所以我正在做一个项目，我想创建新的子类别。该链接有效，但我没有收到以下错误：

没有路线匹配 {:action=>"show", :controller=>"subcategories"}

该项目相当新，所以我的路线文件非常简单：

Mrprice::Application.routes.draw do

get "admin/index" => 'admin#index'

 resources :products
 resources :subcategories
 resources :categories

 root to: 'store#index', as: 'root'

end

在我看来：

<%= link_to 'New Subcategory', new_subcategory_path %>

我确定某处有错字，否则解决方案非常简单，但我一生都无法弄清楚。我希望我已经提供了足够的信息，并且这里有人知道问题所在！

编辑：subcategories_controller.rb（相关方法）

def show
@subcategory = Subcategory.find(params[:id])

respond_to do |format|
  format.html # show.html.erb
  format.json { render json: @subcategory }
end
end

def new
@subcategory = Subcategory.new

respond_to do |format|
  format.html # new.html.erb
  format.json { render json: @subcategory }
end
end

  def create
@subcategory = Subcategory.new(params[:subcategory])

respond_to do |format|
  if @subcategory.save
    format.html { redirect_to @subcategory, notice: 'Subcategory was successfully      created.' }
    format.json { render json: @subcategory, status: :created, location: @subcategory }
  else
    format.html { render action: "new" }
    format.json { render json: @subcategory.errors, status: :unprocessable_entity }
  end
end
end

耙路线给出：

     admin_index GET    /admin/index(.:format)            admin#index
    products GET    /products(.:format)               products#index
             POST   /products(.:format)               products#create
 new_product GET    /products/new(.:format)           products#new
edit_product GET    /products/:id/edit(.:format)      products#edit
     product GET    /products/:id(.:format)           products#show
             PUT    /products/:id(.:format)           products#update
             DELETE /products/:id(.:format)           products#destroy
subcategories GET    /subcategories(.:format)          subcategories#index
                 POST   /subcategories(.:format)          subcategories#creat
 new_subcategory GET    /subcategories/new(.:format)      subcategories#new
edit_subcategory GET    /subcategories/:id/edit(.:format) subcategories#edit
     subcategory GET    /subcategories/:id(.:format)      subcategories#show
                 PUT    /subcategories/:id(.:format)      subcategories#updat
                 DELETE /subcategories/:id(.:format)      subcategories#destr
      categories GET    /categories(.:format)             categories#index
                 POST   /categories(.:format)             categories#create
    new_category GET    /categories/new(.:format)         categories#new
   edit_category GET    /categories/:id/edit(.:format)    categories#edit
        category GET    /categories/:id(.:format)         categories#show
                 PUT    /categories/:id(.:format)         categories#update
                 DELETE /categories/:id(.:format)         categories#destroy
            root        /                                 store#index

注意：不确定如何修复格式 - 我已经尝试过代码块

好的，所以我终于想通了！

问题是新子类别表单上的路由错误。我有：

<%= link_to "Subcategories Home", subcategories_index_path %>

我知道这是不正确的，所以我将其更改为：

<%= link_to "Subcategories Home", subcategories_url %>

大多数情况下，我只是用一把细齿梳从外向内完成 Rails Routing，直到我找到了返回子类别#index 的正确方法。
