As mentioned in multiple issues (#160, #20),
ember-can
currently doesn't support async abilities. This seems to be an issue for a lot of its users as it is a real use-case that permissions are evaluated with e.g. a call to an API.This PR would support async abilities without changing the current API at all. The only thing required for it to work in templates would be
ember-promise-helpers
to handle the promises in the templates.This solution is currently running in one of my projects and works pretty good. Please let me know if you are interested in this. If this is a viable solution, we could also look into changing the template helpers so they can handle the promises itself in order to drop the necessary dependency.
