Hello all,

I have been searching for a good tutorial of how to build a gem in Rails  
3.  
I have found someones, but has not that good explained.

I haven’t build either a gem or plugin even in Rails 2.3.\*, and I don’t  
know  
if there were a change in the way a gem is built for Rails 3.

Could anyone suggest me a resource where I could begin in?

Regards,

Daniel G.

So far as I know, building gems has nothing to do with Rails. What are  
you trying to achieve?

The RubyGems docs, perhaps?

I am trying to extend Rails. I read something about Railties… that’s  
why I  
was looking for information about building Gems for Rails 3

Thanks,

Daniel G.

Hi Daniel,

Gems extend Ruby, not Rails. Plugins and Engines are the mechanisms  
to extend Rails. Of course, any extension to Ruby extends Rails as  
well and it’s not uncommon to see a Rails extension include a Ruby  
extension. But they are separate.

HTH,
