We already have a _read_attribute method that can get the value we need
from the model. Lets define that method in AM::Dirty and use the
existing one from AR::Dirty rather than introducing a new method.

Since using a `ActiveSupport::Deprecation::DeprecatedConstantProxy`
would prevent people from inheriting this class and extending it
from the `ActiveSupport::HashWithIndifferentAccess` one would break
the ancestors chain, that's the best option we have here.

Pointed out by @matthewd that the HWIA subclass changes the
AS scoped class and top-level HWIA hierarchies out from under
existing classes.
This reverts commit 71da39097b67114329be6d8db7fe6911124531af, reversing
changes made to 41c33bd4b2ec3f4a482e6030b6fda15091d81e4a.

This constant was kept for the sake of backward compatibility; it
is still available under `ActiveSupport::HashWithIndifferentAccess`.
Furthermore, since Ruby 2.5 (https://bugs.ruby-lang.org/issues/11547)
won't support top level constant lookup, people would have to update
their code anyway.

This was never really intended to work (at least not without calling
`define_attribute_methods`, which is less common with Active Record). As
we move forward the intention is to require the use of `attribute` over
`attr_accessor` for more complex model behavior both on Active Record
and Active Model, so this behavior is deprecated.
Fixes #27956.
Close #27963.

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.

delegation
Following off of https://github.com/rails/rails/issues/15945, I realized that super
needs to be the first thing that is called in an AbstractModel's inherited method.
I was receiving errors within the inherited method of time_zone_conversion, so I tested
locally by moving super to the top of the method declaration. All exceptions went away.

A few have been left for aesthetic reasons, but have made a pass
and removed most of them.
Note that if the method `foo` returns an array, `foo << 1`
is a regular push, nothing to do with assignments, so
no self required.

kamipo/move_warning_about_composite_primary_key_to_attribute_methods_primary_key
Move the warning about composite primary key to `AttributeMethods::PrimaryKey`

Actually schema dumper/creation supports composite primary key (#21614).
Therefore it should not show the warning about composite primary key in
connection adapter.
This change moves the warning to `AttributeMethods::PrimaryKey` and
suppress the warning for habtm join table.
Fixes #25388.

Ruby 2.4 unifies Fixnum and Bignum into Integer: https://bugs.ruby-lang.org/issues/12005
* Forward compat with new unified Integer class in Ruby 2.4+.
* Backward compat with separate Fixnum/Bignum in Ruby 2.2 & 2.3.
* Drops needless Fixnum distinction in docs, preferring Integer.

I have hit this deprecation in a newly created Rails 5 application and
the suggested tip lead me to a `NoMethodError`.
It's not trivial to actually make the following work, because of the
ActiveRecord::Base class attributes setting dance in the Active Record
railtie.
config.active_record.time_zone_aware_types << :time
Decided to suggest setting it explicitly to the values we need.

We had previously updated this to attempt to map over whatever was
passed in, so that additional types like range and array could benefit
from this behavior without the time zone converter having to deal with
every known type.
However, the default behavior of a type is to just yield the given value
to `map`, which means that if we don't actually know how to handle a
value, we'll just recurse infinitely. Since both uses of `map` in this
case occur in cases where we know receiving the same object will
recurse, we can just break on reference equality.
Fixes #23241.

This is really strange, as it passes on Travis for 2.3, and it passes
for me locally on 2.2. But on travis w/ 2.2, passing `Float::INFINITY`
in is resulting in an infinite loop. This should resolve it.

This is an alternate implementation to #22875, that generalizes a lot of
the logic that type decorators are going to need, in order to have them
work with arrays, ranges, etc. The types have the ability to map over a
value, with the default implementation being to just yield that given
value. Array and Range give more appropriate definitions.
This does not automatically make ranges time zone aware, as they need to
be added to the `time_zone_aware` types config, but we could certainly
make that change if we feel it is appropriate. I do think this would be
a breaking change however, and should at least have a deprecation cycle.
Closes #22875.

The focus of this change is to make the API more accessible.
References to method and classes should be linked to make it easy to
navigate around.
This patch makes exzessiv use of `rdoc-ref:` to provide more readable
docs. This makes it possible to document `ActiveRecord::Base#save` even
though the method is within a separate module
`ActiveRecord::Persistence`. The goal here is to bring the API closer to
the actual code that you would write.
This commit only deals with Active Record. The other gems will be
updated accordingly but in different commits. The pass through Active
Record is not completely finished yet. A follow up commit will change
the spots I haven't yet had the time to update.

to reduce allocation of same object
|
|
|
|
|
| |
For reads, we never need to construct this object. The double `defined?`
check is to avoid errors in tests
|
|
|
|
|
| |
There were a few places where I missed a `create` vs `new`
before_type_cast check, and the semantics of `reload` became wrong.

We can skip the allocation of a full `AttributeSet` by changing the
semantics of how we structure things. Instead of comparing two separate
`AttributeSet` objects, and `Attribute` is now a singly linked list of
every change that has happened to it. Since the attribute objects are
immutable, to apply the changes we simply need to copy the head of the
list.
It's worth noting that this causes one subtle change in the behavior of
AR. When a record is saved successfully, the `before_type_cast` version
of everything will be what was sent to the database. I honestly think
these semantics make more sense, as we could have just as easily had the
DB do `RETURNING *` and updated the record with those if we had things
like timestamps implemented at the DB layer.
This brings our performance closer to 4.2, but we're still not quite
there.
