Django form wizard save data into PostgreSQL

I'm creating two form using form wizard.

When the user finish fill in the first form(personal details), then select next button, it will go to second form(family member's details).

When the user select submit button, the data will save into specific table(Details and Family). My database engine is PostgreSQL.

Here is my code in view:

FORMS = [("customer", CustomerForm),
         ("family", FamilyForm)]

TEMPLATES = {"customer": "customer_register.html",
             "family": "family_register.html",}

def cust_contact_register(wizard):
    cleaned_data = wizard.get_cleaned_data_for_step('customer') or {'method': 'none'}
    return cleaned_data['method'] == 'family'

class CustWizard(SessionWizardView):
    template_name = 'customer_register.html'
    # def get_template_names(self):
    #     return [TEMPLATES[self.steps.current]]

    def done(self, form_list,form_dict,**kwargs):
        form_data= [form.cleaned_data for form in form_list]
        for form in form_data:
            name = form['name']   ## I want to get the data here to save nto database but it return error.
            mobile = form['mobile']
            email = form['email']
            familyname = form['familyname']
            address = form['address']
        add_member = Customer(
            name=name,
            mobile=mobile,
            email=email,
        )
        add_family = Family(
            famname=famname,
            address=address,
        )
        add_member.save()
        add_family.save()
        return render(self.request, 'customer_register.html', {
            'form_data': form_data,
        })

Customer table have id,name,mobile,email,and familyid(Foreign Key) attribute where Family table have id,name and address attribute.

The error returned:

Traceback:

Exception Type: KeyError at /customer/register/
Exception Value: 'name'

But when i tried this in customer_register.html, the data can be display:

{% for form in form_data %}
    Name: {{ form.name }}
    Mobile: {{ form.mobile }}
    email: {{ form.email }}
    ......
{% endfor %}

UPDATED

class CustomerForm(forms.Form):
    name = forms.CharField(max_length=50,required=True)
    mobile = forms.CharField(max_length=50,required=True)
    email = forms.EmailField(max_length=50,required=True)

class FamilyForm(forms.Form):
    famname = forms.CharField(max_length=50,required=True)
    address = forms.CharField(max_length=50,required=True)
