How to make sure that there are different versions of files on the local machine and in the git repository?

Question

git

Ruby on rails 4 project, deploy by capistrano. On ubuntu+nginx+unicorn server. On the local machine windows+thin.
You need to have different gemfile and gemfile.lock on local machine and git.
If you use .gitignore, then the files are removed from git.

Answer 1

So far, only the creation of local and deployment branches has come to mind. But you have to switch between them.
But in theory, files shouldn't be deleted unless you do a git rm.

Answer 2

I think it's worth highlighting different groups for each environment (development and production) in one Gemfile. On the local machine use development and on the server production. Read more about it here: bundler.io/v1.5/groups.html
PS The translation is a bit simplified.
