Ruby on rails 4 Rails注释gem在pin上充当可注释的角色

我有一个rails应用程序，用户可以在其中上载PIN，我想使用

[acts\u as\u commentable\u gem][1]

允许用户对PIN进行注释，以下是我的配置：

app/models/pin.rb

class Pin < ActiveRecord::Base
    acts_as_commentable 
end

def show
   @pin.find params[:id]
   @comment = @pin.comments.new
end

<%= form_tag "/pins/add_new_comment" do %>
    <%= hidden_field_tag "id", post.id %>
    <%= text_area_tag "comment[comment]" %>
    <%= submit_tag "Pin Comment" %>
    <% end %>

def add_new_comment
    pin = Pin.find(params[:id])
    pin.comments << Pin.new(params[:comment])
    redirect_to :action => :show, :id => pin
end

app/views/pins/show.html.erb

class Pin < ActiveRecord::Base
    acts_as_commentable 
end

def show
   @pin.find params[:id]
   @comment = @pin.comments.new
end

<%= form_tag "/pins/add_new_comment" do %>
    <%= hidden_field_tag "id", post.id %>
    <%= text_area_tag "comment[comment]" %>
    <%= submit_tag "Pin Comment" %>
    <% end %>

def add_new_comment
    pin = Pin.find(params[:id])
    pin.comments << Pin.new(params[:comment])
    redirect_to :action => :show, :id => pin
end

但我遇到了一个路由错误：

PinsController:Class的未定义局部变量或方法“作为可注释的”

get "/pins/add_new_comment" => "pins#add_new_comment", :as => "add_new_comment_to_pins", :via => [:pin]

---

我真的不确定这个错误是从哪里来的，有什么想法吗？

我真的不确定，但您的路线不应该是这样的

get "/pins/:id/add_new_comment" => "pins#add_new_comment", :as => "add_new_comment_to_pins"
