$parse.assign(..) is not a function Angular JS version 1.4.3

I am facing this problem while selecting file and showing its name on span.
So basically I am trying that whenever I select some file I want to change the span Tag. This is my view
<form name="fileUploadForm" ng-submit="submitFile(fileUploadForm.$valid)">
<div class="form-group upload-btn-wrapper">
<input type="file" class="form-control" id ="myFileField" file-input="patient_file" required />
<button class="csv-upload-btn">choose file</button>
<span id="file-chosen">{{ patient_file }}</span>
</div>
<div class="form-group">
<input type="submit" value="Upload" class="btn btn-primary">
</div>
</form>
following is my directive code
(function() {
angular.module('practimyze.dashboard')
.directive('csvUploader', ["$parse", function($parse) {
return {
restrict: 'EA',
templateUrl: "dashboard/breakdown/csv-uploader/csv-uploader.tpl.html",
replace: true,
controller: function($scope, valueHandler, Auth, $rootScope, blockUi, DashboardApi, fileUploadService, apiLinks, toaster){
},
link: function(scope, element, attrs) {
var model = $parse(attrs.csvUploader);
var modelSetter = model.assign;
element.bind('change', function() {
scope.$apply(function() {
modelSetter(scope, element[0].patient_file);
});
});
}
};
}]);
})();
Initially I did this
$parse.assign(scop, element[0].files);
this was getting me error that parse has not function assign. Then I changed it to what i have written now it says (modelSetter is not a function).
I am not sure where i am doing wrong, Please help me out thanks

this is the fiddle link, it seems to be working perfect there fiddle link

Initializing the date on a datetimepicker via the model

I'm trying to use the angular date time picker. The problem is that I'm loading the data from the model, the picker doesn't seem to bind the value.
If i just set the value manually to a date, it works, but when it's loaded from the model, it doesn't set the picker to the correct value.

I'm using the http://tarruda.github.com/bootstrap-datetimepicker/assets/js/bootstrap-datetimepicker.min.js datetimepicker for angular.
angular:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.date = '01/02/1983 01:02:03';
});
app.directive('datetimez', function() {
return {
restrict: 'A',
require : 'ngModel',
link: function(scope, element, attrs, ngModelCtrl) {
element.datetimepicker({
dateFormat:'dd/MM/yyyy',
timeFormat: 'hh:mm:ss',
}).on('changeDate', function(e) {
ngModelCtrl.$setViewValue(e.date);
scope.$apply();
});
}
};
});
HTML:
<div class="container container-fluid" ng-controller="MainCtrl">
2+2={{2+2}}, var1={{var1}}
<form class="form-horizontal" novalidate name="form" ng-submit="submit()">
<div class="well">
<div id="date" class="input-append" datetimez ng-model="var1">
<input data-format="dd/MM/yyyy hh:mm:ss" type="text" ng-value="date"></input>
<span class="add-on">
<i data-time-icon="icon-time" data-date-icon="icon-calendar"></i>
</span>
</div>
</div>

It's because you are using a string and not a date object:
app.controller('MainCtrl', function($scope) {
var date = new Date(1983, 1, 2, 1, 2);
$scope.date = date;
});

I recommend going with MomentJS for shorthand.

directive not generating html

I am having a problem with my code basically i have this span (dynamically created via ng-repeat)
<span my-size id="abc"></span>
<span my-size id="def"></span>
<span my-size id="ghi"></span>
what I need to achieve is to get the id of each span and split its character and created checkbox and used the split[] i get when i split the id to be its value
<span id="abc">
<input type="checkbox" value="a">
<input type="checkbox" value="b">
<input type="checkbox" value="c">
</span>
<span id="def">
<input type="checkbox" value="d">
<input type="checkbox" value="e">
<input type="checkbox" value="f">
</span>
<span id="ghi">
<input type="checkbox" value="g">
<input type="checkbox" value="h">
<input type="checkbox" value="i">
</span>
could anyone help me do this in angular js directives
this is all i have so far :
myApp.directive('mySize', function () {
return {
restrict: 'E',
scope: { html: '#' },
template: '<span ng-bind-html="html"></span>',
link : function (scope, element, attrs) {
scope.html="<h1>sample html </h1>";
}
}
});
I can't go further since my directives wont generate html tags

I'm not sure what your initial intention was when writing the directive, because there is really no need to either use a link-function or ng-bind-html.
For what you've asked the directive could be as simple as:
(function (app, ng) {
'use strict';
app.directive('mySize', function () {
return {
restrict: 'A',
scope: { id: '#id' },
template: '<input type="checkbox" data-ng-repeat="char in id track by $index" value="{{ char }}">'
}
});
}(angular.module('app', []), angular));
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.1/angular.min.js"></script>
<div data-ng-app="app">
<span data-my-size id="abc"></span>
<span data-my-size id="def"></span>
<span data-my-size id="ghi"></span>
</div>
Edit
If you you want to add extra information just fiddle with the template. E.g.:
(function (app, ng) {
'use strict';
app.directive('mySize', function () {
return {
// actually obsolute, because it's the default setting
restrict: 'A',
// reusing the directive name to simplify the required view-html,
// but mapping it to a more fitting name when used internally
scope: { str: '#mySize' },
// the actual template (this time using a label)
template: '<label data-ng-repeat="char in str track by $index"><input type="checkbox" value="{{ char }}"> {{ char }}</label>'
}
});
}(angular.module('app', []), angular));
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.1/angular.min.js"></script>
<div data-ng-app="app">
<div data-my-size="abc"></div>
<div data-my-size="def"></div>
<div data-my-size="ghi"></div>
</div>

It doesn't work because you restricted it's usage to element and use it as attribute. Change restrict: 'E' to restrict: 'A'.

var app = angular.module('app', []);
app.directive('mySize', function($sce) {
return {
restrict: 'EA',
scope: {
id: '#'
},
template: '<label ng-repeat="i in array"><input type="checkbox" ng-value="i" >{{i}}<label>',
link: function(scope, element, attrs) {
scope.array = scope.id.split("")
}
}
});
app.controller('homeCtrl', function($scope) {
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="homeCtrl">
<span my-size id="abc"></span>
<span my-size id="def"></span>
<span my-size id="ghi"></span>
</div>
</div>

The directive can look like this:
.directive('mySize', function() {
return {
restrict: 'AE',
link: function(scope, element, attrs) {
element[0].id.split('').map(function(el) {
element.append('<label><input type="checkbox" value="' + el + '"> ' + el + '</label>');
});
}
}
});

How data is passed from custom directive view to controller?

code for the directive template
//"textBox.html"
<div class="well">
<label class="control-label">Text</label>
<div class="controls">
<input id="label" type="text" class="txt span3" ng-model="label" placeholder='Label for text field...'>
<input type="text" class="span3" ng-model="value" placeholder='Default value...'>
<input type="text" class="span3" ng-model="helpText" placeholder="Help text...">
<input type="checkbox" class="span1" ng-model="required" ng-true-value="true" ng-false-value="false">Required
<input type="checkbox" class="span1" ng-model="advanced" ng-true-value="true" ng-false-value="false">Advanced?
<img src="../../images/bullet_cross.png" alt="Remove" style="cursor: pointer" id="text" border="0" ng-click="deleteField($event)">
</div>
</div>
directive is using like this in main html page
//"algorithm.html"
<text-box></text-box>
controller for the custom directive
//"controller.js"
var algorithm = angular.module('algorithmController',[]);
/***********directive to render text field***********/
algorithm.directive('textField' , function(){
return{
restrict: 'E',
templateUrl: '../partials/algorithm/textBox.html',
require: 'ngModel',
replace: true,
link: function(scope, iElement, iAttrs, ngModelCtrl) {
// how should i get updated data(i.e. if user change after typing) over here entered by user??
}
};
});

You can create an isolate scope using the '=' syntax, which will create two way binding to your controller and the directive. You don't even necessarily need ngModel required in your directive.
.directive("textField", function () {
return {
restrict : "E",
template : "<input type='text' ng-model='val'/>",
scope : {
val : "="
}
};
});
Here is a very simple example doing what you requested;

using datepicker on selecting date value not binding to model Angular js

i am using datepicker but here facing problem regarding model value not binding to model when i select date its nothing happen, any one can tell me where i am doing wrong must be appreciated. here i am sending my code.Showing date picker just problem after selecting date value not not binding to ng-model="user.dob".
signUpview.html
<div class="col-md-6">
<label for="datepicker" class="col-lg-5 form-label">Date Of Birth:</label>
<div class="col-lg-7">
<input type="text" class="form-control dateBirth" ng-model="user.dob" id="datepicker" name="datepicker" datepicker placeholder="Date Of Birth" required/>

<small class="error errorFields" ng-show="newUser_form.datepicker.$error.required"> Date is required.</small>
</div>
</div>
</div>
datepickerDirective.js
app.directive('datepicker', function() {
var linker = function(scope, element, attrs) {
element.datepicker().on('changeDate', function(){
console.log(scope);
$(".datepicker").hide();
});
}
return {
require: 'ngModel',
restrict: 'A',
link: linker
}
});

you can use ngModel.$setViewValue update the model property
app.directive('datepicker', function() {
var linker = function(scope, element, attrs,ngModelCtrl) {
element.datepicker().on('changeDate', function(){
console.log(scope);
ngModelCtrl.$setViewValue(value);//value is datepicker selected date;
$(".datepicker").hide();
});
}
return {
require: 'ngModel',
restrict: 'A',
link: linker
}
});
