ozzo validation in rules returns error for equal values

Question content

I have a simple code that uses echo as the engine and ozzo-validation Act as a request validator.

func (a MyRequest) Validate() error {
    return validation.ValidateStruct(
        &a,
        validation.Field(&a.Value,
            validation.Required,
            validation.Length(1, 5),
            validation.Each(validation.NilOrNotEmpty, validation.In([]string{"true", "false"}),
            ),
        ),
    )
}

This is the request I sent:

{"value":["true"]}

I'm getting this error from In rules:

value: (0: must be a valid value.).

But when I check the value using == and reflect.DeppEqual, the values ​​are equal:

fmt.Println(reflect.DeepEqual([]string{"true", "false"}[0], a.Value[0]))
fmt.Println([]string{"true", "false"}[0] == a.Value[0])


output:
true
true

What am I doing wrong here?

Correct answer

Use validation.Each(validation.In([]string{"true", "false"})) Yes Compares each element in the Value slice to the slice provided to validate.In, i.e. []string{ "true", "false"} .

Use validation.In("true", "false") to compare each element in the Value slice with each value in validate.In Compare.
