Ruby on rails 嵌套设计模型形式

我正在使用Desive对用户进行身份验证，我希望在以相同的形式注册时为用户分配一个位置。我当前在提交表单时遇到此错误。有什么想法吗

ActiveRecord:：DeviceInvitable:：RegistrationController#create中的AssociationTypeMismatch

位置（#70224765161800）应为，已获得ActiveSupport:：HashWithInferenceAccess（#70224763369340）

我的位置模型

class Location < ActiveRecord::Base
 has_many :users, :dependent => :destroy
 accepts_nested_attributes_for :users, :allow_destroy => true
 attr_accessible :lat, :long, :name, :street_adress
 attr_accessible :user_attributes
end

用户/控制器

 def new
    @location = Location.new
    @location.user.build
    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @location }
    end
  end

  # GET /locations/1/edit
  def edit
    @location = Location.find(params[:id])
  end

  # POST /locations
  # POST /locations.json
  def create
    @location = Location.new(params[:location])

    respond_to do |format|
      if @location.save
        format.html { redirect_to @location, notice: 'Location was successfully created.' }
        format.json { render json: @location, status: :created, location: @location }
      else
        format.html { render action: "new" }
        format.json { render json: @location.errors, status: :unprocessable_entity }
      end
    end
  end

class UsersController < ApplicationController
  before_filter :authenticate_user!

  def index
    authorize! :index, @user, :message => 'Not authorized as an administrator.'
    @users = User.all
  end

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

  def update
   authorize! :update, @user, :message => 'Not authorized as an administrator.'
   @user = User.find(params[:id])
   if @user.update_attributes(params[:user], :as => :admin)
   redirect_to users_path, :notice => "User updated."
    else
   redirect_to users_path, :alert => "Unable to update user."
    end
  end

  def destroy
    authorize! :destroy, @user, :message => 'Not authorized as an administrator.'
    user = User.find(params[:id])
    unless user == current_user
      user.destroy
      redirect_to users_path, :notice => "User deleted."
    else
      redirect_to users_path, :notice => "Can't delete yourself."
    end
  end
end

class UsersController“未被授权为管理员。”
@users=User.all
结束
def秀
@user=user.find（参数[：id]）
结束
def更新
授权！：更新，@user，：message=>“未被授权为管理员。”
@user=user.find（参数[：id]）
如果@user.update_属性（参数[：user]，：as=>：admin）
将\重定向到用户\路径，：notice=>“用户已更新。”
其他的
将\重定向到用户\路径：警报=>“无法更新用户。”
结束
结束
def销毁
授权！：销毁，@user，：message=>“未被授权为管理员。”
user=user.find（参数[：id]）
除非用户==当前用户
用户破坏
将\重定向到用户\路径：notice=>“用户已删除。”
其他的
重定向到用户路径：注意=>“无法删除您自己。”
结束
结束
结束

您正在创建一个用户，因此User类应该具有accepts\u nested\u attributes\u for:location。但是我不确定它是否能解决问题…

您正在创建一个

用户

，因此

用户

类应该具有

接受嵌套的属性\u for:location

。但我不确定它是否能解决问题……谢谢@Baldrick，就是这样。
