<http://stackoverflow.com/questions/31481546/q-promise-and-map-doesnt-change-after-iteration#>
I'm using Q Promises to retrieve data from my redis repository. The problem
I'm having, is that through each iteration, the array object
(localEncounter) I'm using to store data returned from the chained
functions is never updated at each iteration. Previously, I tried to solve
this with a foreach loop and spread but the results were the same.
How should I correct this so that localEncounter is updated at each
iteration, and ultimately localEncounters contains correct data when
returned? Thank you.
var localEncounters = [];
var localEncounter = {};
Promise.all(ids.map(function(id) {
return localEncounter, getEncounter(id, client)
.then(function (encounter) {
encounterObject = encounter;
//set the fields for the return object
localEncounter['encounterid'] = encounterObject[f_id];
localEncounter['screeningid'] =
encounterObject[f_screening_id];
localEncounter['assessmentid'] =
encounterObject[f_clinical_assessment_id];
localEncounter['psychevalid'] =
encounterObject[f_psych_eval_id];
//get screening
return getScreening(encounterObject[f_screening_id],
client);
})
.then(function (screening) {
//set the fields for the return object
localEncounter['screeningbegintime'] =
screening[f_begin_time];
//get assessment
return getAssessment(localEncounter['assessmentid'],
client);
})
.then(function (assessment) {
//set the fields for the return object
localEncounter['assessmentbegintime'] =
assessment[f_begin_time];
//get psycheval
//localEncounters.push(assessment);
return getPsychEval(localEncounter['psychevalid'],
client);
})
.then(function (psychEval) {
//set the fields for the return object
localEncounter['psychevalbegintime'] =
psychEval[f_begin_time];
localEncounters.push(localEncounter);
}
, function (reason) {
console.log(reason); // display reason why the call
failed;
reject(reason, 'Something went wrong creating the
encounter!');
})
})).then(function(results) {
// results is an array of names
console.log('done ');
resolve(localEncounters);
})
