class method
self.delete
Ruby on Rails 2.2.3
Since v2.2.3 Last seen in v2.3.18Available in: v2.2.3 v2.3.18
Signature
self.delete(id)Delete an object (or multiple objects) where the id given matches the primary_key. A SQL DELETE command is executed on the database which means that no callbacks are fired off running this. This is an efficient method of deleting records that don’t need cleaning up after or other actions to be taken.
Objects are not instantiated with this method, and so :dependent rules defined on associations are not honered.
Parameters
-
id- Can be either an Integer or an Array of Integers.
Examples
# Delete a single object Todo.delete(1) # Delete multiple objects todos = [1,2,3] Todo.delete(todos)
Parameters
-
idreq
