Serving geoJson with custom coordinates

[ElijasZ]

Hello, sorry if this is a noob question, but i didn't find the answer in previous issues.
So i need to return geoJson which is build from scratch (coordinates and properties). So far I've found only examples with with custom properties, and coordinates straight from models. Ts there a way to include coordinates as well? (I am trying to return feature collection, which consists of polygons).

Where do those features come from?

You can make a view which return the geojson you want by building it yourself.
