attached to the Template

This is my HTML code I want to show the data in a TEXTAREA but it does not show me anything I hope you can help me since I tried in many ways and I have not managed to show this information
Summary
In case my explanation was not clear, with pin=os.popen('ping -c 4 '+ip1,"r") , I ping a host that the user enters, I cycle to store the results in a list
while True:
lines=pin.readline()
if not lines:
break
line.append(lines)
Now I return the line list to the return render(request, 'ping.html', {'res':res}, {'line':line}) template
But when I show the line list in the template it does not show me anything the code I'm using is
{% if line%}
{% for i in line %}
<TEXTAREA rows="5" cols="30" name="txtsugerencias">{{i}}</TEXTAREA><BR>
{% endfor %}
{% endif %}
