Current period end value saving as 0 instead of actual value - ruby-on-rails

Question

I am trying to save the Stripe's user current_period_end to the database. When I create a new subscription the value saves as 0 instead of the actual date their subscription ends.
Is there something I'm missing?
It should be saving as:
"current_period_end": 1441292360
Subscription.rb:
def save_with_stripe_payment
customer = Stripe::Customer.create(description: email, plan: plan_id, card: stripe_card_token)
self.stripe_customer_token = customer.id
self.cancellation_date = customer.subscriptions.first.current_period_end
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

Answer 1

It's possible that this could be an issue with the type of data you're receiving and how you're storing it in your database. Based on the information you have given I would expect you have the wrong field type.
Your code is correct so I would double check to see if your field is a integer.

When Strip creates a new customer it returns the object posted at the bottom of this question.
To access the current_period_end you would need to do customer.subscriptions.data.first["current_period_end"]

Answer 3

This is just a shot in the dark (because I don't know the format of your cancellation_date field or the database you are using), but are you sure you are handling the returned timestamp correctly?
If cancellation_date is a DateTime field, I believe you have to do something like:
cpe = customer.subscriptions.first.current_period_end
self.cancellation_date = Time.at(cpe).to_datetime
If that isn't the problem then I'd use the console and/or the server output to make sure current_period_end is returning what you expect it to when you call Stripe::Customer.create (like others have suggested). You really need to determine when the "switch to 0" is happening, so I'd check (in this order):
The response from Stripe when you create the customer
The value of customer.subscriptions.first.current_period_end
The value of self.cancellation_date after assignment but before saving
There may also be validations or before_save filters that are messing with this field before hitting the database.
That's all my ideas for now :)
Hope this helps!
