You can now add an :inverse_of option to has_one, has_many and belongs_to associations. This is best described with an example:
class Man < ActiveRecord::Base
has_one :face, :inverse_of => :man
end
class Face < ActiveRecord::Base
belongs_to :man, :inverse_of => :face
end
m = Man.first
f = m.face
Without :inverse_of m and f.man would be different instances of the same object (f.man being pulled from the database again). With these new :inverse_of options m and f.man are the same in memory instance.
Currently :inverse_of supports has_one and has_many (but not the :through variants) associations. It also supplies inverse support for belongs_to associations where the inverse is a has_one and it's not a polymorphic.

Example: ActiveSupport::JSON.backend = "JSONGem"
All internal Rails JSON encoding is now handled by ActiveSupport::JSON.encode(). Use of #to_json is not recommended, as it may clash with other libraries that overwrite it. However, you can recover Rails specific functionality
if you really want to use #to_json.
gem 'json'
ActiveSupport::JSON.backend = "JSONGem"
class ActiveRecord::Base
alias to_json rails_to_json
end
Resolved all the conflicts since 2.3.0 -> HEAD. Following is a list
of commits that could not be applied cleanly or are obviated with the
abstract_controller refactor. They all need to be revisited to ensure
that fixes made in 2.3 do not reappear in 3.0:
2259ecf368
AR not available
* This will be reimplemented with ActionORM or equivalent
06182ea02e
implicitly rendering a js response should not use the default layout
[#1844 state:resolved]
* This will be handled generically
893e9eb995
Improve view rendering performance in development mode and reinstate
template recompiling in production [#1909 state:resolved]
* We will need to reimplement rails-dev-boost on top of the refactor;
the changes here are very implementation specific and cannot be
cleanly applied. The following commits are implicated:
199e750d463942cb406ef8ea9f85d4e3b166aab3ae9f258e0344423126c60cb020b4d6
workaround for picking layouts based on wrong view_paths
[#1974 state:resolved]
* The specifics of this commit no longer apply. Since it is a two-line
commit, we will reimplement this change.
8c5cc66a83
make action_controller/layouts pick templates from the current instance's
view_paths instead of the class view_paths [#1974 state:resolved]
* This does not apply at all. It should be trivial to apply the feature
to the reimplemented ActionController::Base.
87e8b16246
fix HTML fallback for explicit templates [#2052 state:resolved]
* There were a number of patches related to this that simply compounded
each other. Basically none of them apply cleanly, and the underlying
issue needs to be revisited. After discussing the underlying problem
with Koz, we will defer these fixes for further discussion.
