Oh, I figured this one out. Reason why the else doesn't pop the last

I am finding it difficult to resolve this issue.

Hi all,
In curl (the command line program), I can successfully log a user in
using devise:
def create
respond_to do |format|
format.json {
if user_signed_in?
return render :json = {:success = true, :errors =
[Already logged in.]}
end
thanks for response, the solution I provided also works if you want to
pass params in hash via query string when there isn't a direct
association between multiple models

This was easy resolution:
send_activation_notification(:user_id = @user.id, :account_id =
@account.id)
That will pass the params in query string

It appears that the each iterator does not support passing in two
arguments?
Correct. each means apply this block to each
hey all,
I have this:
scope :path = '/activation', :controller = :activation do
post create = :create
get confirmation = :confirmation, :as = confirmation
get send_activation_notification
= :send_activation_notification, :as = send_activation do
thanks for response, code was an integer, and :code was just a key of
the session hash. But I decided in end to make this database backed.

Hi all,
In Rails console (just doing a general exercise in ruby design
patterns), I create two classes:
ruby-1.9.2-p136 :023 class A
ruby-1.9.2-p136 :024? attr_accessor :name, :balance
ruby-1.9.2-p136 :025? def initialize(name, balance)
ruby-1.9.2-p136 :026? @name = name
ruby-1.9.2-p136
] code if key
So if you see a problem here, maybe I am not understanding.
thanks for response
