I am having query like below
var db = admin.database();
var ref = db.ref('orders') ref.orderByChild("order/_date").startAt(begDate).endAt(endDate).once("value").then(
(resp) => {
..
}).catch(
(err) => console.log('failed in sales report:' + err)
)
it throws below
TypeError: Cannot convert undefined or null to object
The data looks like below
orders: {
"-LNMPXMb1SGSnkDaEMQO" : {
"order" : {
"_cgst" : "11.90",
"_date" : "1538368446413",
"_location" : "kapashera",
"_orderNumber" : "VikKumar-21247",
"_orderStatus" : "Delivered",
}
},
At the time of execution the begDate and endDate are:
begDate:1538352000000 endDate:1538438400000
So two problems:
1.The error itself. How can I avoid throwing error if no match?
2. Why is the above record not matching when the date value is between begDate and endDate?
You are probably doing the same error than in you other question of yesterday: firebase realtime DB querying date between 2 dates does not match anything
Therefore, the reason is probably because begDate and endDate are numbers but you store _date as a string in your database.
Try using toISOString when you save to fb
var _date = new Date().toISOString()
and
var d = new Date();
var year = d.getFullYear();
var month = d.getMonth();
var day = d.getDate();
var begDate = new Date(year - 1, month, day).toISOString();
var endDate = new Date(year + 1, month, day).toISOString();

I have a function here that gets the date, and adds one week to it:
func thingy() {
let currentDate = Date()
var dateComponent = DateComponents()
dateComponent.day = 7
let futureDate = Calendar.current.date(byAdding: (dateComponent*i), to: currentDate)
print(futureDate!.formatted())
}
This gets the current date, adds one week to it, and prints out that date.
I want to get a for loop that will give the date, for example maybe 10 weeks in the future, maybe looking something like this:
for i in 1...num[ex: 11] {
let currentDate = Date()
var dateComponent = DateComponents()
dateComponent.day = 7
let futureDate = Calendar.current.date(byAdding: (dateComponent*i), to: currentDate)
let match = (title: "Test", date: futureDate)
}
I get this error:
Referencing operator function '*' on 'DurationProtocol' requires that 'DateComponents' conform to 'DurationProtocol'
How do I fix this?
I would advise adding .weekOfYear to the date. E.g., to get an array of Date representing the next ten weeks:
let calendar = Calendar.current
let today = calendar.startOfDay(for: Date())
let dates = (1 ... 10)
.compactMap { calendar.date(byAdding: .weekOfYear, value: $0, to: today) }
I have copied the data from Googlesheet1 to Googlesheet2 using the below query
=IMPORTRANGE("url","!A2:H")
Which has copied the data from Googlesheet1 to Googlesheet2.
In that sheet, I am having a duration column like the below image
When i used the app script to copy the data to the firestore instead of saving the duration it saves the data in DateTime format like below.
Is there any way to convert the given duration to seconds in Google sheet.
I have tried using =value(G2*24*3600) but it didn't work in the Googlesheet2 since that sheet is a clone of Googlesheet1
App script Logic:
function firestore() {
// Firestore setup
const email = "//client-email";
const key = "//client-key";
const projectId = "timesheet-aog";
var firestore = FirestoreApp.getFirestore (email, key, projectId);
// get document data from ther spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetname = "timesheet";
var sheet = ss.getSheetByName(sheetname);
// get the last row and column in order to define range
var sheetLR = sheet.getLastRow(); // get the last row
var sheetLC = sheet.getLastColumn(); // get the last column
var dataSR = 2; // the first row of data
// define the data range
var sourceRange = sheet.getRange(2,1,sheetLR-dataSR+1,sheetLC);
// get the data
var sourceData = sourceRange.getValues();
// get the number of length of the object in order to establish a loop value
var sourceLen = sourceData.length;
console.log('sourceLen is', sourceLen);
// Loop through the rows
for (var i=0;i<sourceLen;i++){
var data = {};
console.log('data is', sourceData);
data.date = sourceData[i][0];
data.name = sourceData[i][1];
data.workFrom = sourceData[i][2];
data.project = sourceData[i][3];
data.phase = sourceData[i][4];
data.task = sourceData[i][5];
data.totalHrs = sourceData[i][6];
data.comments = sourceData[i][7];
firestore.createDocument("timesheet",data);
}
}
Here is the formula for A1 cell of the second sheet:
={
IMPORTRANGE("url","!A2:F"),
ARRAYFORMULA(
IF(
IMPORTRANGE("url","!G2:G") = "",
"",
N(IMPORTRANGE("url","!G2:G")) * 24 * 3600
)
),
IMPORTRANGE("url","!H2:H")
}
Try using named ranges for columns (A2:F, G2:G, H2:H) in the original sheet, and import them by those names so you won't need to adjust the formula where exact column names are used.
Hi Need some help with LINQ query.
I have entity called Shift. This entity has several value field but the ones I am intressted in are ShiftID (int), ShiftDate (DateTime) and GrossMount (decimal(10,2). And this needs to be grouped by month (binding this to a graph in ASP.NET).
I need data for the last 12 months grouped by month.
I have come a bit on the way with this post: Linq to Entity, selecting group without value but not quite all the way.
This is my code for now:
public IQueryable<Shift> GetPastMonths(int months, string accountNumber)
{
_context = new EtaxiEnteties();
var _date = DateTime.Today;
var _firstOfMonth = new DateTime(_date.Year, _date.Month, 31);
var _twelveMonthAgoFirstOfMonth = _firstOfMonth.AddMonths(-12);
// Generate a collection of the months and years for the last 12 months
var _monthYears = Enumerable.Range(-12, 12).Select(monthOffset => { var monthDate = _firstOfMonth.AddMonths(monthOffset); return new { y = monthDate.Year, m = monthDate.Month }; });
var _data = (from _monthYear in _monthYears
join _i in
(from _i in _context.Shifts.Where(acc => acc.Account.AccountNumber == accountNumber)
where _i.ShiftDate >= _twelveMonthAgoFirstOfMonth && _i.ShiftDate < _firstOfMonth
group _i by new { y = _i.ShiftDate.Year, m = _i.ShiftDate.Month } into g
select new { ShiftID = g.Key, GrossAmount = g.Count() }) on _monthYear equals _i.ShiftID into j
from _k in j.DefaultIfEmpty()
select new Shift() { ShiftDate = new DateTime(_monthYear.y, _monthYear.m, 1), GrossAmount = _k != null ? _k.GrossAmount : 0 });
return _data as IQueryable<Shift>;
}
Now I have in return a collection of Shift objects, grouped by month but still missing the GrossAmount. Althoug i would need this from today date (only getting from 1 of current month).
Believe this is my main problem: GrossAmount = g.Count(), but I am not sure
Any LINQ specialist out there that could give me a push?
Use GrossAmount = g.Sum(x => x.GrossAmount) to calculate total GrossAmount value of grouped Shift entities. I believe you have typo in GrossAmount (GrossMount) property name.
I having a trouble with a query
I need to take out the SHIPMENT from GetAllOrderData - the same place where you can find POD_DATE and RECEIVE_NAME...but I get an error
Error 1 The name 'x' does not exist in the current context
My code is:
public IEnumerable<ReportItemDTO> GetTaskProgress(DateTime targetDate)
{
try
{
var startDate = targetDate.Date;
var endDate = startDate.AddDays(1);
OrderDataRepository rep = new OrderDataRepository();
var query = rep.GetAllOrderData()
.Where(x => x.POD_DATE >= startDate && x.POD_DATE <= endDate)
.GroupBy(o => o.User)
.Select(g => new ReportItemDTO
{
DriverId = g.Key.Id,
PdriverName = g.Key.Name,
OrderCount = g.Count(),
ReportedOrdersCount = g.Count(o => o.RECEIVE_NAME != null),
SHIPMENT = (x.SHIPMENT)
} );
return query;
SHIPMENT = (x.SHIPMENT)
Well you are within a grouping when you try to make that assignment - there are many shipments in each grouping not just one - in fact all shipments for that particular user. Assuming you want a collection of them you could do:
Shipments = g.Select( x=> x.SHIPMENT)
Edit:
If you just want the first shipment for each user (somewhat illogical but fits your data model):
SHIPMENT = g.Select( x=> x.SHIPMENT).First()
I have the following:
var currentDate = DateTime.UtcNow;
var calendarEntry = from item in new CalendarEntryRepository(this.Db).List().Where(x => x.Culture == language.Value)
group item by item.ContentObjectId into g
let itemMaxDate = g.Where(i => i.StartDate > currentDate).Select(i => i.StartDate).DefaultIfEmpty()
let city = g.Select(i => i.City).FirstOrDefault()
select new
{
ContentObjectId = g.Key,
StartDate = itemMaxDate,
City = city ?? string.Empty
};
From CalendarEntryRepository I want to group by ContentObjectId (this works fine). However when i add this line:
let itemMaxDate = g.Where(i => i.StartDate > currentDate).Select(i => i.StartDate).DefaultIfEmpty()
I keep getting this error:
Message = "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value."
What i'm trying to do is group by ContentObjectId and then get StartDate that is greater than today.
I'm using entity framwork and MS SQL2008
thanks
The Min Value of DateTime in your database has a lower value that the MinValue defined int he culture you used in your App.
Change the StartDate column in DataBase to data type DateTime2 to support a broader range of dates
