无法使用 frindly_id 通过 slug 找到对象 找不到没有 ID 的文章

Question

我就像你看到的那样，我只是想在每篇文章显示页面上发表评论，我也在使用 Friendly_id。问题是我无法使用评论控制器中的 slug 找到这篇文章，我不确定问题出在哪里。

评论控制器

 class CommentsController < ApplicationController

  def create
    @article = Article.friendly.find(params[:slug])
    @comment = @article.comments.create(comments_params)
    redirect_to @article_path(@article)
  end

private

  def comments_params
    params.require(:comment).permit(:name, :body)
  end
end

文章控制器

class ArticlesController < ApplicationController
before_filter :authenticate_user!, except: [:index, :show]



def index
    @Articles = Article.all
  end

  def new
    @article = Article.new
  end

  def create
    @article = Article.new(article_params)
      if @article.save
        redirect_to @article
      else
        render 'new'
      end
    end

    def show
      find_article
    end

    def edit
      find_article
    end

    def update
      @article = Article.find_by_slug(params[:id])
      if @article.update(article_params)
        redirect_to @article
      else
        render 'edit'
      end
    end

    def destroy
      @article = Article.find(params[:id])
      @article.destroy
      redirect_to root_path
    end

    private

    def find_article
      @article = Article.friendly.find(params[:id])
    end

    def article_params
      params.require(:article).permit(:title, :content, :slug)
    end
  end


comment form

<%= form_for ([@article, @article.comments.build]) do |f| %>
  <%= f.label :Name %>
  <%= f.text_field :Name %>
<br>
  <%= f.label :Body %>
  <%= f.text_area :Body %>
<br>
  <%= f.submit %>
<% end %>


comment

<p><%= comment.content %><p/>


Article Model

class Article < ActiveRecord::Base
  has_many :comments
  extend FriendlyId
  friendly_id :title, use: [:slugged, :finders]
end


Comment Model

class Comment < ActiveRecord::Base
  belongs_to :article
end


Routes

Rails.application.routes.draw do

  devise_for :users
  root 'articles#index'

  resources :articles do
    resources :comments
  end
end

我猜应该是这样的：

class CommentsController < ApplicationController

  def create
    @article = Article.friendly.find(params[:article_id])
    @comment = @article.comments.create(comments_params)
    redirect_to article_path(@article)
  end

private

  def comments_params
    params.require(:comment).permit(:name, :body)
  end
end
