I have read that request.session_options[:id] will fetch the session_id, is that the one that is usually stored in session cookie? Please guide me if my way of understanding is wrong.Thanks in advance

推荐答案

在Rails中，调用会话或cookie哈希很简单.

In Rails, it is simple as calling the session or cookies hash.

# Set a simple session cookie
cookies[:user_name] = "david" 
# Read a cookie 
cookies[:user_name]  # => "david"
# Delete a key
cookies.delete :user_name

会话也是如此.因此，您正在寻找的信息可能在这两个信息之一之内.

The same goes for session. So, the information that you are looking for is probably inside one of these two.
