Ruby on rails 集合中的第一个项目没有'；t提交行动[已编辑],ruby-on-rails,ajax,Ruby On Rails,Ajax,我有两个控制器，它们修改一个大视图（carts/new.html.erb）。此视图呈现order_item/new.html.erb，作为搜索结果传递@products的每个产品。此函数工作正常。但是，当我单击为每个产品创建的表单的submit按钮时，这不起作用（仅适用于第一个产品），对于其他产品，它可以正常工作。因此，我看到生成的html，第一个表单标记没有生成缺少标签 <form accept-charset="UTF-8" action="/order_items" class="

您的日志显示了两个非常不同的操作。打破一个与提交您的订单项目表单无关-它与创建一个新购物车有关

CartsController#new

它正在崩溃，因为您尚未将

product

作为变量传递到Carts/new.js.erb中-订单项目控制器如何运行到Carts控制器？好的，我能做什么？我不明白这在其他产品中是如何工作的。问题（在日志中很清楚）是在

CartsController#new

操作中没有设置名为

product

的变量，但模板

app/views/carts/new.js.erb

（将由该操作呈现）显然，我们希望有一个

产品

变量。我不知道你希望这个行动何时以何种方式进行。。。但这是你的问题-现在你必须弄清楚是否需要设置该变量，或者更改模板以执行其他操作。我知道new.js.erb并不是什么都不做。所以我删除了那个文件。现在，当我单击第一个产品时，日志只显示没有错误的第二个操作：Started GET“/orders？utf8=%E2%9C%93&search=&utf8=%E2%9C%93&authenticity\u-token=7pM8PRU8Uy4euEtSv%2fgzyhjrpewdiiazxdp5xnd9u0%3D&order\u-item%5Bquantity%5D=3&order\u-item%5Bproduct%5Bproduct\id%5D=2&commit=Agregar+a+la+orden”对于2015-03-10 02:19:29-0300时的127.0.0.1，CartsController的处理（新为HTML1）注释中的代码格式非常糟糕=请将所有代码放入原始问题2），这看起来只是stacktrace的起始行。。。其余的也很重要。
