如何在后端表单中设置默认值？

Question

i generated admin in Symfony 1,4. I have there DoctrineChoice. I would like set this list select in action.class.php.

I copied executeNew to action.class.php, but i dont can set default value on load page.

$this->form = $this->configuration->getForm();
$this->news = $this->form->getObject();
$this->form['author_id']->getWidget()->setOption('choices', '2');

doesnt work. Is this possible?

Answer 1

This code should work:

$this->form['author_id']->getWidget()->setDefault(2);

But I have to say that if you want it clean, this code belong to the Form class, not the action.
