I have a very hierarchical data structure in JSON. I also have a re-usable (Django) template that gets bound to part of that structure. So, I need to know where in that structure I am for any given template. I am almost there:
http://jsfiddle.net/trubliphone/fd64rn3y/
The missing bit is being able to pass the current ng-model to a controller.
Here is some code (but the jsfiddle above shows more detail):
my_app.js:
var myApp = angular.module('myApp', []);
myApp.factory('$global_services', ['$http', function($http) {
var data = {};
$http.get("some_url", {format: "json"}) {
/* THIS REQUEST RETURNS A BIG CHUNK OF HIERARCHICAL JSON */
.success(function (data) {
data = data;
})
});
return {
getPathFromModel: a_clever_fn_i_wrote_that_returns_a_string(),
getModelFromPath: a_clever_fn_i_wrote_that_returns_a_model()
}
}]);
myApp.controller('MyController', ['$scope', '$attrs', '$global_services', function( $scope, $attrs, $global_services ) {
if ($attrs.currentModelPath) {
/* if you passed current_model_path, get the current_model too */
$scope.current_model_path = $attrs.currentModelPath;
$scope.current_model = $global_services.getModelFromPath($scope.current_model_path);
}
else if ($attrs.currentModel) {
/* if you passed current_model, get the current_model_path too */
$scope.current_model = $attrs.currentModel;
$scope.current_model_path = $global_services.getPathFromModel($scope.current_model);
}
}]);
my_template.html:
<div ng-app="myApp">
<div ng-controller="MyController" current_model_path="data">
{{current_model.name}}:
<ul ng-repeat="child in current_model.children">
<input type="text" ng-model="child.name"/> {{ child.name }}
<!-- LOOK: HERE IS A NESTED CONTROLLER -->
<div ng-controller="MyController" current_model="child">
{{current_model.name}}:
<ul ng-repeat="child in current_model.children">
<input type="text" ng-model="child.name"/> {{ child.name }}
</ul>
</div>
</ul>
</div>
</div>
The problem is in the "div" element for the nested controller; I pass the {{child}}
ng variable as an attribute, but when the controller recieves it, it just interprets it as the JavaScript string "child". How can I pass the actual model object?
Thanks.

<div ng-controller="MyController" ng-init="data = child">
this will add an object to the inner scope named data.
