获取JSONField的键和值

我想将字典列表的键和值从JSONField传递XHR为JSON。

内容JSONField如下：

[{'q1':'12'},{'q2':'22'},{'q3':'11'}]

我想像上面的列表一样通过它们。

models.py：

class User1(models.Model):
    history = models.JSONField(blank=True, null=True)

class UserForm(ModelForm):
    class Meta:
        model = User1
        fields = '__all__'

views.py：

class ArticleUpdateView(UpdateView):
    model = User1
    template_name = None
    ...
    def get(self, request, *args, **kwargs):
        if request.headers.get('x-requested-with') == 'XMLHttpRequest':
            if request.headers.get('Get-History') == 'History':
                form = UserForm(request.POST or None)
                self.object = self.get_object()    
                
                data = {
                    'history': str(form.fields['history'])
                }

                return JsonResponse(data, safe=False)

结果：

{"history": "<django.forms.fields.JSONField object at 0x109d03080>"}
