Question

我有一个用户可以上传图钉的rails应用程序，我想使用[acts_as_commentable_gem][1]允许用户注释图钉，这是我的配置：

应用/模型/ pin.rb

class Pin < ActiveRecord::Base
    acts_as_commentable 
end

应用/ controlers / pins_controller.rb

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

应用/视图/针/ show.html.erb

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

app / models / comment.rb

class Comment < ActiveRecord::Base

  include ActsAsCommentable::Comment

  belongs_to :commentable, :polymorphic => true

  default_scope -> { order('created_at ASC') }

  # NOTE: install the acts_as_votable plugin if you
  # want user to vote on the quality of comments.
  #acts_as_voteable

  # NOTE: Comments belong to a user
  belongs_to :user
end

应用/控制器/ pin_controller.rb

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

终于在我的配置/路线中

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

但是我遇到了路由错误：

未定义的局部变量或方法`acts_as_commentable＆＃39; for PinsController：Class

我真的不确定这个错误来自哪里，有什么想法？

我不太确定，但你的路线不应该像

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

Rails在引脚上评论gem Acts_as_commentable
