SQLException：“参考”附近：语法错误：ALTER TABLE“问题”添加“视频”参考答案

【问题标题】：SQLException: near "references": syntax error: ALTER TABLE "questions" ADD "video" referencesSQLException：“参考”附近：语法错误：ALTER TABLE“问题”添加“视频”参考
【发布时间】：2013-08-14 18:04:06
【问题描述】：

我试过“AddvideoToQuestions video: references"

一个问题有_many 个视频。一个视频属于一个问题。

试图耙db:migrate，并得到以下错误。

怎么样？我终于深入研究 Rails 编码（我的第一种真正的语言），这个错误一直困扰着我。

SQLite3::SQLException: 在“引用”附近：语法错误：ALTER TABLE “问题”添加“视频” 参考资料/Users/davidngo/.rvm/gems/ruby-1.9.3-p429/gems/sqlite3-1.3.7/lib/sqlite3/database.rb:91:in `初始化'

@Marek Lipka -- 尝试过并再次尝试 rake db:migrate，但仍然是同样的错误。

以下是日志：

【解决方案1】：

试试这个：

bundle exec rails g migration add_video_to_questions video:references

【解决方案2】：

我相信这已经得到了回答： Rails 3 migrations: Adding reference column?

话虽如此，我也遇到了类似的问题。我无法告诉你到底出了什么问题，但这是我解决问题的方法：

rails g 迁移 add_video_id_to_questions video_id:integer
