Updating column from being NULL after action is called - ruby-on-rails

Question

Stripe is setup on my app and users can cancel or upgrade their subscription. It communicates perfectly to Stripe. I need help figuring out how I can make the changes communicate with my database.
If a user cancels their subscription it should be marked in the Subscriptions table under a cancelled column. With this in place the user will be restricted access to website if it shows in the database that their subscription was cancelled.
I am not sure how to add this to the cancel subscription action I have setup.
Help with this would be greatly appreciated!
Subscriptions controller:
def new
plan = Plan.find(params[:plan_id])
#subscription = plan.subscriptions.build
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 show
#subscription = Subscription.find(params[:id])
end
def updatesubscription
#user = current_user
#customer = Stripe::Customer.retrieve(#user.subscription.stripe_customer_token)
#customer.update_subscription(:plan => "1", :prorate => true)
current_user.save!
flash.alert = 'Your subscription has been updated!'
redirect_to root_url
end
def cancelsubscription
#user = current_user
#customer = Stripe::Customer.retrieve(#user.subscription.stripe_customer_token)
#customer.cancel_subscription()
current_user.save!
flash.alert = 'Your subscription has been cancelled successfully!'
redirect_to root_url
end
def showcard
#user = current_user
Stripe::Customer.retrieve(#user.subscription.stripe_customer_token).cards.all()
end
def changecard
#user = current_user
#customer = Stripe::Customer.retrieve(#user.subscription.stripe_customer_token)
card = #customer.cards.create({
:card => #user.subscription.stripe_customer_token
})
#customer.default_card = card
#customer.save
end
end
Subscription model:
belongs_to :plan
belongs_to :subscription
belongs_to :user
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 suspend_paypal
paypal.suspend
save
end
def reactivate_paypal
paypal.reactivate
save
end
end

Answer 1

The simplest way to do it would be to add extra lines to update the required column.
def cancelsubscription
#user = current_user
#customer = Stripe::Customer.retrieve(#user.subscription.stripe_customer_token)
#customer.cancel_subscription()
current_user.subscription.update_attributes(:cancelled => 1)
current_user.save!
flash.alert = 'Your subscription has been cancelled successfully!'
redirect_to root_url
end
However, ideally all this should happen within a model. From the controller you should just be telling the model to cancel the subscription.
So, this method could become something like:
#subscriptions_controller.rb
def cancelsubscription
current_user.subscription.cancel_stripe_subscription
flash.alert = 'Your subscription has been cancelled successfully!'
redirect_to root_url
end
#subscription.rb model
def cancel_stripe_subscription
customer = Stripe::Customer.retrieve(self.stripe_customer_token)
customer.cancel_subscription()
self.cancelled = 1
self.save!
end

Cant you update the Subscription table via an active_record query? Like this:
updateQuery = ActiveRecord::Base.connection.execute("UPDATE Subscription SET cancelled = 'Cancelled' WHERE user_id = #{#user.id}")
That'd update your subscription table and change the targetted field value to "Cancelled". Its not clear if this is a boolean or not. If it is, then the value should be "TRUE" instead of the "Cancelled" string i put in there.
If subscription succesfully saves, then you execute the query. But you'd have to make sure you put the query between a condition so that it only executes it when the user has cancelled the subscription, not every time its updated.
respond_to do |format|
if #subscription.save
if (something to tell the controller you are cancelling the subscription)
EXECUTE QUERY HERE
end
end
end
