Rails 3,使用mongoid但会产生语法错误

Question

在我的开发环境中,即Windows 7,Ruby1.9.2p180,一切正常.

但是,在生产环境中,即使用rvm的Ubuntu 10.04,Ree 1.8.7,会产生以下错误.(我正在使用passenger-apache-module来运行应用程序.)

/home/randomapp/public_html/app/models/article.rb:14: syntax error, unexpected ':', expecting kEND field :user_id, type: Hash ^ 
/home/randomapp/public_html/app/models/article.rb:15: syntax error, unexpected ':', expecting kEND field :username, type: String ^ 
/home/randomapp/public_html/app/models/article.rb:16: syntax error, unexpected ':', expecting kEND field :title, type: String ^ 
/home/randomapp/public_html/app/models/article.rb:17: syntax error, unexpected ':', expecting kEND field :content, type: String ^ 
/home/randomapp/public_html/app/models/article.rb:18: syntax error, unexpected ':', expecting kEND field :display_content, type: String ^ 

这些行的代码如下

  field :user_id, type: Hash
  field :username, type: String
  field :title, type: String
  field :content, type: String
  field :display_content, type: String

假设上面的行在开发中工作正常,你认为它可能是语法解析器的问题吗？我该如何解决这个问题？

Answer 1

您正在使用1.9.2哈希语法.如果你想在1.9.2和1.8.7上运行,那么试试这个:

field :user_id, :type => Hash
field :username, :type => String
field :title, :type => String
field :content, :type => String
field :display_content, :type => String
