Rails无法在生产中解析数据库URL

本文介绍了Rails无法在生产中解析数据库URL的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有以下database.yml文件：

I have the following database.yml file:

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'] %>

，我在生产中有一个DATABASE_URL，类似于 postgresql：// user： passwrd@backoffice.xxxxxxxx.xxxxx.rds.amazonaws/backoffice_api

and I have a DATABASE_URL on production similar to postgresql://user:passwrd@backoffice.xxxxxxxx.xxxxx.rds.amazonaws/backoffice_api

当我尝试在生产环境中启动应用程序时出现此错误：

when I try start my app on production I get this error:

2017-06-12T08:23:37.054417906Z Initialising & migrating DB 2017-06-12T08:23:38.381585952Z rake aborted! 2017-06-12T08:23:38.381700163Z URI::InvalidURIError: bad URI(is not URI?): 'postgresql://user:passwrd@backoffice.xxxxxxxx.xxxxx.rds.amazonaws/backoffice_api'

以及其他一些例外行之后：

and after some other exception lines:

我显然不是在使用MySQL，如果在我的机器上使用该URL，它将起作用！

I'm obviously not using MySQL and if use that URL on my machine, it works! what could be wrong?

推荐答案

尝试

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