Question

您好我刚读完了http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/，并尝试将其应用到我自己的django应用程序中。

我创建了一个视图，它允许我使用单个表单来创建和存储彼此相关的2个对象

我收到了错误信息，但似乎找不到导致错误的原因。

单击添加后，将显示一个空白页面以及下面的错误消息，该消息在终端中显示为红色。

'[28 / May / 2014 02:57:25]“POST / members HTTP / 1.1”405 0'

模型

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)

表单

class MemberForm(forms.ModelForm):
    class Meta:
        model = Member
        exclude = ('role',)

class MemberRoleForm(forms.ModelForm):
    class Meta:
        model = MemberRole

查看功能

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))

create_model.html的片段

<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>

我已经解决了，这是由于网址命名中的一些错误

查看

model_url = 'member-add'
return HttpResponseRedirect('members')

<强> 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'),

使用相同的表单创建多个对象
