c# - MongoDb Search in Document's Collection returns only fully matched result - Why? -

-

i'm trying locate user username , password match. have office collection each office document contains many users

var builder = builders<mnoffice>.filter;              var filter = builder.anyeq(o => o.users, new officeuser()             {                 username = username,                 password = password             });             var office = await offices.find(filter).firstordefaultasync().configureawait(false);             return office;

the above query returns null. although should result back. officeuser class has 3 properties, username, password, , name. mongo forces me 3 properties match in query, want have 2 properties matching (usename , password) in order result back, how can accomplish that? no documentation that.

thanks!

 var filter = builder.elemmatch(o => o.users, user => user.username == username && user.password == password);

solved using elemmatch, still dont understand logic behind first attempt.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
