使用 Formtastic 分配嵌套属性
我已经尝试解决这个问题有一段时间了，但仍然没有运气。我有一个连接公司和人员的company_relationships表，存储一个额外的字段来描述称为“corp_credit_id”的关系的性质。我可以让表单正常工作来为人员添加 company_relationships，但我似乎无法弄清楚在这样做时如何设置该修饰符字段。有什么想法吗？
有关我的项目的更多信息：人们通过 company_relationships 拥有许多公司。有了这个额外的字段，我用它来将所有特定关系分组在一起。这样我就可以对一个人的医生、承包商等进行分组。
我的模型：
Company.rb（缩写）
class Company < ActiveRecord::Base
include ApplicationHelper
has_many :company_relationships
has_many :people, :through => :company_relationships
Person.rb（缩写）
class Person < ActiveRecord::Base
include ApplicationHelper
has_many :company_relationships
has_many :companies, :through => :company_relationships
accepts_nested_attributes_for :company_relationships
company_relationship.rb
class CompanyRelationship < ActiveRecord::Base
attr_accessible :company_id, :person_id, :corp_credits_id
belongs_to :company
belongs_to :person
belongs_to :corp_credits
end
我的表单部分，使用formtastic。
<% semantic_form_for @person do |f| %>
<%= f.error_messages %>
<% f.inputs do %>
...
<%= f.input :companies, :as => :check_boxes, :label => "Favorite Coffee Shops", :label_method => :name, :collection => Company.find(:all, :conditions => {:coffee_shop => 't'}, :order => "name ASC"), :required => false %>
所以我想做的是：corp_credit_id =>该输入中的“1”为咖啡店分配该属性。但 formattastic 似乎不允许这种分配发生。
关于如何做到这一点有什么想法吗？
I've been trying to figure this one out for a while but still no luck. I have a company_relationships table that joins Companies and People, storing an extra field to describe the nature of the relationship called 'corp_credit_id'. I can get the forms working fine to add company_relationships for a Person, but I can't seem to figure out how to set that modifier field when doing so. Any ideas?
More about my project: People have many companies through company_relationships. With that extra field in there I am using it to group all of the specific relationships together. So I can group a person's Doctors, Contractors, etc.
My models:
Company.rb (abridged)
class Company < ActiveRecord::Base
include ApplicationHelper
has_many :company_relationships
has_many :people, :through => :company_relationships
Person.rb (abridged)
class Person < ActiveRecord::Base
include ApplicationHelper
has_many :company_relationships
has_many :companies, :through => :company_relationships
accepts_nested_attributes_for :company_relationships
company_relationship.rb
class CompanyRelationship < ActiveRecord::Base
attr_accessible :company_id, :person_id, :corp_credits_id
belongs_to :company
belongs_to :person
belongs_to :corp_credits
end
My form partial, using formtastic.
<% semantic_form_for @person do |f| %>
<%= f.error_messages %>
<% f.inputs do %>
...
<%= f.input :companies, :as => :check_boxes, :label => "Favorite Coffee Shops", :label_method => :name, :collection => Company.find(:all, :conditions => {:coffee_shop => 't'}, :order => "name ASC"), :required => false %>
So what I would like to do is something like :corp_credit_id => '1' in that input to assign that attribute for Coffee Shop. But formtastic doesn't appear to allow this assignment to happen.
Any ideas on how to do this?
