RuntimeError: There is no current event loop in thread 'django-main-thread'

Hi, I’m trying to integrate ib-insync with django using django-channels to get real time data from interactive brokers using a socket and using reqTickByTickData. But I’m struggling with the initial connection.

I wrote this line of code in services.py:

import json, nest_asyncio, asyncio
from ib_insync import *
ib = IB()
def connect_to_ib(): 
    print("Starting IB")
    ib_connection = ib.connect('127.0.0.1', 4002, clientId=1,timeout=4, readonly=False, account='')
    print("IB is Connected?", ib.isConnected())
    return ib_connection

but I’m getting this error:

RuntimeError: There is no current event loop in thread 'django-main-thread'

It worked in the past briefly and get an ib Object but I don’t know why It fails now.

I read #33 and #167 in order to solve this error but the problem persist.

def create_evenloop():
    print("Starting Event Loop")
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    nest_asyncio.apply()

Those functions were called in a consumer in django channels, (normally django is blocking but AsyncWebsocketConsumer from channels make non-blocking code inside PlotterConsumer class )

class PlotterConsumer(AsyncWebsocketConsumer):
    create_evenloop()
    ib = connect_to_ib()
    ...

no, I think goodboy has exaggerated the situation a bit in his response.

You can use ib_insync with any asyncio framework, but you should be careful to call async functions only, since all the sync-functions use the patching on the build-in python asyncio loop, which is obviously not working when you use non-native event loop. So, basic idea with any app which already has async-io capabilities - (1) start the app and it’s own event loop, (2) call all only “async def xxxAsync()” functions from ib_insync framework (from your app’s async functions)

The best place to look how it is done and ask additional questions is probably the ib-insync discussion group, which has plenty of posts on the subject https://groups.io/g/insync

@juan9222 was this ever resolved? I’m running into the same issue when trying to run my local server in django
