Filezilla uploaded files to rails via sftp won't show up

hi,

I’m a Ruby on Rails noob, I am using the one click application which I can access via terminal ssh and browser.

I downloaded the rails project file (via SFTP Filezilla) to my local machine (Mac OS X Yosemite), I want to make changes to these files then re-upload it back to the same location via SFTP Filezilla. Therefore practically changing the file (View>Home>index.html.erb). I added a simple line of code which is a heading. But when I checked my rails home page, the change I did on the code is not reflecting. (my H1 tag is not showing up).

Is there something that I missed doing for me to edit my code and re-upload it back to my digitalocean ip directory?

Thanks!
