Hi all,

I’m developing a CMS prototype and I plan to use rails 3. The thing is,  
do I need to change anything important in my rails 2 application to  
support rails 3 features? Like in environment, initializers or any  
“core” file, or I can just freeze rails edge in vendor and I get the  
same stuff as if I had generated the application with rails edge  
command?

thanks in advance.

Rodrigo, It’s really hard to say whether your will or will not work on  
Rails  
3.0.  
Thus, I would recommend that you check your Rails 3.0 compatibility by  
testing  
your app against Edge. You might want to keep up to date with the  
threads/blogs in regards to Rails 3.0:

Lastly, Rails 3.0 will require Ruby 1.8.7 and prefer Ruby 1.9.2.

Good luck,

-Conrad

Hi Rodrigo,

We’re in the same situation as you. After some hard working with rails 3  
we  
just come back to rails 2.3. IMHO, rails 2.3 provides much more better  
experience than rails 3: all plugins work instantly.

If you’d like to try rails 3, prepare to roll your own rspec/cucumber  
generator and common module like authentication.

Best,  
Jan
