Hey y'all! Getting this on Rails 7.1.0-alpha:

/home/myuser/.bundle/ruby/3.1/bundler/gems/rails-5cbf61502c69/activerecord/lib/active_record/attribute_methods/serialization.rb:207:in 'serialize': missing keyword: :coder If no default coder is configured, a coder must be provided to serialize. (ArgumentError)

`from /home/myuser/myapp/vendor/solidus/core/lib/spree/preferences/persistable.rb10in

block in <module:Persistable>'

persistable.rb

looks like this:

module Spree
  module Preferences
    module Persistable
      extend ActiveSupport::Concern

      included do
        include Spree::Preferences::Preferable
        serialize :preferences, Hash
        after_initialize :initialize_preference_defaults
      end

      private

      def initialize_preference_defaults
        if has_attribute?(:preferences)
          self.preferences = default_preferences.merge(preferences)
        end
      end
    end
  end
end

Any idea what to do?

We don't have Rails 7.1 support yet, so I'd recommend you downgrade to Rails 7.0.

Sorry boss, I'm afraid I need 7.1 due to Falcon 😞 I'm cool with being the test rabbit! Probably not the right way, but this seems to have taken care of the problem for now:

core/app/models/spree/preference.rb
-  serialize :value
+  serialize :value, YAML

core/app/models/spree/return_item.rb
-    serialize :acceptance_status_errors
+    serialize :acceptance_status_errors, YAML

Now that I got Falcon booting, next up on the menu is a StimulusReflex shopping cart 🙏

I can’t find any

7.1.0-alpha

released yet. Are you working with the rails main branch from GitHub?
