[GeoNode-devel] Programmatically create layers and maps from own Django App

Wed Sep 11 08:59:37 PDT 2019

Hi Steffen,

sorry. Did not test it before sending. But darkly remember I did something like this with 2.4.
Anyways from a quick look the problem is that your map has wrong
zoom
center-x
center-y

further your added layer is missing:
OWS URL
Layer params
Source params

You can test it by manually creating a map with same layer and afterwards by django shell.
As soon as you fix those values in django admin it works.

Unfortuanately I'm facing a strict deadline and cannot say when there will be time for further tests. 
But would suggest that you start by having a look at the maps model.

Cheers,

Toni
