乙炔度：
教育：

user.education.name仅显示以下内容-教育：

不显示用户在其个人资料中使用以下选择选择的教育：

  <div class="element">
          Ethinicity:
          <%= best_in_place current_user, :ethnicity_id, :type => :select, collection: Ethnicity.all.map{|e| [e.id, e.name]}, :inner_class => 'education-edit', nil: 'Select Ethnicity' %>

乙炔度：
：select，collection:ocidentity.all.map{| e |[e.id，e.name]}，：internal_class=>'education edit'，nil:'select ocidentity'>
教育：
：select，collection:Education.all.map{| e |[e.id，e.name]}，：internal_class=>'Education edit'，nil:'select Education'>

我做错了什么？我如何才能让显示在他/她自己的个人资料中的用户教育显示在显示页面中

提前感谢

您缺少的

属于
关联，因为
有多个
和
有一个
关系。
属于_to
关联定义需要在其表具有外键的模型中定义

考虑到你的模型，尽管可以想象另一种方式，但我认为这些关联应该是这样的：

# User Model
class User < ActiveRecord::Base
  ...
  belongs_to  :ethnicity
  belongs_to  :education
end

# Ethnicity Model
class Ethinicity < ActiveRecord::Base
  attr_accessible :name
  has_many :users
end

# Education Model
class Education < ActiveRecord::Base
  attr_accessible :name
  has_many :users
end

#用户模型
类用户
如何将
用户
、
种族
和
教育
联系起来？你能发布你的模型吗？当然，请查看更新的帖子！
