ruby-on-rails - find_or_initialize_by方法的Rails弃用警告

Question

我正在从3.2升级到Rails4。我有以下查询:

progress = Progress.find_or_initialize_by_chore_id_and_period_and_account_id(chore.id, period[chore.frequency], chore.account_id)

运行测试时，我收到了弃用警告

DEPRECATION WARNING: This dynamic method is deprecated. Please use e.g. Post.find_or_initialize_by(name: 'foo') instead. (called from bump_progress at /Users/newimac/RailsApp/bank/app/models/child.rb:200)

因此，我将查询更新如下:

progress = Progress.where('chore.id' => 'chore_id', 'period[chore.frequency]' => 'period', 'chore.account_id' => 'account_id').first_or_initialize

但是它不起作用。我的查询正确吗？

Answer 1

您可以使用以下内容:

Progress.find_or_initialize_by(chore_id: chore.id, period: period[chore.frequency], account_id: chore.account_id)
