Angular - $scope.myForm.$setPristine() is undefined

Form is not cleared after saved record in angularJs. I'm trying to reset form many ways, but form is not reset.
My angularjs version is 1.4.8.
This question is also a duplicate, but I tried what stack overflow users said. That has not worked for me.
Looking for a positive reply
Thank you.
Html code:
<form name="myForm" id="myForm" novalidate>
<input type="hidden" name="forumValue" ng-model="fid.forumValue"
id="forumValue" placeholder="fourm Id" />
<div class="form-group row">
<label for="inputAnswer" class="col-sm-2 col-form-label">Answer</label>
<div class="col-sm-10">
<textarea rows="10" name="answer" class="form-control"
ng-model="fid.answer" required></textarea>
</div>
</div>
<div class="form-group row">
<div class="col-sm-2"></div>
<div class="col-sm-8">
<button type="button" class="btn btn-success"
ng-click="saveUserAnswer(fid)">Post Your Answer</button>
</div>
</div>
</form>
Controller Code:
$scope.saveUserAnswer = function(fid) {
UserRepository.saveUserAnswer(fid).then(
function(response) {
var status = response.message;
if (status == "success") {
alert("posted success");
$scope.UserAnswer=getUserOnIdAnswer(fid.UserValue);
$scope.myForm.$setPristine();
$scope.myForm.$setUntouched();
$state.go('UserAnswer');
}
else {
$scope.User=response;
alert("posted Fail,Please correct the details..!!");
}
});
};

Is your form wrapped in an ng-if statement? If so, the form might be inside a child scope, and you might try:
Option A
Replace your ng-if with an ng-hide.
Option B
Bind the form to an existing object on the parent scope:
$scope.myData = {};
$scope.saveUserAnswer = function(fid) {
...
};
Then in your HTML, refer to the form on the parent scope:
<form name="myData.myForm" id="myForm" novalidate>
</form>

I have attempted to recreate your problem but without the call to the UserRepository just to confirm that we can set the form $pristine value to true and to reset the form.
<form name="form.myForm" id="myForm" novalidate>
<input type="hidden" name="forumValue" ng-model="fid.forumValue" id="forumValue" placeholder="fourm Id" />
<div class="form-grou`enter code here`p row">
<label for="inputAnswer" class="col-sm-2 col-form-label">Answer</label>
<div class="col-sm-10">
<textarea rows="10" name="form.myForm.answer" class="form-control" ng-model="fid.answer" required></textarea>
</div>
</div>
<div class="form-group row">
<div class="col-sm-2"></div>
<div class="col-sm-8">
<button type="button" class="btn btn-success" ng-click="saveUserAnswer(fid)">Post Your Answer</button>
</div>
</div>
</form>
<pre>{{form.myForm.$pristine}}</pre>
and the controller code like so :
$scope.form = {};
$scope.saveUserAnswer = function(fid) {
$scope.form.myForm.$setPristine();
$scope.fid = {};
//omitted the user repository code
};
The above will set the pristine value of the form to true and also reset the value of fid on click of the button.
EDIT
Also the call to your repository function should be in this format:
UserRepository.saveUserAnswer(fid).then(
function(response){
//success
},
function(response){
//error
}
);

In controller try to add '$scope.fid.answer=null;' after scope.myForm.$setPristine();
like this.
$scope.saveUserAnswer = function(fid) {
UserRepository.saveUserAnswer(fid).then(
function(response) {
var status = response.message;
if (status == "success") {
alert("posted success");
$scope.UserAnswer=getUserOnIdAnswer(fid.UserValue);
$scope.myForm.$setPristine();
$scope.myForm.$setUntouched();
$scope.fid.answer=null;
$state.go('UserAnswer');
}
else {
$scope.User=response;
alert("posted Fail,Please correct the details..!!");
}
});
};

How to add a control to a input file using angularjs?

I want to require an input of type file using angularjs without using the attribute required in the HTML code.
My interface is : enter image description here
I want to get an alert after hitting the button submit.
This is what I have done : enter image description here
function DatabaseCtrl($scope, $http, predefineds, locationSearch, queries, database, $window) {
var credentials = {
fileName: ""
};
$scope.credentials = credentials;
$scope.uploadToFolder = function() {
if( $scope.credentials.fileName.length<1 ) {
$window.alert("Please select a file!");
return false;
}
database.uploadToFolder($scope.credentials.fileName, true);
};
The HTML code :
<form role="form" name="frmUploadFolder" ng-submit="uploadToFolder()">
<div class="box">
<h2>
<span ng-show="isUserFile">File directory browser :</span>
<button type="button" ng-show="isUserFile" class="btn btn-default">See file(s)</button>
<button type="button" ng-show="!isUserFile" class="btn btn-default">Upload file(s)</button>
</h2>
<div class="content">
<p>
<label ng-show="isUserFile" >Please specify a file, or a set of files:</label><br>
<input type="file" ng-show="isUserFile" name="datafile" id="fileName" ng-model="credentials.fileName" size="20" required multiple>
<button type="submit" ng-show="isUserFile" class="btn btn-default" >Upload</button><br>
</p>
<div ui-if="!tree.length" class="message">
<p ui-if="!tree.loading">
<span ng-show="!isUserFile">Empty directory</span>
</p>
</div>
</div>
</div>
</form>
The service js :
angular.module('referl.services').factory('database', function($http, channel, $rootScope) {
var database = {
uploadToFolder: function(fileName, navigateOnSuccess) {
var parameters = {
fileName: fileName
};
$http.get("api/database/uploadToFolder", {params: parameters})
.success(function(response) {
if(response.error) {
alert(response.error);
} else {
if (navigateOnSuccess) {
alert("Navigation On Success !");
}
}
});
}
};
Any help please?

For some reason angular does not fully support binding a model element to a file input. The directive approach is generally the accepted work around, but within your controller you can also use document.getElementById("filename") to get a reference to the filename input and grab its value.

AngularJS doesn't update view until refresh?

I am currently facing a problem, which has to do with views. I am making an app, which allows for users to create polls. When the poll that a user creates is submitted, I call a POST route to store it:
$scope.userVal = Auth.getCurrentUser();
$http.post('/api/users/update' + $scope.userVal._id, {polls: $scope.polls}).success(function(res){
//console.log("res: ", res);
});
Essentially, I get the user info,and use his id to store the new poll in a schema-defined value called polls.
Now, when a user clicks a button, I display the polls that were created via a ng-view:
$scope.pollView= function(){
$scope.userVal2 = Auth.getCurrentUser();
$scope.userVal2 = $scope.userVal2.polls;
$scope.button = true;
};
In the html, I simply iterate over $scope.userVal2. My problem comes when I try to view a newly created poll. The poll does not initially show up, but if I refresh the page, then it shows up. Is there any reason for this? Does this have to do with the async calls?
Any help would be appreciated!
edit:
Controller:
'use strict';
angular.module('voteApp')
.controller('WallCtrl', function ($scope, $http, Auth) {
$scope.items = [];
$scope.title;
$scope.button = false; //set default to the new poll
$scope.polls = [];
$scope.items.push({id:1, upvotes:0, text:""});
$scope.items.push({id:2, upvotes:0, text:""});
$scope.addOptions = function(){
$scope.items.push({id:$scope.items.length +1, upvotes:0, text:""});
};
$scope.process = function(name, values){
$scope.polls.push({title:name, options:values});
$scope.title = ""; //reset the values for the next poll
$scope.items = [];
$scope.items.push({id:1, upvotes:0, text:""});
$scope.items.push({id:2, upvotes:0, text:""});
$scope.userVal = Auth.getCurrentUser();
$http.post('/api/users/update' + $scope.userVal._id, {polls: $scope.polls}).success(function(res){
//console.log("res: ", res);
});
};
$scope.newView= function(){
$scope.button = false;
};
$scope.pollView= function(){
$scope.userVal2 = Auth.getCurrentUser().polls
$scope.button = true;
};
$scope.delete = function(val){
$scope.polls = $scope.polls.filter(function(returnableObjects){
return returnableObjects.title !== val.title;
});
};
});

<div class="polldeco">
{{poll[0].title}}
<button class="btn buttondeco" ng-click="delete(poll)">Delete</button>
</div>
</div>
</div>

Some ideas:
$scope.userVal2 = Auth.getCurrentUser().polls is using the old version prior to the creation of a new poll? Maybe this could be changed to something like Auth.getCurrentUser().then(...). Either way, ensure that the call to getCurrentUser() is returning new data.
ng-view is cached. When a template is initially requested, it gets stored in the $templateCache. If this template is rendered on the backend for display in as a partial (eg: ng-view) and it is not static content, then you will have to invalidate the cache to update the view.
Consider having the backend return the new poll from $http.post('/api/users/update' ...) and adding it to the list used by ng-repeat. Something like:
$scope.process = function(name, values) {
$scope.polls.push({title:name, options:values});
...
$http.post('/api/users/update' + $scope.userVal._id, {polls: $scope.polls}).success(function(poll){
$scope.polls.push(poll);
});
};
...
<div ng-repeat="poll in polls">
<div class="polldeco">
{{poll[0].title}}
<button class="btn buttondeco" ng-click="delete(poll)">Delete</button>

Angularjs email form field not clearing/resetting after model binding reset

Hey so I have a form which has three fields name,email and phone.
<div ng-show="Nerd.adding">
<form class="col-sm-6" name="Nerd.nerdAddFrm" novalidate >
<div class="form-group">
<label for="inputName">Name</label>
<input type="text" class="form-control" id="inputName" placeholder="Name" ng-model="Nerd.nerd.name" required >
</div>
<div class="form-group">
<label for="inputEmail">Email</label>
<input type="email" class="form-control" id="inputEmail" placeholder="Email" ng-model="Nerd.nerd.email" required >
</div>
<div class="form-group">
<label for="inputPhone">Phone</label>
<input type="text" class="form-control" id="inputPhone" placeholder="Phone" ng-model="Nerd.nerd.phone" required >
</div>
<button ng-click="Nerd.saveNerd(Nerd.nerd)" type="submit" class="btn btn-primary">Submit</button>
<button ng-click="Nerd.load()" type="button" class="btn btn-default">Cancel</button>
</form>
</div>
As you can see the cancel button calls a Nerd.load() function in the controller. The controller basically resets the view and resets all the binded data to the model.
Nerd.load = function () {
Nerd.editing = false;
Nerd.adding = false;
Nerd.nerd = [];
nerdResource.query(
function (data) {
Nerd.nerds = data;
}
);
};
You can see that I am setting Nerd.nerd equal to an empty array. This should empty out the form fields data. It works fine for Name and Phone. But when I go back to the page it still shows what was last typed. There is no page reload as I am showing and hiding divs based on controller variables. EG <div ng-show="Nerd.adding">. Can anyone help me out with this?
I am on angularjs version 1.3.14. Any help on this would be great.
Thanks.

You need to attach these variables to your $scope like so:
$scope.Nerd.load = function () {
$scope.Nerd.editing = false;
$scope.Nerd.adding = false;
$scope.Nerd.nerd = [];
nerdResource.query(
function (data) {
$scope.Nerd.nerds = data;
}
);
};
Also, I think you should set $scope.Nerd to an empty object like:
$scope.Nerd = {};
instead of setting it to an empty array. You need to use $scope when interacting with the view. This code doesn't look the angular the way it is currently written.

If you can try according some way.
Nerd.load = function () {
Nerd.editing = false;
Nerd.adding = false;
Nerd.nerd = [];
nerdResource.query(
function (data) {
Nerd.nerds = data;
Nerd.nerd = []; // Put here and array make Empty
}
);
};

Can't access form inside AngularJS controller

Can't access form variable from my controller, when i try to access it by $scope.locationForm i've got 'undefined', but when i call console.log($scope) i can see in console there have loactionForm.
My HTML code
<div ng-controller="LocationsController as ctrl">
<form class="form-inline" name="locationForm">
<div class="form-group">
<!-- <div class="input-group"> -->
<label for="location-name">Название населенного пункта</label>
<input required
name="name"
ng-model="ctrl.location.name" type="text" class="form-control" id="location-name" placeholder="Название населенного пункта">
<label for="location-name">Район</label>
<select required
name="region_id"
ng-model="ctrl.location.region_id"
ng-options="region.id as region.name for region in ctrl.regions" class="form-control" placeholder="Название района"></select>
<input ng-click="ctrl.save()"
ng-disabled="locationForm.$invalid" type="submit" class="btn btn-default" value="Cохранить">
<a class="btn btn-default" ng-click="ctrl.reset()" ng-show="locationForm.$dirty">Сброс</a>
<!-- </div> -->
</div>
</form>
My Controller code:
function LocationsController($scope, Location, Region, $q) {
var lc = this,
l_index;
lc.form ={};
lc.regions = lc.locations = [];
lc.regions = Region.query();
lc.regions.$promise.then(function(data) {
lc.locations = Location.query();
});
lc.getRegion = function (id) {
return lc.regions.filter(function(obj) {
return obj.id == id;
})[0].name;
};
console.log($scope);
// console.log($scope.locationForm);
lc.reset = function () {
lc.location = new Location;
}
lc.reset();
};

The problem is when the LocationsController is initialized the form element is not yet compiled. So one possible hack is to use a timeout like
function LocationsController($scope, Location, Region, $q, $timeout) {
//then later
$timeout(function(){lc.reset();})
}
