Rails 可以通过 GitHub 个操作连接到 PostgreSQL

Question

我已经与 GitHub 行为斗争了一段时间了。在使用 Travis 一段时间后，我不得不切换到 GitHub Action，并且无法将其设置为 Rails 应用程序的运行测试。问题是 Rails 没有启动数据库以连接到迁移并从迁移创建数据库。

这是我的工作流 .yml 文件：

name: Ruby on Rails CI

on:
  push:
    branches: [ master, develop ]
  pull_request:
    branches: [ master, develop ]

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        ruby-version: ['2.6', '2.7', '3.0']

services:
  postgres:
    env:
      POSTGRES_DB: postgres        
      POSTGRES_PASSWORD: postgres
      POSTGRES_USER: postgres
    image: postgres:13
    ports:
    - 5432:5432
    options: --health-cmd pg_isready --health-interval 10s --health-timeout 5s --health-retries 5
    
steps:
- uses: actions/checkout@v2

- name: Set up Ruby
  uses: ruby/setup-ruby@v1
  with:
    ruby-version: 2.7.3
    bundler-cache: true # runs 'bundle install' and caches installed gems automatically

- name: Install dependencies
  run: |
    yarn install
    
- name: Build and Test
  run: |
    sudo apt-get -yqq install libpq-dev
    bundle exec rake db:migrate
    bundle exec rake test

我从“操作”选项卡中得到的错误：

我看过多个关于这个问题的视频和 Stack Overflow 讨论，但到目前为止没有任何效果。感谢任何帮助。

尝试通过正确的测试数据库配置环境。在 database.yml 中检查并设置测试数据库的变量。

test:
  <<: *default
  database: <%= ENV.fetch('PG_DATABASE', 'postgres') %> 
  host:     <%= ENV.fetch('PG_HOST',  'localhost') %>
  username: <%= ENV.fetch('PG_USER', nil) %>
  password: <%= ENV.fetch('PG_PASSWORD', nil) %>
  port:     <%= ENV.fetch('PG_PORT', 5432) %>

或将测试数据库配置 ENV 添加到您的 workflow.yml:

- name: Build and Test
  env:
    PG_DATABASE: postgres
    PG_HOST: localhost
    PG_PORT: 5432
    PG_USER: postgres
    PG_PASSWORD: postgres
    RAILS_ENV: test
  run: |
    sudo apt-get -yqq install libpq-dev
    bundle exec rake db:migrate
    bundle exec rake test
