[GeoNode-devel] Update the BBOX of an existing layer

Yiasou Tom,

Thanks for your answer. I have also found out that the signal you mentioned
does this. Instead of calling  layer.save(), I execute the signal directly
in my application as:

from geonode.catalogue.models import catalogue_post_save
from geonode.layers.models import Layer
layer = _resolve_layer(
instance = layer
catalogue_post_save(instance, Layer)

In my workflow, I have a layer with a specific BBOX. Then I add a new
feature (e.g. a point), which is outside this BBOX. To add the point I send
a WFS INSERT POST request. The point is added successfully and its visible
in Geoserver (layer preview). I also send another request to "recalculate"
the BBOX displayed in the layer's page in Geoserver.

So my question is how to update the BBOX coords stored in the
base_resourcebase table with the BBOX coords, which were recalculated in

Executing the above signal it doesn't get the BBOX values from the
geoserver but the ones from base_resourcebase so basically nothing is

I guess what I need to do is when I recalculate the BBOX for the layer in
Geoserver, to pass these new coordinates to the base_resourcebase. But I
can not figure out if there is a signal/function for this.
