Ruby on rails Rails-从关系中获取属性时遇到的问题

这些是我的模型：

class Person < ActiveRecord::Base
  has_many :honors, :dependent => :destroy, :foreign_key => "honored_id"
  has_many :honor_creators, :through => :honors, :source => :person, :foreign_key => "person_id"

class Group 
  has_many :honorss,:foreign_key => "group_id"

class Honor
  belongs_to :person, :class_name => 'Person', :foreign_key => "person_id"
  belongs_to :honored, :class_name => 'Person', :foreign_key => "honored_id"
  belongs_to :group, :class_name => 'Group', :foreign_key => "group_id"

我的看法是：

<% unless @honors.empty? %>
<% @honors.each do |ho| %>

我的问题是：使用

ho

我从

荣誉

中获取所有属性，但我想获取荣誉的创建者及其所属的组。我该怎么做

---

谢谢

您可以通过访问

ho.person

或

---

注意：

belongs_to :group, :class_name => 'Group', :foreign_key => "group_id"

及

将做同样的事情，因为当您给它

：group

时，Rails将假定该类和外键

要让

ho.honour\u creator

工作（如果我假设正确的话），您需要：

class Person < Model
  has_many :honors, :foreign_key => :creator_id
end

class Honor < Model
  belongs_to :creator, :class_name => "Person"
end

class Person < ActiveRecord::Base
  belongs_to :honor, :foreign_key => :recipient_id
  has_many :honors, :foreign_key => :creator_id

class Group 
  has_many :honors

class Honor
  has_many :recipients, :class_name => 'Person' # recipient_id is assumed
  belongs_to :creator, :class_name => 'Person' # creator_id is assumed
  belongs_to :group # group_id is assumed

我重新命名了一些专栏，希望能有更好的意义，这是我从头开始做的，所以我将查看一些参考资料以确保我的准确性

这将允许您访问

荣誉.creator

和

荣誉.group

<% @honors.each do |honor| %>
  Honor Creator: <%= honor.creator.name %>
  Honor Group: <%= honor.group.name %>
  Honor Recipients: <% honor.recipients.each {|recipient| puts recipient} %>
<% end %>

荣誉创造者：
荣誉团体：
获奖者：

可能弄乱了收件人协会，但我会去看看

class Person < Model
  has_many :honors, :foreign_key => :creator_id
end

class Honor < Model
  belongs_to :creator, :class_name => "Person"
end

class Person < ActiveRecord::Base
  belongs_to :honor, :foreign_key => :recipient_id
  has_many :honors, :foreign_key => :creator_id

class Group 
  has_many :honors

class Honor
  has_many :recipients, :class_name => 'Person' # recipient_id is assumed
  belongs_to :creator, :class_name => 'Person' # creator_id is assumed
  belongs_to :group # group_id is assumed

<% @honors.each do |honor| %>
  Honor Creator: <%= honor.creator.name %>
  Honor Group: <%= honor.group.name %>
  Honor Recipients: <% honor.recipients.each {|recipient| puts recipient} %>
<% end %>
