Most of the time the table and predicate_builder
passed to Relation.new are exactly the
arel_table and predicate builder of the
given klass. This uses klass.arel_table
and klass.predicate_builder as the defaults,
so we don't have to pass them in most cases.
This does change the signaure of both Relation and
AssocationRelation. Are we ok with that?

Defined scope treats nil as `all`, but scope in associations isn't so.
If the result of the scope is nil, most features on associations will be
broken. It should treat nil as `all` like defined scope.

I investigated where `scope_for_create` is reused in tests with the
following code:
```diff
--- a/activerecord/lib/active_record/relation.rb
+++ b/activerecord/lib/active_record/relation.rb
@@ -590,6 +590,10 @@ def where_values_hash(relation_table_name = table_name)
end
def scope_for_create
+ if defined?(@scope_for_create) && @scope_for_create
+ puts caller
+ puts "defined"
+ end
@scope_for_create ||= where_values_hash.merge!(create_with_value.stringify_keys)
end
```
It was hit only `test_scope_for_create_is_cached`. This means that
`scope_for_create` will not be reused in normal use cases. So we can
remove caching `scope_for_create` to respect changing `where_clause` and
`create_with_value`.
|

|
|
|

|

This is related with #27680.
Since `where_values_hash` keys constructed by `where` are string, so we
need `stringify_keys` to `create_with_value` before merging it.

`aliased_table_name` in `Association` was added at a3502c4.
`aliased_table_name` in `JoinDependency` (added at 55854c4) is used, but
it looks like that added one in `Association` is never used from the
beginning.
|
| |
|
|
|
| |
Passing `klass.connection` is redundant because `AssociationScope` is
passed an association itself and an association has `klass`.
|
| |
|
|
| |
Because constructing `scope` is a little expensive.

Fix association with extension issues
|
| | |
| |
| |
| |
| | |
As @matthewd's suggestion, if `klass` has no default scope, it will more
faster.

This fixes the following issues.
* `association_scope` doesn't include `default_scope`. Should use `scope` instead.
* We can't use `method_missing` for customizing existing method.
* We can't use `relation_delegate_class` for sharing extensions. Should extend per association.

With the changes in #25337, double save bugs are pretty much impossible,
so we can just lift this restriction with pretty much no change. There
were a handful of cases where we were relying on specific quirks in
tests that had to be updated. The change to has_one associations was due
to a particularly interesting test where an autosaved has_one
association was replaced with a new child, where the child failed to
save but the test wanted to check that the parent id persisted to `nil`.
I think this is almost certainly the wrong behavior, and I may change
that behavior later. But ultimately the root cause was because we never
remove the parent in memory when nullifying the child. This makes #23197
no longer needed, but it is what we'll do to fix some issues on 5.0
Close #23197

callbacks
We pretty frequently get bug reports that "dirty is broken inside of
after callbacks". Intuitively they are correct. You'd expect
`Model.after_save { puts changed? }; model.save` to do the same thing as
`model.save; puts model.changed?`, but it does not.
However, changing this goes much farther than just making the behavior
more intuitive. There are a _ton_ of places inside of AR that can be
drastically simplified with this change. Specifically, autosave
associations, timestamps, touch, counter cache, and just about anything
else in AR that works with callbacks have code to try to avoid "double
save" bugs which we will be able to flat out remove with this change.
We introduce two new sets of methods, both with names that are meant to
be more explicit than dirty. The first set maintains the old behavior,
and their names are meant to center that they are about changes that
occurred during the save that just happened. They are equivalent to
`previous_changes` when called outside of after callbacks, or once the
deprecation cycle moves.
The second set is the new behavior. Their names imply that they are
talking about changes from the database representation. The fact that
this is what we really care about became clear when looking at
`BelongsTo.touch_record` when tests were failing. I'm unsure that this
set of methods should be in the public API. Outside of after callbacks,
they are equivalent to the existing methods on dirty.
Dirty itself is not deprecated, nor are the methods inside of it. They
will only emit the warning when called inside of after callbacks. The
scope of this breakage is pretty large, but the migration path is
simple. Given how much this can improve our codebase, and considering
that it makes our API more intuitive, I think it's worth doing.

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

The error message that we give today makes this error difficult to debug
if you receive it. I have no clue why we're printing the object ID of
the class (the commit doesn't give context), but I've left it as it was
deliberate.

Introduce a predicate method that doesn't need to build a scope chain,
but also hides the data structure used for representing the scope chain.

initialize_attributes
If argument of `build_record` has key and value which is same as
default value of database, we should also except the key from
`create_scope` in `initialize_attributes`.
Because at first `build_record` initialize record object with argument
of `build_record`, then assign attributes derived from Association's scope.
In this case `record.changed` does not include the key, which value is
same as default value of database, so we should add the key to except list.
Fix #21893.

Construction of relations can be a hotspot, we don't want to create one
of these in the constructor. This also allows us to do more expensive
things in the predicate builder's constructor, since it's created once
per AR::Base subclass

Reflection has an available method that is used to check if the
reflection is a collection. Any :has_many macro is considered a
collection and `collection?` should be used instead of
`macro == :has_many`.
|
| |
|
|
|
|
| |
Instead of checking for `macro == :has_one` throughout the
codebase we can create a `has_one?` method to match the `belongs_to?`,
`polymorphic?` and other methods.

The previous implementation was necessary in order to support stuff
like:
class Post < ActiveRecord::Base
default_scope where(published: true)
scope :ordered, order("created_at")
end
If we didn't evaluate the default scope at the last possible moment
before sending the SQL to the database, it would become impossible to
do:
Post.unscoped.ordered
This is because the default scope would already be bound up in the
"ordered" scope, and therefore wouldn't be removed by the
"Post.unscoped" part.
In 4.0, we have deprecated all "eager" forms of scopes. So now you must
write:
class Post < ActiveRecord::Base
default_scope { where(published: true) }
scope :ordered, -> { order("created_at") }
end
This prevents the default scope getting bound up inside the "ordered"
scope, which means we can now have a simpler/better/more natural
implementation of default scoping.
A knock on effect is that some things that didn't work properly now do.
For example it was previously impossible to use #except to remove a part
of the default scope, since the default scope was evaluated after the
call to #except.

Suppose Man has_many interests, and inverse_of is used.
Man.first.interests.first.man will correctly execute two queries,
avoiding the need for a third query when Interest#man is called. This is
because CollectionAssociation#first calls set_inverse_instance.
However Man.first.interests.where("1=1").first.man will execute three
queries, even though this is obviously a subset of the records in the
association.
This is because calling where("1=1") spawns a new Relation object from
the CollectionProxy object, and the Relation has no knowledge of the
association, so it cannot set the inverse instance.
This commit solves the problem by making relations spawned from
CollectionProxies return a new Relation subclass called
AssociationRelation, which does know about associations. Records loaded
from this class will get the inverse instance set properly.
Fixes #5717.

assignment
For one-to-one nested associations, if you build the new (in-memory)
child object yourself before assignment, then the NestedAttributes
module will not overwrite it, e.g.:
class Member < ActiveRecord::Base
has_one :avatar
accepts_nested_attributes_for :avatar
def avatar
super || build_avatar(width: 200)
end
end
member = Member.new
member.avatar_attributes = {icon: 'sad'}
member.avatar.width # => 200
