users_controller.rb
class ProfilesController user#show.html.erb
种族:<%= @[email protected] : "" %><div class="元素">教育:<span class="select_for_education"><%= @[email protected] : "" %>
user.education.name 仅显示以下内容 - 教育:
不显示使用以下选择在他的个人资料中选择的用户教育:
种族:<%= best_in_place current_user, :ethnicity_id, :type =>:select, 集合: Ethnicity.all.map{|e|[e.id, e.name]}, :inner_class =>'education-edit', nil: '选择种族' %><div class="元素">教育:<span class="select_for_education"><%= best_in_place current_user, :education_id, :type =>:选择，集合:Education.all.map{|e|[e.id, e.name]}, :inner_class =>'education-edit', nil: '选择教育'%>
我做错了什么?我怎样才能让用户在他/她自己的个人资料上显示的教育显示在显示页面中?
提前致谢！

职业种族education.rb
班级教育has_many 和 has_one 关系缺少 belongs_to 关联.belongs_to 关联定义需要在表具有外键的模型中定义.
鉴于您的模型，虽然可以想象相反的方式，但我认为关联应该如下所示:
# 用户模型类用户users_controller.rb
class ProfilesController < ApplicationController
before_filter :authenticate_user!
def show
@user = User.find(params[:id]) || User.find(current_user.id)
@questions_for_about = @user.questions.for_about.order('id asc')
@questions_for_personality = @user.questions.for_personality.order('id asc')
end
end
user#show.html.erb
<div class="element">
Ethinicity:
<%= @user.ethnicity.present? ? @user.ethnicity.name : "" %>
</div>
<div class="element">
Education:
<span class="select_for_education">
<%= @user.education.present? ? @user.education.name : "" %>
</div>
The user.education.name is just showing the following - Education:
Without showing the users Education in which was chosen on his personal profile using the following select:
<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' %>
</div>
<div class="element">
Education:
<span class="select_for_education">
<%= best_in_place current_user, :education_id, :type => :select, collection: Education.all.map{|e| [e.id, e.name]}, :inner_class => 'education-edit', nil: 'Select Education' %>
</div>
What am I doing wrong? And how can I get the users education that DOES display on his/her own profile to display in the show page?
Thanks in advanced!

解决方案 You're missing belongs_to association for has_many and has_one relation. The belongs_to association definition needs to be defined in the model whose table has the foreign key.
Given your models, although the other way around is imaginable, here is what I think the associations should look like:
# 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
