Ruby on Rails未定义的方法`products_path'路由问题

我已经在Rails工作了一段时间，并且在正确设置路由时遇到了一些问题。任何帮助将不胜感激。Ruby on Rails未定义的方法`products_path'路由问题

URL: http://localhost:3000/admin/products/new 

Error: undefined method `products_path' for #<#<Class:0x007f9f569d0150>:0x007f9f578ccb18>

耙路由

运行'耙routes'看到所有路由。其实，路由应该像'admin_products_path'，因为你有'：admin'命名空间 –

Sergey，运行耙路由给我下面： new_admin_product GET /admin/products/new(.:format）admin/products＃new –

如果你看到你有'admin_products'。这就是你需要的。用'<％= link_to“管理产品试试iy，”admin_products_path％>' –

因为你在URL: http://localhost:3000/admin/products/new错误，所以你应该有一些与你的表单生成器的问题。

虽然在:admin名称空间中有产品资源，但在构建表单时应考虑到这一事实。正确的例子是：

<%= form_for [:admin, @product] do |f| %> 
    ... # whatever 
<% end %>

，而不是仅仅

<%= form_for @product do |f| %> 
    ... # whatever 
<% end %>

哇。现在我甚至不知道。我不能够感谢你！我已经提出了答案，并在应有的地方给予奖励。再次感谢！！！！ –

我很乐意帮助您 –

您可能还需要'，url：admin_product_path（resource）'' –

某处在您的新模板您呼叫products_path。由于它是在管理你应该将其更改为admin_products_path
