default | Validation of variables |
To validate a variable, each time before it is set, define a validation:
validate :some_key do |key, value|
if value.length < 5
raise Capistrano::ValidationError, "Length of #{key} is too short!"
end
end
Multiple validations can be assigned to a single key. Validations will be executed in the order of registration.
