Question

您好我正在开发一个演示电子商务应用，我在其中创建了产品，用户和评论。每个产品页面都应显示特定产品的注释。我可以评论产品A，然后我可以看到产品A的所有评论，但是，如果我查看产品B的页面，我也会看到产品A的评论。所以基本上，所有评论都混淆了一长串而不是为产品排序...... 这是我的github：https://github.com/Adsidera/FreshObst 以下是评论的部分产品/ _comment.html.erb

<div class="product-reviews">

<% @comments.each do |comment| %>

    <div class="row" style="padding-left:4%;">
        <HR>
            <p><small><%= comment.user.first_name %><em><%= " #{time_ago_in_words(comment.created_at)} ago" %></em></small></p>
            <div class="rated" data-score="<%= comment.rating %>"></div>

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

            <% if signed_in? && current_user.admin? %> 
            <p><%= link_to  product_comment_path( @product, comment), method: :delete, data: { confirm: 'Are you sure?'} do %>
                <i class="fa fa-trash-o fa-fw"></i>
                <% end %>
            </p>
            <% end %>

    </div>
<% end %>

这是评论控制器

    class CommentsController < ApplicationController

# So admin abilities are applied to only these.  
# So public can view product without signing in.
load_and_authorize_resource :only => [:destroy]

def index

end

def create
    @product = Product.find(params[:product_id])
    @comment = @product.comments.new(comment_params)
    @comment.user = current_user

    respond_to do |format|
        if @comment.save
            format.html { redirect_to @product, alert: 'Review was created successfully'}
            format.json {render :show, status: :created, location: @product}
        else
            format.html { redirect_to @product, alert: 'Review could not be saved'}
            format.json { render json: @comment.errors, status: :unprocessable_entity }
        end
    end

end

def destroy
    @product = Product.find(params[:product_id])
    @comment = Comment.find(params[:id])
    product  = @comment.product
    @comment.destroy
        respond_to do |format|
            format.html {redirect_to @product, alert: 'Comment deleted successfully'}
            format.json {render :show, location: @product}
        end 
end

def show
end

private

def comment_params
    params.require(:comment).permit(:user_id, :body, :rating)
end
end

这是我的产品控制器https://github.com/Adsidera/FreshObst/blob/master/app/controllers/products_controller.rb

问题在于产品控制器的show方法，就像这样：

  def show
      @product = Product.find(params[:id])
      # @comment = current_user.comment.build(comment_params)
      @comments = @product.comments.order("created_at DESC")
      @comments = Comment.paginate(:page => params[:page], :per_page => 3).order("created_at DESC")
  end

应该是这样的：

  def show
      @product = Product.find(params[:id])
      @comments = @product.comments.paginate(:page => params[:page], :per_page => 3).order("created_at DESC")
  end

针对特定产品的评论显示所有产品
