django get default model field value

Question

I want to write a view to reset some model field values to their default. How can I get default model field values?

class Foo(models.Model):
    bar_field = models.CharField(blank=True, default='bar')

so what I want is:

def reset(request, id):
    obj = get_object_or_404(Foo, id=id)
    obj.bar_field = # logic to get default from model field
    obj.save()
    ...

Since Django 1.10: myfield = Foo._meta.get_field('bar_field').get_default()

myfield = Foo._meta.get_field_by_name('bar_field')

and the default is just an attribute of the field:

myfield.default

Actually it's myfield = Foo._meta.get_field('bar_field') but you point me to the right direction. Thank you. – Goran Sep 20 '16 at 14:03
