Change grouping of an specific exception in sentry (django)

Question

I use raven with my django web application and i want to prevent an exception from excessive grouping as described in documentations here while preserving default behavior for other exceptions.
More concretely I have a code snippet like this somewhere in my app:

raise Exception('Nothing done for catalog #' + str(catalog_id))

in sentry i see exceptions for different catalogs grouped together because it rolls them up based on stack-traces. As i understood from docs i should use something like:

client.captureException(fingerprint=['{{ default }}', str(catalog_id)])

but i don't know where in my code it should be used.

Answer 1

client.captureException(fingerprint=['{{ default }}', str(catalog_id)]) is used inside of an except clause.

try:
    raise Exception('Nothing done for catalog #' + str(catalog_id))
except Exception:
    client.captureException(fingerprint=['{{ default }}', str(catalog_id)])
