Sessions

Rails

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?

This means session[:user] hasn’t been set yet. 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,

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…
