I need help for a program I'm trying to use in QGIS. Let me explain:
I have two files:
What I thought was creating a field type date[] (both files are in PostgreSQL/PostGIS) and, after selecting the row of the dbf and the polygons, run an algorith that calculates the hour (year-month-day-hour-minute-second) and put this data in the date[] field of both files. Therefore, with a simple join operation using the date[] field I can know geometric and alphanumeric information.
I know this, with the field calculator, is the function '$now', but I don't know how to run this function in PyQGIS.
I thank you every help you could give me
Greetings
