ruby-on-rails - Github Action 和RAILS_MASTER_KEY

Question

我一直在尝试使用Rails设置GitHub Action ，但是RAILS_MASTER_KEY(我的假设)遇到了问题。

这是我在最后一步# Build and run tests中得到的错误消息:

rails aborted!
ActiveSupport::MessageEncryptor::InvalidMessage: ActiveSupport::MessageEncryptor::InvalidMessage
/home/runner/work/my-project/my-project/config/environment.rb:5:in `<main>'

/home/runner/work/my-project/my-project/bin/spring:15:in `<top (required)>'
bin/rails:3:in `load'
bin/rails:3:in `<main>'

Caused by:
ArgumentError: key must be 16 bytes

.github/workflows/main.yml:

name: CI
on: [push, pull_request]
jobs:
  test:
    runs-on:  ubuntu-latest
    services:
      db:
        image: postgres:11
        env:
          POSTGRES_PASSWORD: xxxxxx
        ports: ['5432:5432']
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5

    steps:
      # Download a copy of the code in the repository before running CI tests
      - name: Checkout repository
        uses: actions/checkout@v2

      # Setup Ruby
      - name: Setup Ruby
        uses: actions/setup-ruby@v1
        with: 
          ruby-version: 2.6.6

      # NPM install
      - name: NPM install with caching
        uses: bahmutov/npm-install@v1.1.0
        # with:
         # cmd: install

      # Build and run tests
      - name: Build and run tests
        env:
          DATABASE_URL: postgres://postgres:@localhost:5432/test
          RAILS_ENV: test
          RAILS_MASTER_KEY: ${{ secrets.RAILS_MASTER_KEY }}
        run: |
          sudo apt-get -yqq install libpq-dev
          gem install bundler
          bundle install --jobs 4 --retry 3
          bundle exec rails db:prepare
          bundle exec rails test

我推断这与我的RAILS_MASTER_KEY变量有关。

我检查了存储在项目的ENV变量中的 key ，它恰好是32个字节。我不确定如何最好地进行操作，并且由于担心会破坏应用程序的其他部分而犹豫不决地删除 key 。在我的书中，更可取的是将 key 设置为32字节的合法 key ，因为我不知道如何在何处……

关于如何解决这个问题有什么想法吗？

Answer 1

我遇到了同样的问题，并通过为测试环境创建凭据找到了解决方案。
EDITOR=vim rails credentials:edit --environment --test
您可能需要将测试 key 文件上传到存储库，以便可以解密凭据文件。请注意仅维护测试信息。
