Rails

Hi all,

Im using mongodb database in my rails 3 app.i tried to implement
facebook and twitter login in my applications but i failed, one warning
will occure.

The warning is, “ActionDispatch::Cookies::CookieOverflow”

Someone explain for this solutions: You need change your session_store
and don’t use the cookie_store. You can use the active_record_store by
example.

I cant understand this solution, How to solve this warning, can anyone
explain…

Some solution for this warning:

1.Hope you’ve set the whole user record in a session,just set like this
session[:current_user]=@my_user.id

  1. http://api.rubyonrails.org/classes/ActionDispatch/…
    The problem is you are probably storing a large amount of data in your
    cookies. possibly your session. So try looking at the data you are
    storing on your sessions. Try to limit the data being passed around from
    your browser to your server.

    Im following this method solve the solution, but i cant get
    solutions for this warning. same warning will occure…

Can anyone explain…

  Thanks and Regards......

That happens when you are trying to store more than 4kb of session data
in a cookie. You should try to limit the amount of data you are storing
in the cookie, and only keep as little information as necessary for the
session.
