I have postgresql/postgis database setup with one to many relationship. I can successfully set it up in QGIS but i would like to keep related tables hidden from Layers Panel to keep the project "clean" since later on i might be adding more complex databases, value map tables etc..
For example, i have locations layer where each point can relate to several events in events layer. I would like to edit data in form like this so each location can be updated with new events only that events table would not be visible in Layers Panel:
I found solution that works in QGIS 2 but i need to set it up in QGIS 3.
Is there some way to achieve this without going into PyQGIS?
I am just starting with PyQGIS.
