Works with Django SVN Rev >= 17204.

Replace

if (field not in self.editable_fields):

with

if (field not in self.editable_fields) and (field not in self.exclude):

to be able to use the 'exclude' property to remove fields from the inline.

It works with Django 1.5.1

darkpixel solution works great.

I removed get_readonly_fields method and used readonly_fields tuple instead.
