Creating multiple objects using the same form - django

Question

Hi I have just read through, http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/, and am trying to apply it to my own django app.
I have created a view which lets me use a single form to create and store 2 objects that are related to each other
I am getting a post error but can't seem to find what is causing it.
After clicking add a blank white page is shown along with the error message below, which is in red in the terminal.
'[28/May/2014 02:57:25] "POST /members HTTP/1.1" 405 0'
Models
class MemberRole(models.Model,get_fields):
name = models.CharField(max_length = 20)
def __unicode__(self):
return self.name
class Member(models.Model,get_fields):
first_name = models.CharField(max_length = 20)
role = models.ForeignKey(MemberRole, null = True, blank = True)
Forms
class MemberForm(forms.ModelForm):
class Meta:
model = Member
exclude = ('role',)
class MemberRoleForm(forms.ModelForm):
class Meta:
model = MemberRole
View fucntion
def add_member(request):
model_url = 'member-list'
if request.method == "POST":
rform = MemberRoleForm(request.POST, instance=MemberRole())
mform = MemberForm(request.POST, instance=Member())
if rform.is_valid() and mform.is_valid():
new_role = rform.save()
new_member = mform.save()
return HttpResponseRedirect('member-list')
else:
rform = MemberRoleForm(instance=MemberRole())
mform = MemberForm(instance=Member())
return render_to_response('create_model.html', {'role_form': rform, 'member_form': mform, 'model_url': model_url,},context_instance=RequestContext(request))
snippet of create_model.html
<form action="{% url model_url %}" method="POST">
{% csrf_token %}
{% if model_url == 'member-list' %}
{% for field in member_form %}
<div class="fieldWrapper">
{{ field.errors }}
{{ field.label_tag }} {{ field }}
</div>
{% endfor %}
{% for field in role_form %}
<div class="fieldWrapper">
{{ field.errors }}
{{ field.label_tag }} {{ field }}
</div>
{% endfor %}
{% endif %}
<input id="save_contact" type="submit" value="Add"/>
</form>

I've solved it, it was due to some errors in url naming
View
model_url = 'member-add'
return HttpResponseRedirect('members')
URLS
url(r'^members', ModelListView.as_view(model = Member,page_name = 'Members',edit_link = 'updatemember/'), name='member-list'),
url(r'^addmember', 'inventory.views.add_member', name = 'member-add'),
