Form action with variable not valid after update to 1.2

Question

I was generating a form action in my previous version of AngularJS using this code:

<form action="{{ api }}/products/image">

However, I just updated and now that apparently is too loose.

Error while interpolating: {{ api }}/products/image Strict Contextual Escaping disallows interpolations that concatenate multiple expressions when a trusted value is required.

How do I achieve the same functionality in 1.2.4?

Answer 1

Since Angular 1.2.x, you can bind only one expression as URL.

Hence, on your controller, do the following:

$scope.actionUrl = $scope.api + '/products/image';

And in the template:

<form action="{{ actionUrl }}">

Update

As suggested by @Fourth:

<form action="{{ api + '/products/image' }}">
