users = [] 
for user in current_permission: 
    receivers = user.group.users.all() 
    for user in receivers: 
     users.append(user) 

if is_group_manager or assignee_from_unmanaged_group: 
    form.responsible.choices = [ 
     (user.id, "{0} ({1})".format(user.details.full_name, user.email))for user in users

set.html

{% block page_block_content %} 
    <form method="POST"> 
     {{ form.csrf_token }} 
     {{ wtf.form_field(form.responsible, class="form-control select2") }} 
{% endblock %}
