Python 在github操作上为Django设置Postgres

我一直在尝试设置工作流以测试Django应用程序，但设置工作流时遇到问题：

到目前为止，我已经创建了：

name: Django CI

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

jobs:
  build:

    runs-on: ubuntu-latest
    strategy:
      max-parallel: 4
      matrix:
        db: [postgres]
        python-version: [3.7, 3.8]
        include:
          - db: postgres
            db_port: 5432
    services:
      postgres:
        image: postgres:13
        env:
          POSTGRES_USER: postgres
          POSTGRES_PASSWORD: password
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5
        ports:
          - 5432:5432
    steps:
    - uses: actions/checkout@v2
    - name: Set up Python ${{ matrix.python-version }}
      uses: actions/setup-python@v2
      with:
        python-version: ${{ matrix.python-version }}
    - name: Install Dependencies
      run: |
        python -m pip install --upgrade pip
        pip install -r requirements.txt
    - name: Run Tests
      env:
        SECRET_KEY: vz@h6kziphf$m&xxu4$dfe4bt6h8_a_!^54yup$rk*_93d1x+h
        DEV_ENV: dev
        DB_NAME: ${{ matrix.db }}
        DB_HOST: 127.0.0.1
        DB_USER: postgres
        DB_PASSWORD: password
        DB_PORT: ${{ matrix.db_port }}
      run: |
        python manage.py test test user.tests.test_models

在我的设置文件中，我有：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': config('DB_NAME'),
        'USER': config('DB_USER'),
        'PASSWORD': config('DB_PASSWORD'),
        'HOST': config('DB_HOST', default='localhost'),
        'PORT':config('DB_PORT')
        
    } 
}

运行此管道大约需要20分钟，但会出现线程错误。我想知道什么是正确的设置方法，这样我就可以运行我的测试了
