[k-tsuchiya-jp]

Issue Summary:

Using the import! method to update existing data now triggers a duplicate check error.

Environment:

activerecord-import: 1.7.0
rails: 7.2.0.beta2
ruby: 3.1.6

Details:

• import! method is equipped with the on_duplicate_key_update option.
• The target Model for update includes a uniqueness validation.

class Book < ApplicationRecord
  validates :isbn_13, uniqueness: true
end

upsert_attributes = params.map | param | { Book.new(isbn_13: param.isbn_13, title: param.title) }
Book.import! upsert_attributes, on_duplicate_key_update: [:title]

It seems that @compiled is now included in the return value of klass._validate_callbacks.
https://github.com/zdennis/activerecord-import/blob/v1.7.0/lib/activerecord-import/import.rb#L36

      @compiled=
       #<ActiveSupport::Callbacks::Filters::Before:0x00007fb51ac6b980
        @filter=
         #<ActiveRecord::Validations::UniquenessValidator:0x00007fb51ac646f8
          @attributes=[:isbn_13],
          @klass=
           Book(id: integer, isbn_13: string, title: string, created_at: datetime, updated_at: datetime),
          @options={}>,
        @halted_lambda=
         #<Proc:0x00007fb5255f75a8 /usr/local/bundle/gems/activesupport-7.2.0.beta2/lib/active_support/callbacks.rb:665>,

        @user_conditions=[]>,

It appears that @compiled has been added to the return value starting from the following commit:
