Question

可以告诉我如何在加载所有应用之前访问模型这是mqtt.py我在init.py初始化并访问的import paho.mqtt.client as mqtt from Transport.models import BusPosition # Broker CONNACK response def on_connect(client,userdata,flags,rc): print ("Connected with result code "+str(rc)) # Subcribing to topic and recoonect for client.subscribe("trackrkct") #Receive message def on_message(client,userdata,msg): print(msg.topic+" "+str(msg.payload)) BusPosition.create(1, "Mon, 23 May 2016 08:30:15 GMT", 11.0998, 77.9098) client = mqtt.Client() client.on_connect = on_connect client.on_message = on_message client.connect("broker.hivemq.com",1883,60) 模型

from kctsmarttransport import mqtt

mqtt.client.loop_start()

这是我初始化mqtt.py的init.py

models.py

这是我的from __future__ import unicode_literals from django.db import models class BusPosition(models.Model): bus = models.ForeignKey(Bus) time = models.DateTimeField lat = models.FloatField(max_length=20) lng = models.FloatField(max_length=20) @classmethod def create(cls,bus,time,lat,lng): busPosition = cls(bus=bus,time=time,lat=lat,lng=lng) busPosition.save() return busPosition

Process finished with exit code 1

我在应用尚未加载时收到了这些错误
