【问题描述】：

我的 routes.rb 文件中有以下内容：

match "/service/:product"           => "products#show_name"
match "/products/custom/"           => "products#custom"
match "/products/customform"        => "products#customform"
match "/categories"                 => "products#categories"
match "/search"                     => "products#search"
match "/about"                      => "products#about"

get 'category/:tag', to: 'products#category', as: :tag

resources :products do
    resources :reviews
end

我正在尝试访问网址“/service/birchbox”。当我这样做时，我收到一个错误提示

No route matches {:action=>"edit", :controller=>"products"}

关于如何解决这个问题的任何建议？我试图让这个 url 转到列出的第一条路线（到控制器 products#show_name 但出于某种原因要编辑）。

这是我在控制台中看到的更多信息。似乎它会显示名称，但我不断收到错误消息。

Processing by ProductsController#show_name as HTML

【问题讨论】：

更改后是否重启了服务器？
@SergioTulentsev 是的，我做到了。我还用我收到的更多错误更新了问题。

【解决方案1】：

似乎在第 42 行的 views/products/show_name.html.erb 中有这样的内容：

<%= edit_product_path %>

而且这条路线不存在。 edit 路线需要产品 ID。试试这个：

<%= edit_product_path(@product) %>
