Why does this hash syntax not work in Rails?

Question

session[:user => user, :user_id => [user.id, user.salt]]

For some reason, that never worked for me.

Thoughts on how I can achieve the following code in one line:

session[:user] = user
session[:user_id] = [user.id, user.salt]

Answer 1

Try

 session.merge({:user => user, :user_id => [user.id, user.salt]})
