Ignored columns can only be dropped when its associated post-deploy
migration has been promoted to a regular migration. This is so because
Discourse doesn't rely on a schema file system to setup a brand new
database and thus the column information will be loaded by the
application first before the post-deploy migration runs.
If there's ever a circular reference in categories, don't go into an infinite loop when generating the category slug.
Instead, keep track of parent ids, and bail out as soon as we're encountering one more than once.
Selecting the +subcategories option does not work sometimes when "lazy
load categories" is enabled because the subcategories may not be
fetched. This ensures that subcategories are loaded by requesting them
before being used.
When lazy load categories is enabled, categories should be loaded with
user activity items and drafts because the categories may not be
preloaded on the client side.
A lot of work has been put in the select kits used for selecting
categories: CategorySelector, CategoryChooser, CategoryDrop, however
they still do not work as expected when these selectors already have
values set, because the category were still looked up in the list of
categories stored on the client-side Categrories.list().
This PR fixes that by looking up the categories when the selector is
initialized. This required altering the /categories/find.json endpoint
to accept a list of IDs that need to be looked up. The API is called
using Category.asyncFindByIds on the client-side.
CategorySelector was also updated to receive a list of category IDs as
attribute, instead of the list of categories, because the list of
categories may have not been loaded.
During this development, I noticed that SiteCategorySerializer did not
serializer all fields (such as permission and notification_level)
which are not a property of category, but a property of the relationship
between users and categories. To make this more efficient, the
preload_user_fields! method was implemented that can be used to
preload these attributes for a user and a list of categories.
The category drop was rerendered after every category async change
because it updated the categories list. This is not necessary and
categories can be referenced indirectly by ID instead.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the require_topic_approval and require_reply_approval from custom fields to the new CategorySetting model.
This PR is nearly identical to #20580, which migrated num_auto_bump_daily, but since these are slightly more sensitive, they are moved after the previous one is verified.
This commit removes any logic in the app and in specs around
enable_experimental_hashtag_autocomplete and deletes some
old category hashtag code that is no longer necessary.
It also adds a `slug_ref` category instance method, which
will generate a reference like `parent:child` for a category,
with an optional depth, which hashtags use. Also refactors
PostRevisor which was using CategoryHashtagDataSource directly
which is a no-no.
Deletes the old hashtag markdown rule as well.

In addition it sets the default value to 0, which exhibits the same behaviour as when the value is NULL.
### What is this change?
The lounge category was replaced with the general category in https://github.com/discourse/discourse/pull/18097.
However, there are still a few references to the lounge category in code. In particular, `Category#seeded?` is erroring out in production looking for `SiteSetting.lounge_category_id`.
- Update welcome topic copy
- Edit the welcome topic automatically when the title or description changes
- Remove “Create your Welcome Topic” banner/CTA
- Add "edit welcome topic" user tip
A category's slug can be encoded when
`SiteSetting.slug_generation_method` has been set to "encoded". As a
result, we have to support non ASCII characters as well.
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.

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.
