Why is overriding ActiveRecord :: Base.initialize wrong?

Question

In several places, I have seen claims that overriding ActiveRecord :: Base.initialize is wrong, because it may not always be called:

• How to set default values ​​in ActiveRecord?

• http://blog.dalethatcher.com/2008/03/rails-dont-override-initialize-on.html

With any versions of ActiveRecord (3.0+), is this still true? If so, what are the specific circumstances under which it is not called, when can we expect it to be?

Answer 1

This is not what it will not be called, it is what it already is initialize, c ActiveRecord::Base.
