TypeError: 'module' object is not callable

[db_333]

Hi,

I am new to Django and am trying to create a simple form around an
existing database (I'm using 1.0). The Model I have looks like this:

class Units(models.Model):
serial_number = models.CharField(max_length=25, primary_key=True)
build = models.CharField(max_length=50, blank=True)
model = models.CharField(max_length=20, blank=True)
create_date = models.DateField(null=True, blank=True)
source = models.CharField(max_length=20, blank=True)
class Meta:
db_table = u'units'

In my view, I created this function:
def save_unit(request):
if request.method == 'POST':
form = UnitFormSave(request.POST)
if form.is_valid():
unit = Units.objects.create(
serial_number = form.clean_data['serial_number'],
build = form.clean_data['build'],
model = form.clean_data['model'],
source = form.clean_data['source'])
unit.save(force_insert=True)
return HttpResponseRedirect('/search/')
else:
form = UnitFormSave()

variables = RequestContext(request, {
'form': form
})
return render_to_response('unit_save.html', variables)

The form:
class UnitFormSave(forms.Form):
serial_number = forms.CharField(max_length=50)
build = forms.CharField(max_length=50)
model = forms.CharField(max_length=10)
source = forms.CharField(max_length=10)

Unfortunately I getting this error and can't seem to get any detail
from some of the debugging. I know the answer is probably right in
front of me, but I can't see where I went wrong. I'm getting this
error from the server output:

Traceback (most recent call last):

The issue is with something in your middleware, specifically you have something in your MIDDLEWARE setting that doesn't point to an actual class.

But what Middleware do you have installed - whats the settings.py
value for middleware?

It looks like that might be problem, none of the above code.

[db_333]

here's what I have for the Middleware:

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.models'
)
I'm searching the APIs to see what I might be missing... any
pointers?

[Alex Gaynor]

Why did you add 'django.contrib.auth.models' to your middleware?  That's whats causing your issue, but what were you hoping to accomplish?

[db_333]

I wanted to later implement a login based on a user session, and I got
some guidance from pretty decent Django book on learning to build
websites with Django. However, I can see that I need to better
understand how the middleware APIs work before I jump ahead.
I appreciate your quick responses

Is there any way to tell through debugging if there's an issue with saving a record?  This form seems to work fine, but the record does not save.  I'm lost as to why it's not committing.  Any pointers on debug statements for this kind of issue?
