class Athena::Validator::Constraints::NegativeOrZero
inherits Athena::Validator::Constraints::LessThanOrEqual #

Validates that a value is a negative number, or 0. Use AVD::Constraints::Negative if you don't want to allow 0.


Optional Arguments#


Type: String Default: This value should be negative or zero.

The message that will be shown if the value is not less than or equal to 0.


The following placeholders can be used in this message:

  • {{ value }} - The current (invalid) value.
  • {{ compared_value }} - The expected value.
  • {{ compared_value_type }} - The type of the expected value.

Type: Array(String) | String | Nil Default: nil

The validation groups this constraint belongs to. AVD::Constraint::DEFAULT_GROUP is assumed if nil.


Type: Hash(String, String)? Default: nil

Any arbitrary domain-specific data that should be stored with this constraint. The AVD::Constraint@payload is not used by Athena::Validator, but its processing is completely up to you
