Filter[Question]: Filter temporal data by user

[BaBoWaGa]

What is the question? (in English)

Hi, I have a time manager on a postGIS layer with daily start and end date. Is there a way to limit data display based on logged in user?
Example:
alpha user can see data from 1 to 5 March 2024
beta user can see data from February 1 to March 5, 2024
gamma user can see the entirety of the data

Lizmap 7.5 QGIS 3.28.15

Versions, safeguards, check summary etc

Lizmap 7.5 QGIS 3.28.15

Check Lizmap plugin

• I have done the step just before in the Lizmap QGIS desktop plugin before opening this ticket. Otherwise, my ticket is not considered valid and might get closed.

Did you check the documentation here ?

Yes, thanks, I managed to do something by following those instructions, the only thing I didn't understand is how and if I can hide the display of some fields depending on the logged in user.

if I can hide the display of some fields depending on the logged in user.

It's not possible with Lizmap.
Maybe with some Javascript, but I doubt and it wouldn't be secure/safety because all the data will still be in the webbrowser.

Maybe with a script like this

layer = QgsProject.instance().mapLayersByName('Your_layer_name')[0]  # Make sure to replace 'Your_layer_name' with the actual name of your layer

# Check if the web user is in the lizmap_user and/or lizmap_user_groups list
web_user = 'web_username'  # Replace with the actual web user's name
user_group = 'user_group'  # Replace with the actual user's group name

# Check if the web user is in the lizmap_user list
if web_user in layer.customProperty("lizmap_user"):
    # If the web user is present, select the fields to display
    fields_to_display = ['field1', 'field2', 'field3']
else:
    # If the web user is not present, select a different set of fields to display
    fields_to_display = ['alternative_field1', 'alternative_field2']

# Update the display of fields in the layer
layer.setSubsetString('"field_name" IN {}'.format(tuple(fields_to_display)))

This is Python, so it can only run as a Python plugin for QGIS server.
