Validators

This is a reference for all of the base validators included with the library. Any custom validators can be added as required by following the instructions mentioned here.

Validators are used in the Fields for validating the data used in the bots.

RequiredValidator

Validates that the given value isn't Null. Generally used to make sure that the field either has a default set or has a value passed into the step.

MaxLengthValidator

• length - Maximum length allowed for the value

Validates that the given value doesn't exceed the provided length, and that the value HAS a length in the first place.

TypeValidator

• field_type - The type the value must be of

Validates that the given value is an instance of the given field_type.

OptionsValidator

• options - A list of the options that the value must be a part of

Validates that the given value matches one of the options in the options array.

FilePathValidator

Validates that the given value is a path to an existing file on the system.

ResolvedVariableValidator

• required_type - The type the value must be of if it isn't a resolved variable

Validates that the variable is either a correctly formatted resolved variable, or that it matches the given required_type. Note that this doesn't validate if the resolved variable is going to be in the context during the step's execution since the validation is done prior to any execution.
