Can you override specific templates in AngularUI Bootstrap?
I'm curious if there's a way to override single, specific templates from the ui-bootstrap-tpls file. The vast majority of the default templates fit my needs, but there's a couple specific ones I'd like to replace without going through the whole process of grabbing all the default templates and getting them wired up to the non-tpls version.
Solution 1:
Yes, directives from http://angular-ui.github.io/bootstrap are highly customizable and it is easy to override one of the templates (and still rely on the default ones for other directives).
It is enough to feed $templateCache, either feeding it directly (as done in the ui-bootstrap-tpls file) or - probably simpler - override a template using the <script> directive (doc).
A contrived example where I'm changing alert's template to swap x for Close is shown below:
<!doctype html>
<html ng-app="plunker">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
<script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.4.0.js"></script>
<script src="example.js"></script>
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet">
<script id="template/alert/alert.html" type="text/ng-template">
<div class='alert' ng-class='type && "alert-" + type'>
<button ng-show='closeable' type='button' class='close' ng-click='close()'>Close</button>
<div ng-transclude></div>
</div>
</script>
</head>
<body>
<div ng-controller="AlertDemoCtrl">
<alert ng-repeat="alert in alerts" type="alert.type" close="closeAlert($index)">
{{alert.msg}}
</alert>
<button class='btn' ng-click="addAlert()">Add Alert</button>
</div>
</body>
</html>

Solution 2:
Using $provide.decorator
Using $provide to decorate the directive avoids the need to directly mess around with $templateCache.
Instead, create your external template html as you might normally, with whatever name you please, and then override the directive's templateUrl to point at it.
angular.module('plunker', ['ui.bootstrap'])
.config(['$provide', Decorate]);
function Decorate($provide) {
$provide.decorator('alertDirective', function($delegate) {
var directive = $delegate[0];
directive.templateUrl = "alertOverride.tpl.html";
return $delegate;
});
}

(Note that you must append the 'Directive' suffix to the directive name you intend to decorate. Above, we're decorating UI Bootstrap's alert directive, so we use the name alertDirective.)
As you may often want to do more than just override the templateUrl, this provides a good starting point from which to further extend the directive, for example by overriding/wrapping the link or compile function (for example).
