ActiveRecord::SubclassNotFound after trying to save payment gateway record

[digitalWestie]

I'm using solidus 2.4.2, and after installing gem from latest commit:

gem 'solidus_paypal_braintree', :git => 'https://github.com/solidusio/solidus_paypal_braintree.git', :ref => '898eb2cad5438f1540bf7cb636e90a24038ad4fb'

I ran

g = SolidusPaypalBraintree::Gateway.new(
  name: "Braintree",
  preference_source: "braintree_credentials"
)
g.save

and get:

ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'Solidus::Gateway::BraintreeGateway'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Spree::PaymentMethod.inheritance_column to use another column for that information.

Inspecting the object I see that g.type is "SolidusPaypalBraintree::Gateway" not Solidus::Gateway::BraintreeGateway

Ah, figured it out. Nothing to do with this gem. Before installing this gem I tried out the solidus_braintree gem and then deleted it. What I didn't realise was the payment method record still existed (as it was soft deleted) but the gateway class it was looking for no longer existed.

@digitalWestie how did you solved deleting the gateway class? I'm getting

"ActiveRecord::SubclassNotFound (The single-table inheritance mechanism failed to locate the subclass: 'Solidus::Gateway::BraintreeGateway'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Spree::PaymentMethod.inheritance_column to use another column for that information.)"

Do you have any records in the spree_payment_methods table in your db?

I discovered I had a payment_method record that referred to a class that didn't exist anymore.

@digitalWestie Hi, I found how to fix this issue. Thanks!

> rails console
irb> ActiveRecord::Base.connection.execute("DELETE FROM spree_payment_methods WHERE type='Solidus::Gateway::BraintreeGateway'")
