Create PR from push on a given branch

[funes79]

Subject of the issue

I have a question. I configured this action to list on "on push" events on "users" branch. What I would like to know if this action can use the very same branch for PR create or it must use always a new branch to create? I tried to configure the branch parameter and set it to the same branch "users" from where the push is coming, but this resulted in a loss of the original branch (probaly re-create).

So I would like to configure a very simple scenario:
Every time a change is pushed into my branch, I would like to open a new PR againts master, approve and merge.

Thanks

Hi @funes79

The branch name that you specify in the branch input cannot be an existing branch, but what you can do is create and update a third branch which performs the merge. I think this example fits your use case.

This will create a pull request to merge in to master whenever there are changes on the users branch.

name: Update master from users
on:
  push:
    branches:
      - users
jobs:
  createPullRequest:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          ref: master
      - name: Reset master branch with users changes
        run: |
          git fetch origin users:users
          git reset --hard users
      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v3
        with:
          branch: users-update

Hi @peter-evans ,
I came up with a similar solution, just doing soft reset:

      - name: Reset master branch
        run: |
          git fetch origin master:master
          git reset --soft origin/master

So in this case I always have all the changes in the users-update transferred from users. I will need to test out your recommendation, thank you

Closing this for now since it looks like you have a solution.
