Decorator pattern in Ruby... what do you think about the implementation?

Rails

Hello all
I was wondering about how you guys are implementing the decorator
patterns in Ruby? Here is a thought to share with.

Could you please share your thoughts about this implementation?

Have a great time :slight_smile:
Take care.

You could easily do that in a few lines:

There are quite a few blog posts on the net when you google for “ruby
decorator pattern”.

About your implementation, I prefer the syntax from the post above,
simply because it reads more natural. Other than that, yours does seem
a viable solution (only skimmed it, but seems fine) :slight_smile:

Best regards

with any of its magic that you might be fubaring otherwise.

Agreed.

Hello Peter and Michael,
Thanks for your comments. Keep tuned up with my blog. I will be
investigating on more design patterns to implement in Ruby (not in
Rails style) :smiley: and of course need to thoughts to share.

It’s an interesting pure Ruby implementation, but it’s not a great
Rails implementation, because it’s overloading “method_missing”
without a call to super.
