How can i check that demo data is loaded or not in a database by code

Question

How can i check that demo data is loaded or not in a database from python code.I know other ways to check , but i need to check it by code.

Answer 1

I think the easiest way to do is by checking if the XML-ID is loaded :

         # checking if the demo user record exist in database
         # don't forget the put the full qualifying XML-ID (addon_name.xml_id) 
         if not self.env.ref('base.user_demo', raise_if_not_found=False):
               # demo user is not loaded in database

Odoo maps the XML-ID with the real ID in database using this model ir.model.data if the record is loaded ref will return the record from the database else it will raise an exception or return None based on the second argument raise_if_not_found by default it's True
