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".
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
* FEATURE: add category banner for why a user cannot post
Adds a category banner for why a user is unable to post in a category.
Also adds an extra alert for the user when a user is unable to create a topic in a
category and they still try and click on the disabled-looking new topic
button.
Previously, categories without any topics were being excluded from the UPDATE query. This means the counter gets stuck, and the category cannot be deleted. This change ensures that the counters get correctly set to zero.
- Using h4 instead of h3 for sub-categories.
- Show category description if it does not have subcategories.
- Implemented equivalent for mobile-view.
- Include description_excerpt in basic serializer. This is needed for
displaying second-level categories in category list.
Follow-up to 9253cb79e3.
In a category's settings, the Tags tab has two new fields to
specify the number of tags that must be added to a topic
from a tag group. When creating a new topic, an error will be
shown to the user if the requirement isn't met.
The routes for categories are changing. The scheme that I intend to move
us to is:
/c/*slug_path/(:id)/ENDPOINT
/c/*slug_path/(:id)
This commit adds support for the new scheme to the server side without
dropping support for existing URLs. It is necessary to support existing
URLs for two reasons:
* This commit does not change any client side routing code,
* Posts that contain category hashtags that refer to a root category
are baked into URLs that do not fit this new scheme, (/c/[id]-[slug])
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
* FIX: Do not encode the URL twice
Now that we encode slugs in the server we don't need this anymore.
Reverts fe5na33
* FIX: More places do deal with encoded slugs
* the param is a string now, not a hash
* FIX: Handle the nil slug on /categories
* DEV: Add seeded? method to identity default categories
* DEV: Use SiteSetting to keep track of seeded categories
Slugs can be the empty string, but the added index didn't account for
that. This commit changes the migration, stopping it from being unique
so that it can be applied everywhere and adds another migration that
recreates the index properly.
When a category has a subcategory, we ensure that no one who can see the
subcategory cannot see the parent. However, we don't take into account
the fact that, when no CategoryGroups exist, the default is that
everyone has full permissions.
If the setting is turned on, then the user will receive information
about the subject: if it was deleted or requires some special access to
a group (only if the group is public). Otherwise, the user will receive
a generic #404 error message. For now, this change affects only the
topics and categories controller.
This commit also tries to refactor some of the code related to error
handling. To make error pages more consistent (design-wise), the actual
error page will be rendered server-side.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
Previously users were still allowed to create topic via API even if
uncategorized was disabled.
Not 100% happy with all this special casing, but I guess we have to do
something.
This also splits up a mega spec now that we have fab! into a more easy to
understand structure (I hope)
- Correct create_category_definition to skip validations and use a
transaction, no longer able to create corrupt topics
- ensure_consistency now clears topic_id if pointing at deleted or missing
topic_id
- Stop creating category definition topics for uncategorized
This removes all uses of both `send` and `public_send` from consumers of
SiteSetting and instead introduces a `get` helper for dynamic lookup
This leads to much cleaner and safer code long term as we are always explicit
to test that a site setting is really there before sending an arbitrary
string to the class
It also removes a couple of risky stubs from the auth provider test
Use this event to filter the list of auto bumped topics.
EG:
on(:filter_auto_bump_topics) do |_category, filters|
filters.push(->(r) { r.where(<<~SQL)
NOT EXISTS(
SELECT 1 FROM topic_custom_fields
WHERE topic_id = topics.id
AND name = 'accepted_answer_post_id'
)
SQL
})
end
- We spread out bumping through the day, if you are bumping
4 topics then a topic will be bumped every 6 hours
- We add a small, bumping action at the bottom of the post to
denote a topic got bumped
