Question

我绝不是代码开发人员。我们的代码开发人员退出了，我刚刚获得了该项目。因此，我正在尝试学习代码，同时解决发生的问题。这是我目前面临的问题。我需要在两个不同的表中添加新列，我按照指示进行了三次单独的Active Record Migrations。当我尝试使用更新schema.rb时 $ rake db：migrate 我得到了以下内容。

[pcms -update to 4.4 (master)]$ rake db:migrate
WARNING: Nokogiri was built against LibXML version 2.9.2, but has         
dynamically loaded 2.8.0

PG::ConnectionBad: could not connect to server: Connection refused
     Is the server running on host "localhost" (::1) and accepting
     TCP/IP connections on port 5432?
could not connect to server: Connection refused
     Is the server running on host "localhost" (127.0.0.1) and accepting

 Tasks: TOP => db:migrate
 (See full trace by running task with --trace)

的database.yml

development:
  adapter: postgresql
  database: pcms_development
  host: localhost

test:
  adapter: postgresql
  database: pcms_test
  host: localhost

耙迁移不起作用
