Im developing a rails app. Following this tutorial here:
I finished a part and wanted to push all the changes up to heroku and view them there. I can view the site on my local machine. On heroku all I see is this:

I typed in the following commands after I made my changes, saw the site was working on my local computer.
$ git add .
$ git commit -m "Finish layout and routes"
$ git checkout master
$ git push
$ git push heroku
$ heroku open
I even looked at the heroku logs but couldn’t make sense of whats going wrong! There is no content in my database, its empty. I just have views setup.
Why did you checkout to master? Are you working on another branch?
If that is the case, you will need to merge your changes to master before pushing your code (supposing you are on master which is already the case after the checkout):
Also don’t forget to migrate your database on heroku.
EDIT
To find out your current branch, type:
It will mark the current branch with a ‘*’.
