Rails ActionView::TemplateError（shop_url 无法从

Question

我收到了，但我没有更改任何这些代码。我的开发环境运行良好。这发生在生产环境中。

当有匹配的条目时会发生这种情况。当没有匹配的条目时，没关系（显然！）。

当我的type 是其他garages、malls 等时，它们都运行良好。我什至重建了我的 Thinking Sphinx 索引。

更新 原来 MySQL ID 从 1、2、3 自动递增...我删除了 1、2、3 条目并将 ID 替换为 200000、200001、200002，这给了我问题。不知道 Rails 这么严格。

从错误消息中非常清楚。 :type => "places" 让你很伤心。如果您确实打算传递给控制器​​，您可能需要将 "?type=places 固定到生成的 URL 的末尾。
