我在订阅模型上设置了Stripe和PayPal。我需要帮助了解如何在订阅和用户模型之间创建关联。

对此的任何帮助将不胜感激。

订阅模式：

    belongs_to :plan
      validates_presence_of :plan_id
      validates_presence_of :email

      attr_accessor :stripe_card_token, :paypal_payment_token

      def save_with_payment
        if valid?
          if paypal_payment_token.present?
            save_with_paypal_payment
          else
            save_with_stripe_payment
          end
        end
      end

      def paypal
        PaypalPayment.new(self)
      end

      def save_with_paypal_payment
        response = paypal.make_recurring
        self.paypal_recurring_profile_token = response.profile_id
        save!
      end

      def save_with_stripe_payment
        customer = Stripe::Customer.create(description: email, plan: plan_id, card: stripe_card_token)
        self.stripe_customer_token = customer.id
        save!
      rescue Stripe::InvalidRequestError => e
        logger.error "Stripe error while creating customer: #{e.message}"
        errors.add :base, "There was a problem with your credit card."
        false
      end

      def payment_provided?
        stripe_card_token.present? || paypal_payment_token.present?
      end

  def cancel_recurring
     response = ppr.cancel_subscription(at_date_end: true)
     self.current_date_end_at = Time.at(response.current_date_end)
     self.plan_id = plan.id
     self.status = "canceled"
     return self.save
   end
    end

我可能有一个has_one - ＆gt;用户和订阅之间的belongs_to。订阅有许多属性可以随着时间的推移而发生很大变化，在设计任何问题时，您应该问的第一个问题是“随着时间的推移会发生什么变化？”

然后，您可以在用户上为语法糖

创建subscribed?方法

class User < ActiveRecord::Base
  has_one :subscription

  def subscribed?
    subscription.present?
  end
end

class Subscription < ActiveRecord::Base
  belongs_to :user
end

您希望在user_id的订阅表中添加一列，以便正确使用该关联。

此外，在迁移中，您可以使用belongs_to添加此列（如果您使用的是较新版本的Rails：

create_table :subscriptions do |t|
  t.belongs_to :user
  t.string :account_id
  t.timestamps
end

如果您已正确设置了所有内容，那么这应该适用于rails console：

User.first.subscription # => Subscription<>
Subscription.first.user # => User <>

将订阅模型与用户模型相关联
