Validation

Extended validation for validator in Go.

Usage

You can use this as a replacement for validator:

type User struct {
    Name    string   `validate:"required,min=5"`
    Email   string   `validate:"required,email"`
    Address Address  `validate:"required,nested"`
}

func (u User) Validate() error {
    return validation.Validate(u)
}

type Address struct {
    City string `validate:"required,min=5"
}

func (a Address) Validate() error {
    return validation.Validate(a)
}

or just for adding some "missing" constraints:

func init() {
    // Validates a value or its length when non-zero.
    validator.SetValidationFunc("min", validation.Minimum)
    // Validates a string to be an email address.
    validator.SetValidationFunc("email", validation.Email)
    // Validates a value to be not nil, not zero-value, not empty.
    validator.SetValidationFunc("required", validation.Required)
    // Find more validation funcs in the source code...
}
