Adding hidden form field to array in Angular - angularjs

Question

I am trying to add a "hidden" field to a basic form in Angular (using Firebase as the backend). I'm having trouble figuring out how to include this field as part of the array when the form is submitted. I want to include {type: 'Basic'} as part of the array. I've looked at the other related posts on this site, but am still unsure how to apply to my particular situation.
Any suggestions on how to do this?
Javascript:
myApp.controller('NewProjectCtrl', function ($location, Projects) {
var editProject = this;
editProject.type = 'Basic'; //this is the hidden field
editProject.save = function () {
Projects.$add(editProject.project).then(function(data) {
$location.path('/');
});
};
});
HTML:
<form>
<div class="control-group form-group">
<label>Name</label>
<input type="text" name="name" ng-model="editProject.project.name">
</div>
<label>Description</label>
<textarea name="description" class="form-control" ng-model="editProject.project.description"></textarea>
<button ng-click="editProject.save()" class="btn btn-primary">Save</button>
</form>

You don't need a hidden form field, just submit your value in your controller like this:
editProject.save = function () {
editProject.project.type = 'Basic';
Projects.$add(editProject.project).then(function(data) {
$location.path('/');
});
};
All attributes of your editProject.project will be submitted, as you may notice in the developer console.
I would structure the controller a bit different.. here is an example (I am considering you are using angular-resource, where Projects returns a Resource?):
myApp.controller('NewProjectCtrl', function ($location, Projects) {
$scope.project = new Projects({type: 'Basic'});
$scope.save = function () {
$scope.project.$save().then(function(data) {
$location.path('/');
});
};
});
<form ng-submit="save()">
<div class="control-group form-group">
<label>Name</label>
<input type="text" name="name" ng-model="project.name">
</div>
<label>Description</label>
<textarea name="description" class="form-control" ng-model="project.description"></textarea>
<input type="submit" value="Save" class="btn btn-primary" />
</form>
The save function will $save the new project resource (this is an default method and will make a POST on the given resource URL).
