NoMethodError error on enum with `_default` option set #207

Closed clinejj closed 2 years ago

clinejj commented 2 years ago

We have a class with the following definition:

# == Schema Information
#
# Table name: product_filters
#
#  id               :bigint           not null, primary key
#  display_text_key :string
#  filter_type      :integer          default("select_multiple")
#  created_at       :datetime         not null
#  updated_at       :datetime         not null
#
# Indexes
#
#  index_product_filters_on_display_text_key  (display_text_key) UNIQUE
#
class ProductFilter < ApplicationRecord
  enum filter_type: { select_multiple: 0, select_single: 1, range: 2, text: 3 }, _default: :select_multiple
end

when running bin/rails rbs_rails:all --trace we get the following error:

** Invoke rbs_rails:all (first_time)
** Invoke rbs_rails:generate_rbs_for_models (first_time)
** Invoke environment (first_time)

The task completes as expected if the _default option is commented out, like so:

class ProductFilter < ApplicationRecord
  enum filter_type: { select_multiple: 0, select_single: 1, range: 2, text: 3 } #, _default: :select_multiple
end
