django modelform property hidden field

I'm manually displaying my formset as a table, with each form being looped over. At the bottom of each form I include the hidden fields like:

{% for hidden in form.hidden_fields %}
    {{ hidden }}
{% endfor %}

But the problem is that I am also including properties in my form like:

class AllocationForm(forms.ModelForm):
    name = forms.CharField(widget=forms.TextInput(attrs={'size': '15'}))

    def __init__(self, *args, **kwargs):
        super(AllocationForm, self).__init__(*args, **kwargs)
        if self.instance:
            self.fields['total_budgeted'] = self.instance.total_budgeted()
            self.fields['total_budgeted_account_percent'] = self.instance.total_budgeted_account_percent()
            self.fields['actual_spent'] = self.instance.actual_spent()
            self.fields['actual_spent_account_percent'] = self.instance.actual_spent_account_percent()
            self.fields['total_budgeted_category_percent'] = self.instance.total_budgeted_category_percent()
            self.fields['actual_spent_category_percent'] = self.instance.actual_spent_category_percent()

    class Meta:
        model = Allocation
        exclude = {'created', 'modified', 'source_account'}

And this works in the sense that I definitely see the properties being called, however they display as nothing so that's another issue.

The problem is when I keep the hidden fields in the template I will get errors such as 'int' object has no attribute 'get_bound_field' and so on depending on the return type of the property/method call.

My question is first: is there a check I can do to see if the field is a property in the template and therefore skip over it? It may have something to do with how I'm using the property since in fact every property is displaying nothing (but I see it callback), so second would be about how to display the properties.
