Suppose you have a model

 class User(models.Model):

   TYPES = (
('Admin', 'Admin'),
('Staff', 'Staff'),
  )


 You can access this in the view using the following code

 In your view file

 from app.core.models import User

 def save(request):
     user_types = User.TYPES

    render('user/form.hrml', {user_types:user_types})

If you want to use this variable in the template, Assign that value user_types as a dictionary variable then use the below code
{% for value, text in user_types %}
{{ value }} {{ text }}
{% endfor %}
