Access ng-pattern in error message

I have an ng-repeat for a list of attributes and want to show error messages for each input. For a pattern error I also want to show the specific regex it has to match.
Can I access an input's pattern somehow? I know I could add an attribute containing the regex but I would like to know if there is an angular way somehow.
(This is an oversimplified example, the regexes can be different for different attributes)
<form name="form">
<div data-ng-repeat="(attributeName, attributeMetaData) in configuration.metaData">
<input data-ng-model="configuration[attributeName]" type="text" name="{{attributeName}}" data-ng-pattern="/^[0-9][0-9]:[0-9][0-9]$/">
<span data-ng-show="form[attributeName].$error.pattern && form[attributeName].$dirty">
Please check your input format [pattern should go here]
</span>
</div>
</form>

Based on your restriction that the model cannot be changed, I guess your best bet is to have a separate model containing just regexes

Why I can't access a form object inside a ngInclude on angularJS?

I have a screen built with a several stacks of ng-includes. The last one, in special, I build the screen based on user configuration.
Sometimes, I have to show a Form in one of this included templates. And when my user click on save button, I have to validate if all fields in the form are valid.
In the meantime, when a try to access form object, to check for $valid, my form is undefined.
After a day fighting against it, I've discovered that ng-include process is not accepting my form object to be created.
I've created this plunker to see if it's really happening on a simple project, making a working form and not working one:
http://plnkr.co/edit/4oMZYLgaYHJPoSZdSctI?p=preview
Basically, created a form, like this, with demanded angular attributes:
<form name="sampleForm">
<input type="text" name="aws" required ng-model="myValue">
<br/>myValue: "{{ myValue }}"
<br/>
<input type="text" name="aws" required ng-model="myValue">
<br/>myValue: "{{ myValue }}"
</form>
And trying to access form object like this:
$scope.sampleForm.aws.$valid
And the result is:
$scope.sampleForm === undefined
Someone know how to solve this problem?

Since ng-include creates a new scope, $scope.sampleForm will be undefined from within the included page.
The solution should be getting the ng-controller="formController" declaration inside of the included HTML page itself, which I think is also a better design, since I can't see a scenario where it's not "controlling" the form.
The other non-included form obviously works as you might expect.

how to get value ng-model in html to javascript

Probably silly question, but I have my html form with simple input and password:
<li>
<input type="text" placeholder="Username" ng-model="user.username" />
<a class="iconani usera"></a>
</li>
<li>
<input type="password" placeholder="Password" ng-model="user.password" />
<a class="iconani locka"></a>
</li>
and i want to get value from ng-model to java script
query.equalTo("user", document.getElementById('value from ng-model'));
I use this from parse.com
Can you help me?

In AngularJS, you don't need (and want) to touch your DOM at all to get the data. ng-model directive creates an automated two-way binding between your <input> and your $scope.user variable's properties.
login($scope.user.username, $scope.user.password, ...);
You don't need to touch the form itself at all.

hon2a's answer is the right one ;-) I can try to explain it a bit differently as I also just recently started using angular. A good and simple intro to angular concepts of ng-model and controllers is given at http://www.w3schools.com/angular/angular_intro.asp.
So, all your javascript should be executing in Angular Controllers. In the corresponding controller (i.e. javascript code) the data from HTML form is bound using that angular directive "ng-model" and nothing else. You have your HTML part just fine, assuming you have the angular stuff somewhere linked properly (I would strongly recommend using Yeoman Angular generator to handle that...). At least there should be something like this:
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
</head>
<body>
<div ng-app="yourApp" ng-controller="yourController">
<!-- your app part goes here -->
</div>
And then the in the angular controller you actually have that data at hand automatically without doing anything else than just having a constructor/initialiser for it:
angular.module('yourApp').controller('yourController', function ($scope) {
$scope.user = {'username': '', 'userpassword': ''};
// And rest of your stuff goes here...
// In your functions, just use $scope.user.username and $scope.user.userpassword.
}
Hope this helps...

auto update the html dom for all the users whenever there's change

I am sorry for asking such a noob question. But I saw a video very long time ago and I think it was a framework based on jquery, where if a user makes some CRUD changes to an object, the object's properties are auto updated not only for 1 user, but on all the other users browser. I am trying to find it but I am all lost! I would really really appreciate if you could help me out. Thank you!

Lets say you have a html form that looks like this
<form>
<input type="text" name="firstName" value="Jackson" />
<input type="text" name="lastName" value="Rivera" />
<textarea name="lifestory">
When i was 2yo, spot died...
</textarea>
</form>
simply add an OnChange event on every element you want to dynamicly change:
<form>
<input .. .. onchange="shareValueWithOthers(this.name, this.value)"/>
<input .. .. onchange="shareValueWithOthers(this.name, this.value)"/>
<textarea onchange="shareValueWithOthers(this.name, this.innerHTML)">
When i was 2yo, spot died...
</textarea>
</form>
Notice that a change of the elements value (or in the case of the textarea - it's contents) causes the function shareValueWithOthers(this.name, this.value) starts to run. this.name is the variable for the name, this.value is the variable for the value, this.innerHTML is the variable for the contents.
Now you have to write a Javascript function so you can send the changes to the server. Look into AJAX. Make a function that sends a POST request to your PHP script.
Your PHP script should save all the values either in a database, or in JSON-format in a file on the server. JSON is the easiest. Look into JSON PHP PARSER.
Last but not least. If you do the right thing, and make sure that every new value that a user enters gets updated in your json file by your PHP script. You can make the last step. which is to make a javascript function that retrieves the JSON file. JSON stand for JavaScript Object Notation, so your javascript can use this right away.
What you will do next, is to change all the values in your DOM that look different from the values in your retrieved JSON object.

Mustache.js render technique

i am trying to use mustache.js to render some JSON in the browser.
What i want to do is:
<li>
<span class="label">Location: </span>
{{#locations}}
{{.}}<span class="social-small-size "></span>
{{/locations}}
</li>
The locations is a js array
[["Pendéli, Attiki, Greece", "facebook"], ["Greece", "linkedin"]]
Initially i tried to use {{%IMPLICIT-ITERATOR iterator=loc}} in my attempt to split the data in the view. So i the actual rendering code was
{{loc[0]}}<span class="social-small-size {{loc[1}}"></span>
But that did n t work altough the loop worked and i got 2 spans but without any content. I think the PRAGMA is what I need but I didn 't figure it out. Any hints ? :)

The answer is quite simple, do not use arrays in array. You should uses hashes.
The above code should work as
{{#locations}}
{{value}} <span class='social-small-size {{network}}'></span>
{{/locations}}
