I have created an instance method which is also a callback (if that makes sense) which does some stuff thats irrelevant. I would love to be able to just call:
class Model < ActiveRecord::Base
fix_camelcase_columns
end
Instead at the moment I have this:
def after_find
self.class.columns.each do |column|
self.instance_eval("def #{column.name.to_underscore}; self.#{column.name}; end;")
end
end
I would love to abstract this and use it on other classes. Any pointers?
Well, you can open up ActiveRecord::Base and throw a method there:
class ActiveRecord::Base
def self.fix_camelcase_columns
define_method :after_find do
...
end
end
end
For a cleaner way, create a module:
module CamelcaseFixer
def self.included(base)
base.extend(self)
end
def fix_camelcase_columns
define_method :after_find do
...
end
end
end
and then in your model do
class Model < ActiveRecord::Base
include CamelcaseFixer
fix_camelcase_columns
end
Didn't test the code, see if it works.
