GEODJANGO Problem/Question

2022-05-10 Thread Steve Watts 
I am running a LayerMapping on a set of ShapeFiles acquired from a County 
GIS Department. I've done a quite a bit of this, and this is the first time 
I"ve seen such an issue. As LayerMapping is proceeding through the file 
saving model instances, it encounters one that it can't handle:

"GDAL_ERROR 1: b'Geometry of polygon of fid 5572 cannot be translated to 
Simple Geometry. All polygons will be contained in a multipolygon.'"
"GDAL_ERROR 1: b'organizePolygons() received an unexpected geometry. 
 Either a polygon with interior rings, or a polygon with less than 4 
points, or a non-Polygon geometry.  Return arguments as a collection.'"
"GEOS_ERROR: IllegalArgumentException: Invalid number of points in 
LinearRing found 3 - must be 0 or >= 4"
"Failed to save the feature (id: 5572) into the model with the keyword 
arguments:"
And the final Exception:
"GEOSException: Error encountered checking Geometry returned from GEOS C 
function "GEOSWKTReader_read_r"."

The best description of the issue I can find is 
https://github.com/r-spatial/sf/issues/1589. In this help thread, and a 
related one, they talk about a utility called "MakeValid" to resolve this 
LinearRing issue.

It appears I need to either add a point to any of these "LinearRing" 
instances, or somehow otherwise fix these items.

I'm not sure that sending the ShapeFiles back to the County to "fix" would 
be productive.

Does anyone have anything to contribute as far as how I might best move 
forward with this set of ShapeFiles?

Is there another forum where I should be addressing this issue? Need more 
information?

Thanks!

Steve Watts

yes. I went through the documentation but did not work on what I wanted to
achieve. I am totally lost

Django Admin external script before save/delete

2022-05-10 Thread Thiago Luiz Parolin 
Hello everyone,
I'm trying to run a script before saving and deleting objects in db
using django admin.
If the script fails, the action (save or delete) needs to be aborted
and we need to inform the user with a message.

In the django docs:

"...When overriding ModelAdmin.save_model()
andModelAdmin.delete_model(), your code should save/delete the object.
They are not for veto purposes, but allow you to perform extra operations..."

So using modelform I can make this work for save, but how can I make
it for delete (or delete_queryset) too?

Thanks!

Re: Images

You change the names of the pictures in the separate folder then copy them
in a static folder then change the picture file names in the template
folder then refresh then see pictures are new ones or not

The link literally starts with "This document explains the usage of 
Django’s authentication system in its default configuration" so it seems 
like an obvious place to look in order to figure out "how to use them".


Have you tried reading the documentation?

Kind regards,
