json - Django 如何使用 SplitJSONWidget 保存/编辑 json

Question

我正在使用 Django 1.9 library如下:

模型.py:

class Policy(models.Model):
    config = JSONField(max_length=50000, blank=True)
    name = models.CharField(max_length=200, blank=False, unique=True, default="")

    def __unicode__(self):
        return self.name

表单.py:

class PolicyForm(forms.ModelForm):
    class Meta:
        model = Policy
        fields = ('name',)

    attrs = {'class': 'special', 'size': '25'}
    data = forms.CharField(widget=SplitJSONWidget(attrs=attrs, debug=True))

views.py:

def policy_new(request):
    json = {
        "all": {
            "active": True
        }
    }
    if request.method == "POST":
        form = PolicyForm(request.POST)
        if form.is_valid():
        post = form.save(commit=False)
        post.config = form.data
        post.save()
        return redirect('ui:config-list')
    else:
        form = PolicyForm(initial={'data': json})

    template = 'api/policy_template.html'
    context = RequestContext(request, {'form': form})
    return render_to_response(template, context)


def policy_edit(request, pk):
    policy = get_object_or_404(Policy, pk=pk)
    if request.method == "POST":
        form = PolicyForm(request.POST, instance=policy)
        if form.is_valid():
           post = form.save(commit=False)
           post.config = form.data
           post.save()
           return redirect('ui:config-list')
    else:
        form = PolicyForm(instance=policy, initial={'data': policy.config})
    return render(request, 'api/policy_template.html', {'form': form})

我在保存和编辑 json 时遇到问题:

保存:

第一次编辑:

第二次编辑:

如您所见，json 与其自身连接并将 crf token 和名称添加到 json(wtf？)。保存和编辑功能有什么问题？

问题出在保存过程中，解决方案是:

post = form.save(commit=False)
post.config = form.cleaned_data['data']
post.save()

在policy_new()和policy_edit()函数中。
