Where do Gems Live (e.g. CKEditor)

I'm a Rails newbie and I have added the CKEditor Gem which is working
okay. To configure the gem though, you have to edit the config file,
which is also working when I do that. However, when I push to github and
pull to my other computer, the config file is not changed.

This lead me to the following broader question: when you use a gem,
where does the code go and how can you make sure it all gets deployed -
especially with regards to CKEditor as the other stuff seems to work.

I accept this may be a really stupid question.

Are you using something like rvm/rbenv? if not then you can do "which
rails" and you'll get the path where the rails gem is.
If you are using a ruby version manager, then it's inside .rvm or .rbenv
folder, in a folder called "gems", as you are downloading the gem as a git
repository (that's my guess) I assume it will be inside a "bundler" folder.

Yes, I'm using rvm. So the CKeditor gem will be there. If I want to
modify the gem and have that modification passed to my deployed site do
I need to move it to within my assets (or whatever)? I ask because
otherwise when I run bundle install on the deployed site (heroku hosted)
it will just install the regular ckeditor files won't it, without my
changes?

And thanks a lot for the response!

As far as I understand, you're modifying the gem by your own. I've donde
this with simple form and once with ckeditor.
This is what I did then:

- forked the github repository
- made the changes, commit them and push to my fork
- then in Gemfile

   gem 'simple_form', :*git* => '*git*://github.com/MY_ACCOUNT/simple_form.*
git*'

If your site is in heroku, then I suggest doing this.

You might be better to use the technique described in [1] rather than
modifying the one in the gem itself.
