ruby-on-rails - Rails 4, raw query using ActiveRecord

Question

Is there currently a way to do a raw SQL select query using ActiveRecord in Rails 4.0.0.beta1? I see ActiveRecord::Base.execute no longer exists. What's the correct way of going about this?

Answer 1

10 ペンスを追加するだけで、Model.connection.execute を使用した生のクエリは ActiveRecord モデルを返さず、生のデータ セットを返します。

以下は ActiveRecord モデルを返します。

MyModel.find_by_sql(query)

編集：もちろん、選択を実行していると仮定します。

Answer 2

In Rails 4 (perhaps previous versions as well), if you're going with a custom query for speed, you can add a :skip_logging argument to avoid writing to the log:

query = "SELECT ..."
results = MyModel.connection.execute(query, :skip_logging)

(Note: If I'm reading the sources correctly, this might not hold true in PostgreSQL.)
