python - Django - 序列化 parent 协会

Question

我正在尝试从一对多关系创建一个序列化的 RESTful 响应。

我有一张表Lexicon，主键lexicon_id，我还有一张表lexicon_attributes，主键lexicon_attribute_id，外键lexicon_id

class Lexicons(models.Model):
    """
    Holds all words
    """
    lexicon_id = models.BigIntegerField(primary_key=True)
    word = models.TextField(blank=True, null=True)
    date_created = models.DateTimeField(blank=True, null=True)
    date_modified = models.DateTimeField(blank=True, null=True)

    class Meta:
        managed = True
        db_table = 'lexicons'

class LexiconAttributes(models.Model):
    class Meta:
        managed = True
        db_table = 'lexicon_attributes'

    lexicon_attribute_id = models.AutoField(primary_key=True)
    lexicon_id = models.ForeignKey('Lexicons', db_column='lexicon_id', related_name="lexicon_attributes")
    is_verb = models.CharField(max_length=1, blank=True, null=True)
    is_plural = models.CharField(max_length=1, blank=True, null=True)
    is_past_tense = models.CharField(max_length=1, blank=True, null=True)

序列化器

class LexiconAttributesSerializer(serializers.ModelSerializer):
    class Meta:
       model = LexiconAttributes 
       fields = '__all__'  

class LexiconsSerializer(serializers.ModelSerializer):
    lexicon_attributes = LexiconAttributesSerializer(source='*', many=False)
    class Meta:
        model = Lexicons

当我请求/lexicons/2/时

{
“lexicon_id”:2，
“词典属性”:{
“lexicon_id”:2
},
“字”:“电脑”，
“创建日期”:“2015-07-30T20:29:19Z”，
“修改日期”:“2015-07-30T20:29:19Z”
}
如何获取 lexicon_attributes 表中的其他字段

仅供引用，我进入 Django 的第二周，我的应用程序最初是在 Cakephp3 中完成的

Answer 1

类 LexiconsSerializer(序列化器.ModelSerializer):
lexicon_attributes = LexiconAttributesSerializer()
类元:
模型 = 词典
字段 = '__all__'
