Rails - Dec 2006 - activerecord::base code

Ahoy,

Was looking through AR::base.

Could all this


  class ActiveRecordError < StandardError #:nodoc:
  end
  class SubclassNotFound < ActiveRecordError #:nodoc:
  end
  class AssociationTypeMismatch < ActiveRecordError #:nodoc:
  end
... (about 10 more)

be replaced with

  ["SubclassNotFound","AssociationTypeMismatch",
etc...].each do
''error_name''
    class error_name < ActiveRecordError end
  end


?

Nope. Did you try writing a little script to see if it''s equivalent?

[ "A", "B", "C" ].each do |c|
    class c < StandardError
    end
end

... doesn''t work. Run it to see why.

But this does work;

[ "A", "B", "C" ].each do |c|
    eval "class #{c} < StandardError
    end"
end

... maybe
;)
