Best Practices: Should I use ng-switch for this? [closed]

Question

I've got this object in Angular.

$scope.columns = {
    workspace: {
        title: "Workspace",
        type: "workspace",
        activities: []
    },
    alerts: {
        title: "Alerts",
        type: "alert",
        activities: []
    },
    main: {
        title: "Main Feed",
        type: "main",
        activities: []
    }
};

And in my HTML I need to loop through it to dynamically create a series of columns in my app (think something like Trello)

Each type is a reference to a custom directive.

I'm trying to figure out the best way to place my directives.

Based on this data, is the code below an appropriate way to handle dynamically creating these?

<div ng-repeat="(key, obj) in columns">

    <div ng-switch on="obj.type">
        <workspace-feed ng-switch-when="workspace" />
        <alert-feed ng-switch-when="alert" />
        <main-feed ng-switch-when="main" />
        <filter-feed ng-switch-when="filter" />
    </div>

</div>

I'd love to be able to do something like... <{{obj.type}}-feed /> but I'm not sure if this is valid, or if there's a better way to create this.

Thoughts are much appreciated!

What you have so far looks fine.

Depending on how different your columns are, you may opt to use just one directive which dynamically loads a template instead of multiple directives. For example, take a look at ng-include:

<div ng-include="'columns/' + column.type + '.html'"></div>
