Question

我有以下database.yml文件：

default: &default
  adapter: postgresql
  encoding: unicode
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 4 } %>

development:
  <<: *default
  database: backoffice_authentication_development

test:
  <<: *default
  database: backoffice_authentication_test

production:
  <<: *default
  url: <%= ENV['DATABASE_URL'] %>

我生产的DATABASE_URL类似于postgresql://user:passwrd@backoffice.xxxxxxxx.xxxxx.rds.amazonaws.com/backoffice_api

当我尝试在制作时启动我的应用时，我收到此错误：

并在其他一些例外行之后：

我显然没有使用MySQL，如果在我的机器上使用该URL，它可以工作！什么可能是错的？

Answer 1

尝试

url: <%= URI.encode(ENV['DATABASE_URL'] )%>

Rails在生产时不解析数据库URL
