複雑で複雑な（コードではない）ファクトリコールをAngularで使用すると、thenプロパティまたはsuccessCallbackを実行するために使用できるものが返されません方法（エラー自体はTypeError: Cannot read property 'then' of undefinedです）。何が原因か分かりませんが、Webサービスへの複数の入れ子になった$ http.post呼び出しのような、呼び出しの固有のコンポーネントがいくつかあります。未定義の値/約束を返すファクトリ定義のメソッドへの呼び出し
updateDocument: function(documentId, newFileData, appointmentFileName = null, appointmentCategory = null, appointmentId = null) {
//Get Existing Document Details (including Revision)
//document.
documentsService.documentsFactory.getDocumentRecordById(documentId).then(
function successCallback(response) {
console.debug("Response", response);
var NextRevision = parseInt(response.data.revision) + 1;
if ((appointmentCategory === null) || (appointmentCategory === undefined)) {
appointmentCategory = response.data.category_id;
}
if ((appointmentId === null) || (appointmentId === undefined)) {
var ErrorObj = {
status: 10,
message: 'Appointment ID not defined.'
};
return ErrorObj;
}
if ((appointmentFileName === null) || (appointmentFileName === undefined)) {
appointmentFileName = response.data.filename;
}
if ((newFileData === null) || (newFileData === undefined)) {
var ErrorObj = {
status: 11,
message: 'File Data not defined.'
};
return ErrorObj;
}
var action = 'set_document_revision';
var endpoint = cfg.url;
var sessionId = systemService.sessionService.getSessionId();
var DocRevObj = {
session: sessionId,
document_revision: {
id: documentId,
file: newFileData,
filename: appointmentFileName,
revision: NextRevision
}
};
var DocNodeObj = {
session: sessionId,
module: "Documents",
name_value_list: [{
name: 'document_name',
value: appointmentFileName
}, {
name: 'category_id',
value: appointmentCategory
}, {
name: 'id',
value: documentId
}]
};
var RevisionRequestParams = {
method: action,
input_type: "JSON",
response_type: "JSON",
rest_data: DocRevObj
};
var NodeRequestParams = {
method: "set_entry",
input_type: "JSON",
response_type: "JSON",
rest_data: DocNodeObj
}
var headers = {
"Content-Type": "application/json"
};
return $http.post(endpoint, RevisionRequestParams, headers).then(
function successCallback(response2) {
console.debug("Successfully Replaced File", response2);
//Re-adjust the File Entry to match new changes
//(make a call to set_entry)
return $http.post(endpoint, NodeRequestParams, headers).then(
function successCallback(response3) {
console.debug("Successfully Updated File", response3);
return response3;
},
function errorCallback(response3) {
console.debug("Error", response3);
return response3
}
);
return response2;
},
function errorCallback(response2) {
console.debug("Error", response2);
return response2;
}
);
console.debug("Success", response);
return response;
}, function errorCallback(response) {
console.debug("Error", response);
return response;
}
);
}
参照メソッド呼び出し（コントローラ内部で、クリックイベントに発砲）
appointmentsService.appointmentsFactory.updateDocument(CurrentDocumentId, result, NewFileName, NewDocumentType, CurrentAppointmentID).then(
function successCallback(response) {
//Success Callback Logic
},
function errorCallback(response) {
});
は、それが実際には、updateDocumentの呼び出しは、約束は何かを送るずっと前にリターンを得ていることは可能ですバック？もしそうなら、それを回避する私の選択肢は何ですか？
