Losing scope when using ng-include for recursion ( Updating object at run time, not reflecting the changes on child template) in angularjs

I'm using ng-include for recursion. it's loading correct at first time but when I change anything in the object at run time, it doesn't reflect the changes on html. ng-include will create a child scope for that, so its not getting changes from parent scope. How can I bind the scope or reflect the changes in the html? Below is the code snippet for main.html
<div ng-switch on="value.length>0">
<div ng-switch-when="true">
<div ng-init="item = value[0];" ng-include="'test/views/partialTemp.html'">
</div>
</div>
</div>
In Partial Template
<div class="row" ng-repeat="(key, result) in item" ng-if="item ">
.......
<div ng-switch on="result.length > 0 ">
<div ng-repeat="tempValue in result">
<div ng-switch-when="true">
<div ng-init="item = tempValue;" ng-include="'test/views/partialTemp.html'"></div>
</div>
</div>
</div>
....
</div>
In JS File
onRadioButtonChange = function(key, value, item) {
var self = this;
self.serviceObj.Response.values = self.updateServiceObject(self.serviceObj.Response.values, key, value, false); // Updating the actual object which came from service
self.objectToShow = JSON.parse(JSON.stringify(self.serviceObj)); // Taking the actual object which will show in the HTML
self.objectToShow.Response.values = self.filterObjectToShow(self.objectToShow.Response.values); // it'll add/remove the child radio button
}
objectToShow is the object which I'm using to render the html

How to call multiple angularjs service calls from within nested ng-repeat

I am making a simple sports goods shopping app in AngularJs.
I am in a situation where I have three nested ng-repeats.
First loop: Get the brand name. I have written angularjs service that calls the rest endpoint to fetch the lists of brands (Adidas, Yonex, Stiga, etc). I am calling this service as soon as the page(controller) gets loaded.
Second loop: For each brand, I want to display the category of products they are offering. Inside this loop, I want to execute a function/service that will take the brand name as input and get all the categories for the brand. For this, I also have an angularjs service that calls the rest endpoint to fetch the list of categories for a given brand name.
Third loop: For each brand and category, I want to display the products in that category. Inside this loop, I want to execute a function that will take the brand name and category as input and get all the products in that category. I an angularjs service call which will call the rest endpoint to fetch the products given the brand name and category.
Sample data set:
Adidas
-----T-Shirts
----------V-Neck
----------RoundNeck
-----Shoes
----------Sports Shoes
----------LifeStyle Shoes
Yonex
-----Badminton Racquet
----------Cabonex
----------Nanospeed
-----Shuttlecocks
----------Plastic
----------Feather
Stiga
-----Paddle
----------Procarbon
----------Semi-carbon
-----Ping Pong Balls
----------Light Weight
----------Heavy Weight
Please note that because of some constraints I cannot have a domain object on the REST side to mimic the data structure shown above.
I want to display the above data in a tree-like fashion (something on the same lines as shown above possibly with expand/collapse options).
Below are the code snippets.
CONTROLLER:
(function () {
'use strict';
angular.module('SportsShoppingApp.controllers').controller('sportsController', ['sportsService', '$scope', function (sportsService, $scope) {
$scope.brands = [];
$scope.categories = [];
$scope.products = {};
$scope.getBrands = function () {
sportsService.getBrands()
.then(loadBrands, serviceError);
};
var loadBrands = function(response) {
$scope.brands= response.data;
};
$scope.getCategories = function(brand) {
sportsService.getCategories(brand)
.then(loadCategories, serviceError);
};
var loadCategories = function (response) {
$scope.categories = response.data;
};
$scope.getProducts = function(brand, category) {
sportsService.getProducts(brand, category)
.then(loadProducts, serviceError);
};
var loadProducts = function (response) {
$scope.products = response.data;
};
var serviceError = function (errorMsg) {
console.log(errorMsg);
};
$scope.getBrands();
}]);
}());
HTML:
<div class="well">
<div class="row">
<div id="sportsHeader" class="col-md-3">
<div ng-repeat="brand in brands.data">
<div class="row">
<div class="col-md-9">{{brand}}</div>
</div>
<div ng-repeat="category in categories.data" ng-init="getCategories(brand)">
<div class="row">
<div class="col-md-9">{{category}}</div>
</div>
<div ng-repeat="product in products.data" ng-init="getProducts(brand, category)">
<div class="row">
<div class="col-md-9">{{product}}</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
When I use the above HTML, only the brand names are displayed on the UI. The categories and their corresponding products are not displayed. I know that there is some overlapping that is happening. I am not sure if I am doing it the right way. I might be completely wrong with my approach. I am new to AngularJS. I want to know how to loop in nested ng-repeat so that each ng-repeat could call an angularjs service and also I want to display the data in the tree fashion as shown above. Can someone help me here?

I think that the ng-inits have to be placed on separate tags to the ng-repeats:
<div class="well">
<div class="row">
<div id="sportsHeader" class="col-md-3">
<div ng-repeat="brand in brands.data">
<div class="row">
<div class="col-md-9">{{brand}}</div>
</div>
<div ng-init="getCategories(brand)">
<div ng-repeat="category in categories.data">
<div class="row">
<div class="col-md-9">{{category}}</div>
</div>
<div ng-init="getProducts(brand, category)">
<div ng-repeat="product in products.data">
<div class="row">
<div class="col-md-9">{{product}}</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
You might have to juggle your bootstrap classes around also, moving ng-init is only to fix the angular part.

Move the ng-init directives outside of the ng-repeat to which they provide data.
<div class="well">
<div class="row">
<div id="sportsHeader" class="col-md-3">
<!-- MOVE init of categories here -->
<div ng-repeat="brand in brands.data" ng-init="getCategories(brand)">
<div class="row">
<div class="col-md-9">{{brand}}</div>
</div>
<!-- MOVE init of products here -->
<div ng-repeat="category in categories.data" ng-init="getProducts(brand, category)">
<div class="row">
<div class="col-md-9">{{category}}</div>
</div>
<div ng-repeat="product in products.data">
<div class="row">
<div class="col-md-9">{{product}}</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
The ng-init directive has a priority of 450; the ng-repeat, priority 1000. This means that when they are on the same element ng-init executes after the ng-repeat directive. The ng-repeat for categories.data won't execute its ng-init until it has a category. Thus its ng-init can't be used to populate the categories array.
Quick question. Is my approach correct ?
The approach works but it violates the Zen of Angular and the principles of an MV* Model View Whatever framework.
The model is the Single Source of Truth
Because the view is just a projection of the model, the controller is completely separated from the view and unaware of it. This makes testing a snap because it is easy to test your controller in isolation without the view and the related DOM/browser dependency.
--AngularJS Developer Guide -- Data-Binding
Having the ng-repeat and ng-init directives build the model creates a dependency that makes testing and debugging difficult. (As witnessed by this question.)
My advice is to learn how to build the model by chaining promises and using $q.all.

Directive take other directive's data after deletion

Edit: Thanks to Simon Schüpbach, I was able to resolve the issue by changing the template. See the end for the solution.
Let's preface this by saying that we are beginner to soft-intermediate in Angular.
On one of our project, we are using angularjs 1.4.x and also ng-cart (https://github.com/snapjay/ngCart). It worked great but then we were confronted with a demand from our client that created new weird issues.
We added fsCounter, as a directive, to the cart page so user can add or remove items. This all work great but the users also have the option to delete an item from the cart view. Deletion works as expected BUT it seems to affect the scope to the item that takes it place.
Let me make it clearer :
Let's say we have 2 products in our cart page, it displays something like that
Product_1 {price} {counter} {total} delete_btn
Product_2 {price} {counter} {total} delete_btn
Each fsCounter is its own scope
return {
restrict: "A",
scope: {
value: "=value",
index: "=index"
},
link: //other logic
However when we delete the first item, visually and in the directives, the data seems to shift. So our second row will now inherit the first row's counter.
Directive's data looks like this:
Product_1:
itemId:3,
quantity:2,
{other data}
Product_2:
itemId:8,
quantity:5,
{other data}
But once we delete the first directive (We get the scope, remove the DOM element, destroy the scope) the second directive will now have this data:
Product_2:
itemId:3,
quantity:2,
{other data}
Here is the template code :
<div class="unItem" ng-repeat="item in ngCart.getCart().items track by $index">
<div class="photo"><img src="{[{ item.getImage() }]}" alt=""></div>
<div class="details">
<h3>{[{ item.getName() }]} <span>{[{ item.getPrice() | currency:$}]}</span></h3>
<md-select ng-model="attributes" placeholder="Attribut" class="select-attribut" ng-show="item.hasAttributes()" ng-change="item.updateSelected(attributes)">
<md-option ng-repeat="attr in item.getAttributes()" ng-selected="attr == item.getSelected()" ng-value="attr">{[{ attr }]}</md-option>
</md-select>
</div>
<div class="quantity">
<div fs-counter-dynamic value="itemQuantity"
data-min="1"
data-max="999"
data-step="1"
data-addclass="add-quantity"
data-width="130px"
data-itemid="{[{ item.getId() }]}"
data-editable
ng-model="itemQuantity"
name="quantity" id="quantity-{[{ item.getId() }]}",
index="{[{ item.getId() }]}"
></div>
</div>
<div class="total">Total : {[{ item.getTotal() | currency }]}</div>
<div class="delete"><a ng-click="ngCart.removeItemById(item.getId());"></a></div>
</div>
Is this normal behavior? Is there any way to force the directive to keeps its own data? From what I've understood, each directive has its own scope, so what I think happens is that, when we remove the first one, it keeps the data stored in some kind of array that says "directive 1 data is : " and when we delete the first directive, the second one becomes the first.
So basically, are we doing anything wrong or is there anyway to remap the data?
Hope it was clear enough,
Thanks!
Edit: added html code
Edit2: Answer :
New FsCounter template looks like this:
<div fs-counter-dynamic value="item._quantity"
data-min="1"
data-max="999"
data-step="1"
data-addclass="add-quantity"
data-width="130px"
data-itemid="{[{ item.getId() }]}"
data-editable
ng-model="item._quantity"
name="quantity" id="quantity{[{ item.getId() }]}"
></div>

Do you know ng-repeat, then you don't have such problems
<div ng-repeat="product in products">
<fs-counter index="product.index" value="product.value"></fs-counter>
</div>
and in your controller
$scope.products = [
{index:1, value:"Cola"},
{index:2,,value:"Fanta"}
]
to remove an element you just have to do
$scope.products.splice(0,1);
Edit:
I suggest to save all necessary data inside the item you use inside ng-repeat. Your problem is, that you mix data from array with other data from your $scope. It is possible to $watch changes in your directive, but if you set them with ng-repeat everything is done automatically.
$scope.products = [
{index:1, name:"Cola", price:1.50, image:"your/path.png", attributes:{...}},
{index:2, name:"Fanta", price:1.40, image:"your/path.png"}
]
And then in your html
<div class="unItem" ng-repeat="item in ngCart.products track by $index">
<div class="photo"><img ng-src="item.image" alt=""></div>
<div class="details">
<h3>{{item.name}} <span>{{item.price | currency}}</span></h3>
</div>
<div class="quantity">
<div fs-counter-dynamic value="item.quantity"
data-min="1"
data-max="999"
data-step="1"
data-addclass="add-quantity"
data-width="130px"
data-itemid="item.index"
data-editable
ng-model="item.quantity"
name="quantity" id="{{'quantity-' + $index}}",
index="item.index"
></div>
</div>
<div class="total">Total : {{ item.price * item.quantity | currency }}</div>
<div class="delete"><a ng-click="ngCart.removeItemById(item.index);"></a></div>
</div>

How do I access this scope variable inside of isolated scope directive?

This is my situation in psuedo code
<div data-ng-controller="test">
<div isolated-directive>
<select ng-model="testControllerScopeVar">...</select>
</div>
<div ng-if="some condition that uses testControllerScopeVar"></div>
</div>
This worked perfectly before I added isolated-directive, now that it is added (scope: true) the ng-if no longer works because I think it is getting eat up inside of the directive.
What is the most efficient way to get this working without touching the structure of the html and isolated-directive?

Well it seems once I know the solution, it is so simple
<div data-ng-controller="test as testCtrl">
<div isolated-directive>
<select ng-model="testCtrl.testControllerScopeVar">...</select>
</div>
<div ng-if="testCtrl.testControllerScopeVar == 'whatever'"></div>
</div>
ControllerAs allows me to specifically access the right scope and works perfectly, thanks all for your time and input

One approach is to map the controller variable into your isolated scope and attach the isolated scope variable to your internal ng-model.
So your HTML would look like this:
<div data-ng-controller="test">
<div isolated-directive="testControllerScopeVar">
<select ng-model="isolatedScopeVar">...</select>
</div>
<div ng-if="some condition that uses testControllerScopeVar"></div>
</div>
And your directive declaration would look like this:
app.directive('isolatedDirective', function () {
return {
scope: {
isolatedScopeVar: '=isolatedDirective'
}
};
});

You can try jQuery to get the value and assign it to a new scope variable. Something like this
HTML
<div ng-app="TestApp">
<div data-ng-controller="test">
<div isolated-directive>
<input id="isolatedVar" ng-model="testControllerScopeVar" />
</div>
<div>
{{isolatedVar}}
</div>
</div>
</div>
JS
var app = angular.module('TestApp', []);
app.controller('test', function($scope) {
var element = angular.element(document.querySelector('#isolatedVar'));
element.bind('keyup', function() {
$scope.isolatedVar = element.val();
console.log($scope.isolatedVar);
$scope.$watch('isolatedVar', function() {});
});
});
app.directive('isolatedDirective', function() {
return {
scope: true
};
});

how to assign array element value to ng-click in angular js

In my program I have an Array which consists of header name and function name.
I am using ng-repeat in a div which consists of a span tag. I want to add different functionality for each iterated span so I stored function name in array.
my html code is:
<div ng-repeat="header in header" ng-init="head=header">
<h4 class="headers">{{ header.name}}</h4>
<div class="arrow-up" ng-show={{ header.arrowup}} ng-click={{header.close}}> </div>
</div>
my angular code is:
$scope.header=[{"name":"Subsection Header #1","arrowup":"arrowup","close":"close()"}];
$scope.close = function() {
console.log(hello);
};
I want to assign close() to the ng-click and arrowup to ng-show. How can I assign them to ng-click and ng-show

change:
<div class="arrow-up" ng-show={{ header.arrowup}} ng-click={{header.close}}>
To:
<div class="arrow-up" ng-show="header.arrowup" ng-click="this[header.close]()">
<button>
CLOSE ME
</button>
</div>
DEMO= http://jsfiddle.net/Lvc0u55v/1788/

ng-click is the problem as i see,
<div class="arrow-up" ng-show="header.arrowup" ng-click="header.close"></div>
we need not give {{}} to ng-click and ng-show.
hope it helps.

First you need to pass a real functions to array:
function arrowUp(){
// ng-show needs to receive true or false
return true;
}
function close(){
// do something here
}
$scope.headers=[{"name":"Subsection Header #1","arrowup":arrowUp,"close":close}];
The bind them in a view:
<div ng-repeat="header in headers">
<h4 class="header">{{ header.name}}</h4>
<div class="arrow-up" ng-show="header.arrowup()" ng-click="header.close()"> </div>
</div>

You need to use the $eval method, you can read more about it here
$scope.$eval Executes the expression on the current scope and returns the result. Any exceptions in the expression are propagated (uncaught). This is useful when evaluating Angular expressions
HTML:
<div ng-controller="TestController">
<div ng-repeat="header in headers">
<h4>{{ header.name}}</h4>
<button type="button" ng-click="onExecuteFunctionFromString(header.close)">Click Here</button>
</div>
</div>
JS:
var myApp = angular.module('myApp', []);
myApp.controller('TestController', ['$scope', function($scope) {
$scope.headers = [{
"name": "Subsection Header #1",
"arrowup": "arrowup",
"close": "close()"
}];
$scope.close = function() {
console.log('hello');
};
$scope.onExecuteFunctionFromString = function(stringFunction) {
$scope.$eval(stringFunction)
};
}]);
Please see working example here
