Utils - URI

smarter.common.utils.uri

Helpers for building absolute URIs from Django or DRF request objects.

This module provides the smarter_build_absolute_uri function, which attempts to construct an absolute URI from a given request object. It supports Django’s HttpRequest, Django REST Framework’s Request, and mock objects for testing. The function is robust to missing or malformed request data and returns a fallback test URL if the request cannot be resolved.

Example usage:

from smarter.common.utils import smarter_build_absolute_uri
from django.http import HttpRequest

request = HttpRequest()
request.META['HTTP_HOST'] = 'localhost:9357'
request.path = '/api/v1/resource/'
url = smarter_build_absolute_uri(request)
print(url)  # Output: http://localhost:9357/api/v1/resource/
smarter.common.utils.uri.smarter_build_absolute_uri(request)[source]

Attempts to construct the absolute URI for a given request object.

Parameters:

request (HttpRequest) – The request object, which may be an instance of django.http.HttpRequest, rest_framework.request.Request, django.core.handlers.wsgi.ASGIRequest, or a mock object for testing.

Returns:

The absolute URI as a string, or a fallback test URL if the request is invalid or cannot be resolved.

Return type:

Optional[str]

Note

  • If the request is a Django REST Framework Request, it is recast to a Django HttpRequest.

  • If the request is a mock object (e.g., from unit tests), a synthetic test URL is returned.

  • The function first tries to use Django’s build_absolute_uri method. If unavailable, it attempts to build the URL from scheme, host, and path attributes.

  • If all attempts fail, a generic fallback URL is returned.

Warning

If the request is None or cannot be resolved, the function logs a warning and returns a fallback test URL. Always validate the returned URL before using it in production.

Example usage:

from smarter.common.utils import smarter_build_absolute_uri
from django.http import HttpRequest

request = HttpRequest()
request.META['HTTP_HOST'] = 'localhost:9357'
request.path = '/api/v1/resource/'
url = smarter_build_absolute_uri(request)
print(url)  # Output: http://localhost:9357/api/v1/resource/

# Example with DRF Request
from rest_framework.request import Request
drf_request = Request(...)
url = smarter_build_absolute_uri(drf_request)
print(url)

# Example with None
url = smarter_build_absolute_uri(None)
print(url)  # Output: http://testserver/unknown/
