要序列化和反序列化，请使用以下命令:

from django.core import serializers

serial = serializers.serialize("json", [obj])
...
# .next() pulls the first object out of the generator
# .object retrieves django object the object from the DeserializedObject
obj = next(serializers.deserialize("json", serial)).object

使用python格式的Django Serializer，

from django.core import serializers

qs = SomeModel.objects.all()
serialized_obj = serializers.serialize('python', qs)

json和python格式有什么区别?

json格式将以str格式返回结果，而python将以list或OrderedDict格式返回结果

让这是一个农作物序列化器，做如下所示。对我有用，当然对你也有用。

首先导入序列化器

from django.core import serializers

然后你可以这样写

class CropVarietySerializer(serializers.Serializer): 
    crop_variety_info = serializers.serialize('json', [ obj, ])

或者你可以这样写

class CropVarietySerializer(serializers.Serializer): 
    crop_variety_info = serializers.JSONField() 

然后在views.py中调用这个序列化器 详情请访问https://docs.djangoproject.com/en/4.1/topics/serialization/ 序列化器。JSONField(*args， **kwargs)和serializer .JSONField()是相同的。您也可以访问https://www.django-rest-framework.org/api-guide/fields/了解JSONField()的详细信息。

ville = UneVille.objects.get(nom='lihlihlihlih')
....
blablablab
.......

return HttpResponse(simplejson.dumps(ville.__dict__))

我返回我实例的字典

所以它会返回类似{'field1':value，"field2":value，....}

要序列化和反序列化，请使用以下命令:

from django.core import serializers

serial = serializers.serialize("json", [obj])
...
# .next() pulls the first object out of the generator
# .object retrieves django object the object from the DeserializedObject
obj = next(serializers.deserialize("json", serial)).object

如果你正在询问如何序列化一个模型中的单个对象，并且你知道你只会在queryset中获得一个对象(例如，使用objects.get)，那么可以使用如下方法:

import django.core.serializers
import django.http
import models

def jsonExample(request,poll_id):
    s = django.core.serializers.serialize('json',[models.Poll.objects.get(id=poll_id)])
    # s is a string with [] around it, so strip them off
    o=s.strip("[]")
    return django.http.HttpResponse(o, mimetype="application/json")

你会得到这样的东西:

{"pk": 1, "model": "polls.poll", "fields": {"pub_date": "2013-06-27T02:29:38.284Z", "question": "What's up?"}}
