【问题描述】:
我一直在关注这篇文章的第二个解决方案:Many-to-many relationship with the same model in rails?
在使用插件 Rails Admin (https://github.com/sferik/rails_admin)时
使用下面的代码,似乎特别破坏了 Rails Admin:
class PostConnection < ActiveRecord::Base
belongs_to :post_a, :class_name => :Post
belongs_to :post_b, :class_name => :Post
end
对我能做什么有什么想法吗?
更新:
这是所要求的错误:
NoMethodError in Rails_admin/main#index
Showing /Users/elliot/.rvm/gems/ruby-1.8.7-p299/bundler/gems/rails_admin-5713b1671e8c/app/views/rails_admin/main/index.html.erb where line #18 raised:
undefined method `match' for :Post:Symbol

"break" 不够详细。发布错误消息、堆栈跟踪等...
