模型

class Category(models.Model):
    title = models.CharField(max_length=50)
    slug = models.SlugField(max_length=50,null=False, unique=True) 
    def __str__(self):
        return self.title

class BlogPostModel(models.Model):
    author = models.ForeignKey(User, on_delete=models.CASCADE,null=True,blank=True)
    category = models.ManyToManyField(Category, related_name= catitems )
    title = models.CharField(max_length=255)
    body = models.TextField()
    slug = models.SlugField(max_length=255,null=False, unique=True)
    background_image = models.ImageField(upload_to= post-images ,blank=True)
    image1 = models.ImageField(upload_to= post-images ,blank=True)
    image2 = models.ImageField(upload_to= post-images ,blank=True)
    created_date = models.DateTimeField(auto_now_add=True)
    def __str__(self):
        return self.title

i 想要显示类别的所有权而不是类别补贴

航天员

class Post航天员(serializers.Model航天员):
    author = serializers.CharField(source= author.email , read_only=True)
    class Meta:
            model = BlogPostModel
            fields = [ author , category , title , body , slug , background_image , created_date ]

这是我的产物:

        "category": [
            1,
            2,
            3
        ],

并希望:

        "category": [
             Category title(1)،
             Category title(2)،
             Category title(3)
        ],
问题回答

您可以单独为此类类别创造序号:

class CategorySerializer(serializers.ModelSerializer):
    
   class Meta:
      model = CategoryModel

如今,你可以把序列号照相机列入后航天器:

class PostSerializer(serializers.ModelSerializer):
    ...
    category = CategorySerializer(many=True)
    ...

也没有忘记做<代码>prefetch_related,以改进您称之为序列器的绩效。
