在Bootstrap模式中渲染Rails视图

我打了一堵砖墙。我一直在讨论这个问题很久了,我甚至不确定我是怎么到达的。我只能说,我已经尝试了以下所有方面但没有成功:

如何在“索引”视图中的Bootstrap模式中呈现“新”,“编辑”和“删除”视图,而不是链接到每个单独的页面?

这是我现在的代码。现在,让我们忽略“编辑”和“删除”,只关注“新”。当我单击“新建”按钮时,一个带有字符串“<%= j render”items / new“%>”的模态出现(而不是该ruby语句应呈现的形式)。我做错了什么?:

items_controller.rb:

class ItemsController < ApplicationController

  def index
    @items = Item.all
  end

  def new
    respond_to do |format|
      format.js {}
    end
  end

  def create
    @item = Item.new(item_params)
    if @item.save
      flash[:notice] = "'#{@item.name}' saved!"
      redirect_to items_path
    else
      flash[:notice] = "Something went wrong :("
      render "index"
    end
  end

  def edit
    @item = Item.find(params[:id])
    respond_to do |format|
      format.js {}
    end
  end

  def update
    @item = Item.find(item_params[:id])
    if @item.update_attributes(item_params)
      flash[:notice] = "Successfully updated #{@item.name}."
      redirect_to items_path
    else
      flash[:notice] = "Oops"
      # render "edit"
    end
  end

  private
    def item_params
      params.require(:item).permit(:name, :bid, :uuid)
    end

end

Javascript角/ items.js

$(document).on("page:change", function() {
  $("#newModal .modal-content").html('<%= j render "items/new" %>');
});

例如,在新的情况下,您想要渲染一个javascript文件。为此,您需要创建items / new.js.erb。

此外,删除&#34;,数据:{toggle:&#34; modal&#34;,target:&#34; #newModal&#34; }&#34;从您的链接,我们将在javascript中执行此操作。

  # new.js.erb
  $("#newModal .modal-content").html('<%= j render "items/form" %>');
  $("#newModal").modal(); // Or whatever the Bootstrap function is to render the modal


  # items/_form.html.slim
  # Here you'll put your form

你不能使用&#34;渲染&#34;直接在视图上,你应该渲染局部而不是视图(这就是为什么我要求你把你的形式变成局部的)。

我把它扔在一起,加载后3秒钟我的文档中放了一个大的'3':

<script>
setTimeout(function() {
    $("#holder").html("<%= j render(:file => 'things/test.html.erb') %>");
}, 3000);
</script>
<div id="holder></div>

应用/视图/东西/ test.html.erb

<h1><%= 1 + 2 %></h1>

这应该让你去。
