I’m getting very confused with how the versions of Rails work and wondered if somebody could explain it to me (preferably as basically as possible, treat me as a beginner!) The situation is that I have a desktop machine that has Rails 1.2.3 in which I created a couple of sites. I then uploaded them to a hosted server that is running Rails 1.2.5. The apps run fine on this server. I have now bought a laptop and if I install Rails it will be at version 2+. I also want to update the version I am running on my desktop. My hosts have no plans at present to upgrade to version 2 of Rails. Here are my questions: What line would it be that forces the production site on the hosted server to use their version of rails rather than the version it was created in? How can I update my desktop machine’s version of Rails and then continue to develop these 2 sites if they specify that a previous version should be used? I’ve read about freezing edge Rails. This seems to imply that you include a whole version of rails as part of the site’s code. Can I do this with these projects and effectively choose which version of Rails is used on a project by project basis? Would I be able to freeze a version of Rails 2.x onto my hosted server to enable me to make use of Rails 2.0 in a hosted environment or will I have to wait until they upgrade? I hope that makes sense. Thanks in advance, DAZ ---

That version is then using, independantly of what gems are installed. It can be edge, or just a regular version of rails (so that the version you use is independant from what gems are installed, you have have a different version for each project etc…). You can certainly freeze 2.0 into a project and run that on a server which only has 1.2 installed (or even no version of rails). Fred ---

Thanks for the reply Fred. This sounds like good news - basically I can choose which version of Rails each individual application uses and this won’t depend on which machine it is running? Will ruby still have to be installed on the host? Are there any good instructions of how to freeze a copy of rails into an application and do you need rails installed in the first place to do it? Another question is what if I use some ruby gems. I often install bluecloth so that I can use markdown and luckily my host also has this installed. Can I freeze this into the app aswell? cheers, DAZ On Jan 15, 9:58 am, Frederick C. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Either rake rails:freeze:gems (in which case you do need the gems) or rake rails:freeze:edge . You can specify which tag to use, so you can get it to lock to the 1.2.5 release for example. > Another question is what if I use some ruby gems.

You can do stuff like [Vendor Everything — err.the\_blog](http://errtheblog.com/posts/50-vendor-everything) Fred
