I have a little problem with my function, one of the params that I want to set I'm getting from the http request. The problem is that the final data from method below is recalculated in one of the components, and when it happens the result of request is still null. When the response come it's not triggering onChanges
so I can't recalculate this data again, and doCheck
triggering "too often".
updateData(componentRecords: ComponentRecord[], importSourceGroup?: ImportSource[], isImportSource = false, component: DiaryNode = null) {
const recordData = [];
const records = isImportSource ? importSourceGroup : componentRecords;
for (const record of records) {
const recordRow: any = record.ID === 'addingRow' ? record : {
ID: record.ID,
InputTypeID: record.InputTypeID,
SubRecords: record.SubRecords,
attachmentField: record.Fields ? record.Fields.find(({Type}) => Type === DiaryFieldType.ATTACHMENT) : null,
documentsFolder: null,
DateUpdated: null,
ComponentInstanceID: null,
linkedUnits: {},
recordRef: record
};
if (record.ID !== 'addingRow') {
if (isImportSource) {
recordRow.DateUpdated = (record as ImportSource).DateUpdated;
recordRow.ComponentInstanceID = (record as ImportSource).ComponentInstanceID;
}
if (recordRow.attachmentField && recordRow.attachmentField.Value) {
this.subManager.add(this.documentsApiService
.getFileDetailsByFolderID(recordRow.attachmentField.Value)
.subscribe((documents: DocumentsFolder) =>
recordRow.documentsFolder = documents));
}
if (record.Fields) {
for (const field of record.Fields) {
const label = field.Label;
recordRow[label] = field.Type === DiaryFieldType.INTEGER ? parseInt(field.Value, 10) : field.Value;
const schema = component && component.Schema && component.Schema.find(diaryFormField => diaryFormField.Label === label);
if (schema && schema.LinkedUnit) {
recordRow.linkedUnits[label] = schema.LinkedUnit.Attributes.List.PickListItems[0].Label;
}
}
}
}
recordData.push(recordRow);
}
return recordData;
}
The part that is async is
if (recordRow.attachmentField && recordRow.attachmentField.Value) {
this.subManager.add(this.documentsApiService
.getFileDetailsByFolderID(recordRow.attachmentField.Value)
.subscribe((documents: DocumentsFolder) =>
recordRow.documentsFolder = documents));
}
So I don't know what is the best solution for this but I was wondering if it's possible to wait here for the response, and go furthure when it comes.
What do you think?
