javascript - 在模态中使用新表单渲染页面，而不是在 Ruby on Rails/JS 中使用新页面

Question

我无法渲染( Bootstrap )模式，而不是渲染用于创建新房间的经典 new.html.erb 。

鉴于我是 JS 和模态的新手，我感觉我对正确阅读/理解在线该主题的内容并随后解决我的问题所需的一些基本概念缺乏了解。 因此，我想知道是否有人可以帮助我在创建模态时更好地理解代码中正在发生(和未发生)的事情。

真的很抱歉创建这么长的问题，但我不知道如何解释它，因为我不确定在哪里查看/错误在哪里(这甚至包括文件夹映射)。

Assets /javascripts/application.js

//= require jquery
//= require popper
//= require bootstrap
//= require_tree .

gem 文件

gem 'bootstrap'
gem 'popper_js'
gem 'jquery-rails'

型号

class Room < ApplicationRecord
  belongs_to :hotel
end

class Hotel < ApplicationRecord
  has_many :rooms, dependent: :destroy
end

Controller

class RoomsController < ApplicationController

  def new
    respond_to do |format|
      format.html
      format.js
    end
    @hotel = Hotel.find(params[:hotel_id])
    @room = Room.new
    authorize @room
  end

  def create
    @room = Room.new(room_params)
    @hotel = Hotel.find(params[:hotel_id])
    @room.hotel = @hotel
    authorize @room

    #redirect to index page
    if @room.save
      redirect_to hotel_rooms_path(@hotel)
    else
      render :new
    end
  end

views/rooms/index.html.erb

<%= render "partials/show_panel_rooms_overview"%>

下面是我的代码渲染，其中 link_to 引用了 Rails 的传统新 View (工作)

views/partials/_show_panel_rooms_overview.html.erb

<%= link_to "add new room", new_hotel_room_path, class: "new-room-btn" %>

views/rooms/new.html.erb

<%= render 'room_new_form', hotel: @hotel%>

views/rooms/_room_new_form.html.erb

<%= simple_form_for [@hotel, @room] do |f|%>
    <%= f.input :name %>
    <%= f.button :submit %>
<% end %>

模态代码下方(不起作用)

(i) 模型 + (ii) Controller 同上

views/partials/_show_panel_rooms_overview.html.erb

<%= link_to "add new room", new_hotel_room_path,  {:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'}  %>
<div id="modal-window" class="modal hide fade" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>

views/rooms/new.html.erb

<div class="modal-header">
   <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
   <h3 id="myModalLabel">Modal header</h3>
 </div>
 <div class="modal-body">

<%= render 'room_new_form', hotel: @hotel%>

 </div>
 <div class="modal-footer">
   <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
   <button class="btn btn-primary">Save changes</button>
 </div>

views/rooms/_room_new_form.html.erb

<%= simple_form_for [@hotel, @room] do |f|%>
    <%= f.input :name %>
    <%= f.button :submit %>
<% end %>

views/rooms/_new.js.erb

$("#modal-window").html("<%= escape_javascript(render 'rooms/new') %>");

对于查看我的问题的人，如果您可能会觉得有趣，我更进一步(例如下一个错误)。呈现新表单的关键是使用 new.js.erb 并因此引用 partial 而不是 new.html.erb。 如果您对我当前的错误消息/代码有任何进一步的意见，请告诉我。

views/partials/_show_panel_rooms_overview.html.erb

<%= link_to "New", new_hotel_room_path, remote: true, class: "btn btn-success pull-right new" %>

views/rooms/new.js.erb

 $("#newModal .modal-content").html('<%= j render "rooms/room_new_form" %>');
  $("#newModal").modal();

views/rooms/_room_new_form.html.erb

<div class="modal-header">
  <button type="button" class="close" data-dismiss="modal"><span>&times;</span></button>
  <h4 class="modal-title">New Item</h4>
</div>
<div class="modal-body">
<%= simple_form_for [@hotel, @room] do |f|%>
    <%= f.input :name %>
    <%= f.button :submit %>
<% end %>
</div>

这给我带来了一个新的(耶)错误:

View 是根据我的终端渲染的，但没有显示任何内容:

Rendering rooms/new.js.erb
  Rendered rooms/_rooms_new_form.html.erb (9.2ms)
  Rendered rooms/new.js.erb (13.2ms)
Completed 200 OK in 35ms (Views: 28.4ms | ActiveRecord: 0.4ms)
