Hi,

Just wondering what the collective wisdom is regarding whether the  
environment.rb file should have a “RAILS\_GEM\_VERSION = ‘1.1.6’” type  
line  
set or not?

I noted on Dreamhost previously after a rails upgrade my site wasn’t  
working, after which I can to do and change this parameter to align with  
the  
latest Dreamhost deployed version of Rails. So should I not be setting  
this parameter such that when Dreamhost upgrades my site doesn’t die?

Tks  
Greg

Unpacking rails (whatever version your app needs) into the vendor  
directory  
is the “safest” way to ensure everything keeps working.

Hi Greg, I take it that you’re using Rails Gem. If this is the case I  
recommend that you do the following:

a) update your version environment.rb file to reference the correct  
version of Rails.

b) execute ‘rake rails:update’ in the root of your rails application

c) rake rails:freeze:gems

d) if you’re using 3rd party gems within your application, then do  
the following:

```

```

e) upload to your server

Good luck,
