Unable to add Panel to Django

[Solo_Leveling]

Hi
I have installed panel==0.11.3, Django==2.2, bokeh==2.3.2, channels==3.0.3.
I have done same as instructed in documentation Django Apps — Panel 0.11.3 documentation.

When I ran using python manage.py runserver, I got error CommandError: You have not set ASGI_APPLICATION, which is needed to run the server.

Then I added ASGI_APPLICATION = ‘panel_django.routing.application’ in settings.py.

When I ran the application again, I’m getting error:
File “<local file>\panelenv\lib\site-packages\asgiref\compatibility.py”, line 33, in new_application
instance = application(scope)
TypeError: init() takes 1 positional argument but 2 were given
HTTP GET /favicon.ico 500 [0.59, 127.0.0.1:55437]

It would we very helpful if someone could help me out of this issue.

Try to downgrade channels to 2.4.0.

Thank you for the solution @Hoxbro, that worked.

But, I got a new error:

@Solo_Leveling

See this discourse topic to see if it also addresses your errors, which look to be the same issue. The regression appears to have returned to panel 0.11.3, but the workaround still solves it.

Panel regression? (embedding panel in gunicorn+Flask)

The dev version installed via conda fixes the issue with the flask-embed example. For completeness, here’s the panel version info I see with the dev version. Type "help", "copyright", "credits" or "license" for more information. >>> import panel >>> panel.__version__ '0.11.0a6' >>>

WORKAROUND

from bokeh.settings import settings

settings.resources = 'inline'
