Instance Method Details

#respond_to?(name, include_private = false) ⇒ Boolean

This code in this file seems to have a lot of indirection, but the indirection is there to provide extension points for the activerecord-deprecated_finders gem. When we stop supporting activerecord-deprecated_finders (from Rails 5), then we can remove the indirection.

Returns:

  • (Boolean)
