Deleting a record from database

In Ruby on Rai开发者_如何学运维ls, is it @variable.delete or @variable.destroy

@variable.destroy will call all callbacks (before_destroy etc.) as well as ensure associations are respected. @variable.delete just calls the raw database query to delete the object. You're generally much safer off using destroy even if it's more expensive.

Assuming that you're using ActiveRecord, and that @variable is an instance of an ActiveRecord::Base subclass, you call @variable.destroy.
