def checkout
recipients = [recipientarray]
response = gateway.setup_purchase(
:return_url => url_for(:action => 'action', :only_path => false),
:cancel_url => url_for(:action => 'action', :only_path => false),
:ipn_notification_url => url_for(:action => 'notify_action', :only_path => false),
:receiver_list => recipients
)
# For redirecting the customer to the actual paypal site to finish the payment.
redirect_to (gateway.redirect_url_for(response["payKey"]))
end
It is redirecting to the paypal payment page..
This is the page
In payment summary it does not displaying any item name , price, etc..
can any one suggest how to configure it . Please help

You may want to try using the "ActiveMerchant" gem instead - it's updated by Shofify and we've got it to do exactly what you're looking for.
Problem
The way to get PayPal to list the items is to use the ExpressCheckout version (I think you're just setting up a peer-to-peer payment), and then pass the items in a hash array. We use a cart, but you may have something else.
The trick with paypal epxress is that you have to get all the totals to add up properly. As you will see in the code I post, we are just using a static shipping value for now (we're still developing this current project), but you can omit shipping if you don't need it.
Solution
I can only vouch for ActiveMerchant, because that's the only code I've got, but here is what we do:
Routes
#config/routes.rb
get 'checkout/paypal' => 'orders#paypal_express', :as => 'checkout'
get 'checkout/paypal/go' => 'orders#create_payment', :as => 'go_paypal'
Orders Controller
#controllers/orders_controller.rb
class OrdersController < ApplicationController
#Paypal Express
def paypal_express
response = EXPRESS_GATEWAY.setup_purchase(total,
:items => cart_session.build_order, #this is where you create the hash of items
:subtotal => subtotal,
:shipping => 50,
:handling => 0,
:tax => 0,
:return_url => url_for(:action => 'create_payment'),
:cancel_return_url => url_for(:controller => 'cart', :action => 'index')
)
redirect_to EXPRESS_GATEWAY.redirect_url_for(response.token)
end
#some other stuff is here....
end
Build Items
#models/cart_session.rb (we use this with a cart)
#Build Hash For ActiveMerchant
def build_order
#Take cart objects & add them to items hash
products = cart_contents
#order = []
products.each do |product|
#order << {name: product[0].name, quantity: product[1]["qty"], amount: (product[0].price * 100).to_i }
end
return #order
end
end
