Bug report #18095

Grass algorithm outputs do not correctly work within models

Description

"Extract layer extent" does not work in processing model in master if input layer is also a "final result".
The attached model is a simple test case. Try changing it so the output of v.to.rast is not a "final result", and everything will work!

Prepare algorithm: qgis:polygonfromlayerextent_2
Running Extract layer extent [2/2]
Input Parameters:
{ INPUT: , OUTPUT: 'memory:' }
Traceback (most recent call last): File "/usr/share/qgis/python/plugins/processing/algs/qgis/ExtentFromLayer.py", line 96, in processAlgorithm fields, QgsWkbTypes.Polygon, layer.crs()) AttributeError: 'NoneType' object has no attribute 'crs'

History

#1 Updated by Nyall Dawson over 2 years ago

  • Category changed from Processing/QGIS to Processing/GRASS
  • Subject changed from "Extract layer extent" does not work in processing model in QGIS 3 if input layer is also a "final result" to Grass algorithm outputs do not correctly work within models

Specific to GRASS algorithms only.

#2 Updated by Nyall Dawson almost 2 years ago

  • Resolution set to fixed/implemented
  • Status changed from Open to Closed

Fixed in 3.3
