python - Whats the difference iterating over the queryset in these two ways? -

i using django building project , came across these 2 ways.

one way :

users = users.objects.filter(is_verified=true)  user in users:     print user.user.id 

and second way :

users = users.objects.filter(is_verified=true)  user in users:     print user.id 

at first thought first way wont work working , quite slow second way.

the first 1 looking @ user property inside of individual users object.

basically first 1 doing:

print users[x].user.id

the second doing:

print users[x].id

where x current index in for loop.

if there user property inside of users object, first correct. otherwise you'd want access id property of individual users object.

an example of users class first scenario be:

class users(object):   user = user() 

an example of users class second senario be:

class users(object):   id = 0 

i think what's happening when accessing user property on users object, may querying database again. if can include users class definition easier understand root problem.
