[QGIS-Developer] Processing modeler way to get settings

[Luigi Pirelli]

Hi

I'm looking for a way to get qgis settings values using teh graphical
modeler, e.g. without using any python, or custom expression function.

I'm preparing a processing provider that just add some models (in the same
way as done by resource sharing plugin) and some provider specific
settings. But I can't find the way I can read this settings other that
creating a custom script.

Am I missing something?

is there a way?

Luigi Pirelli

p.s. I suppose is simple to add a new expression operator in core to add
the feature to read settings, but my target is LTR, so any new feature
can't be used.
p.p.s. or just add provider settings as new expression scope?

[QGIS-Developer] Processing Modeler

[Frank Miller]

Hi,
I am very new in this group and have a question you may be very familiar
with. I am trying to add 'Clip raster by mask layer' tool to processing
modeler and download DEM data from an online resource but so far there is
no luck.
Does GDAL works in Processing Modeler? If yes what is my problem?

I tried to use 'Download' tool but it does not have clipping option and
downloads the entire data.
The main question is 'how can I download a part of DEM from an online map'.

Regards,
Frank

[QGIS-Developer] Processing modeler inputs and PostgreSQL execute SQL

[Alexandre Busquets]

Is it possible to add "Input" parameters to "PostgreSQL execute SQL" sql
query, like [buffer] {buffer}?

Re: [QGIS-Developer] Processing modeler GUI unusable in KDE / Plasma

[Andreas Neumann]

Hi Etienne and Nyall, 

Indeed - removing the file "qgis_customwidgets.py" from
/usr/lib/python3/dist-packages/PyQt5/uic/widget-plugins brought the
Processing modeler back to normal! 

Cool! 

So now we at least do know that this is the culprit. 

Thanks,
Andreas

Re: [QGIS-Developer] Processing modeler GUI unusable in KDE / Plasma

[Etienne Trimaille]

I got the problem too for many months even if it was disabled in the cmake.
I needed to remove the qgis_customwidgets.py in the site-package folder of
Python

Maybe a `locate qgis_customwidgets.py` might help?

Hi Mathieu,

Thanks for your efforts! I just tested it - unfortunately, your commit 
does not solve my issue.


I also tested with a new virgin user profile to make sure there isn't 
some old setting causing the troubles.


Custom widgets support is also not enabled.

[QGIS-Developer] Processing modeler GUI unusable in KDE / Plasma

Are there any KDE5 / Plasma users among the QGIS devs?

For me the GUI of the modeler is pretty broken - see screenshot at

[Qgis-developer] processing modeler: join attributes table

[Martin Landa]

Hi,

we are trying to join attribute table with another table in processing
modeler (using "Join attributes table" algorithm), but it fails:

"""
Running Join attributes table [2/2]

Parameters: INPUT_LAYER
=/tmp/processingb49e46d91a8d4997a4d2c2b0a2e31e7c/94a754a43e4a4074bcbd79714a0eebcf/OUTPUTALGQGISUNION1.shp,
INPUT_LAYER_2 =/home/landa/Documents/YFSG/hydrologie/hydrologie/vzorek1/hpj.shp,
TABLE_FIELD =HPJ, TABLE_FIELD_2 =HPJ

Failed

Error executing algorithm Join attributes table
QgsFeature.setGeometry(QgsGeometry): argument 1 has unexpected type
'NoneType' See log for more details
"""

The parameters should be fine - the both tables (attribute table and
CSV table contain column 'HPJ'). It's possible to join CSV table file
with attribute table manually in QGIS without any problems. It seems
to be a bug in processing modeler, can you confirm it?

Thanks, Martin

[Qgis-developer] [Processing] Modeler widget wrapper

[Arnaud Morvan]

Hello all,

I've proposed a refactoring of the modeler algorithm dialog :

https://github.com/qgis/QGIS-Enhancement-Proposals/issues/84

This would come with code simplification, more modularity and port all 
the functionnalities from the algorithm dialog to the modeler algorithm 
dialog.


But as this also has a side effect on the UI, I'd like to have more 
opinion before going deeper on this.


Best regards.

Arnaud Morvan

[Qgis-developer] Processing Modeler regression Unable to open datasource of intermediate results

[Anita Graser]

Hi,

There seems to be a regression between Processing 2.9 and 2.10 where 2.10
fails to run models because it cannot find the intermediate results it
produced in a previous step. The model runs perfectly in 2.9. Bellow you
can see an example to reproduce: just chain QGIS buffer and OGR dissolve
and it fails because it's looking for a file
:\Users\agraser\AppData\Local\Temp\processing\7f77fa47bcec4799818d1f5ea41cc8a9\OUTPUT.sh
(without C: and .sh instead of .shp)

Are you already aware of this or should I open a ticket.

Best wishes,
Anita

Sounds familiar - must have been reported somewhere else already - not sure if
I know it from a ticket.

Hi,
I reported this already some weeks ago: https://hub.qgis.org/issues/13174
My suspicion was, that this is related to GDAL processes, cause all others  
seem to run fine.

[Qgis-developer] [Processing] Modeler-only tools : Calculator

[rldhont]

Hi dev,

I discovered the Modeler-only tools : Calculator and I would like to 
know how to use it.

Does anyone have documentation on this specific algorithm ?

In the algorithm ui, there is only :
'You can refer to model values in you formula, using single-letter 
variables, as follows:'
