I am using flask-sqlalchemy , and flask login. 

Flask login requires a user object to identify the current user. 

So I give it something like : 

user = User(id=1)

where User is an flask-sqlalchemy db model. 

Note that this does not actually perform a query to the db. 

Later on, I may want to access the email attribute of user, so I would do : 
user.email. 
Now I would expect a db query to be run and fetch the email from the 
database. 

There seems to be some discussion about this issue , but I was unable to 
find a proper solution for it. 

Some help will be great
