Celery publisher doesn't send messages to the intended rabbitmq queue - rabbitmq

Question

I have a flask app running with celery in it. When a user inputs a message into app uri it needed to be sent to a rabbitmq queue as a message to a given queue. But it send messages to a default queue. How do I specifically send a message to a defined queue?
publisher.py
from flask import Flask,request,jsonify
from celery import Celery,bootsteps
from time import sleep
from kombu.common import QoS
class NoChannelGlobalQoS(bootsteps.StartStopStep):
requires = {'celery.worker.consumer.tasks:Tasks'}
def start(self, c):
qos_global = False
c.connection.default_channel.basic_qos(0, c.initial_prefetch_count, qos_global)
def set_prefetch_count(prefetch_count):
return c.task_consumer.qos(
prefetch_count=prefetch_count,
apply_global=qos_global,
)
c.qos = QoS(set_prefetch_count, c.initial_prefetch_count)
server = Flask(__name__)
broker_uri1="amqp://"
backend="mongodb+srv://"
app = Celery('TestApp', broker_uri=broker_uri1,backend=backend)
CELERY_TASK_ROUTES = {'app.tasks.*': {'queue': 'rabbit'},'app.task.*': {'queue': 'rabbit'}}
app.config_from_object('celeryconfig')
app.conf.task_default_exchange='rabbit'
app.conf.task_default_routing_key='rabbit'
app.steps['worker'].add(NoChannelGlobalQoS)
#server.route("/")
def print_hello():
return "Flask server working"
#server.route("/sync-reverse")
def reverse_by_worker_with_results():
input = request.args.get("text")
app.select_queues(queues="rabbit")
task = app.signature('tasks.reverse', kwargs={'text': input})
result = task.delay()
while result.status == 'PENDING':
print(result.status)
sleep(2)
print(result.status)
return "Reversed >><br />Input Text : " + input + "<br />Output Text : " + result.get()
#server.route("/async-reverse")
def reverse_by_worker():
input = request.args.get("text")
app.select_queues(queues="rabbit") #supposed to add queues to the task
task = app.signature('tasks.reverse', kwargs={'text': input})
result = task.delay()
if result.id:
return 'Task add'
else:
return 'Failure in adding task'
# Press the green button in the gutter to run the script.
if __name__ == '__main__':
server.run(host= '0.0.0.0')
worker.py
from celery import Celery,bootsteps
from time import sleep
from kombu.common import QoS
broker_uri='amqp:///'
backend_uri="mongodb+srv://"
app = Celery('TestApp', broker=broker_uri, backend=backend_uri)
app.config_from_object('celeryconfig')
app.conf.task_default_exchange='rabbit'
app.conf.task_default_routing_key='rabbit'
class NoChannelGlobalQoS(bootsteps.StartStopStep):
requires = {'celery.worker.consumer.tasks:Tasks'}
def start(self, c):
qos_global = False
c.connection.default_channel.basic_qos(0, c.initial_prefetch_count, qos_global)
def set_prefetch_count(prefetch_count):
return c.task_consumer.qos(
prefetch_count=prefetch_count,
apply_global=qos_global,
)
c.qos = QoS(set_prefetch_count, c.initial_prefetch_count)
app.steps['consumer'].add(NoChannelGlobalQoS)
#app.task
def reverse(text):
sleep(10)
return text[:-1]
I have used a celery config file to define the queue name and type as suggested
from kombu import Queue
task_queues = [Queue(name="rabbit", queue_arguments={"x-queue-type": "quorum"})]
task_routes = {
'tasks.add': 'rabbit',
}
