drf-standardized-errors 0.12.5

Standardize your API error responses.

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",
      "detail": "This field is required.",
      "attr": "name"
    },
    {
      "code": "max_length",
      "detail": "Ensure this value has at most 100 characters.",
      "attr": "title"
    }
  ]
}

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

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

Features

• Highly customizable: gives you flexibility to define your own standardized error responses and override specific aspects the exception handling process without having to rewrite everything.
• 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 drf-standardized-errors

Add drf-standardized-errors to your installed apps

INSTALLED_APPS = [
    # other apps
    "drf_standardized_errors",
]

Register the exception handler

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

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 = {"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.
