【问题标题】:How to skip active record for existing project in Rails 6如何在 Rails 6 中跳过现有项目的活动记录
【发布时间】:2020-05-19 08:02:24
【问题描述】:

我有一个现有的 Rails 项目,它是在 API 模式下创建的,没有使用 DB。在尝试部署到 Heroku 时,我遇到了很多与 ActiveRecord 相关的错误。

    【解决方案1】:

    要在现有项目中复制skip-active-record 设置,请按照this answer 中的步骤操作

    删除 config/environments/development.rb -> config.active_storage.service = :local

    删除 config/environments/production.rb -> config.active_storage.service = :local

    删除 config/environments/test.rb -> config.active_storage.service = :local

    删除 bin/setup -> puts "\n== Preparing database ==" system! 'bin/rails db:prepare'

    删除config/storage.yml

    删除 test/test_helper.rb # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order. fixtures :all
