For one of my Ember.js apps, I have a bit of a too complex Form flow. While I’m working on simplifying frontend, I wanted a way to easily log validation errors that users received. In addition to debugging, this helps me improve the labels and instructions on the form itself.<\/p>\n\n\n\n

Backend in this case if Django Request Framework driven with JSON API. The idea is to log all validation errors and redirect them to Sentry in Debug mode:<\/p>\n\n\n\n

First we declare a custom DRF Exception handler the uses JSON API exception handler and copies the data to sentry:<\/p>\n\n\n\n

\/\/ exceptions.py\nfrom rest_framework_json_api.exceptions import exception_handler\nfrom raven.contrib.django.raven_compat.models import client\n\nfrom app.serializers import SubmissionSerializer\n\ndef custom_drf_exception_handler(exc, context):\n    response = exception_handler(exc, context)\n\n    if isinstance(context.get('view').get_serializer_class(), SubmissionSerializer):\n        client.captureMessage('Form Submission Validation Error', level='debug', extra=exc.get_full_details())\n\n\n    return response<\/code><\/pre>\n\n\n\n
And we also have to configure DRF to re-route errors through it:<\/p>\n\n\n\n
\/\/ settings.py\nREST_FRAMEWORK = {\n\t..\n\t'EXCEPTION_HANDLER': 'app.exceptions.custom_drf_exception_handler',\n\t..\n}<\/code><\/pre>\n\n\n\n
And that’s it. The end result is that when serialization error is triggered, we now get a nice error log in Sentry:<\/p>\n\n\n\n
