What is the correct indention for pep8 on long lines with argument list and assignment

Question

What is the correct indention for this scenario:

class StorageType(models.Model):
    """ Defining a general typ of storage """

    name = models.CharField(
            max_length=50,
            help_text=_("The name for a storage type. Should be unique")
        )

pep8 complains with

../models.py:68:13: E126 continuation line over-indented for hanging indent
../models.py:70:9: E121 continuation line under-indented for hanging indent

Answer 1

I don't know about the "correct one", but here's my favorite which passes pep8 check:

name = models.CharField(
    max_length=50,
    help_text=_("The name for a storage type. Should be unique")
)

Answer 2

This is one correct indentation:

class StorageType(models.Model):
    """ Defining a general typ of storage """

    name = models.CharField(
        max_length=50,
        help_text=_("The name for a storage type. Should be unique")
        )
