Как отменить подписку на Paypal?

Question

Я наконец понял, как реализовать PayPal Recurring Billing, используя этот учебник. http://railscasts.com/episodes/289-paypal-recurring-billing

Все работает, но как же отменить подписку ....

Ниже всего кода я написал, и я также добавил некоторые комментарии/вопросы

ОШИБКА

app/controllers/subscriptions_controller.rb:27:in `show' 

Couldn't find Subscription with id=cancel_account 

Пожалуйста, помогите новому для рельсов. :)

КОНТРОЛЛЕР

class SubscriptionsController < ApplicationController 

    def new 
    plan = Plan.find(params[:plan_id]) 
    @subscription = plan.subscriptions.build 
    @subscription.user_id = current_user.id 
    if params[:PayerID] 
     @subscription.paypal_customer_token = params[:PayerID] 
     @subscription.paypal_payment_token = params[:token] 
     @subscription.email = @subscription.paypal.checkout_details.email 
    end 
    end 

    def create 
    @subscription = Subscription.new(params[:subscription]) 
    if @subscription.save_with_payment 
     redirect_to @subscription, :notice => "Thank you for subscribing!" 
    else 
     render :new 
    end 
    end 

    def destroy 
    @subscription = current_user.subscription 
    @previous_plan = @subscription.plan 

    if @subscription.cancel_recurring 
     flash[:success] = 'Subscription Canceled.' 
    end 
    redirect_to some_path 
    end 

    def paypal_checkout 
    plan = Plan.find(params[:plan_id])

     return_url: new_subscription_url(:plan_id => plan.id), 
     cancel_url: root_url

МАРШРУТЫ

App::Application.routes.draw do 

    resources :subscriptions do 
    collection do 
     delete :cancel_account 
    end 
    end 

    get 'paypal/checkout', to: 'subscriptions#paypal_checkout' 

end 

Answer 1

Чтобы уничтожить пользователей системы PayPal подписки вы должны создать уничтожить действие в вашей модели подписки.

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 

В модели получить текущего пользователя и отменить подписку. Если пользователь подписывается ежемесячно, но отменяется в течение 2 дней из 30 дней, их подписка на подписку должна быть действительной до периода at_end_date (только хэдз-ап).

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 

По вашему мнению вы бы перебирать планы, как так

<% @plans.each do |plan| %> 
    <%= link_to "Cancel Account", cancel_account_subscriptions_path(@subscription, plan_id: plan.id), method: :delete %> 
<% end %>
