管理命名空间，嵌套资源不保存

我在管理命名空间中创建嵌套资源时遇到问题。 我对命名空间有些新意。 我已经阅读了Stack上的几篇文章，但无济于事，也许我正在实现这个错误。

我有一个管理模型（设计），我试图将地址嵌套到我创建的自定义用户显示页面，这就是问题所在。

在尝试为管理员创建新地址时，我在提交表单时收到此错误：

ActionController::UrlGenerationError at /admin/admins/2CE0/addresses No route matches {:action=>"show", :admin_id=>"2CE0", :controller=>"admin/admins/admin/addresses"} missing required keys: [:id] 

更好的错误页面的屏幕截图：

我的Routes.rb

  namespace :admin do devise_for :admins, controllers: { sessions: 'admin/admins/sessions', passwords: 'admin/admins/passwords', registrations: 'admin/admins/registrations', confirmations: 'admin/admins/confirmations', unlocks: 'admin/admins/unlocks', shared: 'admin/admins/shared' } resources :admins, controller: 'admins/admin', shallow: true do resources :addresses, except: [:index], controller: 'admins/admin/addresses' end end ###Admin Authentication Scope### devise_scope :admin do authenticated do root to: 'admin/admin_static#home', as: 'authenticated_admin' end end 

耙路输出：

  admin_admin_addresses POST /admin/admins/:admin_id/addresses(.:format) admin/admins/admin/addresses#create new_admin_admin_address GET /admin/admins/:admin_id/addresses/new(.:format) admin/admins/admin/addresses#new edit_admin_address GET /admin/addresses/:id/edit(.:format) admin/admins/admin/addresses#edit admin_address GET /admin/addresses/:id(.:format) admin/admins/admin/addresses#show PATCH /admin/addresses/:id(.:format) admin/admins/admin/addresses#update PUT /admin/addresses/:id(.:format) admin/admins/admin/addresses#update DELETE /admin/addresses/:id(.:format) admin/admins/admin/addresses#destroy 

管理员模型：

 class Admin < ActiveRecord::Base before_create :generate_admin_ident # Devise Modules devise :database_authenticatable, :registerable,:recoverable, :rememberable, :trackable, :validatable, :confirmable, :lockable, :timeoutable # Model Relationships has_many :addresses, dependent: :destroy # Model Validations validates_uniqueness_of :admin_ident #Unique Identifier Generation def generate_admin_ident begin self.admin_ident = SecureRandom.hex(2).upcase other_admin = Admin.find_by(admin_ident: self.admin_ident) end while other_admin end # Vanity URL def to_param admin_ident end end 

管理员控制器： – 请注意，这仅控制自定义管理员索引和显示页面

 class Admin::Admins::AdminController < ApplicationController before_action :authenticate_admin_admin! def index @admins = Admin.all end def show @admin = Admin.find_by_admin_ident(params[:id]) @addresses = @admin.addresses end def new end def edit end def create end def update end def destroy end end 

地址模型：

 class Address < ActiveRecord::Base before_create :generate_address_ident # Model Relationships belongs_to :admin # Model Validations validates_uniqueness_of :address_ident #Unique Identifier Generation def generate_address_ident begin self.address_ident = SecureRandom.hex(4).upcase other_address = Address.find_by(address_ident: self.address_ident) end while other_address end # Vanity URL def to_param address_ident end end 

地址控制器：

 class Admin::Admins::Admin::AddressesController < ApplicationController before_action :authenticate_admin_admin! before_action :set_address, only: [:show, :edit, :update, :destroy] # GET /addresses # GET /addresses.json def index @addresses = Address.all end # GET /addresses/1 # GET /addresses/1.json def show end # GET /addresses/new def new @admin = Admin.find(params[:admin_id]) @address = Address.new end # GET /addresses/1/edit def edit end # POST /addresses # POST /addresses.json def create @admin = Admin.find_by_id(params[:admin_id]) @address = Address.new(address_params) respond_to do |format| if @address.save format.html { redirect_to admin_admin_address_url[:admin, @admins, @address], notice: 'Address was successfully created.' } format.json { render :show, status: :created, location: @address } else format.html { render :new } format.json { render json: @address.errors, status: :unprocessable_entity } end end end # PATCH/PUT /addresses/1 # PATCH/PUT /addresses/1.json def update respond_to do |format| if @address.update(address_params) format.html { redirect_to @address, notice: 'Address was successfully updated.' } format.json { render :show, status: :ok, location: @address } else format.html { render :edit } format.json { render json: @address.errors, status: :unprocessable_entity } end end end # DELETE /addresses/1 # DELETE /addresses/1.json def destroy @address.destroy respond_to do |format| format.html { redirect_to addresses_url, notice: 'Address was successfully destroyed.' } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_address @address = Address.find_by_address_ident(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def address_params params.require(:address).permit(:admin_id, :street_number, :street_name, :street_type, :grid, :city, :province, :postal_code, :current) end end 

最后，在尝试创建新的管理地址时，Rails Server Console输出：

提前谢谢大家，我在这里遇到困难，不知道我从哪里跌落兔子洞！ 请询问您是否需要更多信息，我尽量提供！

如果您不熟悉名称间距，我建议您创建一个新的应用程序，然后使用脚手架生成器在管理员名称空间中创建一个地址。 然后看看脚手架构建对象的方式，并将其与您拥有的对象进行比较。

 rails new name_space_play cd name_space_play rails g scaffold Admin::Address street_number street_name street_type grid city province postal_code current 

Scaffold将以rails开发人员期望构建它们的方式构建文件，并且应该向您展示如何执行它们。
