Is there a way to pass a value from a Django view to an AngularJS inserted template?
In my view.py I have the code:
count_users = Profile.objects.filter(user_id__gte = 0).count()
context_dict = {'users': count_users}
return render_to_response('dashboard.html', context_dict)
In dashboard.html I am able to insert the user count into the html as follows:
{{ users }}
This works fine but dashboard.html uses AngularJS to insert some more html as follows:
<div ui-view class="fade-in-up">
</div>
Mt problem that the html file inserted by AngularJS does not respond to the:
{{ users }}
Is there a way to pass the value of users through to the AngularJS inserted HTML?
using ng-init you can attach your value into the $scope
<div ui-view class="fade-in-up" ng-init="User='{{user}}' " >
</div>
In your javascript do:
mainModule
.config(function($interpolateProvider) {
$interpolateProvider.startSymbol('{$');
$interpolateProvider.endSymbol('$}');
});
This way, if you want to bind an angular variable in the html, you use:
{$ variable $}
If you want to add a Django variable, you use:
{{ variable }}
And your code may work if you leave it as it is, and just add this configuration to the angular module.

I tried to keep my jinja code in CKEditor as it was after I toggle the view between code view and WYSIWYG view.
And I could get this result by adding below line in my config.js file
CKEDITOR.config.protectedSource.push(/\r|\n/g);
CKEDITOR.config.autoParagraph = false;
However, it does not work well for HTML code. For instance, if jinja code and html mixed together like this:
{% if name=='bob' %}
{{'hello bob'}}
{%else%}
{{ 'hello ' + name }}
{% endif %}
<p>Hello visitor</p>
Here is Demo on Fiddle JS
After this, when I change from code view to wyiwyg view in CKEditor, the HTML code just increase by one new line, and another new line for another toggle view as shown below:
I can't find what is wrong with HTML code, I just what to format jinja code only, how can I fix it? Thanks
Write these additional lines under your code
$("body").on("click", ".cke_button__source", ()=>{
// if(CKEDITOR.instances.editor1.mode==="source"){
let vtk = CKEDITOR.instances.editor1.getData();
// vtk = vtk.replace(/\n<p>/gm, "<p>");
vtk = vtk.replace(/^\s*[\r\n]/gm, "");
$(".cke_source").val(vtk)
// }
})

I have events page and event detail page.
When I place <h1>{{ Eventinfo.EventTitle }}</h1> to display title, the DOM does not get updated with new title. However, when I use <h1 [innerHTML]="Eventinfo.EventTitle"></h1>, I do get the update title in H1 tag.
Why do string interpolation <h1>{{ Eventinfo.EventTitle }}</h1> does not work?
try console in this function and reply with whatever data you are getting in console
public getEventInfo(id)
{
this.apiService.getEventInfo(id).subscribe((data : any) => {
this.Eventinfo = data.events.results[0];
});
console.log(this.Eventinfo); //view data in console
}
I am trying to add something like dynamic HTML using ng-bind-html but its not working with $scope variable
Here is my Angular code
1)My controller
$scope.name = "Parshuram"
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml("<div>{{name}}</div>");
Also that my string is dynamic
"<div><table class=" + "\"table table - bordered table - responsive table - hover add - lineheight table_scroll\"" + "><thead><tr><td>Name</td><td>Age</td></tr></thead><tbody><tr ng-repeat=" + "\"tr in dyna\"" + "><td>{{tr.name}}</td><td>{{tr.age}}</td></tr></tbody></table></div>"
So i cant replace every variable with $scope
2)- My HTML
<div ng-app="mymodule" ng-controller="myModuleController">
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
</div>
I got this output
{{name}}
My expected output is
Parshuram
Please can anyone help i am stuck at this point,does that $sce does not bind scope variable?? ..
I've created a working plnkr here: https://plnkr.co/edit/uOdbHjv1B7fr0Ra1kXI3?p=preview
the problem is that ng-bind-html is not bound to the scope.
you should manually compile the content.
a valid and reusable solution should be creating a directive, whitout using any external modules.
function compileTemplate($compile, $parse){
return {
link: function(scope, element, attr){
var parsed = $parse(attr.ngBindHtml);
function getStringValue() { return (parsed(scope) || '').toString(); }
scope.$watch(getStringValue, function() {
$compile(element, null, -9999)(scope);
});
}
}
}
<div ng-app="mymodule" ng-controller="myModuleController">
<div ng-bind-html="thisCanBeusedInsideNgBindHtml" compile-template></div>
</div>
ng-bind-html does what it says on the tin: it binds html. It doesn't bind angular template code into your dom.
You need to do this instead:
$scope.thisCanBeusedInsideNgBindHtml =
$sce.trustAsHtml("<div>"+$sanitize(name)+"</div>");
To do this you'll want to include the module ngSanitize from the javascript angular-sanitize.js. See https://docs.angularjs.org/api/ngSanitize
If you want to insert some html that includes angular directives then you should write your own custom directive to do it.
In your html just use
{{name}}
The {{var}} notation is to be used in the HTML code to evaluate that variable.
You can do :
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml('<div ng-bind="name"></div>');
Sorry I make another answer.
If you have
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml("<div>{{name}}</div>");
Then you can do
var str = "<div>{{name}}</div>";
var output = str.replace('{{name}}', $scope.name);
It seems to be the only option.
I am learning AngularJS at the moment and I am a little confused about the MVC separation of code throughout the DOM/file structure when using AngularJS.
I learn best when I work on a project. Right now I am working on a simple counter that adds a whole number when a button is pushed. I only have one way working and I am thinking of a better way to do this.
Right now I have this working in the code I am working on from AngularJS documentation itself.
I am probably crazy thinking that this cannot be the best way to do this. From my understanding ng-click is a directive that triggers a specific scope of code within the controller.
Why is Increment code inline within the DOM? As a MVC, should the code be organized to not be all over the place, such as in the main controller.js? I have tried to put the increment += function in a counter object, but could not get it to work, see jsFiddle.
<div ng-controller="MyCtrl">
<button ng-click="char">Charged</button>
<span>Total: {{ count }}</span>
</div>
I get that Apps view information based on expressions, filters, and directives. Directives bind to HTML to change behavior of the HTML. Clicks (with Directive selectors) controllers triggers AngularJS to run functions to update data without the entire page being reloaded.
So the Model is the whole setup.
The View is the expressions, filters, and directives.
Controller is the JS file of code that has objects and functions needed for the HTML Directives.
The example of the documentation has inline controller in the directive ng-click within the button tag…
Does anyone have any advice? Thank you.:)
There is a correct way of doing that in angular via a controller:
http://jsfiddle.net/zhxztysy/1/
Your fiddle was like this
<div ng-controller="MyCtrl">
<button ng-click="char">Charged</button>
<span>Total: {{ count }}</span>
</div>
function MyCtrl($scope) {
$scope.count = 0;
$scope.count = Function (char) {
$scope.count += char;
};}
Changed to this
<div ng-controller="MyCtrl">
<button ng-click="charge(5)">Charged</button>
<span>Total: {{ count }}</span>
</div>
function MyCtrl($scope) {
$scope.count = 0;
$scope.charge = function (char) {
$scope.count += char;
};
}
Can also extended like this
<div ng-controller="MyCtrl">
<button ng-click="charge()">Charged</button>
<span>Total: {{ count }}</span>
</div>
function MyCtrl($scope) {
$scope.count = 0;
$scope.chargingCount = 5;
$scope.charge = function () {
$scope.count += $scope.chargingCount;
};
}
I edited your jsfiddle to work. You have made a syntax error (bound $scope.count to a function and tried to add numbers to it later on)
I have this template tags in my html code
{{ djangoVar}} //Django template tag
{$ angularVar $} //AngularJS template tag
How can I assign {{ djangoVar}} to {$ angularVar $} in my html?
Something like:
{% {$ angularVar $} = djangoVar %}
The angularVar must be assigned with javascript code. So, in your django template you can do something like
<script>
var django_variables = {};
django_variables.djangoVar = {{ djangoVar }};
</script>
So you declare a django_variables global variable. Then, in your angular controllers you can do:
function MyController($scope) {
$scope.angularVar = django_variables.djangoVar;
}
The important thing is to run the 1st snippet inside a normal django html template that the context will be passed and {{ djangoVar }} will get its value.
