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
