Python django restframework HyperlinkedRelatedField在一对多和多对多关系上返回空值

嗨，我是django restframework的新手，我有这样的模型：

class Tag(models.Model):
    name = models.CharField(max_length=10)

    def __str__(self):
        return self.name

class Blog(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE,null=True,related_name='post')
    tags = models.ManyToManyField(Tag,related_name='tag')

    def __str__(self):
        return self.title

我的观点是（如果它看起来很糟糕，我很抱歉）：

这是我的序列化程序：

class BlogSerializers(serializers.ModelSerializer):
    author = serializers.HyperlinkedRelatedField(
        read_only=True,
        view_name='user-detail'
    )

    tags = serializers.HyperlinkedRelatedField(
        many = True,
        read_only=True,
        view_name='tag-detail'
    )
    class Meta:
        model = Blog
        fields = ('id','title','content','author','tags')

class UserSerializers(serializers.ModelSerializer):
    post = serializers.HyperlinkedRelatedField(
        many=True,
        read_only=True,
        view_name='blog-detail'
    )

    class Meta:
        model = User
        fields = ('id','username','email','first_name','last_name','post')

class TagSerializers(serializers.ModelSerializer):
    class Meta:
        model = Tag
        fields = ('id','name')

我的网址：

path('user/<int:pk>',views.userDetail,name="user-detail"),
path('blog/create',views.insertPost,name="blog-new"),
path('blog/',views.blogList,name="blog-list"),
path('blogs/<int:pk>',views.userBlog,name="blog-detail"),
path('tags/<int:pk>',views.tagDetail,name="tag-detail"),

这是我不使用超链接LatedField的时候

{
        "id": 10,
        "title": "Ubuntu",
        "content": "TEST",
        "author": null,
        "tags": []
}

{
    "id": 11,
    "title": "Ubuntu",
    "content": "TEST",
    "author": 2,
    "tags": [
        1,
        3
    ]
}

那么，我们如何修复它呢？我的代码哪里出错了？提前谢谢

我正在做类似的工作，如果我发现了什么，我会告诉你的。

{
    "id": 11,
    "title": "Ubuntu",
    "content": "TEST",
    "author": 2,
    "tags": [
        1,
        3
    ]
}
