mongodb - How to run $and operator in mgo query in Golang -

-

i want execute following query in mongodb in golang

check_select = bson.m{             "$and": []interface{}{                 "shr_key": user_shr_key,                 "id": uid,                 "user_history": bson.m{"$elemmatch": bson.m{"action": "stop", "message_id": mid}},             },         }

please help... getting following error "index must non-negative integer constant".

the error way initialize array in go: 

.... "$and": []interface{}{     "shr_key": user_shr_key, ....

go array doesn't accept string index.

anyway, in order solve problem, remove index array initialization , wrap key-value pair in bson.m do, eg:

bson.m{             "$and": []bson.m{ // can try in []interface                 bson.m{"shr_key": user_shr_key},                 bson.m{"id": uid},                 bson.m{"user_history": bson.m{"$elemmatch": bson.m{"action": "stop", "message_id": mid}}},             },         }

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
