Empty cleaned_data

Question

I am not understanding why this is happening. I have apply the exact same code to other inline formsets but this specific inline formset is not saving any of my changes. I found that within my form "AtLeastOneFull" that form.cleaned_data is always empty despite that I have data.

The webpage displays the contents of model 'Access' correctly, but once I click submit, it registers as invalid because I have no data regardless of the changes I make to the inline form's data on the web page.

forms:

class AtLeastOneFull(forms.models.BaseInlineFormSet):
    def clean(self):
        count = 0
        for form in self.forms:
            try:
                if form.cleaned_data and not form.cleaned_data.get('access_rights', ACCESS_CHOICES[0][0]):
                    count += 1
                    assert False
            except AttributeError:
                pass
        if count < 1:
            raise forms.ValidationError('You must have at least one full access user')

class UserAccessForm(forms.ModelForm):
    class Meta:
        model = Access
    def clean(self):
       cleaned_data = self.cleaned_data
       # Check 1: Must have valid user.
       # To Be Developed
       return cleaned_data

models:

class Portfolio (models.Model):
    nickname = models.CharField(max_length=20, unique=True)
    name = models.CharField(max_length=50, unique=True)
    address1 = models.CharField(max_length=75, null=True, blank=True) #Street address, P.O. box, company name, c/o
    address2 = models.CharField(max_length=75, null=True, blank=True) #Apartment, suite, unit, building, floor, etc.
    city = models.CharField(max_length=30, null=True, blank=True)
    state = models.CharField(max_length=2, null=True, blank=True)
    zip = models.CharField(max_length=10, null=True, blank=True)

    def __unicode__(self):
        return u'%s' % (self.nickname)

    class Meta:
        ordering = ['name']

# Property Expansion
class Access (models.Model):
    portfolio_id = models.ForeignKey(Portfolio)
    user_id = models.ForeignKey(User)
    title = models.CharField(max_length=30, null=True, blank=True)
    access_rights = models.PositiveIntegerField(choices=ACCESS_CHOICES)

    def __unicode__(self):
        return u'%s: %s' % (self.portfolio_id, self.user_id)

    class Meta:
        ordering = ['portfolio_id', 'user_id']
        unique_together = ("portfolio_id", "user_id")

view:

cPortfolio = Portfolio.objects.get(nickname=pNickname)
AccessFormSet = inlineformset_factory(Portfolio,
                                      Access,
                                      form=UserAccessForm,
                                      formset=AtLeastOneFull,
                                      extra=1,
                                      can_delete=False)
if request.method == 'POST':
    if 'access_apply' in request.POST:
        cAccessFormSet = AccessFormSet(request.POST, request.FILES, instance=cPortfolio)
        if cAccessFormSet.is_valid():
            testResults  = cAccessFormSet.save(commit=False)
            for form in testResults:
                form.save()
cAccessFormSet = AccessFormSet(instance=cPortfolio)

Answer 1

Surely it's not as simple as removing the assert False statement in AtLeastOneFull.clean?

Also, why is UserAccessForm.clean querying Users by "Username", when the model field is actually user_id?
