当我运行heroku run rake db:migrate in production时,我收到此错误。
弃用警告:不推荐使用config.serve_static_files
,将在Rails 5.1中删除。
请改用config.public_file_server.enabled = true
。
(从/app/config/environments/production.rb:25中的块调用)
我在stackoverflow上尝试了一些解决方案,但我无法解决问题。
这是我的production.rb文件
Rails.application.configure do

是,请将弃用的代码替换为:
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?

首先,这不是一个错误,它是一个警告,并从您的文件config.serve_static_files中删除此行,而不是使用config.public_file_server.enabled = true

可以替换
吗?config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
与
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
看看这是否有效?

警告本身说:
DEPRECATION WARNING:不推荐使用config.serve_static_files 在Rails 5.1中删除。请使用config.public_file_server.enabled =而是真的。 (从/app/config/environments/production.rb:25中的块调用)
在 production.rb 文件中的第25行:
你需要替换:
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
与
config.public_file_server.enabled = true # ENV['RAILS_SERVE_STATIC_FILES'].present?

如果您已更新配置选项以使用public_file_server
,但仍看到过时警告,请按照Heroku的建议尝试从gem 'rails_12factor'
中删除Gemfile
。
