Question

您好我在将views.py（objects.all）中的数据传递给我的ajax时遇到了问题。我想要做的是查询集中的每个对象，我会将其细节附加到我的html中的div中。我尝试序列化它，但我在如何循环序列化的JSON方面遇到了麻烦。有什么建议？请帮助。

jQuery

function getOffers(key){
        dict = {
            'key':key// pk value of post sent to retrieve offers to it
        };
        key = "pk";//I actually dont know what to put here
        generateCSRFToken();
        $.ajax({
            url: "/retrieve_offers/",
            method: "POST",
            data : JSON.stringify(dict),
            success: function(data){
                data = JSON.parse(data);
                console.log(data);

                //HOW TO LOOP THROUGH THE DATA AND GET EACH PK
            },
            error: function(){
            }

        })
    }

views.py

def retrieve_offers(request):
    dict = json.loads(request.body)
    post_key = Post.objects.get(pk=dict["key"])
    offers = Offer.objects.filter(post_id=post_key)

    data = serializers.serialize('json',offers)

    return HttpResponse(
        json.dumps(data),
        content_type="application/json"
    )

models.py

class Post(models.Model):
    date_submitted = models.DateField()
    description = models.CharField(max_length=1024)
    author = models.ForeignKey(to=User, on_delete=models.CASCADE)
    category = models.ForeignKey(to=Category,on_delete=models.CASCADE)
    trade_item = models.FileField(null=True,blank=True)
    trade_item_name = models.CharField(null=True,max_length=100)
    receive_item = models.FileField(null=True, blank=True)
    receive_item_name = models.CharField(null=True,max_length=100)

    def __str__(self):
        return str(self.pk) + " by " + (self.author.username)

    @staticmethod
    def create(date_submitted, description, author, category):
        post = Post()
        post.date_submitted = date_submitted
        post.description = description
        post.author = author
        post.category = category
        return post

class Offer(models.Model):
    date_submitted = models.DateField()
    description = models.CharField(max_length=1024)
    author = models.ForeignKey(to=User,on_delete=models.CASCADE)
    post_id = models.ForeignKey(to=Post,on_delete=models.CASCADE)
    image = models.FileField(null=True, blank=True)
    item_name = models.CharField(null=True,max_length=100)

的console.log（数据） here is the console.log result image

序列化JSON的示例结果

'[{"model": "bartr.offer", "pk": 26, "fields": {"date_submitted": "2017-03-30", "description": "asdasd", "author": 38, "post_id": 23, "image": "pexels-photo-167810_7vvcPK4.jpeg", "item_name": "something"}}]'

如何检索模型数据库中的所有对象并通过ajax发送它？
