uninitialized constant User::Subscription

[abrambailey]

When trying to subscribe to a plan, I see the following error:

uninitialized constant User::Subscription

Here is the relevant part of my User class:

  has_many :orders, foreign_key: :user_id, class_name: "Spree::Order"
  has_many :subscriptions, foreign_key: :user_id, class_name: "Spree::Subscription"

Same problem.

@abrambailey, @cellis Could you please specify the steps to reproduce this problem.

[cellis]

@abrambailey, @praveendhawan this is probably happening because I'm not using Spree::User but instead using custom authentication, which user_decorator.rb is unable to see, and therefore has_many :subscriptions doesn't get added. I tried adding has_many :subscriptions, class_name: "Spree::Subscriptions" but that doesn't work either.

@cellis Can you try adding has_many :subscriptions, class_name: 'Spree::Subscription' in your user model ?

[cellis]

@priyank-gupta I've already tried that.

[priyank-gupta]

@cellis Yeah, but the code you pasted above has s in Spree::Subscription. Not sure if its a typo you did here or in code.

[cellis]

@priyank-gupta yeah I typed that out manually. I get the same problem.

[cellis]

Alright, I've figured it out, for anyone coming after and seeing this bug:

If you use custom authentication, you'll need to create your own user decorator.

#spree-app/app/models/user_decorator.rb
#note, not using Spree::User
User.class_eval do
  has_many :subscriptions, class_name: "Spree::Subscription", foreign_key: "user_id"

  def find_or_create_stripe_customer(token=nil)
    return api_customer if stripe_customer_id?
    customer = if token
      Stripe::Customer.create(description: email, email: email, card: token)
    else
      Stripe::Customer.create(description: email, email: email)
    end
    update_column(:stripe_customer_id, customer.id)
    customer
  end

  def api_customer
    Stripe::Customer.retrieve(stripe_customer_id)
  end
end

After adding this file, I see

@cellis Thanks!!!.
I think we should use Spree.user_class across this extension to work with custom user models.
@praveendhawan Can you look into this ?
