Nick Pope e042024b28 Allowed custom formatting of lazy() objects.
This allows for formatting of lazy objects which have a custom formatter
defined by overriding the default implementation from `object`.

Nick Pope fd97b0471b Allowed multiplication of lazy() objects with int return type. 2023-06-12 05:59:40 +02:00
Ran Benita ae94077e7d Made proxy class in lazy() prepare eagerly.
Previously, the proxy class was prepared lazily:

  lazy_identity = lazy(identity, int)
  lazy_identity(10)  # prepared here
  lazy_identity(10)

This has a slight advantage that if the lazy doesn't end up getting
used, the preparation work is skipped, however that's not very likely.

Besides this laziness, it is also inconsistent in that the methods which
are wrapped directly (__str__ etc.) are prepared already when __proxy__
is defined, and there is a weird half-initialized state.

This change it so that everything is prepared already on the first line
of the example above.

Nick Pope e0e0204477 Added more tests for django.utils.functional.lazy(). 2023-06-12 05:29:30 +02:00
Ran Benita a57d5d9bbc Made bytes and str return types no longer mutually exclusive in lazy().
They are no longer special cased.

Ran Benita f5817c24f4 Refs #34445 -- Fixed string-casting of non-string lazy objects when value may be bytes.
If the result type is bytes, then calling bytes() on it does nothing.

If the result type is not bytes, we should not cast to bytes, just
because the return value may be bytes.

Ran Benita 066aabcb77 Fixed #34445 -- Fixed string-casting of non-string lazy objects.
This removes __text_cast() as it's the same as __cast().
_delegate_bytes and __delegate_text are mutually exclusive so the
`if self._delegate_bytes` branch in __cast() is unreachable.

Ran Benita a2c31e12da Fixed #30498 -- Fixed proxy class caching in lazy().
