Vex Extra Validators

Note: If you are using the Number and/or the UUID validators, we suggest to use instead the ones from the Vex package as we made a PR and it was accepted!

Vex is an extensible data validation library for Elixir.

This library provides new validator modules that can be used as sources in Vex.

Installation

Add vex_validators to your list of dependencies in mix.exs:

def deps do
  [
    {:vex_validators, github: "StoiximanServices/vex_validators"}
  ]
end

Then add in your config.exs the following configuration to add as an additional source for Vex:

config :vex,
  sources: [VexValidators, Vex.Validators]

The extra validators

Additionally to the built-in Vex validators, vex_validators also provides the following validators.

For more information on how to use the validators, please see the Vex documentation.

Number

Ensure a value is a number equal to another:

Vex.valid? post, [number: [==: 1]]

Ensure a value is a number greater than another:

Vex.valid? post, [number: [<: 1]]

Ensure a value is a number less than another:

Vex.valid? post, [number: [<: 1]]

This validation can be skipped for nil or blank values by including allow_nil: true and/or allow_blank: true.

See the documentation on VexValidators.Number for details on available options.

Type

Ensure a value is of a specific Elixir type:

Vex.valid? post, [type: :string]

This validation can be skipped for nil or blank values by including allow_nil: true and/or allow_blank: true.

See the documentation on VexValidators.Type for details on available options.

UUID

Ensure a value is a valid UUID string:

Vex.valid? post, [id: [uuid: true]]

To check if the value is a valid UUID of a specific format:

Vex.valid? post, [id: [uuid: :hex]]

See documentation on VexValidators.Uuid for details on available options.
