Issue loading model form in AccessListEditView and AccessListRuleEditView

In the guide the EditView forms are defined as:

class AccessListEditView(generic.ObjectEditView):
    queryset = models.AccessList.objects.all()
    form = forms.AccessListForm

class AccessListRuleEditView(generic.ObjectEditView):
    queryset = models.AccessListRule.objects.all()
    form = forms.AccessListRuleForm

Trying to render the pages an error occur:

TypeError at /plugins/access-lists/access-lists/add/

Checking the inherited class generic.ObjectEditView it seems the variable name for model form should be model_form

Updating the two views in views.py as shown here seems to fix the issue:

class AccessListEditView(generic.ObjectEditView):
    queryset = models.AccessList.objects.all()
-   form = forms.AccessListForm
+   model_form = forms.AccessListForm

class AccessListRuleEditView(generic.ObjectEditView):
    queryset = models.AccessListRule.objects.all()
-   form = forms.AccessListRuleForm
+   model_form = forms.AccessListRuleForm
