Pushing to Heroku with Rails/ruby

I am trying to push to Heroku. I have postgres and have set the buildpacks for Heroku. However I believe it is my file structure that is causing the error.

Main-File -> ProjectName -> RubyProj ->(this is where all the ruby controllers gem stuff is)

Main-File is my git repo and I am trying to push just the RubyProj file to heroku Is there a good way to do this without doing another git init on the RubyProj file?
