我有一个代表工作的类，一个代表描述工作的标签的类，然后我有一个类在它们之间建立关系（连接表），因此工作可以由多个标签描述：

class JobTag(models.Model):
    job = models.ForeignKey(Job, unique=False, related_name='jobtags')
    tag = models.ForeignKey(Tag, unique=False, related_name='Tag_For_Job')

    created_time = models.DateTimeField(auto_now_add = True)
    modified_time = models.DateTimeField(auto_now = True)

    class Meta:
        unique_together = ('job', 'tag',)

    def __unicode__(self):
        return 'Tag '+self.tag.name +' for job '+ self.job.name

然后我有序列化程序：

class TagSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Tag
        fields = ('url','name','badge_pic')
        read_only_fields = ('name','badge_pic')

class JobTagSerializer(serializers.HyperlinkedModelSerializer):
    tag = TagSerializer()
    class Meta:
        model = JobTag
        fields = ('tag',)
        depth=1

class JobSerializer(serializers.HyperlinkedModelSerializer):
    jobtags=JobTagSerializer(many=True)
    class Meta:
        model = Job
        fields = ('url','name', 'employer','jobtags','description')
        read_only_fields …
