Django Admin Error: pop-up entry form

[Derek]

Hi

I am using Django 1.5.5.  This error happens while running the dev server.  If I click on the "+" button so I can use the pop-up form to add a new entry to a drop-down list (i.e. FK to another model), I get the following error trace when trying to save that form.

File "/home/derek/.virtualenvs/s2s/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
  115.                         response = callback(request, *callback_args, **callback_kwargs)

  64.     return mark_safe(force_text(value).translate(_js_escapes))

Exception Type: TypeError at /admin/core/item/add/
Exception Value: expected a character buffer object

You can see there are no links to my code, so I am not sure what needs to change or be changed.  Is it Django code itself that is faulty?

Thanks

Solved.  You need to add "u" to the unicode representation of your model's record.  As in:

    def __unicode__(self):

        return u'%s' % self.fieldname

This "error" does not show up in the normal admin page for the model, only when its accessed via the pop-up route.
