disabling engineyard asset pipeline precompilation
13:04 < mferrier> Hey guys, on the rails 3.1 stack, anyone know how I would prevent the asset pipeline precompile from running?
13:06 < emachnic> mferrier: http://docs.engineyard.com/asset-pipeline.html
13:08 < mferrier> so I read, but I still want to be able to use the asset pipeline.
13:08 < mferrier> I just don't want the precompile step during deployments.
13:10 < emachnic> mferrier: Should be able to set config.assets.precompile to false IIRC
13:15 < mferrier> ah, I'm not explaining properly. I'm precompiling locally and committing the result into the repo. So I still want to be able to rake assets:precompile locally, but just not have that task happen in the engineyard stack.
13:15 < mferrier> changing the rails asset pipeline setup will prevent the local precompilation.
13:15 < emachnic> mferrier: Ahh. Let me check real quick
13:20 < adamholt> emachnic: mferrier: if you add your assets to public/assets we skip compiling them on the server - https://github.com/engineyard/engineyard-serverside/blob/maste
