如何防止表单在Rails应用程序中过快重新提交？ [英] How do I prevent a form from being resubmitted too quickly in a rails application?

问题描述

我制作了一个简单的Rails应用程序，允许人们对帖子发表评论。如何防止该用户反复提交该表单？在reddit.com上，他们只允许新用户每十分钟发布一次新帖子。我如何使用我的简单博客/评论系统来做到这一点？任何帮助将不胜感激。感谢您阅读我的问题。
编辑：我试图在没有用户模型的情况下完成此操作。

这是我目前的评论控制器：

  class CommentsController< ApplicationController 
＃before_filter：require_user，：only => [：index，：show，：new，：edit] 
 
 before_filter：post_check 
 
 def record_post_time 
 cookies [：last_post_at] = Time.now.to_i 
结束
 
 def last_post_time 
 Time.at（（cookies [：last_post_at] .to_i rescue 0））
结束
 
 MIN_POST_TIME = 2 .minutes 
 
 def post_check 
返回true if（Time.now  -  last_post_time）> MIN_POST_TIME 
 
＃处理错误
＃flash（帖子太多）
结束
 
 def索引
 @message = Message.find （params [：message_id]）
 @comments = @ message.comments 
 end 
 $ b def show 
 @message = Message.find（params [：message_id]） 
 @comment = @ message.comments.find（params [：id]）
 end 
 $ b def new 
 @message = Message.find（params [：message_id ]）
 @comment = @ message.comments.build 
 end 
 $ b def编辑
 @message = Message.find（params [：message_id]）
 @comment = @ message.comments.find（params [：id]）
结束
 $ b def创建
 @message = Message.find（params [：message_id]）
 @comment = @ message.comments.build（params [：comment]）
＃@ comment = Comment.new（params [：comment]）
 if @ comment.save 
 record_post_time＃
 flash [：notice] =已回复\＃{@ message.title} \
 redirect_to（@message）
＃re direct_to post_comment_url（@post，@comment）＃old 
 else 
 render：action => 新
结束
结束
 
 def更新
 @message = Message.find（params [：message_id]）
 @comment = Comment.find （params [：id]）
 if @ comment.update_attributes（params [：comment]）
 record_post_time 
 redirect_to post_comment_url（@message，@comment）
 else 
 render：action => edit
 end 
 end 
 
 def destroy 
 
 end 
 end 
  

解决方案

试试这个：

  class CommentsController< ApplicationController 
 before_filter：post_check 
 def record_post_time 
 cookies [：last_post_at] = Time.now.to_i 
 end 
 def last_post_time 
 Time.at（（cookie [：last_post_at] .to_i rescue 0））
 end 
 MIN_POST_TIME = 2.minutes 
 def post_check 
返回true if（Time.now  -  last_post_time）> MIN_POST_TIME 
 flash [：notice] =太多评论让你成为一只繁忙的猫！ 
 @message = Message.find（params [：message_id]）
 redirect_to（@message）
返回false 
结束
 def创建
 @comment = Comment.new（params [：comment]）
 if @ comment.save 
 record_post_time 
 else 
 end 
 end 
 
 def update 
 @comment = Comment.find（parms [：id]）
 if @ comment.update_attributes（params [：comment]））
 record_post_time 
 else 
 end 
 end 
 end 
  

I have made a simple Rails application that allows people to comment on posts. How do I prevent that user from submitting that form over and over again? On reddit.com they only allow newer users to make new posts every ten minutes. How can I do this with my simple blog/commenting system? Any help would be greatly appreciated. Thanks for reading my question. EDIT: I'm trying to accomplish this without a user model.

Here's my current Comments controller:

class CommentsController < ApplicationController
  # before_filter :require_user, :only => [:index, :show, :new, :edit]

  before_filter :post_check

  def record_post_time
    cookies[:last_post_at] = Time.now.to_i
  end

  def last_post_time
    Time.at((cookies[:last_post_at].to_i rescue 0))       
  end

  MIN_POST_TIME = 2.minutes

  def post_check
    return true if  (Time.now - last_post_time) > MIN_POST_TIME

    # handle error
    # flash("Too many posts")
  end

  def index
    @message = Message.find(params[:message_id])
    @comments = @message.comments
  end

  def show
    @message = Message.find(params[:message_id])
    @comment = @message.comments.find(params[:id])
  end

  def new
    @message = Message.find(params[:message_id])
    @comment = @message.comments.build
  end

  def edit
    @message = Message.find(params[:message_id])
    @comment = @message.comments.find(params[:id])
  end

  def create
    @message = Message.find(params[:message_id])
    @comment = @message.comments.build(params[:comment])
    #@comment = Comment.new(params[:comment])
    if @comment.save
      record_post_time#
      flash[:notice] = "Replied to \"#{@message.title}\""
      redirect_to(@message)
      # redirect_to post_comment_url(@post, @comment) # old
    else
      render :action => "new"
    end
  end

  def update
    @message = Message.find(params[:message_id])
    @comment = Comment.find(params[:id])
    if @comment.update_attributes(params[:comment])
      record_post_time
      redirect_to post_comment_url(@message, @comment)
    else
      render :action => "edit"
    end  
  end

  def destroy

  end
end

解决方案

Try this:

class CommentsController < ApplicationController
before_filter :post_check        
def record_post_time
  cookies[:last_post_at] = Time.now.to_i
end
def last_post_time
  Time.at((cookies[:last_post_at].to_i rescue 0))       
end    
MIN_POST_TIME = 2.minutes    
def post_check
  return true if  (Time.now - last_post_time) > MIN_POST_TIME
  flash[:notice] = "Too many comments makes you a busy cat!"
  @message = Message.find(params[:message_id])
  redirect_to(@message)
  return false
end
def create
  @comment = Comment.new(params[:comment])
  if @comment.save
    record_post_time
  else
  end
end

def update
  @comment = Comment.find(parms[:id])
  if @comment.update_attributes(params[:comment]))
    record_post_time
  else
  end
end    
end
