How to validate images outside of blocks.

[Tom-revere]

I have an image field I want to make required. As it is outside of a block, I am adding this to the Request.php file

public function rulesForUpdate()
{
    return [
        'article_tile_image' => 'required'
    ];
}

However when saving, I get this error

422 Unprocessable Content

Is there any way to validate media fields outside of a block?

Thanks

Hey @Tom-revere,

You can use the following (replace cover with your field name).

    public function rulesForUpdate()
    {
        return ['medias.cover' => 'required|array|min:1'];
    }
