Rails - alias_method_chain with a 'attribute=' method

To fix the issue you can do I'd like to 'add on' some code on a model's method via a module, when it is included. I think I should use alias_method_chain, but I don't know how to use it, since my 'aliased method' is one of those methods ending on the '=' sign: , alias_method_chain is a simple, two-line method:
def alias_method_chain( target, feature )
  alias_method "#{target}_without_#{feature}", target
  alias_method target, "#{target}_with_#{feature}"
end
alias_method :foo_without_bar=, :foo=
alias_method :foo=, :foo_with_bar=
def foo_with_bar=(value)
  ...
end

seems to work fine How are you requiring the module? If you are running in development mode, the User class could be reloaded after the first request which would clear out your patch and alias_method_chain.
You can get around it by doing the patch inside of a Dispatcher (which runs with every code reload):
require 'dispatcher'

Dispatcher.to_prepare do
  Issue.send(:include, MyMooPatch)
end

How to decorate a method in Ruby without alias_method_chain

This might help you I would either perform subclassing (per @iain's answer) or a custom module inclusion in your own instances:
module LoggerLiner
  def message(*args)
    puts "="*15
    super
  end
end

log = Logger.new(STDOUT)
log.extend(LoggerLiner)

Undefined method with alias_method_chain

like below fixes the issue Model defines attribute's getters & setters dynamically. So alias_method_chain had't found setter for attribute.

undefined method `alias_method_chain' for ActionDispatch::Request:Class

With these it helps Rails 5.1 dropped alias_method_chain in favor of Module#prepend; Wiselinks hasn't been updated since 2014 and is not compatible with Rails 5.
