用于创建方法 smart_listing 的 Rails 嵌套路由

Question

我有两个模型：公寓和房间。公寓有_很多房间，房间属于_公寓。我使用 smart_listing gem 作为 ajax 形式。我在 edit_apartment_path 中显示我的表

= render 'rooms/index' # index is partial

然后我将它添加到我的 apartment_controller

def edit
    @rooms = smart_listing_create :rooms,
                                      Room.where(apartment_id: params[:apartment_id]),
                                      partial: "rooms/list"
end

现在我必须为我的表单设置路径

= simple_form_for object, url: object.new_record? ? apartment_rooms_path : apartment_room_path(id: object),
                   remote: true, html: {class: "form-horizontal"} do |f|
  = f.input :title
  = f.button :submit

我可以编辑我创建的房间，但我不能在公寓中创建新房间。我的错误：

ActionController::UrlGenerationError - No route matches {:action=>"edit", :apartment_id=>nil, :controller=>"rooms", :id=>#<Room id: 83, title: "dawawd">, created_at: "2016-02-11 10:36:30", updated_at: "2016-02-11 10:36:30", apartment_id: 4>} missing required keys: [:apartment_id]:

我的路线

resources :apartments do
      resources :rooms
    end

可能 smart_listing 不支持嵌套路由。有人知道吗？ :)

Answer 1

这里是带有 smart_listing 的嵌套路由的简单示例。我认为这应该涵盖这个主题。 我用过Rails 4.2，ruby 2.2.0，smart_listing 1.1.2

config/routes.rb

resources :users do
  resources :bios
end
root 'users#index'

models/user.rb

class User < ActiveRecord::Base
  has_one :bio
  accepts_nested_attributes_for :bio, allow_destroy: true
  scope :like, ->(args) { where("email like '%#{args}%' OR name like '%#{args}%' OR surname like '%#{args}%'")}
end

models/bio.rb

class Bio < ActiveRecord::Base
  belongs_to :user
end

controllers/users_controller.rb

class UsersController < ApplicationController
  include SmartListing::Helper::ControllerExtensions
  helper  SmartListing::Helper
  before_action :set_user, only: [:update, :destroy]

  def index
    users_scope = User.all.includes(:bio)
    users_scope = users_scope.like(params[:filter]) if params[:filter]
    # @users = smart_listing_create :users, users_scope, partial: "users/list", page_sizes: [5, 7, 13, 26]
    @users = smart_listing_create(:users, users_scope, partial: 'users/list',
                               sort_attributes: [
                                [:name, 'name'],
                                [:surname, 'surname'],
                                [:email, 'email'],
                                [:city, 'bio.city'],
                                [:birthday, 'bio.birthday']
                               ],
                               default_sort: { start_at: 'desc' }
                               )
  end

  def new
    @user = User.new
    @user.build_bio
  end

  def create
    @user = User.new(user_params)
    @user.save
  end

  def edit
    @user = User.includes(:bio).find(params[:id])
    @user.bio.build if @user.bio.nil?
  end

  def update
    @user.update(user_params)
  end

  def delete
  end

  def destroy
    @user.destroy
  end

  private

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

  def user_params
    params.require(:user).permit(:name, :surname, :email, :bio_attributes => [:birthday, :city])
  end
end

Answer 2

您也应该收到@apartment 的表单，在这种情况下，如果您的@room.persisted? 表单收到编辑请求，否则创建：

= simple_form_for [@apartment, @room], remote: true, html: {class: "form-horizontal"} do |f|
  = f.input :title
  = f.button :submit
