[QGIS-Developer] Running python file from a different environment
Hello, I would like to know whether you can run or execute a diferent python file via qgis console using a different environment? Here i mean, i want to run it on its own environment where all dependecies are set.

I think leaving the conditional checks is needed, but its definitely it's worth exploring if the dependencies can be added to the default windows install...

[QGIS-Developer] updating a model on the site
Hi, I have a 3 models that have been improved (Fix Directional Network, Check Geometries, model 1 of 3.) and fixed. I presented today at the QGIS OpenDay. I had to remove the "Snap to anchor nodes (single layer only)" as it was creating invalid geometries in QGIS 3.28.2-Firenze on Windows 11. I am not sure exactly how to upload the new models? I see the upload button but I am wondering what will happen to the old ones? Will they be removed by someone managing the site? Can we have multiple versions of the model as I am using the new repair geometry tools unavailable before 3.28? Is it possible to modify a models' description myself or must I send and email somewhere?

Re: [QGIS-Developer] parameterAsEnumStrings always return default value
Hi Andrea, Thanks for your reply. The doc should reflect this weird (I believe) behavior. Setting "usesStaticStrings=True" and "defaultValue="2023" and with parameterAsEnumString I have expected behavior but parameterAsEnum is broken... Not easy... I think I will fill an issue as the doc should should be more explicit or behavior fixed.

Re: [QGIS-Developer] PyQGIS code: setting filter expression for value relation widget
Hi Germán,
Thank you so much for these suggestions and code snippets.
I also came across the QgsEditorWidgetSetup - but had no idea how to use
it. The Python cookbook did not mention it. The cookbook is really great -
but for interactive forms, there is not so much information.
I will try it and report back.
Thank you very much Germán,
Andreas

Re: [QGIS-Developer] parameterAsEnumStrings always return default value
Hi Nicolas, I don't know if it is the intended behaviour, anyway it seems to me parameterAsEnumString and parameterAsEnumStrings return the correct value when |usesStaticStrings is set to True, while parameterAsEnum and parameterAsEnums when ||usesStaticStrings is set to False. In addition, the parameter defaultValue should be set to a single value and not to a list if ||allowMultiple is set to False. Best regards.

Re: [QGIS-Developer] Additional python modules
Hi, last time I checked there wasn't, mainly because the PIP API wasn't exposed. The standard way to go is ask Juergen to add the packages you need to the QGIS package recipes.

[QGIS-Developer] Additional python modules
Hello everyone, I'm working on a new feature targeting 3.32 to reformat code written in the Python Console Editor : https://github.com/qgis/QGIS/pull/51733. It works great, but it requires additional python packages to be installed (namely black / autopep8 / isort). *Is there a reliable cross platform way we can use to distribute additional python packages alongside QGIS? * I could rewrite my PR to enable this feature only if the required modules are installed, but it seems kind of a shame...

Dear devs,
I noticed in a custom alg that `parameterAsEnumStrings` always return the
default value set in QgsProcessingParameterEnum.
Below a example alg to reproduce.
i prefere to start with an email before raising an issue as I could miss
something
In alg window select any value different from 2023 (ex: 2020, index 3 in list).
Run alg
