Question

我正在尝试在Django中进行ZeroMQ PUSH-PULL事件管理。基于this link，我将创建一个PUSH客户端：

context = zmq.Context()
zmq_socket = context.socket(zmq.PUSH)
zmq_socket.connect("tcp://127.0.0.1:5557")
for num in xrange(20000):
    work_message = { 'num' : num }
    zmq_socket.send_json(work_message)

和PULL服务器：

context = zmq.Context()
consumer_receiver = context.socket(zmq.PULL)
consumer_receiver.bind("tcp://127.0.0.1:5557")
work = consumer_receiver.recv_json()
data = work['num']
print data

在单独的文件中实现PUSH / PULL工作正常。但我想在Django视图中使用PULL服务器功能。也就是说，每当收到消息时，我希望它能在Django上接收，我可以操作Django ORM。我该如何处理？谢谢。

不确定您是否询问如何在使用ZMQ的脚本中包含Django，但这是我如何做到的（使用virtualenv）

#!/usr/bin/python2.7
import sys
import os

PATH=os.path.abspath(os.path.dirname(__file__))

# Relative path to the virtual environment
# (relative to the stand-alone script)
rel_path = '../../bin/activate_this.py'
activate_this = os.path.join(PATH, rel_path)
# this is needed to read the settings:
sys.path.append("../")
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mainapp.settings")
execfile(activate_this, dict(__file__=activate_this))

import zmq
import json
from django.conf import settings
import django
django.setup()
from .models import Mymodel

port = "5556"
context = zmq.Context()
print "Connecting to server..."
socket = context.socket(zmq.REQ)
socket.connect ("tcp://localhost:%s" % port)

while True:
    #this will listen and wait for a message 
    mymessage = json.loads(socket.recv())

    try:
        #do stuff
        my = Mymodel.objects.get(id=mymessage['id']) 

        #send something back 
        socket.send("1")               
    except:
        #on error
        socket.send("0")
