Silverstripe根据页面类型设置不同的默认值

Question

I have a default value set in $db array to "1". For ex :

class Page extends SiteTree {
   public static $defaults = array(
      "Indexing" => "1"
   );
}

This works fine and sets the default value very nicely. Now I have a different page type say for example :

 class mypage extends page{
    // Since this class extends page so it will take the default
    // value "Indexing" => "1" ..
 }

I want to set the default value "Indexing" => "0" in the "mypage" page type. How can I achieve that.

I have tried the following :

 class mypage extends page{
    public static $defaults = array(
      "Indexing" => "0"
    );
 }

This does not work as the parent default value is set. Any help would be deeply appreciated. Thanks.

@Zauberfisch is almost to the point but I think he missed something. You must use :

public function populateDefaults(){
    if($this->ClassName == "mypage")
        $this->PGIndexing = "0";
    else
        $this->PGIndexing = "1";
}

Here you are setting the default value based on the classname. So this should work. Cheers :)
