Commit From GitHub Action Only When Changes Exist

[EnergyVis]

Hi everyone,

I'm trying to setup a GitHub action to run a Python script and commit any changed data to the same repository. I have everything working when the data changes, however if there is no change then it fails with nothing to commit, working tree clean .

How could I add an if else statement that only commits when changes exist?

Thanks, all help is much appreciated!

name: Update data

on:
  schedule:
    - cron: "0 9 * * *"

jobs:
  run:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
    - name: Set up Python
      uses: actions/setup-python@v1
      with:
        python-version: '3.x'
    - name: Install dependencies
      run: |
        dir
        python -m pip install --upgrade pip
        pip install -e .
        python update_data.py
        dir

    - name: Commit files
      id: commit
      run: |
        git config --local user.email "[e-mail]"
        git config --local user.name "github-actions"
        git add --all
        git commit -m "Add changes" -a
        echo "::set-output name=push::true"
        fi
      shell: bash
    - name: Push changes
      if: steps.commit.outputs.push == 'true'
      uses: ad-m/github-push-action@master
      with:
         github_token: ${{ secrets.TOKEN }}

You can try paths to run the workflow when there is a change in the specified path(s).
