can't write unknown attribute event_id

[jmkoni]

I'm working on upgrading a project to Ruby 3 and am currently running into issues with RailsEventStore. Using the example that is in the docs, here is what happens for me (same thing happens with our own events):

[3] pry> OrderPlaced = Class.new(RailsEventStore::Event)
AccountingHelper::Transaction::OrderPlaced < RubyEventStore::Event
[4] pry> stream_name = "order_1"
[4] pry> stream_name = "order_1"
event =Placed.new(data: { order_id: 1, order_data: "sample", festival_id: "b2d506fd-409d-4ec7-b02f-c6d2295c7edd" })
OrderPlaced.new(data: { order_id: 1, order_data: "sample", festival_id: "b2d506fd-409d-4ec7-b02f-c6d2295c7edd" })
#<OrderPlaced:0x0000000126c67240 @event_id="c8df9997-a7b7-41cc-9f87-d1d83543fd10", @metadata=#<RubyEventStore::Metadata:0x0000000126c66fe8 @h={}>, @data={:order_id=>1, :order_data=>"sample", :festival_id=>"b2d506fd-409d-4ec7-b02f-c6d2295c7edd"}>
[5] pry> event_store.publish(event, stream_name: stream_name)
ActiveModel::MissingAttributeError: can't write unknown attribute `event_id`

I bumped us from rails_event_store 1.3.1 to 2.1.0. Currently running Rails 6.1 and Ruby 3.0.6. I am not sure how to fix this issue.

ActiveModel::MissingAttributeError: can't write unknown attribute event_id

I get this error message when I try to run RES 2.x code on database schema of RES 1.3.x.

There was a pretty big change in the database schema in 2.x series for performance and storage size reasons. In order to fully upgrade from 1.3.x you need to run schema migrations. The migrations were included in 2.0.0 release and removed in further releases. Specifically it was this one:
https://github.com/RailsEventStore/rails_event_store/blob/v2.0.0/rails_event_store_active_record/lib/rails_event_store_active_record/generators/templates/no_global_stream_entries_template.rb

The details and migration steps are described in 2.0.0 release changelog entry:
https://github.com/RailsEventStore/rails_event_store/releases/tag/v2.0.0

I'm working on upgrading a project to Ruby 3

Was there anything in RES 1.3.1 release not working on Ruby 3.0.6?

@pawelpacana Thank you! I'll try running the migrations. Re 1.3.1 & 3.0.6, iir there was another gem that forced me to update, not rails_event_store alone.
