Lazily initialize view model methods about laravel-view-models

[brendt]

@sebastiaanluca how about returning a closure instead?

    public function conditionalValue() : Closure
    {
        return function () {
            return 'e.g. a query that can only be run when $isAccessible is true';
        }
    }

{{ $conditionValue() }}

Hi @sebastiaanluca

It's part of the design, yes. It allows to expose all variables to the view as standalone variables, and improves debugging quite a bit.

Let's dive further into your question though, I can't see anything going wrong with the example you gave, as conditionalValue() simply returns a string. I suppose that IRL you'd have something more complex going on?

You should think of view models as representations of model/business data, they shouldn't have any side effects. Their only goal is to transform and provide data in a way that is useful to the view.

My guess is that the problem you're running into, is that your condition values have side effects? You want to solve that problem in another layer, probably using models or actions.

Feel free to share your input, but I'll close this issue as this is something we'll not change in this package.

PS: the view models using in BladeX are a separate implementation. That won't help you solve your problem, but I figured I better tell for clarity's sake.

Good alternative, thanks!
