Hi all

I’m learning to use Rake for migration etc.  
I wonder if there’s a way to determine the currently used Rails version,  
so e.g. when installing a new engine using Rake I could check if there’s  
a version used that’s older as needed and so abort the installation. You  
know what I mean? 😉

Thanks and greetings,  
Joshua

Hi Joshua

script/about will give you the rails version (guess there’s probably a  
way  
to retrieve that programmatically).

Rails::VERSION::MAJOR  
Rails::VERSION::MINOR  
Rails::VERSION::TINY

Or for all three as a string:

Rails::VERSION::STRING
