How push Git sub-directory to heroku?

Question

On github I have a Rails app in a sub-directory of a directory, github.com/sadaf2605/directory/subdirectory/{rails app}. When I try to push this app to Heroku I get an error:

 !     Heroku push rejected, no Cedar-supported app detected

To [email protected]:damp-woodland-7566.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to '[email protected]:damp-woodland-7566.git'

After reading "Heroku push rejected, no Cedar-supported app detected wordpress", I learned that this sub-directory is causing the problem. But, I want this sub directory to remain at github as it helps me to organize my work yet I don't want to change the route.rb. Is it possible?

Probably best action would be to make the rails app it's own git repository and then make it a submodule of the first repository. — quandrum

Checkout the git-subtree plugin. You can use it to split subtrees from your project into subprojects and back.

git subtree push --prefix {rails app} heroku master

Clone the github project and run sudo sh install.sh to install the plugin. Full usage instructions are in the here

Subtree has since been incorporated into git so you can now run the command above without the need to install a plugin.
