Related to - https://github.com/mastodon/mastodon/pull/35458 - which added a batch base class, and to - https://github.com/mastodon/mastodon/pull/35872 - which envisions a world where form objects tell the view what to do.
Background here...
- The `Form::AccountBatch` form object is used in a few different places, for somewhat varied purposes
- The user relationships view uses it on a show page, which does a PUT to update, and uses the `follow`, `unfollow`, `remove_from_followers`, and `remove_domains_from_followers` "actions" of the form model
- The admin accounts view shows a form on index view, does POST to batch action, uses the `suspend`, `approve` and `reject` actions.
- The admin relationships view (for admins only) also has a form on index and does a POST back to that same spot
- The admin/follow_recommendations page has a form on show and does PUT to update, using the `suppress_follow_recommendation` and `unsuppress_follow_recommendation` actions
So, while these are all related in that they supply an `accounts_ids` array, the actual things that they "bulk update" are Follow (from relationships), FollowRecommendationSuppression (from follow recs) and Account (from accounts). This is a little inconsistent with other of the "batch form model" classes, which tend to update the same domain concept (ie, CustomEmojiBlock, IpBlockBatch, EmailDomainBlockBatch, etc) that they are named after (and in some cases that a "filter" class is named after).
All that said, the changes here:
- Pull out `Form::FollowRecommendationBatch` and `Form::RelationshipBatch` classes, which more closely align with the domain concept they are bulk updating (open to naming suggestions here)
- Mark both of these as `persisted?` true so that their form views will infer correct HTTP action
- Add some missing coverage to existing class, and coverage for new classes as well
It would be pretty straightforward to chop this up into smaller pieces, if any of "just the coverage first", "just the boolean attribute", "one new batch class at a time", etc - were more appealing.
Possible follow-up:
- In the existing `Form::AccountBatch`, use attributes API for boolean `select_all_matching` value, remove query method
- Convert the relationships controller spec to mix of request/system specs, round out coverage
- Most (all maybe?) of the "batch actions" are doing a `POST` to a `batch` action on the controller of whatever they are related to. Might be worth looking at what the diff would look like to move these all to nested controllers where they did a `PUT to */batches#update` with restful routing, etc.
* Add trending statuses
* Fix dangling items with stale scores in localized sets
* Various fixes and improvements
- Change approve_all/reject_all to approve_accounts/reject_accounts
- Change Trends::Query methods to not mutate the original query
- Change Trends::Query#skip to offset
- Change follow recommendations to be refreshed in a transaction
* Add tests for trending statuses filtering behaviour
* Fix not applying filtering scope in controller
