简介：我有 2 个 Django Rest Framework 模型Patient，并且Embryo只有 1 个用户是超级用户。所有患者都属于超级用户。一个病人可以有很多个胚胎，但每个胚胎只能有一个病人。
我想要做什么：我正在尝试在创建或更新患者模型或胚胎模型时向患者发送电子邮件。下面是我的代码我做错了什么
下面是我的views.py
def send_email_confirmation(instance):
patient = Patient.objects.get(id=instance)
embryo = Embryo.objects.filter(patient=patient)
try:
'''Sending the Order to the patient'''
subject = "Gemonic Prediction Create or Update record"
to = ['{}'.format(patient.email)]
from_email = "no_reply@genomicprediction.com/"
order_information = {
'patient': patient,
'embryo': embryo
}
message = get_template('email/email.html').render(order_information)
msg = EmailMessage(subject, message, to=to, from_email=from_email)
msg.content_subtype = 'html'
msg.send()
except IOError as e:
return e
class PatientsApiView(viewsets.ModelViewSet):
"""Handles Creating, reading and updating Patients"""
serializer_class = serializers.PatientsSerializer
queryset = Patient.objects.all()
authentication_classes = (TokenAuthentication,)
filter_backends = (filters.SearchFilter,)
permission_classes = (IsAuthenticated,)
search_fields = ("first_name", "last_name", "phone", "email",)
def perform_create(self, serializer):
serializer.save(user=self.request.user)
instance = serializer.save()
try:
send_email_confirmation(created=instance)
print('An email has been sent to the customer.')
except IOError as e:
return e
def perform_update(self, serializer):
instance = serializer.save()
try:
send_email_confirmation(modified=instance)
print('An email has been sent to the customer.')
except IOError as e:
return e
class EmbroApiView(viewsets.ModelViewSet):
"""Handles Creating, reading and updating Patients"""
serializer_class = serializers.EmbryoSerializer
queryset = Embryo.objects.all()
authentication_classes = (TokenAuthentication,)
filter_backends = (filters.SearchFilter,)
permission_classes = (IsAuthenticated,)
search_fields = ("code_name", "karyotype", "sex", "down_syndrome",)
def perform_create(self, serializer):
serializer.save(pk=self.kwargs.get("pk"))
instance = serializer.save()
try:
send_email_confirmation(created=instance)
print('An email has been sent to the customer.')
except IOError as e:
return e
def perform_update(self, serializer):
instance = serializer.save()
try:
send_email_confirmation(modified=instance)
print('An email has been sent to the customer.')
except IOError as e:
return e
我的模型在下面以防万一
