This is necessary because as of 5ac2341 `hstore` columns are always stored
as `Hash` with `String` keys. `ActiveRecord::Store` expected the attribute to
be an instance of `HashWithIndifferentAccess`, which led to the bug.

With the addition of String#in_time_zone and Date#in_time_zone
we can simplify the type casting code by checking if the value
has an `in_time_zone` method.

Previously, when `time_zone_aware_attributes` were enabled, after
changing a datetime or timestamp attribute and then changing it back
to the original value, `changed_attributes` still tracked the
attribute as changed. This caused `[attribute]_changed?` and
`changed?` methods to return true incorrectly.
Example:
in_time_zone 'Paris' do
order = Order.new
original_time = Time.local(2012, 10, 10)
order.shipped_at = original_time
order.save
order.changed? # => false
# changing value
order.shipped_at = Time.local(2013, 1, 1)
order.changed? # => true
# reverting to original value
order.shipped_at = original_time
order.changed? # => false, used to return true
end

This improves memory and performance without having to use symbols which
present DoS problems. Thanks @headius and @tenderlove for the
suggestion.
This was originally committed in
f1765019ce9b6292f2264b4601dad5daaffe3a89, and then reverted in
d3494903719682abc0948bef290af0d3d7b5a440 due to it causing problems in a
real application. This second attempt should solve that.

require 'active_record'

ActiveRecord::Base.establish_connection(adapter: 'sqlite3', database: ':memory:')

We should not need any `serialized_attributes` checks outside `ActiveRecord::AttributeMethods::Serialization` module.

This reverts commit f1765019ce9b6292f2264b4601dad5daaffe3a89.
|
| |
| |
| |
| | |
Public method `attributes_before_type_cast` used to return internal AR structure (ActiveRecord::AttributeMethods::Serialization::Attribute), patch fixes this. Now behaves like `read_attribute_before_type_cast` and returns unserialised values.

It's sometimes hard to quickly find where deprecated call was performed, especially in case of migrating between Rails versions. So this is an attempt to improve the call stack part of the warning message by providing caller explicitly.

In the end I think the pain of implementing this seamlessly was not
worth the gain provided.
The intention was that it would allow plain ruby objects that might not
live in your main application to be subclassed and have persistence
mixed in. But I've decided that the benefit of doing that is not worth
the amount of complexity that the implementation introduced.
