Rails 管理插件问题,针对同一模型的多对多关系
我一直在关注这篇文章中的第二个解决方案: Rails 中同一模型的多对多关系?
使用插件 Rails Admin (https: //github.com/sferik/rails_admin )
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
我能做什么有什么想法吗?
更新:
这是请求的错误:
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
Extracted source (around line #18):
15: <tbody>
16: <% @abstract_models.each do |abstract_model| %>
17: <tr class="<%= cycle 'odd', 'even' %>">
18: <td class="modelNameRow">
19: <%= link_to(RailsAdmin.config(abstract_model).list.label, rails_admin_list_path(:model_name => abstract_model.to_param), :class => "show") %>
20: </td>
21: <td>
I've been following the 2nd solutions on this post: Many-to-many relationship with the same model in rails?
While using the plugin Rails Admin ( https://github.com/sferik/rails_admin )
Using the code below, specifically seems to be breaking Rails Admin:
class PostConnection < ActiveRecord::Base
belongs_to :post_a, :class_name => :Post
belongs_to :post_b, :class_name => :Post
end
Any ideas for what I can do?
Update:
Here is the error as requested:

在模型的belongs_to语句中,尝试更改
:class_name =>; :Post
到:class_name => 'Post'
(字符串与符号)。我很确定这就是错误消息的相关内容。In your model's belongs_to statements, try changing
:class_name => :Post
to:class_name => 'Post'
(string vs symbol). I'm pretty sure that's what the error message is related to.
