This commit adds support for filtering for topics in specific
subcategories via the categories filter query language.
For example: `category:documentation:admins` will filter for topics and
subcategory topics in
the category with slug "admins" whose parent category has the slug
"documentation".
The `=` prefix can also be used such that
`=category:documentation:admins` will exclude subcategory topics of the
category with slug "admins" whose parent category has the slug
"documentation".
If you happen to delete the general category before editing the welcome
topic, the banner will still display. This fix adds a after destroy hook
that will clear the entries for the welcome topic banner in the redis
cache.
Currently the auto-bump cooldown is hard-coded to 24 hours.
This change makes the highlighted 24 hours part configurable (defaulting to 24 hours), and the rest of the process remains the same.
This uses the new CategorySetting model associated with Category. We decided to add this because we want to move away from custom fields due to the lack of type casting and validations, but we want to keep the loading of these optional as they are not needed for almost all of the flows.
Category settings will be back-filled to all categories as part of this change, and creating a new category will now also create a category setting.
Original solution to use `description` instead of `text_description` was wrong: https://github.com/discourse/discourse/pull/20436
Problem is that we have to escape HTML tags.
However, we would like to use escape method which is keep `/` intact. Expected behavior is given by ERB::Util.html_escape instead of Rack::Utils.escape_html

The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
This is the first in a multi-part change to move the custom fields to a new table. It includes:
- Adding a new CategorySetting model and corresponding table.
- Populating it with data from the category_custom_fields table.
We recently had a bug which caused auto-bumping to "not work". The problem was that the value had been set to 0.5, which when coerced to an integer turned into 0. So the feature is "working as intended", but there's a possibility of misconfiguration.
When looking into this, I noticed that the inputs on the category settings page doesn't have any particular sanitisation in the front-end, and also one or two validations missing in the back-end.
This change:
- Takes an existing component, NumberField and enhances that by only allowing numeric input, essentially turning it into a managed input using the same approach as our PasswordField.
- Changes the numeric inputs on category settings page to use this component.
- Adds appropriate min constraints to the fields to disallow out-of-range values.
- Adds missing back-end validations to relevant fields.
When the `tags_listed_by_group` site setting is disable, we were seeing
the N+1 queries problem when multiple `CategoryTag` records are listed.
This commit fixes that by ensuring that we are not filtering through the
category `tags` association after the association has been eager loaded.
When EmbeddableHost is configured for a specific category and that category is deleted, then EmbeddableHost should be deleted as well.
In addition, migration was added to fix existing data.
When loading posts in a topic, the topic level guardian
checks are run multiple times even though all the posts belong to the
same topic. Profiling in production revealed that this accounted for a
significant amount of request time for a user that is not staff or anon.
Therefore, we're optimizing this by adding memoizing the topic level
calls in `PostGuardian`. Speficifally, the result of
`TopicGuardian#can_see_topic?` and `PostGuardian#can_create_post?`
method calls are memoized per topic.
Locally profiling shows a significant improvement for normal users
loading a topic with 100 posts.

* FIX: Use Category.secured(guardian) for hashtag datasource
Follow up to comments in #19219, changing the category
hashtag datasource to use Category.secured(guardian) instead
of Site.new(guardian).categories here since the latter does
more work for not much benefit, and the query time is the
same. Also eliminates some Hash -> Model back and forth
busywork. Add some more specs too.
* FIX: Server-side hashtag lookup cooking user loading
When we were using the PrettyText.options.currentUser
and parsing back and forth with JSON for the hashtag
lookups server-side, we had a bug where the user's
secure categories were not loaded since we never actually
loaded a User model from the database, only parsed it
from JSON.
This commit fixes the issue by instead using the
PretyText.options.userId and looking up the user directly
from the database when calling hashtag_lookup via the
PrettyText::Helpers code when cooking server-side. Added
the missing spec to check for this as well.
This commit automatically ensures that category channels
have slugs when they are created or updated based on the
channel name, category name, or existing slug. The behaviour
has been copied from the Category model.
We also include a backfill here with a simplified version
of Slug.for with deduplication to fill the slugs for already
created Category chat channels.
The channel slug is also now used for chat notifications,
and for the UI and navigation for chat. `slugifyChannel`
is still used, but now does the following fallback:
* Uses channel.slug if it is present
* Uses channel.escapedTitle if it is present
* Uses channel.title if it is present
In future we may want to remove this altogether
and always rely on the slug being present, but this
is currently not possible because we are not generating
slugs for DM channels at this point.
* FIX: Reset related site settings on general category delete
If the new seeded General category is deleted we also need to delete the
corresponding site setting for it so that we don't try and reference it.
This fixes a bug in the category dropdown composer.
This change creates the `clear_related_site_settings` after destroy
hook that could also be used by other features in the future, like maybe
when we have a `default_category_id` site_setting.
Looks like if `nil` out a site setting it is set to `0`?
```
[9] pry(main)> SiteSetting.general_category_id = nil
SiteSetting Load (0.4ms) SELECT "site_settings".* FROM "site_settings" WHERE "site_settings"."name" = 'general_category_id' LIMIT 1
=> nil
[10] pry(main)> SiteSetting.general_category_id
=> 0
```
That is why the tests check if the value is `< 1` and not `nil`.
* Use -1 instead of nil because it is the default
Adds a new upload field for a second dark mode category logo.
This alternative will be used when the browser is in dark mode (similar to the global site setting for a dark logo).
This table holds associations between uploads and other models. This can be used to prevent removing uploads that are still in use.

Previously we only supported a single 'required tag group' for a category. This commit allows admins to specify multiple required tag groups, each with their own minimum tag count.
A new category_required_tag_groups database table replaces the existing columns on the categories table. Data is automatically migrated.
Tags (and tag groups) can be configured so that they can only be used in specific categories and (optionally) restrict topics in these categories to be able to add/use only these tags. These restrictions work as expected when a topic is created without going through the review queue; however, if the topic has to be reviewed by a moderator then these restrictions currently aren't checked before the topic is sent to the review queue, but they're checked later when a moderator tries to approve the topic. This is because if a user manages to submit a topic that doesn't meet the restrictions, moderators won't be able to approve and it'll be stuck in the review queue.
This PR prevents topics that don't meet the tags requirements from being sent to the review queue and shows the poster an error message that indicates which tags that cannot be used.

* FIX: Don't accept accents in slug if generation_method == 'ascii'
Fixes bug reported in:
- https://meta.discourse.org/t/404-when-trying-to-edit-category-with-accent-in-slug/214762
- https://meta.discourse.org/t/formatting-and-accents-in-urls/215734/5
Assuming `SiteSetting.slug_generation_method == 'ascii'.
If the user provides a slug containing non-ascii characters while
creating the category, the user will receive a 404 error just
after saving the category since the slug will be escaped anyway but
Category.find_by_slug_path won't escape the category slug
causing the Edit Page of the category to be inaccessible.
This commit checks the provided slug and raises an error if the
provided slugcontains non-ascii characters ensuring that the
provided value is consistent with the site settings.
It also changes Category.find_by_slug_path to always escape the slug,
since if present, it is escaped anyway in Category.ensure_slug to
prevent the 404 in the Edit Category Page in case the user already
have some category with a non-ascii slug.
* Removed trailing whitespace
Sometimes administrators want to permanently delete posts and topics
from the database. To make sure that this is done for a good reasons,
administrators can do this only after one minute has passed since the
post was deleted or immediately if another administrator does it.
* FEATURE: Return subcategories on categories endpoint
When using the API subcategories will now be returned nested inside of
each category response under the `subcategory_list` param. We already
return all the subcategory ids under the `subcategory_ids` param, but
you then would have to make multiple separate API calls to fetch each of
those subcategories. This way you can get **ALL** of the categories
along with their subcategories in a single API response.
The UI will not be affected by this change because you need to pass in
the `include_subcategories=true` param in order for subcategories to be
returned.
In a follow up PR I'll add the API scoping for fetching categories so
that a readonly API key can be used for the `/categories.json` endpoint. This
endpoint should be used instead of the `/site.json` endpoint for
fetching a sites categories and subcategories.
* Update PR based on feedback
- Have spec check for specific subcategory
- Move comparison check out of loop
- Only populate subcategory list if option present
- Remove empty array initialization
- Update api spec to allow null response
* More PR updates based on feedback
- Use a category serializer for the subcategory_list
- Don't include the subcategory_list param if empty
- For the spec check for the subcategory by id
- Fix spec to account for param not present when empty
After deleting a category, we should soft-delete the category definition topic instead of hard deleting it. Else it causes issues while doing the user merge action if the source user has an orphan post that belongs to the deleted topic.
When configured, all topics in the category inherits the slow mode
duration from the category's default.
Note that currently there is no way to remove the slow mode from the
topics once it has been set.
Profiling showed that we were roughly 10% of a request time creating all
the ActiveRecord objects for categories in the `Site` model on a site with 61 categories.
Instead of querying for the categories each time based on which categories the user can see,
we can just preload all of the categories upfront and filter out the
categories that the user can not see.
This PR adds a new category setting which is a column in the `categories` table, `allow_unlimited_owner_edits_on_first_post`.
What this does is:
* Inside the `can_edit_post?` method of `PostGuardian`, if the current user editing a post is the owner of the post, it is the first post, and the topic's category has `allow_unlimited_owner_edits_on_first_post`, then we bypass the check for `LimitedEdit#edit_time_limit_expired?` on that post.
* Also, similar to wiki topics, in `PostActionNotifier#after_create_post_revision` we send a notification to all users watching a topic when the OP is edited in a topic with the category setting `allow_unlimited_owner_edits_on_first_post` enabled.
This is useful for forums where there is a Marketplace or similar category, where topics are created and then updated indefinitely by the OP rather than the OP making new topics or additional replies. In a way this acts similar to a wiki that only one person can edit.
On category create an exception will be thrown on this job because the
save transaction hasn't completed yet and the job cannot find the
category id. To prevent this we can use the rails 6 `after_save_commit`
hook that will fire after the category save transaction has finished for
both update and create actions.
DEV: Replace instances of Discourse.base_uri with Discourse.base_path
This is clearer because the base_uri is actually just a path prefix. This continues the work started in 555f467.
Previously, moving a category into another one, that already had a child category of that name (but with a non-conflicting slug) would cause a 500 error:
```
# PG::UniqueViolation:
# ERROR: duplicate key value violates unique constraint "unique_index_categories_on_name"
# DETAIL: Key (COALESCE(parent_category_id, '-1'::integer), name)=(5662, Amazing Category 0) already exists.
```
It now returns 422, and shows the same message as when you're renaming a category: "Category Name has already been taken".
