* Allow delegated_type to be specified primary_key and foreign_key.
|
|
|
|
Since delegated_type assumes that the foreign_key ends with `_id`,
|
|
`singular_id` defined by it does not work when the foreign_key does
|
|
not end with `id`. This change fixes it by taking into account
|
|
`primary_key` and `foreign_key` in the options.

|
* Expose an `invert_where` method that will invert all scope conditions.
|
|
|
|
```ruby
|
|
class User
|
|
scope :active, -> { where(accepted: true, locked: false) }
|
|
end
|
|
|
|
User.active
|
|
# ... WHERE `accepted` = 1 AND `locked` = 0
|
|
|
|
User.active.invert_where
|
|
# ... WHERE NOT (`accepted` = 1 AND `locked` = 0)
|
|
```

* Restore possibility of passing `false` to :polymorphic option of `belongs_to`.
|
|
|
|
Previously, passing `false` would trigger the option validation logic
|
|
to throw an error saying :polymorphic would not be a valid option.

* Remove deprecated `database` kwarg from `connected_to`.

|
|
|
|
* Allow adding nonnamed expression indexes to be revertible.

Fixes #40732.
|
|
|
|
Previously, the following code would raise an error, when executed while rolling back,
|
|
and the index name should be specified explicitly. Now, the index name is inferred
|
|
automatically.
|
|
```ruby
|
|
add_index(:items, "to_tsvector('english', description)")
|
|
```
|
|

* Only warn about negative enums if a positive form that would cause conflicts exists.
|
|
|
|
Fixes #39065.

|
|
|
* Add option to run `default_scope` on all queries.
|
|
|
|
Previously, a `default_scope` would only run on select or insert queries. In some cases, like non-Rails tenant sharding solutions, it may be desirable to run `default_scope` on all queries in order to ensure queries are including a foreign key for the shard (ie `blog_id`).
|
|
|
|
Now applications can add an option to run on all queries including select, insert, delete, and update by adding an `all_queries` option to the default scope definition.
|
|
|
|
```ruby
|
|
class Article < ApplicationRecord
|
|
default_scope -> { where(blog_id: Current.blog.id) }, all_queries: true
|
|
end
|
|
```
|
|
|
|
*Eileen M. Uchitelle*
|
|
|
|
* Add `where.associated` to check for the presence of an association.
|
|
|
|
```ruby
|
|
# Before:
|
|
account.users.joins(:contact).where.not(contact_id: nil)
|
|
|
|
# After:
|
|
account.users.where.associated(:contact)
|
|
```
|
|
|
|
Also mirrors `where.missing`.

*Kasper Timm Hansen*
|
|
|
|
* Allow constructors (`build_association` and `create_association`) on
|
|
`has_one :through` associations.
