如何在 Django Rest Framework 中通过电子邮件发送动态数据

Question

我正在尝试编写一个在文件上传后发送通知电子邮件的函数。 如果我对“发送到”电子邮件地址进行硬编码，则我的以下代码有效。

def perform_create(self, serializer):
        serializer.save(owner=self.request.user)
        from_email = self.request.user.email
        send_mail('New Files have been Uploaded',
                  'New files have been uploaded.',
                  from_email,
                  ['sendto@email.com', ],
                  fail_silently=False)

我需要根据序列化程序中的 editor_email 动态设置“sendto@email.com”。 下面是序列化器。

class VideoSerializer(serializers.ModelSerializer):
    projectName = serializers.SerializerMethodField(allow_null=True)
    editor_email = serializers.EmailField(
        source='editor.email', required=False)

    class Meta:
        model = Video
        # fields = '__all__'
        fields = [
            'url',
            'handle',
            'filename',
            'size',
            'source',
            'uploadId',
            'originalPath',
            'owner',
            'project',
            'uploadDate',
            'editor',
            'projectName',
            'editor_email'
        ]

    def get_projectName(self, obj):
        return obj.project.projectName

当我在应用程序的前端检查 JSON 响应时，“editor_email”的值正是我所期望的。

我对 Django Rest Framework 比较陌生，这里一定有我遗漏的东西。 我花了几个小时阅读文档并尝试不同的东西，但似乎没有任何效果。

请问，有人可以告诉我如何根据序列化程序设置此电子邮件吗？

从views.py删除邮件发送代码片段并将其移动到serilizers中

# views.py
def perform_create(self, serializer):
    serializer.save(owner=self.request.user)
     
   
     from_email = self.request.user.email send_mail('New Files have been Uploaded', 'New files have been uploaded.', from_email, ['sendto@email.com', ], fail_silently=False) 
   


# serializers.py
class VideoSerializer(serializers.ModelSerializer):
    # your code


    def send_dynamic_mail(self, video_instance): from_email = video_instance.owner.email send_mail('New Files have been Uploaded', 'New files have been uploaded.', from_email, [video_instance.editor.email, ], fail_silently=False) def create(self, validated_data): video_instance = super().create(validated_data) self.send_dynamic_mail(video_instance) return video_instance

我认为您可以在您的函数中获取字段editor_email数据。 如果它只是字符串数据，那么你可以这样做：

def perform_create(self, serializer):
        serializer.save(owner=self.request.user)
        to_email = serializer.data['editor_email']

        if to_email:
            from_email = self.request.user.email
            send_mail('New Files have been Uploaded',
                      'New files have been uploaded.',
                      from_email,
                      [to_email, ],
                      fail_silently=False)
