I''m new to rails and have a question that seems simple but that I cannot resolve. Is there a way to find the id of the currently logged in user? Thanks, JP -- Posted via http://www.ruby-forum.com/.
JP, It depends on what authorization mechanism you are using, but if the complete user info is stored in the session it would be something like... session[:user].id or, if you are just storing the id in the session and doing a lookup for each access to user data... session[:user] substitute your session variable for the "user" entry. Hope that helps.

If you mean the OS User-Id, there isn''t one. You could use cookies and sessions and assign an id. Or do you mean a database id unique key?

This works for me: @session[''user''].id Out of curiosity I looked at the complete ''user'' hash: @session[''user''] And it returned the groups that the user is a member of. And I cannot find where this information is placed in the session. Is it normal for the user to include the group members from a many-to-many relation (ie. users <-- groups_users --> groups)?

You should be careful about storing the user object in the session.
It''s associations will be cached from the first time they are
accessed. Either just store the id and query the user each request, or
be very sure to reload the stored object and associations when
necessary.
I prefer the approach of storing the user id in the session and
querying it each request.
class User < ActiveRecord::Base
cattr_accessor :current
end
Then populate User.current with each request:
class ApplicationController < ActionController::Base
before_filter do
User.current = User.find(session[:user_id])
end
end
Then you can use User.current anywhere to get the currently logged in user.

Then it''s there and you can just pull it out whenever you need it. I''m new too. sean -- Posted via http://www.ruby-forum.com/.
