Rails Postgres Github 操作错误：PG::ConnectionBad：fe_sendauth：未提供密码

Question

I am trying to get a Rails app build and test working on Github Actions using Postgresql, based on the configuration shown in this article and this article . When I push a branch to Github to kick off the action, I get the following error when the tests are run:

PG::ConnectionBad: fe_sendauth: no password supplied

I provided the username and password for the database as shown in those articles, why is it failing?

  test:

The issue is a simple omission from the configuration file: I set the env variables section for the Setup database step, but not the Run tests step. As a result, the error is correct, during that step, there is no username/password being provided so it cannot connect to the DB server. Adding it to the test step solves the problem:

- name: Run tests
  run: bundle exec rake
  env:
    RAILS_ENV: test
    POSTGRES_USER: postgres
    POSTGRES_PASSWORD: postgres
