Django rest框架了解如何查询关系

[
{
“id”：1，
“地址”：“海得拉巴”，
“雇员”：“本地主机：8000/雇员/1/”，
“职务头衔”：“管理员”，
“employeesomething”：http://localhost:8000/employee/2/"
},
{
“id”：2，
“地址”：“海得拉巴”，
“雇员”：http://localhost:8000/employee/1/",
“职务头衔”：“管理员”，
“employeesomething”：http://localhost:8000/employee/3/"
},
{
“id”：3，
“地址”：“海得拉巴”，
“雇员”：http://localhost:8000/employee/4/",
“职务头衔”：“管理员”，
“employeesomething”：http://localhost:8000/employee/5/"
},
{
“id”：4，
“地址”：“海得拉巴”，
“雇员”：http://localhost:8000/employee/4/",
“职务头衔”：“管理员”，
“employeesomething”：http://localhost:8000/employee/6/"
}
]

在您的视图中：

假设您在

请求中获得
员工id
。数据

models.py

class Employee(models.Model):
    Name = models.CharField(max_length=50 )
    Email = models.CharField(max_length=30)

    def __str__(self):
        return self.Name              # __unicode__ on Python 2



class EmployeeProfile(models.Model):
    employee = models.ForeignKey(Employee, related_name='fromemployee')
    Address = models.CharField(max_length=50, null=True, blank=True)
    job_title = models.CharField(max_length=50, null=True, blank=True)
    employeesomething= models.ForeignKey(Employee, related_name='refirence')

    def __str__(self):              # __unicode__ on Python 2
       return self.Address



serializers.py

class EmployeeSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Employee
        fields = ('id', 'Name')


class EmployeeProfileSerializer(serializers.HyperlinkedModelSerializer):
    # usergroups = serializers.StringRelatedField(many=True)
    employee_set = EmployeeSerializer(many=True, read_only=True)
    class Meta:
        model = EmployeeProfile
        fields = ('id', 'Address','employee','job_title','employeesomething','employee_set')


views.py

class EmployeeViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows groups to be viewed or edited.
    """
    queryset = Employee.objects.all()
    serializer_class = EmployeeSerializer    

class EmployeeProfileViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows groups to be viewed or edited.
    """
    queryset = EmployeeProfile.objects.all()
    serializer_class = EmployeeProfileSerializer        


urls.py

router = routers.DefaultRouter()


router.register(r'employee', views.EmployeeViewSet)
router.register(r'employeeprofile', views.EmployeeProfileViewSet)


urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]


my out put   http://localhost:8000/employeeprofile/

如果您希望使用

EmployeeProfile

而不是其链接，请使用

ModelSerializer

，而不是

HyperlinkedModelSerializer

，谢谢您的建议。当我传递员工id时，我想写一个过滤器。我需要一个与员工关联的员工档案，在我的案例中，员工1在员工档案1,2中。您还需要了解什么？您需要在视图中使用此代码，您如何将“员工id”发送到视图？我是Rest Framework的新手确定您是否可以更明确一些。我得到一个名称“request”未定义错误。谢谢您您发送的是GET或POST方法？我使用的是GETmethod@thisisms我编辑了答案。我希望这能给你一个更好的主意。

from rest_framework.views import APIView
from rest_framework.response import Response
from myapp.serializers import EmployeeProfileSerializer
from myapp.models import EmployeeProfile


class MyView(APIView):

    def get(self, request, *arga, **kwargs)
        e_profiles = EmployeeProfile.objects.filter(employee__pk=request.GET.get('employee_id'))

        # Then call you serializer

        e_serialized = EmployeeProfileSerializer(e_profiles, many=True)
        return Response(e_serialized.data)
