cc'ing to dev list, original thread here:
http://lists.osgeo.org/pipermail/qgis-user/2014-December/030180.html
Me neither, best to bring this to the dev list then, to ask which this
extension is.
And IF we want a FILE parameter work for postgis we could come up with a
design for that file param and do a feature request to get this implemented?
For example, as this works:
l = iface.addVectorLayer('dbname=bag host=localhost port=5432 user=geo
password=xxx sslmode=disable key=gid estimatedmetadata=true srid=28992
type=MULTIPOLYGON table="bag8mrt2014"."provincie" (geovlak) sql=',
"test", "postgres")
this is the actual uri:
'dbname=bag host=localhost port=5432 user=geo
password=xxx sslmode=disable key=gid estimatedmetadata=true srid=28992
type=MULTIPOLYGON table="bag8mrt2014"."provincie" (geovlak) sql='
so maybe prepend that with the provider part:
postgres:'dbname=bag host=localhost port=5432 user=geo
password=xxx sslmode=disable key=gid estimatedmetadata=true srid=28992
type=MULTIPOLYGON table="bag8mrt2014"."provincie" (geovlak) sql='
and add a --uri option to QGIS?
qgis --uri postgres:'dbname=bag host=localhost port=5432 user=geo
password=xxx sslmode=disable key=gid estimatedmetadata=true srid=28992
type=MULTIPOLYGON table="bag8mrt2014"."provincie" (geovlak) sql='
or something like that?

Re: [Qgis-developer] Python Oracle getFeatures non working on non-geometric tables
Hello,
I've been further this morning... You just need to build a
QgsFeatureRequest which grabs the NoGeometry features.
layer =
QgsMapLayerRegistry.instance().mapLayersByName('MY_ATTRIBUTE_TABLE')[0]
for f in
layer.getFeatures(QgsFeatureRequest().setFlags(QgsFeatureRequest.NoGeometry)):
print f
This behavior seems to be specific to Oracle NoGeometry QgsVectorLayers.
I have made tests under PostGIS and Spatialite and you can use the
getFeatures() method without specifying a QgsFeatureRequest to grab all
the features of the layer.
Should I file a bug report on Oracle provider ?
Best regards,
Le 2014-12-09 17:47, mederic.ribreux a écrit :
Hello,
I am trying to iterate over a non geographic table under PyQGis. The
table is stored in an Oracle database and I use QGis Api to get the
data (table is opened in a QGis project with Oracle provider). I have
added primary key constraint to this table but I am not able to
iterate through its features with the getFeatures() method. The
following snippet always returns nothing:
layer =
QgsMapLayerRegistry.instance().mapLayersByName('MY_ATTRIBUTE_TABLE')[0]
for f in layer.getFeatures():
print f
I have tried with a geographic layer and there is no problem on this
side because the above snippets prints a line for every feature in the
table. I have also tried with opening the geographic table without
geometry (geometry is "No Geometry"). In this configuration, I am not
able to get access to the features...
I have tried to reproduce this on a PostgreSQL/PostGIS server and
there is no bug: I am able to iterate over a non-geographic layer
(even a geographic layer declared as non-geographic).
Is this a problem with the Oracle provider or just me having forgotten
something in the table ?
Best regards

The tests run on a headless server with xvfb. So I assume that doing anything with xvfb-run python yourapp.py and no messing with display should work perfectly as well.

Re: [Qgis-developer] Error : cannot connect to X server on Ubuntu
I have never run a processing model standalone, so I cannot help there. I don't know how closely tied this is to GUI related things. It may or may not work without X. But if you have to create a QgsApplication which is a QApplication I am pretty sure that you need to have some kind of X running. So it would be a matter of getting processing to run without QgsApplication. How does hadoop-mapreduce work? Is it not possible to spawn one separate xvfb-run process per map?
