小编use*_*154的帖子

我有一个像这样的Django模型：

class Sections(models.Model):
    section_id = models.CharField(max_length=127, null=True, blank=True)
    title = models.CharField(max_length=255)
    description = models.TextField(null=True, blank=True)

class Risk(models.Model):
    title = models.CharField(max_length=256, null=False, blank=False)
    section = models.ForeignKey(Sections, related_name='risks')

class Actions(models.Model):
    title = models.CharField(max_length=256, null=False, blank=False)
    section = models.ForeignKey(Sections, related_name='actions')

像这样的序列化器：

class RiskSerializer(serializers.ModelSerializer):
    class Meta:
        model = Risk
        fields = ('id', 'title',)

class ActionsSerializer(serializers.ModelSerializer):
    class Meta:
        model = Actions
        fields = ('id', 'title',)

class RiskActionPerSectionsSerializer(serializers.ModelSerializer):
   risks = RiskSerializer(many=True, read_only=True)
   actions = ActionsSerializer(many=True, read_only=True)

   class Meta:
        model = Sections
        fields = ('section_id', 'risks', 'actions') …
