Rails 3 - differences between Engines and Plugins?

Engines are just required as gems in your app. Since Rails 3.1 you even don't have to require their assets such as . Css or .

Js In Rails 2. X, Engines didn't exist, so plugins enabled people to have these functionalities but all code was copied inside the app.

Thanks for reply, so what are major differences between plugins and engines in Rails 3.0. X? I've read that engines are 'mounted' apps inside main app, but what are other differences?

What about performance? What is better? – radzio Jun 21 at 21:06 In few words, Engines are gemified plugins in Rails 3.

I don't think there are any performance difference. – apneadiving Jun 21 at 21:07 great resource here: themodestrubyist. Com/2010/03/01/… – apneadiving Jun 21 at 21:11 thanks a lot ;-) – radzio Jun 21 at 21:14 1 IMHO It definitely worth the effort though :) – apneadiving Jun 21 at 21:30.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
