What I need to do is use either collection-2 or another package to automatically create a new order number, incremented from the last order number used.
i.e. Starting off with PO123456, when I save this order, the next time I make a new PO, it automatically generates the number PO123457.
I've been looking for a good example or tutorial, but I'm not able to find one.
Using konecty:mongo-counter in conjuntion with aldeed:collection2 and aldeed:simple-schema should be pretty straightforward. In your schema definition try:
POnumber: { type: String, autoValue: function(){
if ( this.isInsert ){ // restrict to when inserting a document
var currentNumber = incrementCounter('purchase order'); // this will use mongo-counter
// WARNING: you can only ever get as rich as 10M POs!!
var zeroPad = "000000" + currentNumber; // pad with 6 zeros
zeroPad = zeroPad.substr(zeroPad.length-7); // restrict to 7 places
return 'PO' + zeroPad; // prefix with 'PO'
} else if ( this.isSet ){
this.unset(); // prevent attempts to change the number
}
}

Is there any way of knowing what constraints is a body attached to? I want to create a constraint each time two bodies collide, but not each time they collide after that first constraint is already created
UPDATE: Added proof of concept
In my code, i create an array of pairs with duplicate values, and because i have a maximum of 1000 elements, each value is duplicated in x+y1000 and y+x1000 indexes so they won't overlay
// global array
var alreadyPaired = [];
// on collision check, i save which pair of values must be paired
Matter.Events.on(engine, 'collisionStart', function(event) {
var idA = event.pairs[i].bodyA.id;
var idB = event.pairs[i].bodyB.id;
if ( !alreadyPaired[idA*1000+idB] && !alreadyPaired[idB*1000+idA] ) {
alreadyPaired[idA*1000+idB] = true;
alreadyPaired[idB*1000+idA] = true;
}
});
I have a range of data in a Google Sheet and I want to store that data into an array using the app script. At the moment I can bring in the data easily enough and put it into an array with this code:
var sheetData = sheet.getSheetByName('Fruit').getRange('A1:C2').getValues()
However, this puts each row into an array. For example, [[Apple,Red,Round],[Banana,Yellow,Long]].
How can I arrange the array by columns so it would look: [[Apple,Banana],[Red,Yellow],[Round,Long]].
Thanks.
It looks like you have to transpose the array. You can create a function
function transpose(data) {
return (data[0] || []).map (function (col , colIndex) {
return data.map (function (row) {
return row[colIndex];
});
});
}
and then pass the values obtained by .getValues() to that function..
var sheetData = transpose(sheet.getSheetByName('Fruit').getRange('A1:C2').getValues())
and check the log. See if that works for you?
Use the Google Sheets API, which allows you to specify the primary dimension of the response. To do so, first you must enable the API and the advanced service
To acquire values most efficiently, use the spreadsheets.values endpoints, either get or batchGet as appropriate. You are able to supply optional arguments to both calls, and one of which controls the orientation of the response:
const wb = SpreadsheetApp.getActive();
const valService = Sheets.Spreadsheets.Values;
const asColumn2D = { majorDimension: SpreadsheetApp.Dimension.COLUMNS };
const asRow2D = { majorDimension: SpreadsheetApp.Dimension.ROWS }; // this is the default
var sheet = wb.getSheetByName("some name");
var rgPrefix = "'" + sheet.getName() + "'!";
// spreadsheetId, range string, {optional arguments}
var single = valService.get(wb.getId(), rgPrefix + "A1:C30");
var singleAsCols = valService.get(wb.getId(), rgPrefix + "A1:C30", asColumn2D);
// spreadsheetId, {other arguments}
var batchAsCols = valService.batchGet(wb.getId(), {
ranges: [
rgPrefix + "A1:C30",
rgPrefix + "J8",
...
],
majorDimension: SpreadsheetApp.Dimension.COLUMNS
});
console.log({rowResp: single, colResp: singleAsCols, batchResponse: batchAsCols});
The reply will either be a ValueRange (using get) or an object wrapping several ValueRanges (if using batchGet). You can access the data (if any was present) at the ValueRange's values property. Note that trailing blanks are omitted.
You can find more information in the Sheets API documentation, and other relevant Stack Overflow questions such as this one.
I have table with multiple customerKey values assigned to a numeric value; I wrote a script where foreach row of data I scan whole table to find all values assigned to the current customerKey and return a highest one;
I have a problem with performance - script processes around 10 records per second - any ideas how to improve this or maybe propose an alternative solution plesae?
function getLastest() {
var date = app.models.magicMain.newQuery();
var date_all = date.run();
date_all.forEach(function(e) { // for every row of date_all
var temp = date_all.filter(function(x) {
return x.SubscriberKey === e.SubscriberKey; // find matching records for the current x.SubscriberKey
});
var dates = [];
temp.forEach(function(z) { // get all matching "dates"
dates.push(z.Date);
});
var finalValue = dates.reduce(function(a, b) { // get highest dates value (integer)
return Math.max(a, b);
});
var record = app.models.TempOperatoins.newRecord(); // save results to DB
record.email = e.SubscriberKey.toString() + " " + finalValue.toString();
app.saveRecords([record]);
});
}
The only suggestion I have would be to add:
var recordstosave = [];
At the top of your function.
Then replace app.saveRecords([record]) with recordstosave.push(record).
Finally outside of your foreach function do app.saveRecords(recordstosave).
I saw major processing time improvements doing this rather than saving each record individually inside a loop.
I am trying to style just the decimals to look just like this:
Didn't had success, I guess that I need to make my own filter, tried but didn't had success either, I guess it is because I am using it inside a state.
Here the code I am using for the number:
<h2><sup>$</sup>{{salary | number:0}}<sub>.00</sub></h2>
Inside the .app iam using this scope:
$scope.salary = 9000;
Thing is, number can be whatever the user salary is, it get the number from an input, in other places I have more numbers with decimals too.
Possible solutions:
Extract only the decimals from value and print them inside de
tag.
Use a filter to do this?
Use a directive that will split the amount and generate the proper HTML. For example:
app.directive('salary', function(){
return {
restrict: 'E'
, scope: {
salary: '#'
}
, controller: controller
, controllerAs: 'dvm'
, bindToController: true
, template: '<h2><sup>$</sup>{{ dvm.dollar }}<sub>.{{ dvm.cents }}</sub></h2>'
};
function controller(){
var parts = parseFloat(this.salary).toFixed(2).split(/\./);
this.dollar = parts[0];
this.cents = parts[1];
}
});
The easiest solution would be to split out the number into it's decimal portion and the whole number portion:
var number = 90000.99111;
console.log(number % 1);
Use this in your controller, and split your scope variable into an object:
$scope.salary = {
whole: salary,
decimal: salary % 1
}
Protip: Using an object like this is better than using two scope variables for performance
In my project, I must know first and last key of child to do something. I have query same below, I use 'i' to find first but I don't know how to get last key? Have any ways to set if Firebase query complete will do function with child_added? .In test, console.log(last) but is undefinded
var i = 0;
myDataRef.limitToLast(10).on('child_added', function (snapshot){
if( i == 0)
{
first = snapshot.key;
}
renderInfo(snapshot.key, snapshot.val(), 'new');
last = snapshot.key;
});
console.log(last)
