多对多领域中的Django反向关系

我如何得到画廊的回应，如贝娄。现在，galleryserializer只返回带有ID的图像数组的响应。我无法获得图像的详细信息

json响应：

{
    "name": "New Gallery",
    "images": [
        {
             id: 1,
             image: 'url/path/to/image',
             alt_text: 'alt'
        },
        {
             id: 2,
             image: 'url/path/to/image1',
             alt_text: 'alt'
        },
    ]
}

Mymodels.py文件：

class GalleryImage(models.Model):
    image = models.ImageField(upload_to='gallery/')
    alt_text = models.CharField(max_length=300)
    created = models.DateTimeField(auto_now_add=True)

class Gallery(models.Model):
    name = models.CharField(max_length=30)
    slug = AutoSlugField(populate_from='name', unique_with='id')
    images = models.ManyToManyField(GalleryImage, related_name="galleryimages")
    created = models.DateTimeField(auto_now_add=True)

class GalleryImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = GalleryImage
        exclude = '__all__'

class GallerySerializer(serializers.ModelSerializer):
    class Meta:
        model = Gallery
        fields = '__all__'

Myserializers.py文件：

class GalleryImage(models.Model):
    image = models.ImageField(upload_to='gallery/')
    alt_text = models.CharField(max_length=300)
    created = models.DateTimeField(auto_now_add=True)

class Gallery(models.Model):
    name = models.CharField(max_length=30)
    slug = AutoSlugField(populate_from='name', unique_with='id')
    images = models.ManyToManyField(GalleryImage, related_name="galleryimages")
    created = models.DateTimeField(auto_now_add=True)

class GalleryImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = GalleryImage
        exclude = '__all__'

class GallerySerializer(serializers.ModelSerializer):
    class Meta:
        model = Gallery
        fields = '__all__'

使用嵌套序列化

class GallerySerializer(serializers.ModelSerializer):
    images = GalleryImageSerializer(many=True)
    class Meta:
        model = Gallery
        fields = '__all__'

class GallerySerializer（serializers.ModelSerializer）：
图像=GalleryImageSerializer（多个=真）
类元：
模型=画廊
fields='\uuuuu all\uuuuu'

现在我得到了一个错误。排除选项必须是列表或元组。得到str.change

exclude='\uuuuuuuuuuu'

到

fields='\uuuuuuuuuu'

很高兴这有帮助…请也对答案进行投票：）
