当我用refractor实现ruby on rails时出错

Question

我正在尝试用refraction实现入门ruby on rails的博客，当我想写一条评论时，它会说：

NoMethodError in CommentsController#create
undefined method `permit' for {"commenter"=>"lkjlkm", "body"=>",knm,m"}:ActiveSupport::HashWithIndifferentAccess
Rails.root: C:/Sites/blog2
Application Trace | Framework Trace | Full Trace
app/controllers/comments_controller.rb:8:in `create'

{"utf8"=>"✓",
 "authenticity_token"=>"rh9Kq6QxfXuZxlM9nFvsAjxiA5UnueEFKJ3ypcKy3xQ=",
 "comment"=>{"commenter"=>"lkjlkm",
 "body"=>",
knm,
m"},
 "commit"=>"Create Comment",
 "post_id"=>"5"}
Show session dump
Show env dump
Response

None

我的comments_controller代码是：

 class CommentsController < ApplicationController
http_basic_authenticate_with name: "antonio", password: "opening", only: :destroy
def create
@post = Post.find(params[:post_id])
@comment = @post.comments.create(params[:comment].permit(:commenter, :body))
redirect_to post_path(@post)
end
def destroy
@post = Post.find(params[:post_id])
@comment = @post.comments.find(params[:id])
@comment.destroy
redirect_to post_path(@post)
end
end

我希望你尽快回答感谢所有

最好的方法是将其定义为类似的私有方法

@comment = @post.comments.create(comment_params)
private
def comment_params
   params.require(:comment).permit(:commenter, :body)
end
