Problem: the computed property "tnop" does not get updated when the controller modifies the "pages" array as shown below:
relevant book model code:
sections: []
tnop: function()
{
var n = 0;
var sections = this.get('sections');
if (!sections)
return n;
for (var i=0; i < sections.length; i++) {
n += sections[i].pages.length;
}
return n;
}.property('sections.#each.pages.length')
relevant controller code:
var sections = EM.model.getPath('book.sections');
var aps = EM.model.getPath("ps");
$.each(sections, function(si, section) {
var bp = [];
if (json && json.ia) {
bp = section.get("pages");
var ns = aps[json.ssi];
var lp = ns.get("lp");
var rp = ns.get("rp");
if (rp) {
bp.insertAt(lp.number-1, rp);
bp[lp.number-1] = rp;
}
if (lp) {
bp.insertAt(lp.number-1, lp);
bp[lp.number-1] = lp;
}
}
});
As it stands, you can't observe deeply nested paths off #each directly. Instead, you have to use nested #each proxies, as such:
property('sections.#each.pages.#each.length')
Had the same problem solved using with following code:
filters: [],
content: [],
filterFun: function()
{
}.property('content.#each', 'filters.#each').cacheable(),

I have been trying many ways to add an isChecked: false attribute to every list inside the _filterOptions List in my Flutter Project. I couldn't find any solution to this. If there is any solution I am happy to see it.
List<dynamic> _filters = [];
List<List<dynamic>> _filterOptions =[];
var filters =
await json.decode(data)["getProductsByStore"]["aggregations"];
for(int i = 0; i < filters.length; i++){
_filters.add(filters[i]["label"]);
_filterOptions.add(filters[i]["options"]);
}
//print(filters[0]["options"]);
//print(_filters);
print(_filterOptions);
I am getting this kind of nested list when printed and I want to add the attribute to every list.
as an example:
[[{count: 3, label: 30-40, value: 30_40, isChecked:false}], [{count: 2, label: Bagged , value: 50, isChecked:false},{...},{...}...]]
Create Model class with your data and bool isChecked
class ModelClass{
String? label;
int? count;
List? options;
bool? isChecked;
ModelClass({this.label, this.count , this.options, this.isChecked = false});
ModelClass.fromJson(Map<String, dynamic> json){
label = json['label'];
count = json['count'];
options = json['options'];
}
}
then you can add data like below code
List<ModelClass> list = [];
void function()async{
List<dynamic> _filters = [];
List<List<dynamic>?> _filterOptions =[];
var filters =
await json.decode(data)["getProductsByStore"]["aggregations"];
for(int i = 0; i < filters.length; i++){
ModelClass modelClass = ModelClass.fromJson(filters[i]);
list.add(modelClass);
_filters.add(modelClass.label);
_filterOptions.add(modelClass.options);
}
print(list[0].options);
print(list[0].isChecked);
}
if you want to modify isChecked for some specific index
list[0].isChecked = false;
Just add these lines.
class YourWrapperClass {
YourWrapperClass({this.filterOptions = const [], this.isChecked = false});
List<List<dynamic>> filterOptions;
bool isChecked;
}
YourWrapperClass filterWrapper = YourWrapperClass(filterOptions: _filterOptions, isChecked: false);
And use this wrapper class object whenever ya need to access _filterOptions.
But, I would more rather recommend using the WrapperClass on the list elements, like so.
class YourWrapperClass {
YourWrapperClass({this.filterOption = const [], this.filter="", this.isChecked = false});
List<dynamic> filterOption;
dynamic filter;
bool isChecked;
}
List<YourWrapperClass> list = [];
var filters =
await json.decode(data)["getProductsByStore"]["aggregations"];
for(int i = 0; i < filters.length; i++){
list.add(YourWrapperClass(filterOption:filters[i]["options"], filter:filters[i]["label"], isChecked=false));
_filterOptions.add(filters[i]["options"]);
}
I always have reduce issue on practicing, like following map and reduce, if I add more document or add more field to emit in the map and reduce like following. it will return values as [], not sure what occur this?
problemNumber : doc.problemNumber,
UserId: idv,
event : doc.event
......
Map
function(doc) {
if(doc.event){
var idv = null;
for (var idu in doc.Data.users){
if (doc.eventData.users[idu].userTypeCode == "M"){
idv = doc.Data.users[idu].UserId;
}
}
var newDoc = {
problemNumber : doc.problemNumber,
UserId: idv,
event : doc.event
};
emit(null, newDoc);
}
}
Reduce
function(keys, values, rereduce) {
var result = [];
var closeMap = {};
for (var i=0; i<values.length; i++){
var doc = values[i];
if (doc.event=='CLOSE'){
closeMap[doc.problemNumber] = 1;
}
}
for (var i=0; i<values.length; i++){
var doc = values[i];
if (doc.event=='OPEN'){
if (closeMap[doc.problemNumber]){
doc.event = 'CLOSE';
}
result.push(doc);
}
}
return result;
}
I have an email sent out on a daily basis that I need to pull data from to a Google Sheet. I have read on this and found a solution that worked for other's, but I've been unable to get it to work on mine. This is the code I've tried modifying:
function menu(e) {
var ui = SpreadsheetApp.getUi();
ui.createMenu('Macros')
.addItem('parse mail', 'email')
.addToUi();
}
function parseMail(body) {
var a=[];
var keystr="First Name : ,Last Name : ,Customer ID : ,Invoice : ";
var keys=keystr.split(",");
var i,p,r;
for (i in keys) {
p=keys[i]+"\n([a-zA-Z0-9\ \,\.]*)\n";
r=new RegExp(p,"m");
try {a[i]=body.match(p)[1];}
catch (err) {a[i]="no match";}
}
}
function email() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getActiveSheet();
var threads = GmailApp.search('subject: "Fwd: ARB Subscription*"');
var a=[];
for (var i = 0; i < threads.length; i++) {
var messages = GmailApp.getMessagesForThread(threads[i]);
for (var j = 0; j < messages.length; j++) {
a[j]=parseMail(messages[j].getPlainBody());
}
}
var nextRow=s.getDataRange().getLastRow()+1;
var numRows=a.length;
var numCols=a.length[0];
s.getRange(nextRow,1,numRows,numCols).setValues(a);
}
I've tried modifying the code, but the error I am getting is Cannot convert Array to Object[][] Line 35. any advice would be greatly appreciated
Get the dimensions of the data range as below.
Also, when you are setting the values on the range the size of two-dimensional array a must match the size of the range.
var dataRange = s.getDataRange();
var nextRow = dataRange.getLastRow() + 1;
var numRows = dataRange.getNumRows();
var numCols = dataRange.getNumColumns();
s.getRange(nextRow,1,numRows,numCols).setValues(a);
I am trying to extract an ID from my URL and paste it in the sharepoint List into the ID text box, I have tried it like that:
<script type=”text/javascript”>
function GetQueryStringParams(sParam)
{
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++)
{
var sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] == sParam)
{
return sParameterName[1];
}
}
}
document.forms['aspnetForm'].ctl00_m_g_d9f5e4f9_7e05_4a4d_88b7_a6b1dcdda667_ctl00_ctl01_ctl00_ctl00_ctl00_ctl04_ctl00_ctl00_TextField.value=GetQueryStringParams(‘ID’);
</script>
however it does not work, my URL:
http://Lists/Systems%20Survey/NewForm.aspx?Source=http://Lists/Systems%2520Survey/overview.aspx&ID=14-01234
I have put it as a web part xml on my web.
Do you have any idea what I did wrong? :)
thanks for assistance
Use the function below as getQueryVariable('source')
function getQueryVariable(variable) {
var query = window.location.search.substring(1);
var vars = query.split('&');
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split('=');
if (decodeURIComponent(pair[0]) == variable) {
return decodeURIComponent(pair[1]);
}
}
console.log('Query variable %s not found', variable);
}
Is it possible to use underscore's groupBy function with ember.js?
I have the following attempt which is obviously not working:
var activities = App.store.findMany(App.Activity, feed.mapProperty('id').uniq())
var grouped = _.groupBy(activities, function(activity){
return activity.get('dateLabel;')
});
I get the following error:
Object App.Activity has no method 'get'
The store is loaded with the correct data so findMany will not make a remote call.
The problem is that findMany returns a DS.ManyArray which is probably a lot different than what _.groupBy is looking for.
You could implement your own groupBy function tailored for ember-data DS-ManyArray objects and extend _ with it:
_.emberArrayGroupBy = function(emberArray, val) {
var result = {}, key, value, i, l = emberArray.get('length'),
iterator = _.isFunction(val) ? val : function(obj) { return obj.get(val); };
for (i = 0; i < l; i++) {
value = emberArray.objectAt(i);
key = iterator(value, i);
(result[key] || (result[key] = [])).push(value);
}
return result;
};
Now you can call
var grouped = _.emberArrayGroupBy(activities, function(activity) {
return activity.get('dateLabel');
});
or more simply
var grouped = _.emberArrayGroupBy(activities, 'dateLabel');
The function above is based on underscore's original groupBy() implementation, which looks very similar:
_.groupBy = function(obj, val) {
var result = {};
var iterator = _.isFunction(val) ? val : function(obj) { return obj[val]; };
each(obj, function(value, index) {
var key = iterator(value, index);
(result[key] || (result[key] = [])).push(value);
});
return result;
};
Try this code:
var activities = App.store.findMany(App.Activity, feed.mapProperty('id').uniq())
var grouped = _.groupBy(activities, function(activity){
return activity.get('dateLabel;')
}).bind(this);
I did not run this code to test how it works but the idea is to 'bind' outer scope into inner closure function scope.
Hope this helps to get you some ideas...
