This patch brings back the functionality of passing true to the
association proxy. The behavior was deprecated with #20888 and scheduled
for removal in Rails 5.1.
The deprecation mentioned that instead of `Article.category(true)` one
should use `article#reload.category`. Unfortunately the alternative does
not expose the same behavior as passing true to the reader
did. Specifically reloading the parent record throws unsaved changes and
other caches away. Passing true only affected the association.
This is problematic and there is no easy workaround. I propose to bring
back the old functionality by introducing this new reader method for
singular associations.

Pass `set_inverse_instance` block to `sc.execute` for `SingularAssociation`

Follow up to caa178c.
caa178c updated all code which sets inverse instances on newly loaded
associations to use block. But `SingularAssociation` was forgotten it.

Because `scope` (`target_scope`) is a `AssociationRelation`.
`AssociationRelation` handles `set_inverse_instance`.

Clarifying this separation and enforcing relation immutability is the
culmination of the previous efforts to remove the mutator method
delegations.

When `require 'active_support/rails'`, 'active_support/deprecation'
is automatically loaded.

If the through class has default scopes we should skip the statement
cache.

This is to simplify the association API, as you can call `reload` on the
association proxy or the parent object to get the same result.
For collection association, you can call `#reload` on association proxy
to force a reload:
@user.posts.reload # Instead of @user.posts(true)
For singular association, you can call `#reload` on the parent object to
clear its association cache then call the association method:
@user.reload.profile # Instead of @user.profile(true)
Passing a truthy argument to force association to reload will be removed
in Rails 5.1.

Unitialized polymorphic `belongs_to` associations raise an error while
attempting to reload, as they attempt to make an uncached reload, but
don't have a klass to fetch uncachedly. In this case, `loaded?` should
be `false` anyway.

Instead use .scope_attributes? consistently in ActiveRecord to check whether
there are attributes currently associated with the scope.
Move the implementation of .scope_attributes? and .scope_attributes to
ActiveRecord::Scoping because they don't particularly have to do specifically
with Named scopes and their only dependency, in the case of
.scope_attributes?, and only caller, in the case of .scope_attributes is
contained in Scoping.

fixes #17495
|
|
|

|

For now, we don't want to take "scoping" calls in to account when
calculating cache keys for relations, so just opt-out.

Eagerly loaded collection and singular associations are ignored by the StatementCache, which causes errors when the queries they generate reference columns that were not eagerly loaded.
This commit skips the creation of the StatementCache as a fix for these scenarios.

This is to ensure that they are not accidentally called by the app code.
They are renamed to _create_record and _update_record respectively.

Since Rails 4.0, we add an ORDER BY in the `first` method to ensure consistent
results among different database engines. But for singular associations this
behavior is not needed since we will have one record to return. As this
ORDER BY option can lead some performance issues we are removing it for singular
associations accessors.
Fixes #12623.

ability to override class.new to return a subclass based on
a virtual attribute in the attributes hash.
