Management commands for uploading layers need to be updated

[NyakudyaA]

Problem

I have a layer published in geonode and wanted to change the style for the layer. So I uploaded a new layer style and the file to the server. I ran management commands python manage.py uploadlayers -o folder_path The - o option allows file overwrite. I expect the layer style to be updated.

Observation

• It seems the overwrite option does not actually do its job.
• Old layer references are kept

Solution

• Ensure that when a user uses the overwrite function for uploading an existing layer all references of the layer are actually rewritten.
• Overwrite function should trigger a delete of qgis project, tile cache and generate new ones

This problem is also related to #149

This will be quite challenging at first thought, but I will give it a try. The easiest way is to just add extra lines for QGIS Server and not thinking about abstractions at the moment.

AFAIK, we rename the layer with a random string at the end if one layer is already existing with the same name, isn't it ?

[lucernae]

importlayers management command from geonode will replace the existing layer, so it will have the same name, at least that's what I saw from day to day observations.

I checked it again and Geonode gave a random string. My memories is playing tricks on me!

[Gustry]

I just checked my qgis_layer directory, and I have a random string if the layer is there many times. So I don't know we can track down for the original layer name.

@NyakudyaA I addressed these requests:

• Ensure that when a user uses the overwrite function for uploading an existing layer all references of the layer are actually rewritten.
• Overwrite function should trigger a delete of qgis project, tile cache and generate new ones

However it still generates random string at the end

please test again @NyakudyaA

This seems to be partially working. All the tiles are removed and the new style propagates but the thumbnail looks like it isn't being regenerated again.
