Can directive scopes (such as obj.prop) be linked together in a chain?

Here is the directive code I am currently using:


  template: '<form novalidate class="form-inline" ng-submit="submit($event, building)">' +
      '<div class="form-group">' +
        '<label class="form-control-static">{{label}}</label>' +
      '</div>' +
      '<div class="form-group">' +
        '<input name="input" class="form-control" type="text" ng-model="model" />' +
      '</div>' +
      '<input class="btn btn-default" type="submit" value="Submit" />' +
      '</form>',
  scope: {
    label: "@",
    building: "=",
    model: "=",
    //type: "=",
  },

Currently, in my HTML, I have to use the following code:

<building-field label="name" building="building" model="building.name"></building-field>

I would like to simplify it by only needing to add the building and the label (and then combine them inside the directive using ng-model="building.name"):

<building-field label="name" building="building"></building-field>

The challenge I am facing is that I'm unsure of how to pass two directive scopes and link them as obj.prop. How can this be achieved?

Answer №1

There is no need for any special action, as obj.prop is fully supported. When creating your template:

<input name="input" class="form-control" type="text" ng-model="building[label]" />

One thing to keep in mind is that you are connecting label with an interpolation method (using @). This implies that the value in scope.label will always be "name". If you wish to pass the actual value of name, then you should use double curly brackets:

<building-field label="{{name}}" building="building"></building-field>
