I need your opinion in this situation:
I get from API with this function:
getRS(
idProject: string
): Observable<ResponseModel<RSModel>> {
return this.http.get<ResponseModel<RSModel>>(
ApiUrlsConfig.getRS(
idProject
)
);
}
this response:
{
"data": [
{
"id": "id1",
"state": 1,
"note": null
},
{
"id": "id1",
"state": 2,
"note": "Reason 1"
},
{
"id": "id2",
"state": 2,
"note": "Reason updated3",
}
],
"result": null
}
I need to use filter in this response because I should be get the last state for each id. For example, I want to display state 2 in item with id: id1. For this I want to use filter. The problem is because I can't use filter on it, I don't understand why.
I tried to write this code:
#Input() set jobId(jobId: string) {
this.optionsService
.getRS(
this.idProject
)
.pipe()
.subscribe((res) => {
let resId = res.filter((aaa)=>{
if(aaa.id === jobId){
res.slice(-1)[0].id
}
}
)
});
}
Not function.
Please can you share with me any idea?
Thank you
Try this logic:
Loop backwards throw it.
Loop backwards over index to the start.
Splice duplicates.
let response = {
"data": [
{
"id": "id1",
"state": 1,
"note": null
},
{
"id": "id1",
"state": 2,
"note": "Reason 1"
},
{
"id": "id2",
"state": 2,
"note": "Reason updated3"
}
],
"result": null
}
let data = response.data;
for (let i = data.length - 1; i >= 0; i--) {
for (let j = i - 1; j >= 0; j--) {
if (data[i].id === data[j].id) {
data.splice(j, 1);
j++;
}
}
};
console.log(data);
try this:
if(aaa.id == jobId){
return res.slice(-1)[0].id
}

sample json data is this:
{
"variations": [
{
"variation_id": 391,
"name": "Fruit Shake - Chocolate, S",
"price": 10,
"attribute": [
{
"attribute_key": "pa_flavor",
"name": "Flavor",
"option": "Chocolate"
},
{
"attribute_key": "pa_size",
"name": "Size",
"option": "S"
}
]
},
{
"variation_id": 385,
"name": "Fruit Shake - Banana, L",
"price": 18,
"attribute": [
{
"attribute_key": "pa_flavor",
"name": "Flavor",
"option": "Banana"
},
{
"attribute_key": "pa_size",
"name": "Size",
"option": "L"
}
]
},
{
"variation_id": 386,
"name": "Fruit Shake - Banana, M",
"price": 15,
"attribute": [
{
"attribute_key": "pa_flavor",
"name": "Flavor",
"option": "Banana"
},
{
"attribute_key": "pa_size",
"name": "Size",
"option": "M"
}
]
}
]
}
my problem is, getting the variation_id where 2 or more attributes matches the array of string.
for example, chosenProduct = ["Banana", "L"]
I tried filter and contains but theres no way to match the other item from chosenProduct.
If I added the next condition, it returns nil
You can try this:
let varID = product.variations?.filter { att in
var matchedAttributes = 0
for thisAttribute in att.attribute {
if chosenProduct.contains(where: {$0 == thisAttribute.option}) {
matchedAttributes += 1
}
}
if matchedAttributes >= 2 {
return true
}
return false
}
Let me know if there's any doubt.
You can try this :
var chosenProduct = ["Banana","L"]
var expectedIds : [Int] = [Int]()
datas.variations?.map{ val in
val.attribute.map({ val2 in
let filtered = val2.enumerated().filter({chosenProduct.contains($0.element.option!)})
if filtered.count == chosenProduct.count{
expectedIds.append(val.variation_id!)
}
})
}
print(expectedIds) // [385]
I put the id's in array because of if you want to change your chosenProcudt example "Banana" (count 1 ). This mapping must be return variation_id like [385,386]
You can a method to Variation to make things easier:
extension Variation {
func attributesMatching(options: [String]) -> [Attribute] {
attribute.filter { options.contains($0.option) }
}
}
Then, you can just write:
let filtered = product.variations.filter { $0.attributesMatching(options: chosenProductOptions).count >= 2 }
print(filtered.map { $0.variationID })

Hello all,
i'm having this unexpected behaviour when trying to update a document with multiple pull request based on matching criterias. here is what i mean
my document schma looks like this
{
"_id": "5a1c0c37d1c8b6323860dfd0",
"ID": "1511781786844",
"main": {
"_id": "5a3c37bfc065e86a5c593967",
"plan": [
{
"field1": 1,
"field2": 1,
"_id": "5a3c30dfa479bb4b5887e56e",
"child": []
},
{
"field1": 1,
"field2": 2,
"_id": "5a3c30e1a479bb4b5887e5c",
"child": []
},
{
"field1": 1,
"field2": 3,
"_id": "5a3c37bfc065e86a5c593968",
"child": []
},
{
"field1": 1,
"field2": 4,
"_id": "5a3c37bfc065e86a5c593655",
"child": []
},
{
"field1": 1,
"field2": 5,
"_id": "5a3c30dfa479bb4b5887e56f",
"child": []
},
{
"field1": 1,
"field2": 6,
"_id": "5a3c30e1a479bb4b6887e545",
"child": []
},
{
"field1": 1,
"field2": 7,
"_id": "5a3c37bfc065e86a5c5939658",
"child": []
},
{
"field1": 2,
"field2": 2,
"_id": "5a3c37bfc065e86a5c593963",
"child": []
},
]
},
...
....
}
and this is my code to update the document:
Schema.findOne({ID: data.ID})
.then(function(doc) {
var array = doc.main.plan;
for (i = 0; i < array.length; i++) {
if ( array[i].field1=== 1 )) {
var id = array[i]._id;
console.log('pulling');
doc.pull( { _id: id });
}
}
doc.save().then(function(doc) {
console.log('saving');
// console.log(doc);
if (doc && doc.docID) {
return { success: true };
} else {
return { success: false, error: 'unknownError'}
}
})
}
now the issue is let's say my array has 7 objects that matches the test (array[i].theField === parseInt(updFields.theField)), when i run this and check the logs i see that it will basically pull half of the objects and do a save.
so i would get
pulling
pulling
pulling
pulling
save.
and then i have to run the code for the remaining 3 objects in the array and get
pulling
pulling
saving
so i have to run it a third time to completely clear the array.
need help get this working
thank you
So i created a little workaround by doing a recursive function to pull all with only one click using lodash functions. not pretty but it does the job.
const delObjArray = (doc, cond) => {
const checkField = cond.field;
const checkVal = cond.value;
_.forEach(doc, (value) => {
if (value && value[checkField] === checkVal) {
doc.pull({ _id: value._id });
}
});
const isFound = _.some(doc, { [checkField]: checkVal });
if (isFound) {
delObjArray(doc, cond);
} else {
return true;
}
return true;
};
Hi can somebody help Removing element from nested json array like this
JSON
[{
"id": 1,
"name": "Furniture & Fixture",
"choice": {
"0": {
"req_goods": "table",
"qty": "10"
},
"1": {
"req_goods": "chair",
"qty": "5"
}
}
}, {
"id": 2,
"name": "Miscellaneous Property",
"choice": {
"0": {
"req_goods": "Office Rent",
"qty": "1"
}
}
}]
here how do I remove choice 1 of id 1 .
HTML
<div ng-repeat="cb in capital_budgets">
<div ng-repeat="choice in choices[$index]">
<input ng-model="cb.choice[$index].req_goods">
<input ng-model="cb.choice[$index].qty">
<button ng-hide="$first" ng-click="removeChoice($parent.$index,$index)">-</button>
</div>
<button ng-click="addNewChoice($index)">+</button>
</div>
JS
$scope.capital_budgets = [{"id":1,"name":"Furniture & Fixture"},
{"id":2,"name":"Miscellaneous Property"}];
$scope.choices = [{}];
$scope.choices[0] = [{}];
$scope.choices[1] = [{}];
$scope.choices[2] = [{}];
$scope.choices[3] = [{}];
$scope.choices[4] = [{}];
$scope.addNewChoice = function(id) {
$scope.choices[id].push({});
};
$scope.removeChoice = function(parent_id, id) {
$scope.choices[parent_id].splice(id, 1);
};
The Above removeChoice() remove last element but I want to remove the element that user choose to remove. please help i have been trying from 2 days.
You can make 'choice' of the array type as follows and use the index of the particular choice in the ng-repeat directive to remove the choice from the choices array.
angular
.module('demo', [])
.controller('DefaultController', DefaultController);
function DefaultController() {
var vm = this;
vm.items = [
{
"id": 1,
"name": "Furniture & Fixture",
"choices": [
{
"id": 1,
"req_goods": "table",
"qty": "10"
},
{
"id": 2,
"req_goods": "chair",
"qty": "5"
}]
}, {
"id": 2,
"name": "Miscellaneous Property",
"choices": [
{
"id": 1,
"req_goods": "Office Rent",
"qty": "1"
}]
}];
vm.removeChoice = removeChoice;
vm.addChoice = addChoice;
function removeChoice(itemId, index) {
for (var i = 0; i < vm.items.length; i++) {
if (vm.items[i].id === itemId) {
vm.items[i].choices.splice(index, 1);
break;
}
}
}
function addChoice(index) {
var id = vm.items[index].choices.length + 1;
vm.items[index].choices.push({
id: id,
req_goods: "",
qty: 0
});
}
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="demo">
<div ng-controller="DefaultController as ctrl">
<div ng-repeat="item in ctrl.items">
<h3>{{item.name}}</h3>
<div ng-repeat="choice in item.choices">
<input type="text" ng-model="choice.req_goods" />
<input type="text" ng-model="choice.qty" />
<button type="button" ng-click="ctrl.removeChoice(item.id, $index)">Remove</button>
</div>
<button type="button" ng-click="ctrl.addChoice($index)">Add</button>
</div>
</div>
</div>
You can remove choice "1" of id 1 using the below code snippet.
var json = [
{
"id": 1,
"name": "Furniture & Fixture",
"choice": {
"0": {
"req_goods": "table",
"qty": "10"
},
"1": {
"req_goods": "chair",
"qty": "5"
}
}
}, {
"id": 2,
"name": "Miscellaneous Property",
"choice": {
"0": {
"req_goods": "Office Rent",
"qty": "1"
}
}
}];
function removeChoice(json, parentId, choice) {
for (var i = 0; i < json.length; i++) {
if (json[i].id === parentId) {
delete json[i].choice[choice];
break;
}
}
}
removeChoice(json, 1, "1");
console.log(json);
If you want the the choice also to be of the same type as its parent element i.e. an array you could change your JSON as follows and do as shown in the below code snippet to remove a choice from the JSON
var json = [
{
"id": 1,
"name": "Furniture & Fixture",
"choices": [
{
"id": 1,
"req_goods": "table",
"qty": "10"
},
{
"id": 2,
"req_goods": "chair",
"qty": "5"
}]
}, {
"id": 2,
"name": "Miscellaneous Property",
"choices": [
{
"id": 1,
"req_goods": "Office Rent",
"qty": "1"
}]
}];
function removeChoice(json, parentId, choiceId) {
for (var i = 0; i < json.length; i++) {
if (json[i].id === parentId) {
for (var j = 0; j < json[i].choices.length; j++) {
if (json[i].choices[j].id === choiceId) {
json[i].choices.splice(j, 1);
break;
}
}
break;
}
}
}
removeChoice(json, 1, 1);
console.log(json);
In both of the above methods I've passed the source you want to modify as a parameter to the removeChoice function whereas you can also directly use a variable available within the scope of execution of the removeChoice function and pass only parentId and choiceId as parameters in the below code snippet, you can replace items with the object on your controller's $scope.If you prefer isolation of the code you can pass the items object as a parameter to the removeChoice function as it won't be dependent on the external components directly being used in the method body, I would suggest to have separation of concerns.
var items = [
{
"id": 1,
"name": "Furniture & Fixture",
"choices": [
{
"id": 1,
"req_goods": "table",
"qty": "10"
},
{
"id": 2,
"req_goods": "chair",
"qty": "5"
}]
}, {
"id": 2,
"name": "Miscellaneous Property",
"choices": [
{
"id": 1,
"req_goods": "Office Rent",
"qty": "1"
}]
}];
function removeChoice(parentId, choiceId) {
for (var i = 0; i < items.length; i++) {
if (items[i].id === parentId) {
for (var j = 0; j < items[i].choices.length; j++) {
if (items[i].choices[j].id === choiceId) {
items[i].choices.splice(j, 1);
break;
}
}
break;
}
}
}
removeChoice(1, 1);
console.log(items);
Try This
$scope.removeChoice = function(parent_id,id) {
var TempArr=[];
var parentLength=$scope.choices[parent_id].length;
for(i=0;i<parentLength;i++ ){
if(parentLength[i]!==id){
TempArr.push(parentLength[i]);
}
if(i==parentLength-1){
$scope.choices[parent_id]=[];
$scope.choices[parent_id]=TempArr;
}
}
};

I have changed my JSON, then I can't able to filter the data.
var result = $filter('filter')(foo.results, {id:2426})[0];
if you limit on your JSON data
and you can make sure the data property value is num
maybe you can try this ...
var foo = {
"count": 70,
"language": "en",
"0": {
"id": "2420",
"name": "Medical Center"
},
"1": {
"id": "7840",
"name": "Conference Room"
},
"2": {
"id": "2426",
"name": "Deck 5 Starboard"
}
};
foo.results = [];
for(var property in foo){
if(property == parseInt(property, 10).toString()){
foo.results.push(foo[property]);
}
}
var result = $filter('filter')(foo.results, {id:2426})[0];
$scope.name = result.name;
wish help !!
How I can create a $filter with custom function to determining if match ?
This is a json sample with structure:
$scope.routes =[
{
"id": 0,
"name": "Rosa Barnes",
"origin": [
{
"address": [
{
"locality": "Madrid",
"country": "ES"
}
]
}
]
},
{
"id": 1,
"name": "Wright Montoya",
"origin": [
{
"address": [
{
"locality": "London",
"country": "UK"
}
]
}
]
},
{
"id": 2,
"name": "Pearson Johns",
"origin": [
{
"address": [
{
"locality": "London",
"country": "UK"
}
]
}
]
}
];
I want a $filter that passing one country, match in origin.address.country , is possible?
I proved this code but not works:
$scope.routesToShow = $filter('filter')($scope.routes, {origin.address.country: "UK"});
Here there are a demo:
http://jsfiddle.net/86U29/43/
Thanks
What you need is a custom filter. It also looks like you might need to tweak your data structure too.
Take a look at this:
app.filter('CustomFilter', function () {
function parseString(propertyString) {
return propertyString.split(".");
}
function getValue(element, propertyArray) {
var value = element;
propertyArray.forEach(function (property) {
value = value[property];
});
return value;
}
return function (input, propertyString, target) {
var properties = parseString(propertyString);
return input.filter(function (item) {
return getValue(item, properties) == target;
});
}
});
You could use this filter, like this:
$scope.routesToShow = $filter('CustomFilter')($scope.routes, 'origin.address.country', 'UK');
Here is an updated jsfiddle (notice the updated data structure): http://jsfiddle.net/moderndegree/86U29/44/
You can find more information on creating custom filters here:
https://docs.angularjs.org/guide/filter#creating-custom-filters
Simply.
var filter = function(obj){
return obj.origin[0].address[0].country === 'UK';
}
$scope.routesToShow = $filter('filter')($scope.routes, filter);
