如何通过contextprocessor django传递向导变量？

Question

我正在使用带有上下文处理器的两个全局两种形式。

forms.py

    from django import forms

class ContactForm1(forms.Form):    
   subject = forms.CharField(max_length=100)    
   sender = forms.EmailField()
class ContactForm2(forms.Form):
   message = forms.CharField(widget=forms.Textarea)

views.py

from django.http import HttpResponseRedirect
from formtools.wizard.views  import SessionWizardView

class ContactWizard(SessionWizardView):    
   def done(self, form_list, **kwargs): 
     new = MyModel()
     for form in form_list:
            new = construct_instance(form, new, form._meta.fields,   form._meta.exclude)
           new.save()
     HttpResponseRedirect('/page-to-redirect-to-when-done/')

contexprocessors.py

from .forms import ContactForm1, ContactForm2

def contact_form1(request):
    return {
        'contact_form1': ContactForm1()
    }


def contact_form2(request):
    return {
        'contact_form2': ContactForm2(),
    }
