Disable Django Debugging for Celery

Is it possible to set DEBUG=False for only a specific app in Django? Celery has a known memory leak when debugging is enabled. I have a development server where I want Celery to run as a service, without debugging so it doesn't leak memory, but I want the rest of my Django app to use debugging so errors will be show开发者_Go百科n when testing.

Celery doesn't have a memory leak, it's how Django works:

When DEBUG is enabled Django appends every executed SQL statement to django.db.connection.queries, this will grow unbounded in a long running process environment.

I guess you could use a hack like:

if "celeryd" in sys.argv:
    DEBUG = False

The hack from @asksol didn't do it for me, I had to do

if "celery" in sys.argv[0]:
    DEBUG = False

Because sys.argv is something like ['/path/to/celery', 'worker', '-A', 'app']

Im using python 3.6 and celery 4

Building off of asksol's answer (https://stackoverflow.com/a/4806384/3009897) in light of sww314's comment on that answer, that the indicated method does not work in Celery 4.x, one can instead rely on the inspect module to determine the execution stack that the DEBUG setting is being accessed in.

For my purposes, the following change worked:

if DEBUG and 'celery' in inspect.stack()[-1][1]:
    DEBUG = False

This assumes that the outermost invocation frame will include the string 'celery' in the associated filepath. (The check for DEBUG is a stab at ensuring that if this is left in place for production (where DEBUG = False should be set), the inspect shouldn't take place.)
