Github actions: read branch changes on workflow_run

Question

I have two workflows: CI (for continuous integration) and CD (for continuous delivery). My goal is if someone makes a changes to branches other than master branches, I want to execute CD as well on that branch

But its taking ref as master in CD

ci.yaml

name: CI
on:
 push:
 branches:
 - master
 - test
 pull_request:
 types: [opened, synchronize, ready_for_review]
 branches:
 - master

cd.yaml

name: CD
on:
 workflow_run:
 workflows: ["CI"]
 types: 
 - completed
jobs:
 deployment:
 name: CD
 runs-on: ubuntu-latest 
 steps:
 - uses: actions/checkout@v2
 with:
 ref: ${{ github.ref }} 

When I make changes to test branch, CD is not picking up the changes in test branch, instead working with defaul master config. How to make workflow_run to pick up branch changes

• GuiFalourd: I don't know if it's possible to do it through a workflow_run event, but I believe it would be possible through a repository_dispatch event, as you could send the branch reference in the dispatch request on the CI workflow to be used on the second workflow (CD).

Answer 1

If I correctly understood what you are looking for, i.e. having the name of the original branch whose CI workflow triggered CD, changing

github.ref

with:

github.event.workflow_run.head_branch

will solve the problem
