DRF Standardized Errors

Standardize your DRF API error responses.

By default, the package will convert all API error responses (4xx and 5xx) to a standardized format:

{
  "type": "validation_error",
  "errors": [
    {
      "code": "required",
      "message": "This field is required.",
      "field": "name"
    },
    {
      "code": "max_length",
      "message": "Ensure this value has at most 100 characters.",
      "field": "title"
    }
  ]
}

{
  "type": "client_error",
  "errors": [
    {
      "code": "authentication_failed",
      "message": "Incorrect authentication credentials.",
      "field": null
    }
  ]
}

{
  "type": "server_error",
  "errors": [
    {
      "code": "error",
      "message": "A server error occurred.",
      "field": null
    }
  ]
}

Features

• Supports nested serializers and ListSerializer errors
• Plays nicely with error monitoring tools (like Sentry, ...)

Requirements

• python >= 3.8
• Django >= 3.2
• DRF >= 3.12

Quickstart

Install with pip

pip install elefanto-drf-exceptions

Add drf-standardized-errors to your installed apps

INSTALLED_APPS = [
    # other apps
    "elefanto_drf_exceptions",
]

Register the exception handler

REST_FRAMEWORK = {
    # other settings
    "EXCEPTION_HANDLER": "elefanto_drf_exceptions.handler.exception_handler"
}

Register the error formatter

DRF_STANDARDIZED_ERRORS = {
    "EXCEPTION_FORMATTER_CLASS": "elefanto_drf_exceptions.formatter.ElefantoExceptionFormatter",
}

Notes

Standardized error responses when DEBUG=True for unhandled exceptions are disabled by default. That is to allow you to get more information out of the traceback. You can enable standardized errors instead with:

DRF_STANDARDIZED_ERRORS = {
    # other settings
    "ENABLE_IN_DEBUG_FOR_UNHANDLED_EXCEPTIONS": True
}

Integration with DRF spectacular

If you plan to use drf-spectacular to generate an OpenAPI 3 schema, install with pip install drf-standardized-errors[openapi]. After that, check the doc page for configuring the integration.
