Question

我不确定我做错了什么，但是当我尝试编辑/更新时，当我点击提交按钮时，我一直收到路由错误，说没有路由匹配[PUT]“/ products”。

我的routes.rb：

  devise_for :users

  root :to => 'products#latest'

  resources :products

  match "/popular"             => "products#popular"
  match "products/like/:id"    => "products#like"
  match "products/unlike/:id"  => "products#unlike"
  match "/tags/:tag"           => "products#latest", as: :tag

控制器：

def edit
    @product = Product.find(params[:id])
    p @product.id
end

def update
    @product = Product.find(params[:id])
    if @product.update_attributes(params[:product])
        flash[:notice] = "Product has been updated."
        redirect_to @product
    else
        flash[:alert] = "Product has not been updated."
        render :action => "edit"
    end
end

表单视图：

        <%= form_for @product, :url => products_path, :html => { :multipart => true } do |f| %> 
        Product Name: <%= f.text_field :name %>
        <br>

        Product Link: <%= f.text_field :product_link %>
        <br>

        Blog Link: <%= f.text_field :blog_link, :class => "form-control" %>
        <br>

        Blog Name: <%= f.text_field :blog_name, :class => "form-control" %>
        <br>

        Description: <%= f.text_field :description, :class => "form-control" %>
        <br>

        <%= f.label :tag_list, "Tags (separated by commas)" %><br />
        <%= f.text_field :tag_list %>

         <%= f.file_field :avatar %>
         <br/> 

        <%= f.submit "Save", :class => "btn btn-large btn-success" %>

        <% end %>

Answer 1

尝试将“resources：products”放在devise_for块之外。要显示可用的路由，请键入console：bundle exec rake routes

Answer 2

您将表单提交至/products而非/products/<id>。

将form_for行更改为

<%= form_for @product, :html => { :multipart => true } do |f| %>

和Rails将生成一个包含正确URL的表单。

如果由于某种原因您希望保留:url选项，则可以使用:url => @product或:url => product_path(@product)。
