Question

我对昨天将代码推送到生产后收到的新错误感到难过。我没有编辑文件中的任何内容，它仍可在我的本地计算机上正常工作。这段代码已经好几个月了。任何见解都将不胜感激。

日志错误：

Answer 1

“没有救援的其他东西是没用的”，因为“如果你有一个畸形”，那就是红宝石。在这种情况下，看起来就像是在调用simple_form_for时，在错误的地方有parens。我之前没有使用过simple_form_for，但这就是错误。或完全离开parens。

<%= simple_form_for ([type, @line_item], remote: true) do |f| %>

仅在生产中被语法错误所困扰
