In 35836019, class level `update` and `destroy` suppressed
`RecordNotFound` to ensure returning affected objects. But
`RecordNotFound` is a common exception caught by a `rescue_from`
handler. So changing the behavior when a typical `params[:id]` is passed
has a compatibility problem. The previous behavior should not be
changed.
Fixes#31301.
If a relation has eager-loading values, `count` and `exists?` works
properly, but `update_all` and `delete_all` doesn't work due to missing
`apply_join_dependency`. It should be applied to work consistently.
Fixes#28863.
Class level `update` and `destroy` are using `find` in the internal, so
it will raise `RecordNotFound` if given ids cannot find an object even
though the method already affect (update or destroy) to any objects.
These methods should return affected objects even in that case.
I tried to change the expectation in #29976, but it is expected behavior
at least for now. So I added the test cases to prevent anyone change the
expectation.
Creating a new class for widgets was causing failing tests because it
clashed with other widget classes. This test does not need to create its
own class, so I changed it to an existing class.
```
ARCONN=mysql2 bin/test --seed 25364 test/cases/*test.rb -n \
"/^(?:PrimaryKeyIntegerTest#(?:test_primary_key_with_serial_integer_are_automatically_numbered)|PersistenceTest::SaveTest#(?:test_save_touch_false))$/"
```
- If the attribute is not changed, then update_attribute does not run
SQL query, this effectively means that no change was made to the
attribute.
- This change was made in https://github.com/rails/rails/commit/0fcd4cf5
to avoid a SQL call.
- But the change resulted into `nil` being returned when there was no
change in the attribute value.
- This commit corrects the behavior to return true if there is no change
in attribute value. This is same as previous behavior of Rails 4.2
plus benefit of no additional SQL call.
- Fixes#26593.
I've added a redundant test for this under the attributes API as well,
as that also causes this bug to manifest through public API (and
demonstrates that calling `reset_column_information` on the child
classes would be insufficient)
Since children of a class should always share a table with their parent,
just reloading the schema from the cache should be sufficient here.
`reload_schema_from_cache` should probably become public and
`# :nodoc:`, but I'd rather avoid the git churn here.
Fixes#22057
I’m renaming all instances of `use_transcational_fixtures` to
`use_transactional_tests` and “transactional fixtures” to
“transactional tests”.
I’m deprecating `use_transactional_fixtures=`. So anyone who is
explicitly setting this will get a warning telling them to use
`use_transactional_tests=` instead.
I’m maintaining backwards compatibility—both forms will work.
`use_transactional_tests` will check to see if
`use_transactional_fixtures` is set and use that, otherwise it will use
itself. But because `use_transactional_tests` is a class attribute
(created with `class_attribute`) this requires a little bit of hoop
jumping. The writer method that `class_attribute` generates defines a
new reader method that return the value being set. Which means we can’t
set the default of `true` using `use_transactional_tests=` as was done
previously because that won’t take into account anyone using
`use_transactional_fixtures`. Instead I defined the reader method
manually and it checks `use_transactional_fixtures`. If it was set then
it should be used, otherwise it should return the default, which is
`true`. If someone uses `use_transactional_tests=` then it will
overwrite the backwards-compatible method with whatever they set.
- Right now, there is no method to update multiple records with
validations and callbacks.
- Changed the behavior of existing `update` method so that when `id`
attribute is not given and the method is called on an `Relation`
object, it will execute update for every record of the `Relation` and
will run validations and callbacks for every record.
- Added test case for validating that the callbacks run when `update` is
called on a `Relation`.
- Changed test_create_columns_not_equal_attributes test from
persistence_test to include author_name column on topics table as it
it used in before_update callback.
- This change introduces performance issues when a large number of
records are to be updated because it runs UPDATE query for every
record of the result. The `update_all` method can be used in that case
if callbacks are not required because it will only run single UPDATE
for all the records.
One of the author fixture we have ("david") references an author address by ID.
Since we disable FK checks when inserting fixtures, this is all fine until we
try to update it, at which point MySQL would complain about the missing row
referenced by the `author_address_id`.

`reload` is meant to put a record in the same state it would be if you
were to do `Post.find(post.id)`. This means we should fully replace the
attributes hash.
There's a lot more that can be moved to these, but this felt like a good
place to introduce the object. Plans are:
- Remove all knowledge of type casting from the columns, beyond a
reference to the cast_type
- Move type_cast_for_database to these objects
- Potentially make them mutable, introduce a state machine, and have
dirty checking handled here as well
- Move `attribute`, `decorate_attribute`, and anything else that
modifies types to mess with this object, not the columns hash
- Introduce a collection object to manage these, reduce allocations, and
not require serializing the types
Topics call `serialize :content`, which means that the values in the
database should be YAML encoded, and we would only expect to receive
YAML strings to `update_column` and `update_columns`.
