django can't find slicer

[SaibotMagd]

Hi, it seems like there at least 2 issues, so this proof-of-concept can't work:

• without any changes django can't find slicer:
  `
  DEBUG:omeroweb.settings:INSTALLED_APPS=[('django.contrib.staticfiles', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'omero_figure', 'omero_iviewer', 'omero_mapr', 'omero_parade', 'omero_autotag', 'omero_tagsearch', 'slicer', 'corsheaders', 'omeroweb.feedback', 'omeroweb.webadmin', 'omeroweb.webclient', 'omeroweb.webgateway', 'omeroweb.webredirect', 'omeroweb.api', 'pipeline')]

`

But why does django even look at this python3.9 env as the path in "docker-compose.yml" looks like:

omeroweb: # This container uses the tag for the latest web release of OMERO 5 # To upgrade to the next major release, increment the major version number image: "openmicroscopy/omero-web-standalone:5.23.0" container_name: omeroweb_docker environment: OMEROHOST: omeroserver networks: omero: ipv4_address: 172.20.0.3 ports: - "4080:4080" volumes: - "/home/cni/slicer-omero/omero_web_extension_volume:/opt/omero/web/venv3/lib/python3.6/site-packages/slicer" #Replace > - "/home/cni/slicer-omero/omero_web_conf_volume/config.omero:/opt/omero/web/config/config.omero" #Replace the first dir> - "/home/cni/slicer-omero/slicer_volume:/home/Documents/slicer_volume" #Replace the first directory with its volume.Thi>

So you can replace the environment with "python3.9" and it will work. But it still can't write into the "/home/cni/slicer-omero/slicer_volume/ids/" folder to write the temporary json file. Therefore the container must be given access rights to this folder.

Also it seems like django 4.0 can't use the url function anymore, so I had to change it to another command:

After all of these steps, you can start 3d-slicer from omero but it shows no image at all...
