validate before publish

[mi32dogs]

Hi is there a way to validate before publish?

For example, I have a dataobject that needs a date before it can be published
But I wand the ability to always be able to save it even without a date.

I haven't tested this, but I suspect that because the reading mode is switched to the appropriate value when saving as draft or publishing, you might be able to do something like this:

class SomeDataObject extends DataObject
{
    // ...

    protected function validate()
    {
        $result = parent::validate();
​
        if (Versioned::current_stage() == 'Live') {
            if (empty($this->Date)) {
                $result->combineAnd(
                    new ValidationResult(false, 'Date cannot be empty when publishing'));
            }
        }

        return $result;
    }
}

This works perfectly, thank you so much
