ShopifySharp orderService.ListAsync() method doesn't return already fulfilled Orders. What is the way to get them?
var filter = new OrderListFilter() { Ids = new List { 5354837999702 } };
var shopifyOrders = service.ListAsync(filter).Result;
I was expatiating the order would show up even though its fulfilled.

I have a component that calls two functions from a service to get two lists.
I want to check how many times each element from the second list occur in the first one and append the number of occurrences in another array but for some reason whenever i do a console.log I get an empty array
Here is the Sample code to achieve your requirement. You need to create a function getFrequency which takes two arguments and returns its frequency.
let firstList = [1,2,3,4,5,6,1,2,3,4,5,6,6,2,4];
let secondList = [1,2,3,4,5,6,7];
let occurenceList = [];
let countObj ={};
function getFrequency(list,item){
return list.filter(function(value){
return value === item;
}).length
}
secondList.forEach((item)=>{
let count = getFrequency(firstList,item);
countObj = {
"item" :item,
"count" : count
};
occurenceList.push(countObj);
});
console.log(occurenceList);
I took an angularjs + firebase example and modified it for an app where I can register some kids for a small cross-country race.
I'm able to register kids (participants), races, locations, clubs etc. using a basic structure:
FIREBASE_URL/races
FIREBASE_URL/clubs
and so forth. When the active race is selected, I save the raceId and race json-object and can add participants to the active race.
Example:
FIREBASE_URL/active_race/-JI6H9VQewd444na_CQY
FIREBASE_URL/active_race/json-object
What I'd like to do is to get all the participants, if any, based on raceId:
FIREBASE_URL/races/-JI6H9VQewd444na_CQY/participants
I tried the following
'use strict';
app.factory('Race', function ($firebase, FIREBASE_URL, User) {
var ref = new Firebase(FIREBASE_URL + 'races');
var races = $firebase(ref);
var Race = {
all: races,
getParticipantsInRace: function () {
var fb = new Firebase(FIREBASE_URL);
fb.child('active_race/raceId').once('value', function (activeSnap) {
races.$child('/' + activeSnap.val() + '/participants');
});
}
};
return Race;
But I believe I'm doing it wrong. I tried to prepend return before races.$child and fb.child but it did not solve my problem.
I tried to hardcode the following json-array and this is shown on the webpage:
return [{name: 'Claus', born: '1967'}, {name: 'John', born: '1968'}];
How do I get all the participants into $scope.participantsInRace?
I believe I have a solution, but I'm not sure if it's wise to do it this way. But it may be that simple. Prepending $rootScope.participantsInRace = to put it into rootScope:
$rootScope.participantsInRace = races.$child('/' + activeSnap.val() + '/participants');
The code is already synchronizing all data in all races when it declares $firebase(URL+'races');. Additionally, you never assigned your races.$child(...) to anything, so it's not possible to reference that data later.
app.factory('Race', function ($firebase, FIREBASE_URL, User) {
var ref = new Firebase(FIREBASE_URL + 'races');
var races = $firebase(ref);
var Race = {
all: races,
getParticipantsInRace: function (raceId) {
return races[raceId]? races[raceId].participants || {};
}
};
return Race;
});
Keep in mind that the race data won't be available until races.$on('loaded') is invoked (when the data returns from the server).
Thank you for the input. I know a bit more about angularjs and javascript now so I did some refactoring and cleanup. Hardcoding raceId works:
getParticipantsInRace: function () {
return races.$child('-JIecmbdDa4kUT2L51iS').$child('participants');
}
When I wrap it in a call to Firebase I can't seem to return the desired data, probably due to my somewhat limited knowledge of javascript on how to return data. Example:
getParticipantsInRace: function () {
ref.child('activeRace').child('raceId').once('value', function (activeSnap) {
return races.$child(activeSnap.val()).$child('participants');
});
}
My idea is to get the raceId and then return all participants. I tried to prepend return to ref.child() but still no data was returned. So not really an answer.

This works. I changed $rootScope.participantsInRace to $scope.participantsInRace and the following:
getParticipantsInRace: function () {
if (User.signedIn()) {
var t = [];
var user = User.getCurrent();
var fb = new Firebase(FIREBASE_URL + 'users');
fb.child(user.username).child('activeRace/raceId').once('value', function (userSnap) {
t = races.$child(userSnap.val()).$child('participants');
});
return t;
}
},
[{"time":136803,"price":"1.4545","amount":"0.0885","ID":"112969"},
{"time":136804,"price":"2.5448","amount":"0.0568","ID":"5468489"},
{"time":136805,"price":"1.8948","amount":"0.0478","ID":"898489"}]
I have a large JSON file like the one above. It is a list of dictionaries. I want to choose a time and find the value assoaciated with that time. I will not know where in my list the time is located only the value for the time. Is there a way I can say, for time 136804, make x = to price? Or should I loop through each value? I also want to use this value (x) in a mathematical function.
My fist idea is to use brute force by going through each item and checking it for a matching time value in a loop.
Is this the best way?
Take a look at SpahQL http://danski.github.io/spahql/ which we use to query JSON in order to select values and subsequently change them as required.
I did something similar to this recently. JSON file I had to query had around 6000 lines and around 500 JSON objects. My query function given below loops through the each object to select the matching objects, but it can fetch any result within few milliseconds.
var data = '[{"time":136803,"price":"1.4545","amount":"0.0885","ID":"112969"},'+ '{"time":136804,"price":"2.5448","amount":"0.0568","ID":"5468489"},'+ '{"time":136805,"price":"1.8948","amount":"0.0478","ID":"898489"}]';
var data = JSON.parse(data);
var query = function(data, select, andwhere) {
var return_array = [];
$.each(data, function (i, obj) {
var temp_obj = {};
var where = true;
if (andwhere) {
$.each(andwhere, function(j, wh) {
if (obj[wh.col] !== wh.val) {
where = false;
}
});
}
if (where === false) {
return;
}
$.each(obj, function (j, elem) {
if (select.indexOf(j.trim())!==-1) {
temp_obj[j] = elem;
}
});
return_array.push(temp_obj);
});
return return_array;
};
var result = query(data, ['price','amount'],[{"col":"time","val":136804}]);
console.log(JSON.stringify(result));

I want to write a function in JS where I will loop through a tables in my indexed DB and get the maximum value of last modified of table and return that
function readData(){
var trans = '';
trans = idb.transaction(["tableName"],'readonly'); // Create the transaction
var request = trans.objectStore("tableName").openCursor();
request.onsuccess = function(e) {
var cursor = request.result || e.result;
if(cursor) {
// logic to and find maximum
} else {
return // max last modified
}
cursor.continue();
}
}
IMP--Since onsuccess method is asynchronous how can i make it synchronous? so that my method readData() will return only when max last modified record is found successfully. I can call this method(readData()) synchronously to get last modified record of 2-3 tables if I want.
The sync API is only available in a webworker. So this would be the first requirement. (As far as I know only IE10 supports this at the moment)
An other shot you can give is working with JS 1.7 and use the yield keyword. For more information about it look here
I would sugest to work with a callbakck method that you call when you reached the latest value.
function readData(callback){
var trans = '';
trans = idb.transaction(["tableName"],'readonly'); //Create the transaction
var request = trans.objectStore("tableName").openCursor();
var maxKey;
request.onsuccess = function(e) {
var cursor = request.result || e.result;
if(cursor.value){
//logic to and find maximum
maxKey = cursor.primaryKey
cursor.continue();
}
}
trans.oncomplete = function(e) {
callback(maxKey);
}
}
IndexedDB API in top frame is async. async cannot be synchronous. But you can read all tables in single transaction.
Given:
using (DataContext ctx = new DataContext(props.ConnectionString))
{
IQueryable<Email> emails = null;
try
{
emails = ctx.Emails.Where(e => !(e.IsLocked || e.IsSent));
foreach (var e in emails)
{
e.IsLocked = true;
}
ctx.SubmitChanges();
}
}
// do something with emails here
Why is emails empty after SubmitChanges()? Is there any way to avoid emptying the Table after IsLocked is set to true?
The table ctx.Emails is probably not empty. The collection emails is evaluated every time you call it.
You could do this if you want to keep the emails return on the initial call:
emails = ctx.Emails.Where(e => !(e.IsLocked || e.IsSent)).ToList().AsQueryable();
Thomas's answer is correct but I'll have a go at explaining it as well.
The emails collection is an enumeration that is reevaluated when you call it. Picture it like this.
// another method...
IEnumerable<Email> GetEmails()
{
return ctx.Emails.Where(e => !(e.IsLocked || e.IsSent));
}
// & inside your main method
foreach (var e in GetEmails())
{
e.IsLocked = true;
}
ctx.SubmitChanges();
// now if you check the result it will be reevaluated
GetEmails();
This is intended behaviour.
If you want to 'get' the emails, do something to them and keep that collection, you should put them in a list / array. The enumeration isn't a real collection, it's more like a function that returns a collection when you query it.
