我正在将请求的用户对象发送到后台任务,该任务负责获取该用户的个人资料,然后计算个人资料的完整性。我可以发送序列化的用户对象,但无法获取该用户的配置文件。我该怎么办?
consumers.py
class AccountBackgroundTasks(SyncConsumer):
def calculate_profile_percentage(self, context):
print("arrived here successfully")
logger.info("context", context)
weight = {'full_name': 10, 'age': 10, 'city': 10, 'address': 10}
total = 0
try:
user = context.get('user')
profile_instance = model_to_dict(Profile.objects.get(user=user))
for field in profile_instance:
try:
total += weight[field]
except AttributeError:
logger.error("Could not find the field")
continue
except Profile.DoesNotExist:
logger.error("Profile does not exist")
return
return total
query.py
@staticmethod
def resolve_profile(self, info, **kwargs):
print('info', info.context.user)
# type <class 'apps.accounts.models.User'>
print('type', type(info.context.user))
if info.context.user.is_authenticated:
channel_layer = get_channel_layer()
print("channel_layer", channel_layer)
async_to_sync(channel_layer.send)('accounts', {
'type': 'calculate.profile.percentage',
'text': serializers.serialize('json', [info.context.user, ])
})
return Profile.objects.get(user=info.context.user)
return None

最好只是发送用户的pk并从使用者的db中检索它,因为这是一条跨进程传递的消息,并且尝试序列化模型对象不是一个好主意
