Mapping Angular input fields to Go struct with array using Restangular

Question

I have a Go struct:

type Foo struct {
    Name   string   `json:"fooName"`
    Things []string `json:"things"`
}

I have an Angular html page:

<input type="text" name="fooName" ng-model="foo.fooName"/>

<div ng-repeat="thing in things">
    <input ng-model="foo.things" type="text" name="thing-{{$index}}"/>
</div>

In the Angular controller I have:

$scope.save= function(){
    Restangular
        .all('foos/new')
        .post($scope.foo).then(function(foo) {
            $location.path('/admin/fooManagement');
        });
};

The rest service call calls:

func CreateFoo(w http.ResponseWriter, r *http.Request) {
    defer r.Body.Close()
    var f Foo
    dec := json.NewDecoder(r.Body)
    dec.Decode(&f)
    log.Println("**** CreateFoo.... ")
    log.Println(&d)
}

Foo's name comes through, but I cannot get the "Things" array populated with the input values. I'm trying to figure out how to get the post service call to populate the array.

Answer 1

I am not experienced in AngularJS, but I do know Javascript and Go pretty well:

<div ng-repeat="thing in things">
    <input type="text" ng-value="foo.things[$index]" name="thing[{{$index}}]"/>
</div>

Assuming that foo.things and things are not the same array and that both are in scope.

With the ng-value directive, we're binding this input's value to foo.things' element at index $index.

And the name attribute follows Restangular's (undocumented) array-notation.
