Change github repository for Rails
How do you change the git repository a rail app is pushed to? I know that this is possible because I did it a few weeks back.
Basically I have two very different versions of a app on my local machine. I would like the initial app to still point to the old repository. However, the new version needs to be placed in a completely separate repository.
When I run
git init in
myapps/old_app/ it puts
Reinitialized existing Git repository in /Users/jamespollard/rails/old_repository/.git/
When I run
git init in
myapps/new_app/ it puts
Reinitialized existing Git repository in /Users/jamespollard/rails/new_repository/.git/
However, when I try and git push anything to the repository, it still goes to the old_repository.
If I enter
$ git remote origin set-url firstname.lastname@example.org:mygithub/myapp.git
error: Unknown subcommand: origin usage: git remote [-v | --verbose] or: git remote add [-t <branch>] [-m <master>] [-f] [--mirror=<fetch|push>] <name> <url> or: git remote rename <old> <new> or: git remote rm <name> or: git remote set-head <name> (-a | -d | <branch>) or: git remote [-v | --verbose] show [-n] <name> or: git remote prune [-n | --dry-run] <name> or: git remote [-v | --verbose] update [-p | --prune] [(<group> | <remote>)...] or: git remote set-branches <name> [--add] <branch>... or: git remote set-url <name> <newurl> [<oldurl>] or: git remote set-url --add <name> <newurl> or: git remote set-url --delete <name> <url> -v, --verbose be verbose; must be placed before a subcommand
If I enter
$ git remote set-url email@example.com:mygithub/myapp.git I get the same error message as above (minus the origin error). In either case, if I run
git push origin master it still pushes to the old repository. I’ve tried adding the new repository again with the same name, but I get a error (which i would expect) saying that it already exists.

Create a new repository in GitHub for you new app, if you haven’t already. Make that new repository as origin to your new repository:
git remote add origin <github_url>
If the remote already exists, you might have to
git remote set-url origin <github_url>
Now, push to the repo.
I ran into a pretty similar situation few months ago. On the new version of the app there is a .git folder (which was also copied along with all other files when you copied the app). Heroku needs the information from .git to see if anything has changed. So when it ‘reinitialized’, heroku thinks its the same app.
So here’s what I did that resolved the problem.
- Copied the entire app folder.
- Changed app name wherever they appear (mostly in config folder, google it for a list)
- Chang secret.yml file (get a new key by rake secret) or secret token if older version
Most importantly, there should be a .git folder in your app folder (it maybe hidden).
- Delete that .git folder (it contains git info of the old app)
- Initialize a new git, git init
- and then commit and push.
Your new app should be a separate app now.
I think this might work if on heroku, worth a try:
git remote rm heroku git remote add heroku firstname.lastname@example.org:yourappname.git
or you can try this
1). open a terminal
2). Go to your_app_directory/.git/config
3). Once you open the config file then edit as follows:
url = email@example.com:old_app_name.git
url = firstname.lastname@example.org:new_app_name.git
Obviously substituting your apps old name to its new name. Hope it helps
If you take a peek at your
.git/config file, you see / check that the url is still pointing to the old remote
[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = <old_github_url>
so you wish to keep the old remote. let’s call that
First thing you can do is the rename the remote with :
git remote rename origin oldremote
Now you can add the new remote with :
git remote add origin <new_github_url>
From now on, pushing normally with just
git push will push to the new remote.
git push oldremote SHA to push to the old remote
