javascript - How can I specify an array of objects indexed by a field in Typescript? -

-

i have got far:

testquestions: {     data: [{ admintestid: number,              admintestquestionid: number,              questionuid: string,              subtopidid: number,              title: string }] };

now add in object called datamap. object result of passing data through reduce function:

 testquestions.datamap = data.reduce((rv, v) => {             rv[v.questionuid] = v;             return rv;         }, {});

can telling me how can define (inline) datamap?

testquestions: {     data: [{ admintestid: number,              admintestquestionid: number,              questionuid: string,              subtopidid: number,              title: string }],    datamap: questionuid: string [{ admintestid: number,              admintestquestionid: number,              questionuid: string,              subtopidid: number,              title: string }]

};

i have tried above it's not correct. hope can here.

you close. first lets break out object type own interface clarity.

interface question {     admintestid: number;      admintestquestionid: number;      questionuid: string;      subtopidid: number;      title: string; }

this syntax looking in datamap.

interface questionmap {     [questionuid: string]: question; }

all together.

interface testquestions {      data: question[];     datamap: questionmap; }  var testquestions: testquestions = {     data: [],     datamap: {}, };

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.
