Unlike other models, notes had a special rule where if you deleted or
undeleted a note, it would always create a new version instead of
merging it into the previous version. Remove this rule since it didn't
have a purpose and it was inconsistent with other versioned models.
Track the history of the tag `category` and `is_deprecated` fields in
the `tag_versions` table.
Adds generic Versionable and VersionFor concerns that encapsulate most
of the history tracking logic. These concerns are designed to make it
easy to add history to any model.
There are a couple notable differences between tag versions and other versions:
* There is no 1 hour edit merge window. All changes to the `category`
and `is_deprecated` fields produce a new version in the tag history.
* New versions aren't created when a tag is created. Versions are only
created when a tag is edited for the first time. The tag's initial
version isn't created until *after* the tag is edited for the first time.
For example, if you change the category of a tag that was last updated
10 years ago, that will create an initial version of the tag backdated
to 10 years ago, plus a new version for your edit.
This is for a few reasons:
* So that we don't have to create new tag versions every time a new tag
is created. This would be wasteful because most tags never have their
category or deprecation status change.
* So that if you make a typo tag, your name isn't recorded in the tag's
history forever.
* So that we can create new tags in various places without having to know
who created the tag (which may be unknown if the current user isn't set).
* Because we don't know the full history of most tags, so we have to
deal with incomplete histories anyway.
This has a few important consequences:
* Most tags won't have any tag versions. They only gain tag versions if
they're edited.
* You can't track /tag_versions to see newly created tags. It only
shows changes to already existing tags.
* Tag version IDs won't be in strict chronological order. Higher IDs may
have created_at timestamps before lower IDs. For example, if you
change the category of a tag that is 10 years old, that will create an
initial version with a high ID, but with a created_at timestamp dated
to 10 years ago.
Fixes#4402: Track tag category changes
Fixup for 015c6dc7d. Show a warning about failure to add a tag instead
of raising an exception when trying to tag a post with `char:copy:foo`.
This tries to create a tag named `copy:foo` then set the category to
character, which doesn't work because `copy:foo` isn't a valid tag name.
Drop the ability to write e.g. `create alias foo -> char:bar` in a BUR
to change the tag's type as a side effect. You can only use these
tag type prefixes in tag edits now.
This feature was only intended to be used in tag edits. The fact it
worked elsewhere was unintended behavior.
This feature was problematic because it relied on `Tag.find_or_create_by_name`
automagically changing the tag's category when the tag name contained a
tag category prefix, e.g. `char:hatsune_miku`. This meant that merely
looking up a tag could have the side effect of changing its category.
It was also bad because `find_or_create_by_name` had a hidden dependency
on the current user, which may not be set or available in all contexts.
Fix a bug where the word `lazy` wasn't highlighted in `don't_say_"lazy"`
when searching for `lazy`. The bug was that punctuation surrounding
words wasn't properly split from the word.
Switch autocomplete to match individual words in the tag, instead of
only matching the start of the tag.
For example, "hair" matches any tag containing the word "hair", not just tags
starting with "hair". "long_hair" matches all tags containing the words "long"
and "hair", which includes "very_long_hair" and "absurdly_long_hair".
Words can be in any order and words can be left out. So "closed_eye" matches
"one_eye_closed". "asuka_langley_souryuu" matches "souryuu_asuka_langley".
This has several advantages:
* You can search characters by first name. For example, "miku" matches "hatsune_miku".
"zelda" matches both "princess_zelda" and "the_legend_of_zelda".
* You can find the right tag even if you get the word order wrong, or forget a word.
For example, "eyes_closed" matches "closed_eyes". "hair_over_eye" matches "hair_over_one_eye".
* You can find more related tags. For example, searching "skirt" shows all tags
containing the word "skirt", not just tags starting with "skirt".
The downside is this may break muscle memory by changing the autocomplete order of
some tags. This is an acceptable trade-off.
You can get the old behavior by writing a "*" at the end of the tag. For
example, searching "skirt*" gives the same results as before.
Add ability to search your unposted uploads using AI tags. Like with
media assets, only basic tags are supported (no metatags) and complex
multi-tag searches will probably be slow.
The default AI tag confidence threshold is 50%. There's a hidden
search[min_score] URL param that lets you change this.
Add ability to search the /media_assets index by AI tags. Multi-tag
searches are supported, including AND/OR/NOT operators, but metatags
aren't supported. Multi-tag searches will probably be slow.
The default AI tag confidence threshold is 50%. There's a hidden
search[min_score] URL param that lets you change this.
* Fix the suggested tags list in the related tags box not showing rating tags.
* Fix the suggested tags list showing tags that have been aliased to another tag.
Add a Suggested tags list to the Related Tags box. The suggested tags
are just the AI tags for the post.
Suggested tags are currently hidden in CSS for beta testing. Use custom
CSS to unhide them.
Allow searching for e.g. `ai:monochrome,0%` to find posts where the AI has 0% confidence
the post should be tagged monochrome.
This is useful for finding mistagged posts. You can search `monochrome ai:monochrome,0%`
to find posts that are potentially mistagged as monochrome, that is, posts that are
tagged monochrome but where the AI has 0% confidence that it should be tagged monochrome.
Not all cases will be mistags. The majority will be cases where the AI failed to identify
the tag. This is also useful for studying the AI's failures.
Fix a bug where `Post#has_tag?` would return false for tags that
contained colons. This caused the /ai_tags page to incorrectly say
certain tags weren't present on the post.
Add "Add" and "Remove" buttons beneath thumbnails on the /ai_tags page.
These let you add the tag to the post if it's correct, or remove it if
it's wrong.
Allow searching for e.g. `ai:solo,>=90%` to to find posts that have the
solo tag with >=90% confidence. The default confidence level is 50%. The
delimiter is a comma because it's one of the few characters not allowed
in tag names.
Add a database model for storing AI-predicted tags, and add a UI for browsing and searching these tags.
AI tags are generated by the Danbooru Autotagger (https://github.com/danbooru/autotagger). See that
repo for details about the model.
The database schema is `ai_tags (media_asset_id integer, tag_id integer, score smallint)`. This is
designed to be as space-efficient as possible, since in production we have over 300 million
AI-generated tags (6 million images and 50 tags per post). This amounts to over 10GB in size, plus
indexes.
You can search for AI tags using e.g. `ai:scenery`. You can do `ai:scenery -scenery` to find posts
where the scenery tag is potentially missing, or `scenery -ai:scenery` to find posts that are
potentially mistagged (or more likely where the AI missed the tag).
You can browse AI tags at https://danbooru.donmai.us/ai_tags. On this page you can filter by
confidence level. You can also search unposted media assets by AI tag.
To generate tags, use the `autotag` script from the Autotagger repo, something like this:
docker run --rm -v ~/danbooru/public/data/360x360:/images ghcr.io/danbooru/autotagger ./autotag -c -f /images | gzip > tags.csv.gz
To import tags, use the fix script in script/fixes/. Expect a Danbooru-size dataset to take
hours to days to generate tags, then 20-30 minutes to import. Currently this all has to be done by hand.
This is so admins can overrule flags and always have the final say in whether a
post is approved, even in the event of coordinated or sockpuppet flagging.
Fixes#4980: Way to mark flags as invalid for admins
Add a system for upgrading accounts using upgrade codes. Users purchase
an upgrade code off-site then redeem it on-site to upgrade their account
to Gold. Upgrade codes are randomly pre-generated and are one time use
only. Codes have enough randomness that guessing a code is infeasible.
* Add "general" rating.
* Rename "safe" rating to "sensitive".
* Change safe mode to include both rating:s and rating:g.
* Treat rating:safe as a synonym for rating:sensitive.
* Link "howto:rate" in the post edit form.
Refactor ratings to not be hardcoded in various places. Make it so
all ratings are defined in Post::RATINGS.
Also make it so that you can search multiple ratings at once with `rating:q,e`.
Sometimes uploads fail with this error:
Failed to replace upload_media_assets because one or more of the new
records could not be saved.
Change it so that media assets are saved individually, so that if saving
any of them fails we get a better error message.
* Remove the default list of blocked tags in safe mode.
* Change it so that tags that are blocked in safe mode are filtered out
at the database level rather than at the html level.
* Fix it so that if upgrades are disabled, only the payment button is disabled instead of the whole page.
* Fix it so that disabling upgrades with DANBOORU_USER_UPGRADES_ENABLED="false" works.
