rails update without callback
class User < ApplicationRecord
def update_without_callback(attribute, value)
update_columns(attribute => value)
end
end
Explanation:
- update_without_callback
is a custom method defined within the User
model.
- This method uses update_columns
to update specific attributes of the user directly in the database without triggering any ActiveRecord callbacks or validations.
- It takes two arguments: attribute
(the name of the attribute to be updated) and value
(the new value for that attribute).
- By using update_columns
, the update operation bypasses callbacks like before_save
, before_update
, etc., and directly updates the database columns with the given values.
- Be cautious when using update_columns
as it skips validations and callbacks, potentially leading to inconsistent data if not used carefully.
