Checking inputs of form in django before submit

I am using Django and try to submit a form.
I have a "call-us" form and there is 3 fields.
I want to make this, If one of the fields is empty, and the user clicked on Submit button, don't send the info to View and warm the user that they must complete the required fields.
here is my form:
<form role="form" action="{% url "landingpages:callusthanks" %}" method="post" style="max-width: 500px;margin: 0 auto;margin-top: 30px;">
{% csrf_token %}
<div class="form-group">
<div class="input-group">
<div class="input-group-addon"><i class="fa fa-user"></i></div>
<input type="text" name="name" class="form-control" id="name" placeholder="Name">
</div>
</div>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon"><i class="fa fa-at"></i></div>
<input type="text" name="email" id="email" class="form-control" placeholder="Email">
</div>
</div>
<div class="form-group">
<div class="input-group">
<div class="input-group-addon"><i class="fa fa-envelope-o"></i></div>
<textarea name="message" class="form-control" id="message" placeholder="Message"></textarea>
</div>
</div>
<div class="form-group row">
<div class="col-xs-6 col-xs-offset-6">
<button type="submit" class="form-control">Send</button>
</div>
</div>
</form>

As one option you can use jQuery validation and set the required fields like so:
$(document).ready(function(){
$("#your_form_id").validate({
rules :{
your_field : {
required : true
}
.....
},
messages :{
your_field : {
required : 'your_field is required'
}
.....
}
});
});
Edit: Just saw you said not to send to view. So, ignore this but I'll leave it for future reference on the off chance that it's useful.
Preferably, you could turn this into a form import it from forms.py and then send it to your view. You could then just set which fields are required.

Use a factory to store your data and then retrieve the same.

angularjs - form with ng-repeat inside it error on submitting

I have the following form : two text inputs then an ng-repeat with a text and radio inside.
<form class="form-horizontal" id="myForm" name="myForm">
<div class="form-group">
<label for="name" class="col-sm-2 control-label">Company Name</label>
<div class="col-sm-10">
<input type="text" name="cname" ng-model="company.name" class="form-control" required></input>
</div>
</div>
<div class="form-group">
<label for="category" class="col-sm-2 control-label">HQ</label>
<div class="col-sm-10">
<select ng-model="company.hq" ng-options="hq as hq.name for hq in hqs" required>
<option></option>
</select>
</div>
</div>
<div class="form-group" ng-repeat="item in getR(4) track by $index">
<label for="name" class="col-sm-2 control-label">Top pick {{$index+1}}</label>
<div class="col-sm-10">
<input type="text" name="quizsize" ng-model="company.product[$index]" class="form-control" required></input>
<label><input type="radio" name="test" ng-model="company.radioValue" value="{{$index+1}}"/> Choose</label>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" value="submit" class="btn btn-primary" ng-click="addCompany(company)"></button>
<button type="btn" value="cancel" class="btn btn-danger" ng-click="cancelBtn()">Cancel</button>
</div>
</div>
</form>
addCompany method from the controller :
$scope.addCompany = function(company)
{
console.log(company.radioValue);
$http.post('http://localhost/api/index.php/Test/companies', company)
.success(function(data)
{
$scope.companies.push(data[0]);
})
.error(function(err)
{
})
};
And the method to for the inputs ng-repeat:
$scope.getR = function(n)
{
return Array(n);
}
When I submit it:
If I start by adding company name/hq then all is good, but
If I start by first clicking on a radio button then when I send the form I get an undefined radioValue error.

use ng-value instead of value to be sure the model is ready to be bound to
<input type="radio" ng-value="($index + 1)" ng-model="company.radioValue">

Form gets submitted even if the required fields are left empty in angular JS

I am newbie to angular JS and i have created a form which is
HTML
<div data-ng-controller="ReservationController"
<form class="form-horizontal" role="form">
<div class="form-group">
<div class="col-sm-10">
<label>Guest Name</label>
<input type="text" class="form-control" placeholder="" ng-model="res_guest_name" required>
</div>
</div>
<div class="form-group">
<div class="col-sm-10">
<label>Phone</label>
<input type="phone" class="form-control" ng-model="res_member_phone">
</div>
</div>
<div class="form-group">
<div class="col-sm-10">
<label>FAX</label>
<input type="phone" class="form-control" ng-model="res_member_fax">
</div>
</div>
<div class="form-group">
<div class="col-sm-10">
<label>Email</label>
<input type="email" class="form-control" ng-model="res_member_email" required>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-8 col-sm-10">
<button type="submit" class="btn btn-success" ng-click="res_save()">Save Changes</button>
</div>
</div>
</form>
</div>
CONTROLLER
function ReservationController($scope, $http, $cookieStore,$location,$filter) {
$scope.res_save = function()
{
var save_res ="https://pbg.com/save_form.html?contactid="+conId+"&token="+token+"&id="+$scope.resId+"&page=edit&guest_name="+$scope.res_guest_name+"&phone="+$scope.res_member_phone+"&fax="+$scope.res_member_fax+"&email="+$scope.res_member_email;
$http.get(save_res).success(function(response) {
alert('success');
});
}
}
My form gets submitted even after the required fields are left empty. it shows the error, then it gets submitted.

Obviously it will submit the form you didn't handled the submission of form.You just managed the errors :-)
Use ng-disabled="myForm.$invalid"
where myForm is the name field on form
<form class="form-horizontal" name="myForm" role="form">
<button type="submit" class="btn btn-success" ng-disable="myForm.$invalid" ng-click="res_save()">Save Changes</button>
If you don't want the button to be disable till then you can use
<button type="submit" class="btn btn-success" ng-click="res_save(myForm.$valid)">Save Changes</button>
And in controller
$scope.res_save = function(valid)
{
if(valid){
var save_res ="https://pbg.com/save_form.html?contactid="+conId+"&token="+token+"&id="+$scope.resId+"&page=edit&guest_name="+$scope.res_guest_name+"&phone="+$scope.res_member_phone+"&fax="+$scope.res_member_fax+"&email="+$scope.res_member_email;
$http.get(save_res).success(function(response) {
alert('success');
});
}
}

You are not checking for Form valid state before saving it , don't expect angular to magically stop saving when form is invalid.

You should look into the documentation for ng-submit. If you move the res_save function into an ng-submit on the form (and removed the ng-click on the submit input) it will validate against required fields, prevent execution of the function until they are valid.

Reset form after submission in AngularJS

I'm having trouble resetting form fields after submitting in AngularJS (v1.1.3). Here's a snippet of what I'm trying to do:
HTML
<form name="addMemberForm">
<input name="name" type="text" placeholder="Jon Doe" ng-model="member.name" required/></td>
<a class="btn btn-primary" ng-click="createMember(member)" ng-disabled="addMemberForm.$invalid"><i class="icon-plus"></i></a>
</form>
JS
$scope.createMember = function(member) {
var membersService = new Members(member);
membersService.$create(function(member) {
$scope.members.push(member);
$scope.addMemberForm.reset(); //TypeError: Object #<FormController> has no method 'reset'
});
};
Is there another way to reset form elements?

Figured it out thanks to #tschiela's comment. I had to do this:
$scope.createMember = function(member) {
var membersService = new Members(member);
membersService.$create(function(member) {
$scope.members.push(member);
$scope.member = '';
});
};

Just Take default value of the form .
HTML form
<form novalidate id="paperForm" class="form-horizontal" name="formPaper">
<div class="form-group">
<label class="col-sm-3 control-label" for="name">
Name
</label>
<div class="col-sm-8">
<input type="text" id="name" placeholder="Please Enter Name" class="form-control" ng-model="paper.name" ng-name="name" required>
</div>
<label class="col-sm-3 control-label" for="name">
Department
</label>
<div class="col-sm-8">
<input type="text" id="department" placeholder="Please Enter Department" class="form-control" ng-model="paper.department" ng-name="department" required>
</div>
</div>
<button type="button" class="btn btn-default" ng-click="reset(paper)">Reset</button>
</form>
set reset code inside controller
var deafualtForm = {
name : '',
department : ''
}
$scope.reset= function(paper) {
$scope.paper = angular.copy(deafualtForm);
}
