This works for me ...

def get_verbose_name(obj, field):
"""New _meta API with Django 1.8"""
return
obj.__class__()._meta.get_field('{0}'.format(field)).verbose_name

So then you can call get_verbose_name with the instance of whatever
object you want plus the actual field name to get the verbose_name
declared in the model.
