Class OwnerFilter

Filter entities to show only these belonging to a specific user.

The OwnerFilter DataSource is part of the Standard EAV Data Sources. It will only let items pass through, which a specific user (often the current one) has created initially.

You will typically use the OwnerFilter in scenarios where users create their own data, and should only see/edit items which they own (usually in combination with security settings, which only allow the owner to modify their own items).

How to use with the VisualQuery

When using the VisualQuery you can just drag it into your query. You must then edit the settings once - and usually you will use the recommended prefilled-form. But you can also do something different. This is what it usually looks like:

The above example shows:

  1. a content-type filter limiting the items to type Company
  2. an owner-filter which receives 5 items, but only lets 3 pass, because the Test Settings have a demo-value of the user who only created 3 of the 5 items.

Programming With The OwnerFilter DataSource

We recommend to use the VisualQuery where possible, as it's easier to understand and is identical for C# and JavaScript. It's also better because it separates data-retrieval from visualization.

Remarks

Technically many things could just identify the app they belong to, and let the system look up the zone. But this would be inefficient, so for optimization, many items identify themselves with both the app and zone Ids
