This fixes the following warnings.
```
/rails/activemodel/test/cases/nested_error_test.rb:9: warning: method redefined; discarding old test_initialize
/rails/activemodel/test/cases/error_test.rb:29: warning: previous definition of test_initialize was here
```
This adds `.attribute_names` and `#attribute_names` to
`ActiveModel::Attributes` along the same lines as the corresponding
methods in `ActiveRecord::AttributeMethods` (see
[`.attribute_names`][class_method] and
[`#attribute_names`][instance_method].
While I was here I also added documentation for '#attributes', which I
added in 043ce35b186. The whole class is still `#:nodoc:` so I don't
think this will have any effect for now.
[class_method]: cc834db1d0/activerecord/lib/active_record/attribute_methods.rb (L154-L160)

Each acceptance validator applied to a model class includes an instance
of a module builder (LazilyDefineAttributes) into that class. In tests,
if the original model class is not subclassed, these modules pile up and
cannot be removed, potentially leading to flakey specs and false
positive/negatives.
To avoid this, always use subclasses in tests whose names (constants)
can be removed when the test is done.
Many operations need grouping of errors by attributes, e.g. ActiveRecord::AutosaveAssociation#association_valid?
Refactor other methods using group_by_attribute
Allow `each` to behave in new way if block arity is 1
Ensure dumped marshal from Rails 5 can be loaded
Make errors compatible with marshal and YAML dumps from previous versions of Rails
Add deprecation warnings
Ensure each behave like the past, sorted by attribute
Add initialize_dup to deep dup.
Move proc eval and flexible message position out to Errors,
because proc eval is needed for Errors#added? and Errors#delete
Before 34cc301, type casting by boolean attribute when querying is a
no-op, so finding by truthy boolean string (i.e.
`where(value: "true") # => value = 'true'`) didn't work as expected
(matches it to FALSE in MySQL #32624). By type casting is ensured, a
value on boolean attribute is always serialized to TRUE or FALSE.
In PostgreSQL, `where(value: :false) # => value = 'false'` was a valid
SQL, so 34cc301 is a regresson for PostgreSQL since all symbol values
are serialized as TRUE.
I'd say using `:false` is mostly a developer's mistake (user's input
basically comes as a string), but `:false` on boolean attribute is
serialized as TRUE is not a desirable behavior for anybody.
This allows falsy boolean symbols as false, i.e.
`klass.create(value: :false).value? # => false` and
`where(value: :false) # => value = FALSE`.
Fixes#35676.
This reverts commit 52fddcc653458456f98b3683dffd781cf00b35fe.
52fddcc was to short-circuit `ensure_in_range` in `cast_value`. But that
caused a regression for empty string deserialization.
Since 7c6f393, `ensure_in_range` is moved into `serialize`. As 52fddcc
said, the absolute gain is quite small. So I've reverted that commit to
fix the regression.
This is a follow-up of #35310.
Currently `Topic.find_by(id: "not-a-number")` matches to a `id = 0`
record. That is considered as silently leaking information.
If non numeric string is given to find by an integer column, it should
not be matched to any record.
Related #12793.
`value_from_multiparameter_assignment` defined by
`AcceptsMultiparameterTime` helper requires `default_timezone` method
which is defined at `TimeValue` helper.
Since `Date` type doesn't include `TimeValue`, I've extracted `Timezone`
helper to be shared by `Date`, `DateTime`, and `Time` types.
- If you had a PORO that acted like a Numeric, the validator would
work correctly because it was previously using `Kernel.Float`
which is implicitely calling `to_f` on the passed argument.
Since rails/rails@d126c0d , we are now using `BigDecimal` which does
not implicitely call `to_f` on the argument, making the validator
fail with an underlying `TypeError` exception.
This patch replate the `is_decimal?` check with `Kernel.Float`.
Using `Kernel.Float` as argument for the BigDecimal call has two
advantages:
1. It calls `to_f` implicetely for us.
2. It's also smart enough to detect that `Kernel.Float("a")` isn't a
Numeric and will raise an error.
We don't need the `is_decimal?` check thanks to that.
Passing `Float::DIG` as second argument to `BigDecimal` is mandatory
because the precision can't be omitted when passing a Float.
`Float::DIG` is what is used internally by ruby when calling
`123.to_d`
https://github.com/ruby/ruby/blob/trunk/ext/bigdecimal/lib/bigdecimal/util.rb#L47
- Another small issue introduced in https://github.com/rails/rails/pull/34693
would now raise a TypeError because `Regexp#===` will just return
false if the passed argument isn't a string or symbol, whereas
`Regexp#match?` will.
When assigning a hash to a time attribute that's missing a year
component (e.g. a `time_select` with `:ignore_date` set to `true`)
then the year defaults to 1970 instead of the expected 2000. This
results in the attribute changing as a result of the save.
Before:
event = Event.new(start_time: { 4 => 20, 5 => 30 })
event.start_time # => 1970-01-01 20:30:00 UTC
event.save
event.reload
event.start_time # => 2000-01-01 20:30:00 UTC
After:
event = Event.new(start_time: { 4 => 20, 5 => 30 })
event.start_time # => 2000-01-01 20:30:00 UTC
event.save
event.reload
event.start_time # => 2000-01-01 20:30:00 UTC
Since Rails 6.0 will support Ruby 2.4.1 or higher
`# frozen_string_literal: true` magic comment is enough to make string object frozen.
This magic comment is enabled by `Style/FrozenStringLiteralComment` cop.
* Exclude these files not to auto correct false positive `Regexp#freeze`
- 'actionpack/lib/action_dispatch/journey/router/utils.rb'
- 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb'
It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333
Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed.
* Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required
