Steps to reproduce
Let's say we have 2 models:
class Author < ApplicationRecord
has_many :books
end
class Book < ApplicationRecord
belongs_to :author, counter_cache: true
accepts_nested_attributes_for :author
end
Then:
Book.create(title: 'book 1', author_attributes: { name: 'author 1' })
Book.last.update(author_attributes: { name: 'author 2' })
Author.last.books_countExpected behavior
Author.last.books_count should be equal to 1.
This is how it works when you update book author using this way:
Book.last.update(author: Author.create(name: 'author 3'))
Actual behavior
Author.last.books_count equal to 0.
