Accessing single json value via Angular?

Question

my API returns this value:

{"id":1,"name":"Test"}

In Angular I did this call to retrieve that value:

$scope.supplier = Suppliers.query({supplierId: $routeParams.id});

But now in my template I do this:

{{supplier.name}}

Even {{ supplier }} does not give me anything.

but this is empty. Why is this the case?

Thanks!

share your service or more code that you have in controller, in your case it looks like a promise is not getting resolved, so that could be your problem. — pegla

The query function returns a callback, try this:

Suppliers.query({supplierId: $routeParams.id}, function(suppliers) => {
    $scope.supplier = suppliers[0];
});

Since query returns a list you need to take only the first from the list.

I had to do it a bit differently: Suppliers.query({supplierId: $routeParams.id}, function(response) { $scope.supplier = response; }); But in this case {{ supplier }} looks like this in the frontend: [{"id":1,"name":"Test"}] - so we have an array with an object, but supplier.name or supplier.0.name does not result in anything :( Any idea? I do not see it :(

Ah I can use {{supplier[0].name}}

var supplier = Suppliers.query({supplierId: $routeParams.id},{_id:0,name:1});

$scope.supplier=supplier[0].name;
