2025-12-22Refs #27100 -- Removed obsolete message from tutorial and migrations topic.Jacob Walls
The project state is cached, so when it was calculated in #27100 during the pre-migrate stage, it was no longer calculated on forward migrations. Backward migrations still calculate it.
2025-08-25Refs #36485 -- Rewrapped docs to 79 columns line length.David Smith
Lines in the docs files were manually adjusted to conform to the 79 columns limit per line (plus newline), improving readability and consistency across the content.
2025-08-25Refs #36485 -- Removed unnecessary parentheses in :meth: and :func: roles in ↵David Smith

2025-01-22Fixed #24529 -- Allowed double squashing of migrations.Georgi Yanchev
Co-authored-by: Raphael Gaschignard <raphael@rtpg.co>
2024-05-22Removed versionadded/changed annotations for 5.0.Natalia
This also removes remaining versionadded/changed annotations for older versions.
2024-04-26Made confirmation prompt in squashmigrations consistent with other prompts.Cole D
Prior to this change, squashmigrations would use a [yN] prompt to ask for user confirmation. A slash was added between the yes/no options to make it consistent with other commands that print similar prompts.
2024-01-17Fixed #31700 -- Made makemigrations command display meaningful symbols for ↵Amir Karimi
each operation.
2023-12-20Fixed #35015 -- Updated MySQL notes in migrations topic.Nicolas Lupien
2023-09-18Removed versionadded/changed annotations for 4.2.Mariusz Felisiak
This also removes remaining versionadded/changed annotations for older versions.
2023-09-13Fixed #34822 -- Added support for serializing functions decorated with ↵Nick Pope
functools.lru_cache in migrations. `@functools.cache` and `@functools.lru_cache` return an object of type `functools._lru_cache_wrapper` which prevented the migrations serializer from working. Simply using the existing `FunctionTypeSerializer` for this additional type works as expected.
2023-09-13Refs #34822 -- Added tests for serializing decorated functions in migrations.Nick Pope
Functions decorated with a decorator that is properly wrapped, e.g. by using `@functools.wraps`, are already supported.

2022-05-04Fixed #33675 -- Dropped support for PostgreSQL 10 and PostGIS 2.4.Mariusz Felisiak
2022-04-28Removed hyphen from pre-/re- prefixes.David
"prepopulate", "preload", and "preprocessing" are already in the spelling_wordlist. This also removes hyphen from double "e" combinations with "pre" and "re", e.g. preexisting, preempt, reestablish, or reenter.

2021-07-27Refs #32956 -- Changed "afterwards" to "afterward" in docs and comments.David Smith
This also removes unnecessary comments with the previous spelling. AP Stylebook has a short entry to advise the preferred spelling for "en-us". "Afterwards" is preferred in British English.
2021-05-29Fixed typos in comments and docs.David Sanders
2020-10-29Fixed #26962 -- Doc'd running migrations in transactions.Caio Ariede

2019-09-10Removed versionadded/changed annotations for 2.2.Mariusz Felisiak
2019-09-06Fixed #30573 -- Rephrased documentation to avoid words that minimise the ↵Tobias Kunze
involved difficulty. This patch does not remove all occurrences of the words in question. Rather, I went through all of the occurrences of the words listed below, and judged if they a) suggested the reader had some kind of knowledge/experience, and b) if they added anything of value (including tone of voice, etc). I left most of the words alone. I looked at the following words: - simply/simple - easy/easier/easiest - obvious - just - merely - straightforward - ridiculous Thanks to Carlton Gibson for guidance on how to approach this issue, and to Tim Bell for providing the idea. But the enormous lion's share of thanks go to Adam Johnson for his patient and helpful review.
2019-02-13Fixed #30184 -- Removed ellipsis characters from shell output strings.Dan Davis
Partially reverted 50b8493581fea3d7137dd8db33bac7008868d23a (refs #29654) to avoid a crash when the user shell doesn't support non-ASCII characters.
2019-01-28Refs #30033 -- Doc'd change regarding apps without migrations depending on ↵Tim Graham
