The nova.api.validator Module

validate(args, validator)

Validate values of args against validators in validator.

Parameters:

• args – Dict of values to be validated.
• validator – A dict where the keys map to keys in args and the values are validators. Applies each validator to args[key]

Returns:

True if validation succeeds. Otherwise False.

A validator should be a callable which accepts 1 argument and which returns True if the argument passes validation. False otherwise. A validator should not raise an exception to indicate validity of the argument.

Only validates keys which show up in both args and validator.
