Method Details

[hide private]

convert_value(self, value)

source code

Transform a value to the desired form.

This is the workhorse method that is called by convert to transform passed values. As such, errors are signalled by throwing a meaningful exception. This is one of the obvious and easiest places to customize behaviour by overriding in a subclass.

Parameters:

value - value to be transformed

Returns:

the transformed value

Overrides: basevalidator.BaseValidator.convert_value
