问题
I am using ngResource in a factory to fetch data from a REST API URL, and then do some basic processing on the retrieved data. This works fine (verified using console.log()). I injected the dependencies properly in my root module and in the main controller, and set a $scope variable equal to this retrieved data.
In HTML, I put {{variableName}} inside the desired tag.
However, it doesn't get populated.
What am I missing? Do I need to add $watch or something else in order for this to work?
PS -
var dataResource = $resource("http://<URL>");
$scope.trialData = dataResource.get();
This trialData populates values from the same URL just fine when I add this directly to the controller.
回答1:
Resources use asynchronous request. You have to wait for their promise to be resolved like this :
dataResource.get().$promise.then(function(object){
$scope.trialData = object;// or maybe object.data
});
