Yup: Validating nested schema date objects

[ahummel25]

Is there support for validating child property dates within an object field?

I can't quite get the below example to work properly. The val in the is condition of startDate.day is always undefined so I get an error like endDate.day field must be later than undefined.

Not sure if I can access properties in the when clause such as obj.property.

startDate: yup.object().shape({
    day: yup
        .date()
        .required()
        .when("endDate.day", {
            is: val => val !== null, // val is always undefined
            then: schema => schema.max(yup.ref("endDate.day")) // Also undefined
        }),
    time: yup.date().required()
    }),
endDate: yup.object().shape({
    day: yup
        .date()
        .min(yup.ref("startDate.day")) // Undefined
        .required(),
    time: yup.date().required()
})

Struggling with this too!

I'm also struggling with a weird bug where only the date fields in an object come through as undefined in .test(), maybe related? Did you find a workaround?

@timstallmann I unfortunately did not with my original post. Ended up going a different route outside of the yup schema definition with comparison logic.

You're only finding the date fields undefined within the .test() function?

[timstallmann]

Nope they're coming through as undefined all the way through the Yup pipeline as far as I can tell. I tried both Yup.date() and adding the custom schema validator that's mentioned in the docs using moment. So strange though!

I'm struggling in a similar scenario. I have an object type field and i need to ref the sibling of this field, but from its child. I don't know if this is possible and the docs doesn't explains too much about how to use ref. This equalTo function is from here https://github.com/jaredpalmer/formik/issues/90

originport: Yup.object().shape({
                id: Yup.number().test(
                    "originport",
                    "Campo obrigatório",
                    function test(value) {
                        return !!value
                    }
                )
            }),
destinationport: Yup.object().shape({
                id: Yup.number()
                    .equalTo(Yup.ref("originport.id"), "O destino precisa ser diferente da origem")
                    .test(
                        "destinationport",
                        "Campo obrigatório",
                         value => !!value

                    )
            })

Did anyone manage to do this? I have a nested array of objects that need to validation against one of the top-most fields, which is a date, and manipulate that date (i.e. adding/subtracting days) which obviously requires a ref to be resolved.

Any news about? 😢
