I am facing some difficulty to integrate MQTT in Django ORM it showing error, I don't know how to solve the problem, So please help me. I am giving you the snippet of my code.

• mqtt.py

import paho.mqtt.client as mqtt
import json
import time
from django.conf import settings
#from .models import Emp

#from MQTT.views import get_detail

MQTT_DEFAULT_USER = '50000025'
MQTT_DEFAULT_PASSWORD = 'Test@1234'



def on_connect(client, userdata, flags, rc):
 print("on_connect")
 client.subscribe('sh/k',qos=1)
 

def on_message(client, userdata, message):
 print("This is on_message function !!!!")
 data=message.payload.decode()
 print(data)
 data=json.loads(data)
 print('-----------------------------')
 ret=get_detail(data)
 if message.payload:
 client.publish("s/us",ret) 
 print("...done...")

def on_log(client, userdata, level, buf): # this is call back function
 print("Logs :"+buf)

client = mqtt.Client('rahul')
client.username_pw_set(MQTT_DEFAULT_USER, MQTT_DEFAULT_PASSWORD )
client.on_message = on_message
client.on_connect = on_connect
client.on_log = on_log


client.connect('192.168.02.125', port=1883)

• view.py

from django.shortcuts import render
from .models import Emp
import json
 
def get_detail(data):
 
 data=Emp.objects.filter(name=data.name)[0]
 data=json.dumps(data)
 return data

• models.py

from django.db import models

class Emp(models.Model):
 name=models.CharField(max_length=50)
 address=models.CharField(max_length=50)
 salary=models.DecimalField(max_digits=10,decimal_places=2)

 class Meta:
 db_table='emp'

These are the file which is containing my Django project, I want to do the operation on that data which is provided an MQTT publisher client and send the data means publish one topic with the response data. how to do.

Hi,

I am using Django 3.1.1 and Python 3.7.

When I try to delete a topic, I get this Error:

TypeError at /admin/django_mqtt/topic/3/delete/

unhashable type: 'Topic'
Request Method: GET
Request URL: http://127.0.0.1:8000/admin/django_mqtt/topic/3/delete/
Django Version: 3.1.1
Exception Type: TypeError
Exception Value: unhashable type: 'Topic'

It would be great if you could provide a few clearer examples of how you use the MQTT connection in a Django app.

I'm specifically wanting to do the following two tasks but am unsure how:

• subscribe to a specific MQTT topic and keep a text field or many text fields in my HTML page up to date when new data comes in.
• publish data to a topic/various topics upon saving a form

Many thanks in advance.

Create test splited

On Mosquitto auth get the user from the settings

Create Dockerfile allowing create images with different python and django versions

I see this popular project uses the GPL license. Often in Python land I've learned this isn't always intentional, and sometimes a mistake.

Is your intention that any project that uses this library should be open sourced as GPL?
Basically, an commercial usage of this library in a private project is now forbidden and risks lawsuit.

If that wasn't your intention, could you please change the license to LGPL? (or BSD). Using the LGPL would still enforce authors to contribute any changes to this library, but no longer enforces any project that uses this library to become GPL too.

fixed!

Hi,

Could anyone give me a tip on getting setup? Do I need Linux to run this or is Windows 10 Ok?

I would like to try this but very new to MQTT and mostly newb to Django but I understand some of the steps and work flow.

How user for publish data con MQTT server ?
Is this all on the same machine? To run the MQTT broker through Django and also a client application?

Thank you for any help this seems like a cool project.

Mysql 5.6

I'm running Django 1.11.5 and would like to connect to a MQTT broker using your library. I see in the requirements.txt you've limited the Django version to v1.9.1. Is there a specific reason for this?

How to install it on Django?
