Answer 1 seems a good one. Can you help me on how to override? I already have inherited the class, but I don't know how to exactly override a function, do I need to call "super" so the method works like the parent method plus my functionality?

You just need to re-define the method in the inherit class. Yes, it is better that you call super to get the proper return value. Say that you want to inherit create method, below the inherit class add the following: def create(self, cr, uid, vals, context=None): # Then add your logic here before calling super res = super(inherit_class, self).create(cr, uid, vals, context=context) # You can add further logic here after the super call return res. If the formatting of comment screw it up, you basically need to redefine the method, add your logic, call super, add further logic, then return the return of super (or something else if you really know what you want to return).

Done! Thank you so much! I had to return a different value from the original super return value. Simply because user can't watch the partner if it belongs to another company. Thank you so much
