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

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.
