Basic Usage
The Json constraint can be applied to a property or a “getter” method:
Options
message
type: string default: This value should be valid JSON.
This message is shown if the underlying data is not a valid JSON value.
payload
type: mixed default: null
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.
For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
