You don't really want to generally be converting it to JSON while in the view, and You do not actually need to transform it from the controller, as neither of such locations make sense. Regrettably, you happen to be caught with this case.

ViewModel only incorporates the Houses, so that you can state that ViewModel can contain only Individuals Qualities from more than one Models that we need to Exhibit or use in a single view webpage.

Yet again these are populated Together with the demanded information (commonly the info required for a specific display screen and will be an aggregation of information from many resources) and despatched towards the consumer.

The real world, nonetheless, is rarely as easy. Generally, Views are elaborate and incorporate artefacts from more than one area entity. And maybe merely a subset of any entity's properties.
