Another method which you can use is
====================================
for respective model override the save as follows
class Model():
#this code syntax may not be proper
def save(self):
super(self) #at this point it will save and you will know the id
self.account_number = "X"+self.id
self.save()
The syntax may be wrong as i have did not do it earlier
The core idea is to override the save and then call its parent to save
the object,after saving using that object id form account number
and save it again
