Hi all,
is it possible to write a custom Processing script that can edit the
input layer in place (with the core functionality of course)?
In the documentation I found the method to check if the algorithm
supports the in place editing [0] but not the method to set the script
to support the functi
Hello Matteo,
As far as I know, if your algorithm :
does not change the table structure (geometry type, fields list and
their types)
is an instance of QgsProcessingFeatureBasedAlgorithm (output one
feature for each input feature)
In brief:
- If your algorithm output one featur
Note that when heriting form QgsProcessingFeatureBasedAlgorithm,
you do not have to implement processAlgorithm method which is already
implemented in QgsProcessingFeatureBasedAlgorithm
but should implement the processFeature method.

Hi Arnaud,
I explored the QgsProcessingFeatureBasedAlgorithm but unfortunately is
not the case of what I'm looking for. From what I understood
QgsProcessingFeatureBasedAlgorithm is the class to use when the
algorithm performs "feature-by-feature" operations like buffers.
In my case I would like t
Hi Matteo,
yes, it's possible to write custom Processing scripts for editing layers
in-place.
Here you can find an example (buffer):

Hola Germàn,
thanks for the hint. While it is perfectly working on QGIS 3.10
installed from repository. QGIS is crashing with the same data and the
same script in QGIS master (compiled yesterday). Are there any API problems?
Cheers and thanks!

Hi Matteo,
not sure what exactly you want to achieve, but you can do a union and
dissolve by doing a buffer with zero buffer distance and enabling the
dissolve result checkbox.

Hi Stefanos,
yep, but digging into this I was wondering how to use the EditInPlace
also for scripts :)
Cheers and thanks for the hint

Hi Matteo,
the sample script I mentioned in my previous e-mail in this thread
should be working on master now. Nyall fixed the bug reported.
