Symfony2, How to edit fields in a form and avoid empty password field

Question

I have a problem whenever I want to edit fields of a form such as (name,username,email..) the password field goes empty in the database. what should I do I want to keep it the same (I don't want to change it) I want to be able to edit only the fields I choose.

PS:I was facing this problem also with username field but I managed to solve it by making it 'read only' but I couldn't do the same with the password field. And the fields belongs to 2 different entities User and Developper. I will share the TWIG(form edit) , formBuilder(UserType), and UserController

You can remove the fields you don't want to edit from your UserType class or build another formType class to use in your editAction.

For example, without the password field :

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('email', 'email', array(
                'label'=>'Email *', 
                'attr'=>array('class'=>'form-control',
                          'onchange'=>'check_email(value)'),
                'label_attr'=>array('class'=>'label-control red')))
            ->add('username', 'text', array(
            'label'=>"Identifiant *", 
            'attr'=>array('class'=>'form-control',
                          'onchange'=>'check_username(value)'),
            'label_attr'=>array('class'=>'label-control red')))
            ->add('soldecongeannuel', 'integer', array(
            'label'=>"Solde congé annuel *", 
            'attr'=>array('class'=>'form-control',
                          'onchange'=>'check_username(value)'),
            'label_attr'=>array('class'=>'label-control red')))
            ->add('soldemaladie', 'integer', array(
            'label'=>"Solde maladie *", 
            'attr'=>array('class'=>'form-control',
                          'onchange'=>'check_username(value)'),
            'label_attr'=>array('class'=>'label-control red')))
            ->add('soldeautremotif', 'integer', array(
            'label'=>"Solde autre motif *", 
            'attr'=>array('class'=>'form-control',
                          'onchange'=>'check_username(value)'),
            'label_attr'=>array('class'=>'label-control red')))
        ;
    }

You should also take a look to the symfony form documentation, especially the rendering part, and adapt your twig accordingly to ensure all your fields are correctly rendered.
