我在models.py中有三个表：

class literature_info(models.Model):
    pmid = models.CharField(primary_key=True,max_length=25)
    publication = models.CharField(max_length=50, blank=True, null=True)
    def __str__(self):
        return self.pmid
    
class dataset_info(models.Model):
    dataset_id = models.CharField(primary_key=True,max_length=25)
    literature = models.ManyToManyField(literature_info, through='literature_dataset', blank=True)
    def __str__(self):
        return self.dataset_id

class literature_dataset(models.Model):
    literature_info = models.ForeignKey(literature_info, on_delete=models.CASCADE)
    dataset_info = models.ForeignKey(dataset_info, on_delete=models.CASCADE)

字符串
当我尝试从dataset_info表中访问文学id时，我会像这样序列化字段：

class literature_info_serializer(serializers.ModelSerializer):
    class Meta:
        model = literature_info
        fields = "__all__"

class dataset_literature_serializer(serializers.ModelSerializer):
    literature = literature_info_serializer(many=True)
    class Meta:
        model = dataset_info
        fields = ('dataset_id','literature',)

它工作得很好，我通过数据集获得了文献信息。
现在我想从literature_info表中获取文献的数据集，我尝试像这样序列化该字段：

class dataset_info_serializer(serializers.ModelSerializer):
    class Meta:
        model = dataset_info
        fields = ('dataset_id',)

class literature_dataset_serializer(serializers.ModelSerializer):
    dataset_info = dataset_info_serializer(many=True)
    class Meta:
        model = literature_info
        fields = ('pmid', 'dataset_info',)

不过，这次不行了。那么我该如何解决这个问题呢？
