Hi i’m trying to get the paypal library working in my rails app. I know  
this is the ruby forum but i think this might be half a ruby question. I  
installed the paypal gem.

$ gem list

\*\*\* LOCAL GEMS \*\*\*

##rails ones + others##

money (1.7.1)  
Class aiding in the handling of Money.

paypal (2.0.0)  
Paypal IPN integration library for rails and other web applications  
#############

irb(main):001:0\> require ‘rubygems’  
=\> true  
irb(main):002:0\> require ‘paypal’  
=\> false  
irb(main):003:0\> include Paypal  
NameError: uninitialized constant Paypal  
from (irb):3  
irb(main):004:0\> include paypal  
NameError: undefined local variable or method `paypal’ for  
#Object:0xb7cdd970  
from (irb):4

when i try and use the form helpers in rails  
specifically the code below taken from the RDoc:

\<%= paypal\_form\_tag %\>  
25: \<%= paypal\_setup “Item 500”, Money.us\_dollar(50000),  
“removed\_email\_address@domain.invalid”, :notify\_url =\> url\_for(:only\_path =\> false,  
:action =\> ‘paypal\_ipn’) %\>

if get this error:  
undefined local variable or method `paypal\_form\_tag’ for  
#\<#Class:0xb7692568:0xb7692540\>

Extracted source (around line #24):

21:   
22:   
23:  
24: \<%= paypal\_form\_tag %\>

I have added require ‘paypal’ to the end of my enviroment.rb .  
I have this as my application\_helper.rb

require ‘paypal’  
module ApplicationHelper  
include Paypal::Helpers  
end

I also now get this in my log

ApplicationController: missing default helper path application\_helper

Please give me something else to try.  
I am stumped!  
regards  
c

require ‘net/https’

Rails 1.1.6

?
