Re: steps to connect as client to a tcp/ip server

Hi Chiara

The best solution is make two different projects

one is your socket server and the other is the Django project.

is not a good idea connect with socket directly to Django, this will be cause some large delays and in case of connection fails?

what is the timeout of the socket connection?

is the same of dingo app?

The solutions will be, for example

django

celery

socket server

django is independently and the models are updated from celery workers

http://www.celeryproject.org/

this is the link of celery, is not so much easy but you can send some emails in this group and i'm sure that someone is ready to help you

have a nice day

Hi there, I'm a really newbye, I've followed the polls tutorial.

 I'm looking for a way to dinamically create web-pages that will send and receive message to a TCP/Ip server that use a custom protocol for communication.

I've got the python code that handle the communication and I kindly ask you some advice on the right way to do it:

1)create a model with the fields of data to be sent and received from server

2)create in the view: 1) function that handle the connection

                                 2) function that send data

                                 3) function that receive data

3) create a template with model's fields

Is this right?

Below the python code that is now standalone and working to connect to server.

#Socket client in python

import socket   #for sockets

import sys  #for exit

#create an INET, STREAMing socket

try:

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

except socket.error:

    print 'Failed to create socket'

    sys.exit()

print 'Socket Created'

host = '192.168.1.1';

port = 35000;

try:

    remote_ip = socket.gethostbyname( host )

except socket.gaierror:

    #could not resolve

    print 'Hostname could not be resolved. Exiting'

    sys.exit()

#Connect to remote server

s.connect((remote_ip , port))

print 'Socket Connected to ' + host + ' on ip ' + remote_ip

## SEND DATA

message = "GET / HTTP/1.1\r\n\r\n"

try :

    #Set the whole string

    s.sendall(message)

except socket.error:

    #Send failed

    print 'Send failed'

    sys.exit()

print 'Message send successfully'

#RECEIVE DATA

reply = s.recv(4096)

print reply

s.close()

Please let me know about it. Thanks. BR.
