【问题描述】：

我有两个模型组织和部门。我想通过使用 DRF 获取所有与部门相关的特定组织 ID，我该怎么做

class Organization(models.Model):
    name = models.CharField(max_length=30, unique=True)
    description = models.CharField(max_length=100)

class Departments(models.Model):
    name = models.CharField(max_length=30, unique=True)
    description = models.CharField(max_length=100)
    email= models.CharField(max_length=30, unique=True)
    phone=  models.CharField(max_length=30)
    org_linked=models.ForeignKey(Organization)
    user_linked=models.ForeignKey(User)


class OrganizationAndDepartmentSerializer(serializers.ModelSerializer):
        org_department=facilitesntSerializer(many=True)

        class Meta:
            model = facilites
            fields=('org_department',)


class OrganizationAndDepartmentViewSet(viewsets.ModelViewSet):

    serializer_class =OrganizationAndDepartmentSerializer

【解决方案1】：

如果你想要完整的嵌套表示；声明一个嵌套序列化器如下：

class DepartmentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Departments
        fields = ('__all__')

class OrganizationSerializer(serializers.ModelSerializer):
    departments = DepartmentsSerializer(many=True, source='org_linked_set', read_only=True)
    class Meta:
        model = Organization
        fields = (
            'name',
            'description',
            'departments'
        )
