How to Cancel Paypal Subscription? - ruby-on-rails

Question

I finally figured out how to implement PayPal Recurring Billing using this tutorial. http://railscasts.com/episodes/289-paypal-recurring-billing
Everything works, But how does one cancel the subscription....
Below is all of the code I've written, and I've also added some comments/questions
ERROR
app/controllers/subscriptions_controller.rb:27:in `show'
Couldn't find Subscription with id=cancel_account
Please help new to rails. :)

#subscription.paypal_payment_token = params[:token]
#subscription.email = #subscription.paypal.checkout_details.email

Answer 1

To destroy a users paypal subscription you should create a destroy action in your subscription model.
Subscription_controller.rb
def destroy
#subscription = current_user.subscription
#previous_plan = #subscription.plan
if #subscription.cancel_recurring
flash[:success] = 'Subscription Canceled.'
end
redirect_to some_path
end
In your model get the current user and cancel their subscription. If the user is subscribed monthly but canceled within 2days out of the 30 days, their account subscription should be valid until the at_end_date period(just a heads up).
def cancel_recurring
response = ppr.cancel_subscription(at_date_end: true) #Needs a end period field in
self.current_date_end_at = Time.at(response.current_date_end)
self.plan_id = plan.id
self.status = "canceled"
return self.save
end
Routes.rb
resources :subscriptions do
collection do
delete :cancel_account
end
end
In your view you would iterate through the plans like so
<% #plans.each do |plan| %>
<%= link_to "Cancel Account", cancel_account_subscriptions_path(#subscription, plan_id: plan.id), method: :delete %>
<% end %>
