Question

我让我的应用程序在本地运行。在部署期间，我遇到了几个问题：

首先，我为了部署而包装了关系对象，否则部署没有给出“标签”表错误

-- network protocol: Named Pipes
set quoted_identifier on
set arithabort off
set numeric_roundabort off
set ansi_warnings on
set ansi_padding on
set ansi_nulls on
set concat_null_yields_null on
set cursor_close_on_commit off
set implicit_transactions off
set language us_english
set dateformat mdy
set datefirst 7
set transaction isolation level serializable

然后我运行迁移并播种数据库。但是这一次，我没有资产工作，这让我意识到heroku在部署期间没有编译资产。

我更新了.gitignore以监督清单文件，以便heroku预先编译资产。但是这个操作给了我以下错误;

if ActiveRecord::Base.connection.table_exists? 'tags'
  filter :tags_keyword, :as => :check_boxes, :collection => Tag.all.collect {|o| [o.keyword, o.keyword]}
end

这是错误记录在AA gem文件夹

下的engine.rb文件

我在ubuntu 15.04上运行，使用ruby -v'2.2.2p95'，rails -v'4.2.1'并且有点担心该怎么做..我是一个菜鸟并想知道会出现什么问题？

Answer 1

我发现问题是我没有使用rails_12_factor gem并且使用折旧的rails环境变量玩过多。经过几次试验后，我设法回滚到默认设置，它运作良好！
