我有一个 django 应用程序，模型中有一个 json 字段，看起来像这样
from json_field import JSONField
from django.db import models
class C(models.Model):
name = models.CharField(max_length=255)
jf = JSONField(null=False)
有一个表格显示如下
class Edit(forms.Form):
name = forms.CharField()
def __init__(self, *args, **kwargs):
if 'extra' in kwargs:
extra = kwargs.pop('extra')
super(Edit, self).__init__(*args, **kwargs)
for k, v in extra.iteritems():
self.fields['%s' % k] = v
else:
super(Edit, self).__init__(*args, **kwargs)
该视图将加载 json 字段 jf 并将其作为初始数据发送到表单，并将所有必要的字段作为额外字段发送。
def edit_model(request, pk):
obj = get_object_or_404(models.C, pk=pk)
initial = model_to_dict(obj)
form = Edit(request.POST or None, initial=initial, extra=initial['jf'])
if request.method == 'POST':
if form.is_valid():
.....
# what is the best practice here ?
# intersect cleaned data with the jf fields ?!
# have an external entity that does this ?!
# is anything built into django that can help
谢谢！
