  • Status changed from Open to Closed
  • Resolution set to invalid

The user must specify the geometry column name.

#2 Updated by Paolo Cavallini about 7 years ago

The default should work, and the user should be warned what to type.
As it is, the tool is unusable by most.

there is already a feature request for improvements. As it is it works, just select the proper geometry column name (that by the way is ok by default for most of formats, as shapefiles). If you want to geoprocess postgis layers within postgis with processing there is a proper plugin for that.

#4 Updated by Paolo Cavallini about 7 years ago

Probably adding a short help and a note to the param would help.
Thanks.

#5 Updated by Paolo Cavallini about 7 years ago

Anyway, IMHO this is still a bug: every command should work with the default values.

feel free to submit the patch to automatically get the geom column name of inputs (not yet implemented in Processing afaik).

#10 Updated by Paolo Cavallini about 7 years ago

As said, this requires a patch, as for the user it does not work: what is the purpose of closing it?

as it is it works just fine, what you propose is an improvement.

#12 Updated by Paolo Cavallini about 7 years ago

Sorry to insist: it works for many data sources, not for PostGIS, without user warnings.

the users just need to change "geometry" in "geom" or whataver is the geometry column name.
The parameter title is very clear

Geometry column name ("geometry" for shapefiles, maybe different for other formats)

is that not clear enough?!

#14 Updated by Paolo Cavallini about 7 years ago

You are right, thanks. Perhaps in the help we could add other common names for other formats (geom for PostGIS, other?).

there is a plan to tentatively add something to get automatically the geom column name.
