requiredIf problem

[fakocher]

Hello everybody,

I created my own requiredIf validator that says an attribute is required if another attribute is true, like the one from Vuelidate.

const requiredIf = (other) => 
{
    return rule({
        name: 'requiredIf',
        test: (value, attribute, model) => {
           return !(isNil(value) || value === '') || !model.get(other)
        },
        data: {other},
    });
};

My problem is, the attribute this rule is set on is not validated if the "other" attribute is changed. To cope with that, I watch the "other" attribute changes and run model.validate(). It works, but it's validating every attribute of the model when it should only validate one, and I have to document this weird behavior for my team.

Is there a way to say in a custom rule that the attribute should be validated when another specific attribute is changed ?

Thanks in advance for your answers. Jeremy

Not currently, but I'd be happy to explore the option to include that. In the meantime, you can pass a parameter name to validate, like this:

model.validate('name');

model.validate(['name', 'other']);

Thank you for your answer. We'll use your solution so not all the fields are validated (the model has lots of fields). Have a good day!
