django User model operation
this tutorial will guide us to know how to manipulate django User model.
Read User object derived from database
from django.contrib.auth.models import User # Those two lines are different even if there is only one user 'admin' who registered before auser = User.objects.get(username = 'admin') # unique only one var
buser = User.objects.filter(username = 'admin') # var type the same as " allusers " allusers = User.objects.all()
Now let's check out how it shows.
in python shell,
>>>allusers
[<User: admin>]
>>>auser
<User: admin>
>>>buser
[<user: admin>]
>>>allusers == buser
Flase
Now let's see how to write data for User
Creating users
The most direct way to create users is to use the included create_user() helper function:
>>> from django.contrib.auth.models import User
>>> user = User.objects.create_user('john', 'lennon@thebeatles.com', 'johnpassword') # At this point, user is a User object that has already been saved
# to the database. You can continue to change its attributes
# if you want to change other fields.
>>> user.last_name = 'Lennon'
>>> user.save()
If you have the Django admin installed, you can also create users interactively.

authenticate (验证身份）
the operation downside will directly talk to database model
from django.contrib import auth
user = auth.authenticate(username='john', password='secret')
if user is not None:
print "Correct!"
else:
print "Invalid password."
