Question

我一直试图弄清楚这个错误大约3个小时，并找到了其他具有相同标题的示例，但是还没有找到任何解决方案..

该网站说：语法错误，意外的keyword_ensure，期待$ end，在/controllers/carts_controller.rb第17行

respond_to do |format|    ///////  <-- says here the problem

rails服务器说问题是：

views/carts/show.html.erb:21: syntax error, unexpected keyword_ensure, expecting $end

......这是整个代码：

/controllers/carts_controller.rb

class CartsController < ApplicationController
    def index
        @carts = Cart.all
        respond_to do |format|
            format.html # index.html.erb
            format.xml { render :xml => @carts }
        end
    end

    def show
        begin
            @cart = Cart.find(params[:id])
        rescue ActiveRecord::RecordNotFound
            logger.error "Attempt to access ionvalid cart #{params[:id]}"
            redirect_to store_url, :notice => 'Invalid cart'
        else
            respond_to do |format|
                format.html
                format.xml { render :xml => @cart }
            end
        end
    end
    def new
        @cart = Cart.new
        respond_to do |format|
            format.html
            format.xml { render :xml => @cart }
        end
    end

    def edit
        @cart = Cart.find(params[:id])
    end

    def create
        @cart = Cart.new(cart_params)
        respond_to do |format|
            if @cart.save
                format.html { redirect_to @cart, notice: 'Cart was successfully created.' }
                format.json { render action: 'show', status: :created, location: @cart }
            else
                format.html { render action: 'new' }
                format.json { render json: @cart.errors, status: :unprocessable_entity }
            end
        end
    end

    def update
        @cart = Cart.find(params[:id])
        respond_to do |format|
            if @cart.update_attributes(params[:cart])
                format.html { redirect_to(@cart, :notice => 'Cart was successfully updated.') }
                format.xml { head :ok }
            else
                format.html { render :action => "edit" }
                format.xml { render :xml => @cart.errors, :status => :unprocessable_entity }
            end
        end
    end

    def destroy
        @cart = current_cart
        @cart.destroy
        session[:cart_id] = nil
        respond_to do |format|
            format.html {redirect_to(store_url, :notice => 'Your cart is currently empty') }
            format.xml { head :ok }
        end
    end
end

缩进所有代码

观点：视图/推车/ show.html.erb

<div class="cart_title">Your Cart</div>
<table>
    <%= render(cart.line_items) %>
    <tr class="total_line">
        <td colspan="2">Total</td>
        <td class="total_cell"><%= number_to_currency(cart.total_price) %></td>
    </tr>
</table>
<%= button_to 'Empty cart', cart, :method => :delete, :confirm => 'Are you sure?' %>

解决方案：

问题出在 views / carts / show.html.erb 上。将购物车更改为 @cart 解决了问题。
