Grpc Conversion issue from RepeatedCompositeContainer to dict
问题
"RepeatedCompositeContainer"
关于这个，我有一个问题
"google._upb._message.RepeatedCompositeContainer" 对象没有属性 "file"
这个错误出现了
我写了这段代码
convert_dict = MessageToDict(user.results, descriptor_pool=True)
我想将 "RepeatedCompositeContainer" 转换成字典，但是出现了错误，如你所见
我期望将 "RepeatedCompositeContainer" 转换成字典
英文:
RepeatedCompositeContainer
About This I have one question
google._upb._message.RepeatedCompositeContainer' object has no attribute 'file'
this error is coming
I have write this code
convert_dict = MessageToDict(user.results, descriptor_pool=True)
i want to convert RepeatedCompositeContainer into the dict and this is throwing me error as you see
i am expecting to convert RepeatedCompositeContainer to dict

foo.proto:
语法 = "proto3";
包 foo;
消息 X {
重复 字符串 words = 1;
}
和:
protoc \
--proto_path=${PWD} \
--python_out=${PWD} \
--pyi_out=${PWD} \
${PWD}/foo.proto
main.py:
from google.protobuf.json_format import MessageToDict
from foo_pb2 import X
x = X()
x.words.extend(["A","B","C"])
print(x)
# 正确（成功）
try:
d=MessageToDict(x)
print(d["words"])
except AttributeError:
pass
# 不正确（失败）
try:
d=MessageToDict(x.words)
print(d)
except AttributeError:
print("无法将消息字段转换为字典")
产生的输出：
words: "A"
words: "B"
words: "C"
['A', 'B', 'C']
无法将消息字段转换为字典
英文:
For example:
foo.proto:
syntax = "proto3";
package foo;
message X {
repeated string words = 1;
}
And:
protoc \
--proto_path=${PWD} \
--python_out=${PWD} \
--pyi_out=${PWD} \
${PWD}/foo.proto
main.py:
from google.protobuf.json_format import MessageToDict
from foo_pb2 import X
x = X()
x.words.extend(["A","B","C"])
print(x)
# Correct (succeeds)
try:
d=MessageToDict(x)
print(d["words"])
except AttributeError:
pass
# Incorrect (fails)
try:
d=MessageToDict(x.words)
print(d)
except AttributeError:
print("unable to convert Message Field to dict")
Yields:
words: "A"
words: "B"
words: "C"
['A', 'B', 'C']
unable to convert Message Field to dict

以下是你要翻译的代码部分：
user.proto
syntax = "proto3";
package user_proto;
import "google/protobuf/empty.proto";
service UserController {
rpc List(UserListRequest) returns (UserListResponse) {}
}
message User {
int32 id = 1;
string name = 2;
string email = 3;
string groups = 4;
}
message UserListRequest {
}
message UserListResponse {
repeated User results = 1;
}
userprotoserializer
from config_routing.models import User
from django_socio_grpc import proto_serializers
from config_routing.grpc import config_routing_pb2
class UserProtoSerializer(proto_serializers.ModelProtoSerializer):
class Meta:
model = User
proto_class = user_pb2.User
proto_class_list = user_pb2.UserListResponse
fields = '__all__'
server.py
def List(self, request, context):
user = User.objects.using('secondary').all()
serializer = UserProtoSerializer(user, many=True)
print(serializer)
return serializer.message
client.py
stub = user_pb2_grpc.UserControllerStub(self.channel)
user = stub.List(user_pb2.UserListRequest())
convert_dict = MessageToDict(user)
print(convert_dict["result"])
this shows me error
AttributeError: file
