`association.increment_counters` and `association.decrement_counters`
works regardless of parent target is loaded or not.

`_create_record` is passed `attribute_names` only.
```
% git grep -n '_create_record(attribute_names'
lib/active_record/attribute_methods/dirty.rb:173: def _create_record(attribute_names = attribute_names_for_partial_writes)
lib/active_record/counter_cache.rb:162: def _create_record(attribute_names = self.attribute_names)
lib/active_record/locking/optimistic.rb:64: def _create_record(attribute_names = self.attribute_names)
lib/active_record/persistence.rb:738: def _create_record(attribute_names = self.attribute_names)

The target object for counter cache is not always determined by the
primary key value on the model. I'd like to extract `update_couters`
onto the `Relation` for the internal use.

`touch` option was added to `increment!` (#27660) and `update_counters`
(#26995). But that option behaves inconsistently with
`Persistence#touch` method.
If `touch` option is passed attribute names, it won't update
update_at/on attributes unlike `Persistence#touch` method.
Due to changed from `Persistence#touch` to `increment!` with `touch`
option, #31405 has a regression that `counter_cache` with `touch` option
which is passed attribute names won't update update_at/on attributes.
I think that the inconsistency is not intended. To get back consistency,
ensure that `touch` option updates update_at/on attributes.

Fix `counter_cache` double increment
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
When an `after_create` callback did `update_attributes` on a record with
multiple `belongs_to` associations with counter caches, even numbered
associations would have their counters double-incremented. Fixes to
`ActiveModel::Dirty` in 020abad fixed this.
This adds regression tests for this bug fixed incidentally in the other
commit, which also removed the need for the workaround using
@_after_create_counter_called.

`timestamp_attributes_for_updates_in_model` returns an empty
array when a model has no `updated_at` or `updated_on`.
So my previously thought uncommon case is a lot more likely
now.
This reverts commit a0a1ede8c2eb6436571eae8778033162d1f9dcc3.

Closes #27683.
Seeing a code sample that leads to what we're guarding against:
```ruby
Topic.update_counters(1, replies_count: 1, touch: [])
```
It doesn't look like a case people would ever intentionally end
up with. Thus we're better off sparing the conditional.
Note: it could happen if a method returns an empty array
that's then passed to `update_counters` and its touchy friends.
But `[].presence` can fix that once people see their query blow
up.

Supports the `touch` option from update_counters.
The default behavior is not to update timestamp columns.
|
|
|
|
|
| |
`current_time_from_proper_timezone` and timestamp attributes methods was
pushed up to class method.

Currently does not work the following example in the doc:
```ruby
# For the Posts with id of 10 and 15, increment the comment_count by 1
# and update the updated_at value for each counter.
Post.update_counters [10, 15], comment_count: 1, touch: true
# Executes the following SQL:
# UPDATE posts
# SET comment_count = COALESCE(comment_count, 0) + 1,
# `updated_at` = '2016-10-13T09:59:23-05:00'
# WHERE id IN (10, 15)
```
|
|
|
|
|
|
| |
* Rename update -> touch to remain consistent with the other docs
language of "touch"'ing.
* Remove the sentence that's repeated from just above and rephrase.

`touch_updates` calls `Time.now` via `current_time_from_proper_timezone`
so it is better to not invoke `touch_updates` if it is unnecessary.

* Refactor to use `touch_updates`
Ensures we only call `current_time_from_proper_timezone` from one place.
* Clarify touch default in tests.
Not interested in what happens when passed false but that
nothing passed means no touching.
* Backdate touched columns in tests.
We can't be sure a test progresses through time, so our
touching code may be working correctly but the test
itself is brittle.
Fix by backdating that's further in the past akin to
what the timestamps tests do:

* Expand changelog entry.
Elaborate and show examples.
Closes #26995.

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.

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

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.

When we made sure that the counter gets updated in memory, we only did
it on the has many side. The has many side only does the update if the
belongs to cannot. The belongs to side was updated to update the counter
cache (if it is able). This means that we need to check if the
belongs_to is able to update in memory on the has_many side.
We also found an inconsistency where the reflection names were used to
grab the association which should update the counter cache. Since
reflection names are now strings, this means it was using a different
instance than the one which would have the inverse instance set.
Fixes #18689

Part of a larger refactoring to remove type casting behavior from Arel
|
| |
|
|
|
|
|
| |
The hash is now string-keyed, and [_]reflect_on_association calls `to_s` on the
argument anyway.

Now that we define the macro on the reflection type we no longer
need to check `macro == :what` on each type for `belongs_to?` or
`has_one?` etc. These now default to false unless it's defined
in the reflection class.
Reuse existing belongs_to? method to check macros
We don't need to do `:belongs_to == macro` anymore becasue we
have a `belongs_to?` method. I didn't find this being used
anywhere for `has_one?` or `collection?` since they were already
fixed.

Prior to this fix, if an association had a scope with a `select`,
calls to `reset_counters` would generate invalid SQL and throw:
ActiveRecord::StatementInvalid: [$DB_ADAPTER]: wrong number of
arguments to function COUNT()
References #10710, #13648

Now the internal reflections will hold a reference to its public
representation, so when the outside world calls `Account.reflection` we
can build a list of public reflections.

Add support for counter name to be passed as parameter
on `CounterCache::ClassMethods#reset_counters`. This is
to be consistent with the other methods in the module
that all accept counter name.
