Replace Bare except Clauses with Specific Exception Handling in Analytics Views #4890
Description
Description
The file apps/analytics/views.py contains bare except clauses that catch all exceptions, which is considered a bad practice as it can:
- Hide unexpected errors and bugs
- Make debugging more difficult
- Catch exceptions that shouldn't be silently handled (e.g.,
KeyboardInterrupt,SystemExit)
Current Implementation
Line 173:
try:
serializer = ChallengePhaseSubmissionCountSerializer(
challenge_phase_submission_count
)
response_data = serializer.data
return Response(response_data, status=status.HTTP_200_OK)
except: # noqa: E722
response_data = {"error": "Bad request. Please try again later!"}
return Response(response_data, status=status.HTTP_400_BAD_REQUEST)Line 270:
try:
serializer = LastSubmissionTimestampSerializer(
last_submission_timestamp
)
response_data = serializer.data
return Response(response_data, status=status.HTTP_200_OK)
except: # noqa: E722
response_data = {"error": "Bad request. Please try again later!"}
return Response(response_data, status=status.HTTP_400_BAD_REQUEST)Proposed Fix
Replace the bare except clauses with specific exception handling and add proper logging:
import logging
logger = logging.getLogger(__name__)
# Example fix for line 173:
try:
serializer = ChallengePhaseSubmissionCountSerializer(
challenge_phase_submission_count
)
response_data = serializer.data
return Response(response_data, status=status.HTTP_200_OK)
except (TypeError, ValueError, AttributeError) as e:
logger.error(
"Error serializing challenge phase submission count: %s", str(e)
)
response_data = {"error": "Bad request. Please try again later!"}
return Response(response_data, status=status.HTTP_400_BAD_REQUEST)Benefits
- Follows Python best practices (PEP 8)
- Improves debuggability by logging specific exceptions
- Removes
# noqa: E722suppression comments - Makes error handling more explicit and maintainable
