ruby-on-rails - 在 Bootstrap 模式中渲染 Rails View

Question

我撞到了一堵砖墙。我已经解决这个问题很长时间了，我什至不确定我是如何到达我现在的位置的。我只能说，我已经尝试了以下所有方法，但均未成功:

How to add bootstrap modal with link_to so the link content open in modal ?

How to show twitter bootstrap modal via JS request in rails?

rails link_to :remote

如何在“索引” View 的 Bootstrap 模式中呈现"new"、“编辑”和“删除” View ，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"new"。当我单击“新建”按钮时，会出现一个带有字符串“<%= j render "items/new"%>"的模式(而不是该 ruby​​ 语句应该呈现的形式)。我究竟做错了什么？:

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

javascripts/items.js

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

Answer 1

例如，在 new 的情况下，您想要呈现一个 javascript 文件。为此，您需要创建 items/new.js.erb。

此外，从您的链接中删除 ", data: { toggle: "modal", target: "#newModal"}"，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

您不能直接在 View 上使用“渲染”，您应该渲染部分而不是 View (这就是我要求您将表单放入部分的原因)。
