我一直在寻找一段时间，似乎无法弄清楚是什么造成这种情况，我有一个模型工作节省志愿者和他的家庭和工作地址。我改变了一些东西（似乎无法弄清楚我的生活），现在地址没有被设置。错误的订单保存模型导轨
这是我的主要型号：
class HumanVolunteer < ActiveRecord::Base
has_one :primaryPhone, :class_name => "PhoneNumber", :foreign_key => "id", :primary_key => "phone_id"
has_one :primaryEmail, :class_name => "Email", :foreign_key => "id", :primary_key => "email_id"
has_one :work_adr, :class_name => "Address", :foreign_key => "id", :primary_key => "workaddressid"
has_one :home_adr, :class_name => "Address", :foreign_key => "id", :primary_key => "homeaddressid"
attr_accessible :firstName, :lastName, :homeaddressid, :notes, :status, :workaddressid, :home_adr, :work_adr,
:primaryPhone, :primaryEmail, :home_adr_attributes, :work_adr_attributes, :primaryPhone_attributes,
:primaryEmail_attributes
accepts_nested_attributes_for :home_adr
accepts_nested_attributes_for :work_adr
accepts_nested_attributes_for :primaryPhone
accepts_nested_attributes_for :primaryEmail
end
和地址型号：
class Address < ActiveRecord::Base
attr_accessible :city, :line1, :line2, :notes, :state, :zipcode
belongs_to :human_volunteer
end
继承人从human_volunteers_controller片段
# GET /human_volunteers/new
# GET /human_volunteers/new.json
def new
@human_volunteer = HumanVolunteer.new
@human_volunteer.build_home_adr
@human_volunteer.build_work_adr
@human_volunteer.build_primaryPhone
@human_volunteer.build_primaryEmail
# Set the Breadcrumbs for this page
@breadcrumbs = { "Dashboard" => "/", "Human Volunteers" => "/human_volunteers"}
@current_page = "New Volunteer"
respond_to do |format|
format.html # new.html.erb
format.json { render :json => @human_volunteer }
end
end
# GET /human_volunteers/1/edit
def edit
@human_volunteer = HumanVolunteer.find(params[:id])
if(@human_volunteer.home_adr.nil?)
@human_volunteer.build_home_adr
end
if(@human_volunteer.work_adr.nil?)
@human_volunteer.build_work_adr
end
if(@human_volunteer.primaryPhone.nil?)
@human_volunteer.build_primaryPhone
end
if(@human_volunteer.primaryEmail.nil?)
@human_volunteer.build_primaryEmail
end
@breadcrumbs = { "Dashboard" => "/", "Human Volunteers" => "/human_volunteers"}
@current_page = "Edit Volunteer: <em>" + @human_volunteer.firstName + " " + @human_volunteer.lastName + "</em>";
end
# POST /human_volunteers
# POST /human_volunteers.json
def create
# create the volunteer
@human_volunteer = HumanVolunteer.new(params[:human_volunteer])
respond_to do |format|
if @human_volunteer.save
format.html { redirect_to @human_volunteer, :notice => @human_volunteer.firstName + ' ' + @human_volunteer.lastName + ' was successfully created.' }

else
format.html { render :action => "new" }
format.json { render :json => @human_volunteer.errors, :status => :unprocessable_entity }
end
end
end
# PUT /human_volunteers/1
# PUT /human_volunteers/1.json
def update
@human_volunteer = HumanVolunteer.find(params[:id])
respond_to do |format|
if @human_volunteer.update_attributes(params[:human_volunteer])
format.html { redirect_to @human_volunteer, :notice => @human_volunteer.firstName + ' ' + @human_volunteer.lastName + ' was successfully updated.' }
format.json { head :no_content }
else
format.html { render :action => "edit" }
format.json { render :json => @human_volunteer.errors, :status => :unprocessable_entity }
end
end
end
我可以看到什么我认为这个问题通过查看日志，人类志愿者首先得到保存，使用地址码的空值s，然后地址被保存（也与电话号码和电子邮件模型相同的问题，它们与地址设置相同），然后地址被保存，然后人类志愿者不会再次用新值更新：

我能回头到日志中，找到一个工作，而human_volunteer是最后一件事插入。它首先插入地址，电子邮件，电话，然后在插入志愿者时使用这些ID。
编辑：我也可以报告，我没有得到任何错误，一切都经过，只是数据没有连接。
任何想法可能导致订单的变化？我看不到我改变了任何影响这一点的事情。
更新：我试图改变HAS_ONE线和能够至少产生一个错误（更好或更差），当我cahnged行到：
has_one :workaddress, :class_name => "Address", :foreign_key => "id", :primary_key => "workaddress"
has_one :homeaddress, :class_name => "Address", :foreign_key => "id", :primary_key => "homeaddress"
它尝试使用addressid 1每次我也得到
ActiveRecord::RecordNotUnique (PG::Error: ERROR: duplicate key value violates unique constraint "addresses_pkey"
DETAIL: Key (id)=(1) already exists.
另外，如果我拿出primary_key领域，似乎工作，但它试图将它们均设置为相同的地址，我也得到了同样的错误，除了与下一个ID（22，23 ，每次我尝试24次等）
也许这可以解释一些问题？我会继续刺激。
非常感谢你， - 肯
你不能在你的提交历史看看，看看你修改了什么？ – 2012-08-07 17:05:45
我不确定导轨如何使用NameCasing破坏名称，但不应该* belongs_to：human_volunteer * be * belongs_to：humanvolunteer *？ – 2012-08-07 17:09:14
嘿谢谢你的回复，我试过使用：humanvolunteer，而不是运气。我还没有开始使用版本控制（只是在工作的早期阶段），所以我没有任何方式回滚。 – 2012-08-07 17:54:34
