Question

如何使用任何编辑gems par例如：best_in_place来编辑has_one和/ has_many关系中子模型的属性。

示例:(只是一个示例，不是实际问题;用于解释。）用户模型有许多目标（目标模型），每个目标都有一些属性。如何使用gem“best_in_place”从显示页面编辑这些属性。

在Railscast http://railscasts.com/episodes/302-in-place-editing上的“就地编辑”中将其视为显示，但最终出现"undefined method :property for goal"等错误，同时在模型类的现场尝试@user.goal为否果。

实际上代码可以在下面看到。

我实际上是用它来编辑用户的个人资料属性，但是类似的概念和错误......

User.rb

class User < ActiveRecored::Base
   has_one :profile, dependent: :destroy
   after_create :build_profile

   accepts_nested_attributes_for :profile
   attr_accessible :email, :password, :password_confirmation, :profile_attributes

   def build_profile
     Profile.create(user_id: self.id)
   end
end

Profile.rb

 class Profile < ActiveRecord::Base
   attr_accessible :name. :address, :age
   belongs_to :user

   validates :name, presence: true, length: { maximum: 50 }
   validates :address, :age,  presence: true
 end

Users_controller.rb

class UsersController < ApplicationController
  def new
    @user = User.new
    @profile = self.build_profile 
  end

  def create
    @user = User.new(params[:user])
    if @user.save 
      sign_in @user
      flash[:success] = "welcome, Thanks for Signing up"
      redirect_to @user
    else
      render 'new'
    end
 end

end

Profiles_controller.rb

class ProfilesController < ApplicationController

 def edit 
   @profile = Profile.find(params[:id])
 end

 def update
   @profile = Profile.find(params[:id])
   if @profile.update_attributes(params[:profile])
     flash[:success] = "Profile Updated"
     redirect_to @user
   else
     render 'edit'
   end
 end

 def show 
   @user.profile = User.find(params[:id]).profile
 end

 def destroy
 end
end

用户/ show.html.erb

<% provide(:title, "Profile" ) %>
<h1><%= @user.profile.name %></h1>

<p>
  <b> Address  </b> <%= best_in_place @profile, :address, :path => user_profile_path(@user, @profile) %>
</p>

数据库表（使用User_id作为外键）

USER TABLE                                                PROFILE TABLE
 ------------------------                                 ------------------------

您需要向update

添加profiles_controller操作

类似的东西：

def update
  @profile = Profile.find params[:id]

  respond_to do |format|
    if @profile.update_attributes(params[:profile])
      format.json { respond_with_bip(@profile) }
    end
  end
end

编辑到一个有一个关系
