#2571 closed bug (invalid)

Path to GRASS vector map loses "vector/" in path string

Reported by: neteler Owned by: rugginoso
Priority: major: does not work as expected Milestone: Version 1.5.0
Component: GRASS Version: Trunk
Keywords: vector Cc: rblazek
Must Fix for Release: Yes Platform: All
Platform Version: Awaiting user input: no

Description 

To access Quantum GIS environment from this console
use qgis.utils.iface object (instance of QgisInterface class).

>>> iface=qgis.utils.iface
>>> map=iface.mapCanvas()
>>> print map.layer(0).source()
/home/neteler/grassdata/patUTM32/mymapset/box/1_polygon
>>>

the correct path to a GRASS vector layer would be including "vector/" in the string: 

/home/neteler/grassdata/patUTM32/mymapset/vector/box/1_polygon

Note: for raster layers it is ok: 

>>> print map.layer(1).source()
/home/neteler/grassdata/patUTM32/neteler/cellhd/elevation

The omission of "vector/" in the string leads to troubles in ogr2ogr called by QGIS plugins.

Resolution: → invalid
Status: new → closed

layer.source() is internal data provider representation of data location. For GRASS vector provider it is GISBASE/LOCATION/MAPSET/MAP/LAYER_TYPE.

Expecting that layer.source should be a valid OGR DSN is just misunderstanding.

Warning: please don't try to change that format, it would break all old project files.
