Form Type Checkbox Checked for create form SonataAdminBundle

Question

I'm struggling with this problem and can't find the solution. I just moved to SonataAdminBundle today.

I want to make default value as checked for checkbox type but just in form create SonataAdminBundle. In normal Controller, I can define create and edit function with different form value. But in SonataAdminBundle the create and edit form seems just in 1 function :

protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
             ->add('aktif', 'checkbox', array('required' => false))
        ;
    }

I've try add 'attr' => array('checked' => 'checked') but that also happens when editing data.

You can use the function getSubject() in the Admin class to see if you are in the create or edit form.

Something like this:

if (!$this->getSubject()->getId()) {
    // this is the create form
    $attrs = array('checked' => 'checked');
}
else {
    // this is the edit form
    $attrs = array();
}

and you write in options:

'attr' => $attrs

Good luck!
