::加载ActiveModel ForbiddenAttributesError [英] ActiveModel::ForbiddenAttributesError

问题描述

我一直在关注如何在这里创建和安装引擎。创建的博客文章当我试图评论时，它返回Brough :: CommentsController＃create中的ActiveModel :: ForbiddenAttributesError错误。
评论控制器

i've been following rails guide on creating and mounting an engine here.Created blog post and when i tried to comment ,it returned "ActiveModel::ForbiddenAttributesError in Blorgh::CommentsController#create " error. Comment controller

    require_dependency "blorgh/application_controller"

module Blorgh
  class CommentsController < ApplicationController
    def create
      @post = Post.find(params[:post_id])
      @comment = @post.comments.create(params[:comment])
      flash[:notice] = "Comment has been created!"
      redirect_to posts_path
    end
  end
end

这里是评论模型

and here is comment model

 module Blorgh
  class Comment < ActiveRecord::Base

  end
end

如何解决问题是什么？

推荐答案

我猜你正在使用rails 4.你需要在这里标记所有必需的参数
去：：

I guess you are using rails 4. You need to mark all the required parameters here it goes :

   def create
      @post = Post.find(params[:post_id])
      @comment = @post.comments.create(post_params)
      flash[:notice] = "Comment has been created!"
      redirect_to posts_path
    end

    def post_params
      params.require(:blorgh).permit(:comment)
    end
