Is there a way to populate mdDialog fields after the Dialog shows?

I have a simple mdDialog for editing form entries, that pops up when you double-click a grid row. The dialog appears and everything works, except I'd like to populate the fields in the dialog with the contents of the grid row. The problem is that I'm not sure where to actually do this, and every spot I've tried so far is accessed before the Dialog has actually been shown, so the HTML elements inside the dialog don't exist yet to be populated. Here's the method that calls the dialog:
$scope.showUpdateDialog = function(data) {
$mdDialog.show({
controller: UpdateDialogController,
scope: $scope.$new(),
templateUrl: 'js/admin/UpdateUsersDialog.html',
parent: angular.element(document.body),
clickOutsideToClose:true,
fullscreen:true
})
.then(function(answer) {
$scope.status = 'Updated User';
}, function() {
$scope.status = 'Update User Failed';
});
};
And here is the controller for it:
function UpdateDialogController($scope, $mdDialog) {
$scope.hide = function() {
$mdDialog.hide();
};
$scope.cancel = function() {
$mdDialog.cancel();
};
$scope.answer = function(answer) {
$mdDialog.hide(answer);
};
$scope.add = function(dialogdata) {
// For clarity I removed the contents of what happens with the add, as this part works fine.
};
}
Inside that templateUrl: 'js/admin/UpdateUsersDialog.html' are several elements, that all look like this:
<input type="text" class="form-control" id="updatelogin"
placeholder="Enter Name" data-ng-model="dialogdata.login" disabled />
I thought that the data-ng-model bit would take care of it (dialogdata.login etc. are all assigned variables before the dialog is kicked off) but it doesn't, so I was attempting to force it by doing something like this:
var ulogin = document.getElementById('updatelogin');
ulogin.setInnerHTML(content.login);
...but since the elements don't exist yet the 'ulogin' var keeps coming back as null. Is there a way to do this?

Okay after some babbaging I figured something out, maybe this can help others who hit a similar problem. The solution for me was to put everything into the onRowDoubleClicked method, which is called in the ag-grid when I double click a row in the grid:
function onRowDoubleClicked() {
var selectedRowNode = $scope.UserTableGrid.api.getSelectedNodes()[0];
var data = selectedRowNode.data;
$scope.login = data.login;
$scope.name = data.name;
$scope.email = data.email;
$scope.type = data.roles;
$scope.userId = $scope.getUserId($scope.login);
showUDialog(data);
function showUDialog(data) {
$scope.email = data.email;
$mdDialog.show({
controller: UpdateDialogController,
scope: $scope.$new(),
templateUrl: 'js/admin/UpdateUsersDialog.html',
parent: angular.element(document.body),
clickOutsideToClose:true,
fullscreen:true
})
.then(function(answer) {
$scope.status = 'Updated User';
}, function() {
$scope.status = 'Update User Failed';
});
}
function UpdateDialogController($scope, $mdDialog) {
$scope.hide = function() {
$mdDialog.hide();
};
$scope.cancel = function() {
$mdDialog.cancel();
};
$scope.answer = function(answer) {
$mdDialog.hide(answer);
};
$scope.add = function() {
//Close the Dialog
$scope.answer("Completed");
var userJson = {
"name" : $scope.name,
"login" : $scope.login,
"password" : "",
"roles" : $scope.type,
"email" : $scope.email,
"tpbUserId" : $scope.userId
};
var url = 'RobotDataInterface/User/updateUser';
var data = JSON.stringify(userJson);
$http.post(url, data).then(
function success(response) {
$scope.addUserCallback(response);
},
function failure(response) {
$scope.generalRestFailureCallback(response);
}
);
};
$scope.addUserCallback = function(data) {
console.log("User Updated!");
$scope.loadTableData();
}
}
}
This fixed what was a scoping issue, and allowed the fields in the templateUrl to get populated by tying them to those same values:
<input type="text" class="form-control" id="name"
placeholder="Enter Name" data-ng-model="name" />

How to empty(or reset) all the input fields on a form after successfull submission in AngularJS in following code?

I've a following controller code with me :
var app = angular.module('app_name');
app.controller("manageUsersController", [ "config", "$scope", "$http", "$mdToast",
function(config, $scope, $http, $mdToast) {
$scope.add = function() {
var userData = {
email : $scope.manageUsers.email,
password : $scope.manageUsers.password,
schoolId : '1',
name : $scope.manageUsers.name,
mobileNumber : $scope.manageUsers.mobileNumber
};
$http.post(config.webServicesUrl.postAddUser, userData, headerConfig).success(
function(data) {
displayToastMessage("User added successfully", $mdToast);
}).error(function(error) {
console.log(error.error);
});
}
}]);
All the HTML fields are input fields and are accessed using $scope object.
I tried with $setPristine but it didn't work.
Somebody please help me in setting all the fields to empty upon successful submission of form only in my code.
Thanks.

If you want to reset your form upon completion, I think you have to reset the $scope.manageUsers object manually once your post request has resolve:
$http.post(config.webServicesUrl.postAddUser, userData, headerConfig).success(
function(data) {
// has I don't know if you have other properties
// I reset each property manually,
// but you could probably do $scope.manageUsers = {}
$scope.manageUsers.email = null;
$scope.manageUsers.password = null;
$scope.manageUsers.name = null;
$scope.manageUsers.mobileNumber = null;
displayToastMessage("User added successfully", $mdToast);
}).error(function(error) {
console.log(error.error);
});

You can use $setPristine() here:
$http.post(config.webServicesUrl.postAddUser, userData, headerConfig).success(
function(data) {
displayToastMessage("User added successfully", $mdToast);
$scope.form.$setPristine(); // <---------here.
}).error(function(error) {
console.log(error.error);
});
Plnkr demo in action.

It should work for you.
$http.post(config.webServicesUrl.postAddUser,userData,headerConfig)
.success(function(data) {
$scope.manageUsers={};
displayToastMessage("User added successfully.", $mdToast);
}).error(function(error) {
console.log(error.error);
});

Angular Directive Element dynamic Template fields with its updated model value from controller?

I have <superhero> directive which has two directive
web-buttons to take of the form validation and post the updated
ngModel value to respective controller
fieldMap directive to generate the dynamic fields by object we are passing from respective controller
Here is the example which i have worked
directive attribute called saveFormFn will tell the button to call which function to invoked using enter attribute directive.
For example. After click save button it will call the function 'Ctrl1saveFormFn' from controller Ctrl1 .This function will make ajax post to save the form fields.
After updating the text fields with some content and click save,I have passed the current scope of the directive to respective controller (see console log). i could not get the updated fielddata value from current Scope.
$scope.Ctrl1saveFormFn = function(item){
_.each(item,function(currentScope){
console.log(currentScope)
// here i want to collect the form data with updated fielddata values
})
}
I am beginner.Am i on right path? Please advice

I've re-written your code because it was pretty hard to understand.
I would do it like this:
Use ng-include to load the template of your buttons. That's loading the control buttons edit and save.
Save your data in a variable in the superhero directive. Maybe it would be even better to store it in a separate service/factory.
Create a directive customForm that will create a form based on the supplied model that you're passing to its scope.
The main application logic is in the superhero directive because it is adding the controls save/edit to the DOM. If saving/editing is not only related to the superhero it would be better to do it in your main controller.
Please have a look at the demo below or in this jsfiddle.
angular.module('demoApp', [])
.directive('superhero', Superhero)
.directive('customForm', CustomForm)
.controller('mainController', MainController);
function Superhero() {
return {
restrict: 'E',
scope: {
formModel: "=",
},
template: '<div class="hero"><div ng-include="\'web-buttons.html\'"></div><custom-form model="formModel"></custom-form></div>',
controllerAs: 'superHeroCtrl',
controller: function ($scope) {
var self = this;
console.log('controller directive');
angular.extend(this, {
abilities: [],
editMode: false,
addStrength: function (data) {
self.abilities.push(data);
},
getStrength: function () {
return self.abilities;
},
showSave: function() {
self.editMode = true;
$scope.formModel.editMode = true;
},
hideSave: function() {
self.editMode = false;
$scope.formModel.editMode = false;
},
save: function() {
self.addStrength('can fly');
console.log(self.getStrength());
console.log('saving data now of form now...', $scope.formModel.data);
alert('saving data of form now: ' + self.getStrength()[0] + ' - ' + JSON.stringify( $scope.formModel.data, null, 2));
self.hideSave();
}
});
}
}
}
function CustomForm() {
return {
restrict: 'EA',
scope: {
model: '='
},
template: '<div ng-if="model.editMode" ng-repeat="formElement in model.fields" ng-include="formElement.template.url"></div>'
}
}

How to update model using angularjs, Django,Django rest framework

I have such json representation of a post by its id:
http://127.0.0.1:8000/update/1?format=json
{"title": "about me", "content": "I like program", "created": "2014-11-29T18:07:18.173Z", "rating": 1, "id": 1}
I try to update rating by button click:
<button ng-click="click(post.id)">Click me</button>
I have such javascript code:
<script>
var demoApp = angular.module('demoApp',['ngResource']);
demoApp.controller( 'AllPosts', function ($scope, $http)
{
$http.get('/blogpost/?format=json').success(function(data,status,headers,config)
{
$scope.posts = data.results;
$scope.predicate = '-title';
$scope.click = function(post_id, $resource){
var Post = $resource('/update/:PostId ',{PostId:post_id,format:'json'} );
post = Post.get({PostId:post_id}, function() {
post.rating = post.rating+ 1 ;
post.$save();
});
};
}).error(function(data,status,headers,config)
{} )
;})
</script>
Peharps i have mistake because in json i have a single object. But i dont really know
Besides i have such view to have a json by certain post by its id:
class UpdateModel(generics.RetrieveUpdateDestroyAPIView):
lookup_field = 'id'
queryset = BlogPost.objects.all()
serializer_class = BlogPostSerializer
permission_classes = (AllowAny,)

A quick tidy up of your script tag shows that you are only defining the function click if the http call was successful.
I would suggest moving the definition of the click method outside of the success callback.
You may also be running into a race condition that the click function has not been defined before clicking the actual button. Regardless you will want to move that function definition to where the controller is actually created.
Suggested edits (moved click definition outside of http call response):
var demoApp = angular.module('demoApp', ['ngResource']);
demoApp.controller('AllPosts', function($scope, $http, $resource) {
$scope.click = function(post_id) {
var Post = $resource('/update/:PostId ', {
PostId: post_id,
salutation: 'json'
});
post = Post.get({
PostId: post_id
}, function() {
post.rating = post.rating + 1;
post.$save();
});
};
$http.get('/blogpost/?format=json').success(function(data, status, headers, config) {
$scope.posts = data.results;
$scope.predicate = '-title';
}).error(function(data, status, headers, config) {});
})
Updates:
Injected $resource into the controller
Removed $resource from click function params

angularjs variable not showing when called before $http

In my angular app, i have a message service to display info, loading and error messages for my app. It looks like that:
module.factory('msgSvc', function(){
var current_message = '';
return {
message: function(){
return current_message;
},
setMessage: function(msg){
console.log('setting message: '+ msg);
current_message = msg;
},
clear: function(){ current_message = null; current_style = null}
}
});
and in my view i have
<span class="pull-left label label-warning" >{{ msg.message() }}</span>
I have a login controller, when the user submits the form i want to show a "logging you in..." message while an ajax login is sent. and an error message if there was an error. here's my code:
function LoginCtrl($scope, $http, msgSvc) {
[...]
$scope.login = function(creds) {
console.log(creds);
msgSvc.setMessage('Logging in...');
$http.post('http://...',creds)
.success(function(data){
console.log(data);
[...]
msgSvc.clear();
$location.path('/');
})
.error(function(data, status){
console.log(status);
msgSvc.setMessage('Wrong username or password.');
});
};
}
login() is called by the submit form, Logging in... never shows even though the function is called (it appears in the console). but the error message appears.
am i doing something wrong?
edit: the login form
<form class="form">
<input type="text" placeholder="Username" ng-model="loginCreds.username" required />
<input type="password" placeholder="Password" ng-model="loginCreds.password" required />
<button ng-click="login(loginCreds)">Login</button>
</form>

If it changes anything, there are many controllers setting messages in the service and in the actual code, the controller showing the message (where the $scope.msg variable is set) is different from the one setting the message.
function BodyCtrl($scope, msgSvc) {
$scope.msg = msgSvc;
}

There are couple problems with your implementation:
As the message is being set in a private variable, you would need use $watch for the message to be displayed;
A .factory is a singleton and therefore setMessage would have set the same message for all controllers.
The simplest solution is to pass the controller's $scope to the svcMsg:
app.factory("msgSvc", function () {
return function (scope) {
var priv_scope = scope;
this.setMessage = function (msg) {
console.log('setting message: '+ msg);
priv_scope.message = msg;
};
this.clear = function () {
priv_scope.message = "";
};
};
});
In you controller, you would then do:
var msg = new msgSvc($scope);
In case you do want to propagate the message to all controllers, use $rootScope:
app.service("msgSvc", function ($rootScope) {
var priv_scope = $rootScope;
this.setMessage = function (msg) {
console.log('setting message: '+ msg);
priv_scope.message = msg;
};
this.clear = function () {
priv_scope.message = "";
};
});
Check out this Plunker using $rootScope:
http://plnkr.co/edit/NYEABNvjrk8diNTwc3pP?p=preview
As $rootScope is really a global variable in Angular, you shouldn't abuse it. It can also be problematic if you accidentally set the $scope.message in controllers. An alternative is to use $watch to detect the change to the message:
// In your controller, do:
$scope.$watch(
function () {
return msgSvc.message;
},
function () {
$scope.message = msgSvc.message;
}
)
Here is an example using $watch:
http://plnkr.co/edit/vDV2mf?p=info

Set $scope.msg in each place you want to display the value on the view:
function LoginCtrl($scope, $http, msgSvc) {
[...]
$scope.msg = "";
$scope.login = function(creds) {
console.log(creds);
$scope.msg = msgSvc.setMessage('Logging in...');
$http.post('http://...',creds)
.success(function(data){
console.log(data);
[...]
$scope.msg = msgSvc.clear();
$location.path('/');
})
.error(function(data, status){
console.log(status);
$scope.msg = msgSvc.setMessage('Wrong username or password.');
});
};
}
I know you may be trying to avoid that but the changes in its value are not being propagated.

Add $apply to in error()
function LoginCtrl($scope, $http, msgSvc) {
[...]
$scope.login = function(creds) {
console.log(creds);
msgSvc.setMessage('Logging in...');
$scope.msg = msgSvc;
$http.post('http://...',creds)
.success(function(data){
console.log(data);
[...]
msgSvc.clear();
$location.path('/');
})
.error(function(data, status){
$scope.$apply(function() {
msgSvc.setMessage('Wrong username or password.');
});
});
};
}
