ruby-on-rails - rails 凭据不获取

Question

我通过 rails credentials:edit 命令创建了 rails config/master.key 和 config/credentials.yml.enc

在 Rails 控制台上我能够获取值但是当我运行 rake db:migrate 时，我得到这个错误:

invalid port number: "Rails.application.credentials.development[:port]"
Couldn't create 'Rails.application.credentials.development[:database]' database. Please check your configuration.
rake aborted!
PG::ConnectionBad: invalid port number: "Rails.application.credentials.development[:port]"

看起来是语法上的问题

你需要像这样使用插值:

  database: <%= Rails.application.credentials.development[:database] %>
  username: <%= Rails.application.credentials.development[:username] %>
  password: <%= Rails.application.credentials.development[:password] %>
  host: <%= Rails.application.credentials.development[:host] %>
  port: <%=Rails.application.credentials.development[:port] %>
