2025-08-14Fixed #36410 -- Added support for Template Partials to the Django Template ↵farhan
Language. Introduced `{% partialdef %}` and `{% partial %}` template tags to define and render reusable named fragments within a template file. Partials can also be accessed using the `template_name#partial_name` syntax via `get_template()`, `render()`, `{% include %}`, and other template-loading tools. Adjusted `get_template()` behavior to support partial resolution, with appropriate error handling for invalid names and edge cases. Introduced `PartialTemplate` to encapsulate partial rendering behavior. Includes tests and internal refactors to support partial context binding, exception reporting, and tag validation.

2025-07-23Refs #36500 -- Shortened some long docstrings and comments.Mike Edmunds
Manually reformatted some long docstrings and comments that would be damaged by the to-be-applied autofixer script, in cases where editorial judgment seemed necessary for style or wording changes.

2022-02-23Fixed #33532 -- Optimized CaseInsensitiveMapping instantiation for dicts.Keryn Knight
Internal usages of this class (e.g. HttpHeaders) provide it with a dict, so testing for that type first avoids the cost of going through the potential __instancecheck__ + _abc_instancecheck to establish it's a Mapping. Co-authored-by: Nick Pope <nick@nickpope.me.uk>
2022-02-07Refs #33476 -- Reformatted code with Black.django-bot
2021-09-22Optimized handling case-insensitive mappings.Illia Volochii
Elements yielded by _destruct_iterable_mapping_values are always unpacked. Since unpacking can be done with any iterable, there is no need to convert elements to tuples. Also, such elements can be used directly in for loops, creating a dictionary of them is excessive. Co-authored-by: Nick Pope <nick@nickpope.me.uk>

2020-10-30Updated MultiValueDict.update() to mirror dict.update() behavior.Nick Pope
Changes in behavior include: - Accepting iteration over empty sequences, updating nothing. - Accepting iterable of 2-tuples providing key-value pairs. - Failing with the same or comparable exceptions for invalid input. Notably this replaces the previous attempt to catch TypeError which was unreachable as the call to .items() resulted in AttributeError on non-dict objects.
2020-10-30Removed unused custom exception support for ImmutableList.Nick Pope
If the warning provided was an instance of Exception, then it would be used as-is. In practice this is untested, unused and ImmutableList is an undocumented internal datastructure.

2014-10-16Fixed #23664 -- Provided a consistent definition for OrderedSet.__bool__Thomas Chaumeny
This also defines QuerySet.__bool__ for consistency though this should not have any consequence as bool(qs) used to fallback on QuerySet.__len__ in Py3.
2014-09-05Revert "Fixed #23384 -- Allowed overriding part of a dictionary-type setting"Claude Paroz
This reverts commit 66757fee7e921ad4c35e0b3f80c25e026100b31c. Discussions have led to think that this functionality does not bring significant benefits to justify the added complexity. Read also discussions on ticket #22734.
