How to check-in assets in a Rake Task?

I'm buildin开发者_运维知识库g a rails rake task to check-in assets and running into issues: errors:

# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)

Here are the commands in the rake task:

def push_assets
  puts "===== Pushing assets to github..."

  system("git add public/assets")
  system("git commit -m 'production prepared assets' ")
  system("git push")

  puts "===== Push complete..."
end

Any ideas what is being done wrong in the method? Thanks

Looks like you have already committed the changes. ( did you run this script once before?)

To redo the commit, you can do git reset HEAD^

To make your task idempotent, you can use git status --porcelain or git diff --name-only or something to see if there are changes to be checked-in in assets. If there are, only then proceed with the commit.
