[Qgis-user] GRASS Error Popup in Python Console
While running a script in the Python console in QGIS v3.16.10, I intermittently get a GRASS error pop-up. The pop-up is a small box saying "unfortunately GRASS 7 has stopped working, please close the program". The program doesn't continue further in execution when this is shown. Has anyone else had to troubleshoot this error or found a workaround? Thanks, Jon. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] PyQgis - PostGIS layers won't show in export to PDF (layout)
If your local files are exporting but nothing is being pulled from the
database I would suspect an authentication/ permissions issue.
There are a number of ways that QGIS/PG authentication can work in a
project, mainly:
- Basic (plaintext) stored in the QGIS Project - Insecure and not
recommended, but convenient if you want to make a copy of your project
- Auth manager - Each user profile has it's own qgis-auth.db which is
sqlite. You would need to share different auths between users and projects
by using the same authid. Note that I don't think that loading the QGIS
project from PyQGIS is automatically going to load your auth config though,
and it may need to be instantiated in your script [1]. My suspicion is that
you are using this method and the QGIS GUI unlocks it for you, resulting in
the varied result. You could always try to run most of your script from the
python console in the project to check if that works too.
- PGSERVICE - You can also use pg_service.conf (it even supports
password=), or similar connection environment variables, which is both
convenient and significantly more secure than plaintext credentials in the
project. If managed well it can offer a good level of security, but a word
of caution is that misuse of it can be a lot more dangerous from a security
persepctive. Good for testing purposes though... But note that the way
layers are defined and loaded in a project file will vary between service
based connections and those managed by the auth manager.
You can also make a new (or copy an existing) user profile to define the
database connection to prevent the risk of breaking your existing project
and db configs.
I think doing some quick tests to verify whether or not it is an
authentication issue is recommended, because auth management can be a bit
of a rabbit hole.

[Qgis-user] Resource Location Error with new installation on SUSE Leap 15.2
Hello, I have a new installation of QGIS 3.16 long term release (Hannover) on Suse Leap 15.2 Linux. However, it hangs when I try to add an existing layer to a new project. The window for opening an existing file has the title ''Resource location error". Opening an exiting project crashes QGIS immediately. Does anyone know how to solve this? Never had problems with QGIS on Suse Linux before Ko van Huissteden ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Need help with changing CRS
Hi, As David said, the key point here is that you should not change the layers' CRS (unless it's wrong ofc). Keeping the data original CRS and changing the project CRS will tell QGIS that on-the-fly transformation is needed for that layer. This will make you layer, originally in EPSG:4326, look like it's in the project CRS.

Re: [Qgis-user] How to make a table in a subsection report
I only faintly remember making a report last year with a similar problem (maps of photo destinations on different sections of a highway). I think I solved it by adding new columns of combined indices with the subsection (your grid) and the photo-id, because there way no way to do this within the report. Haven't touched the tool since then, cause every redecision on how to design the report lead to a complete new start from scratch, which took too much time. Not sure if it hits your problem. As I said, can't remember well. Good luck, Bernd On 18.08.21 08:53, Dario wrote: Hi, I have a report with a primary dynamic section where I have a map with a controlled layer (indexed grid).
