hi!
im implementing a login system for a messageboard. tooked from a book.
pretty simple. everythings works great, but in the example the idea is,
when i want to create a new message, the author name shall be tooked
from the session[:user]
def create
params[:message][:date] = Time.now
params[:message][:author_id] = @session[:user].id #here!!
@message = Message.new(params[:message])
if @message.save
flash[:notice] = ''Message was successfully created.''
redirect_to :action => ''list''
else
render :action => ''new''
end
end
but i recive this error:
"Called id for nil, which would mistakenly be 4 -- if you really wanted
the id of nil, use object_id"
i dont know why, im following the example step by step. what can i do?
ty!!

I''m not sure what example you are referring to, but in your login method you need to add the user to the session. new_user = User.new() ... session[:user] = new_user btw, I think the convention is to use session not @session. The same goes for request, response, flash and some others that escape me right now. good luck, andy -- Andrew Stone -------------- next part -------------- An HTML attachment was scrubbed...

depending what book or tut you followed, session[:user] might be the user id, not the user object. if that doesn''t work, then what andy said... ed On 7/25/06, Andrew Stone <stonelists@gmail.com> wrote:> > but i recive this error: > > "Called id for nil, which would mistakenly be 4 -- if you really wanted > > the id of nil, use object_id" > > > > > This means session[:user] hasn''t been set yet.
