limit times of updating status

Guys - newbie here with big question - at least for me is big :slight_smile:
(pardon if i dont refer to things with the proper terms)

I have a controller here that lets a user update their status
infinitively but what I want to do is
limit them to say only update their status 5 times a day... meaning
every 24 hours, so if they update their status 5 times
they are blocked from doing so but then after 24 hours have past, they
are again allowed to post for 5 times again...
if anyone can help get me on the right track, that will be great.
thanks
se√Īor.

class PostsController < ApplicationController
  def index
    @posts = Post.all(:order => "created_at DESC")
    respond_to do |format|
      format.html
    end
  end

  def create
    @post = Post.create(:message => params[:message])
    respond_to do |format|
      if @post.save
        format.html { redirect_to posts_path }
        format.js
      else
        flash[:notice] = "Message failed to save."
        format.html { redirect_to posts_path }
      end
    end
  end
end

So if I update my status on Monday at 00:05, 06:00, 12:00, 18:00, 23:59

Can I update my status Tuesday at 00:01? I think that your answer should be "no, because you have 5 updates within 24 hours."

However, if I try to update Tuesday at 00:10, I think that it should be OK because only the updates from Monday at 6:00, 12:00, 18:00, and 23:59 have occurred within 24 hours.

So let me rephrase your restriction (as I understand it):

     An update is only allowed if there are fewer
     than 5 updates in the past 24 hours.

Now, given your code in PostsController, I'm assuming that you can't really update a status, but instead you create a post. (Presumably the post indicates one's status, right?)

So that sounds like:

class Post < ActiveRecord::Base
   belongs_to :user
   validates_presence_of :user_id
   before_create :not_too_frequently

   protected
   def not_too_frequently
     recent = self.class.count(:conditions => ['user_id = ? AND created_at > ?',
                                               self.user_id, 24.hours.ago])
     recent < 5
   end
end

You'll notice that I'm also assuming that there is a user_id column since you said "lets a user update their status" and somewhere that means:
class User
   has_many :posts
end

if anyone can help get me on the right track, that will be great.

     format.html
   end
end

def create
   @post = Post.create(:message => params[:message])
   respond_to do |format|
     if @post.save
       format.html { redirect_to posts_path }
       format.js
     else
       flash[:notice] = "Message failed to save."
       format.html { redirect_to posts_path }
     end
   end
end
end

You might also want to do something like:
   self.errors.add_to_base("Only 5 status posting per 24 hours")
and then in the controller:
   flash[:notice] = "Message failed to save: #{@post.errors.on[:base]}"

You could even get really fancy and tell the user how long until a new post would be accepted.
