One, auth module
1) What is the Auth module? Login background using the account password, is the use of the Auth module created by the table
The auth module is a django-brought user authentication module: When we develop a website, it is unavoidable to design a user system that implements the website. At this time we need to implement including user registration, user login, user authentication, logout, change password and other functions, this is really a troublesome thing. Django, as the ultimate framework for perfectionism, will of course think of the user's pain points. It has built-in a powerful user authentication system -auth, which uses the Auth_User table to store user data by default.
2) function of auth module
2.1) Import Auth module
from Django.contrib import auth
2.2) method under the Auth module. Authenticate (). Authentication function
= Authenticate (username='usernamer', password='password')
The specific use is as follows
fromdjango.contrib Import authdef auth_test (Request): Username= Request. post['username'] Password= Request. post['Password'] User= Auth.authenticate (Username=username, password=password)ifuser:print (user.username)returnHttpResponse ("Login Successful") returnHttpResponse ("Logon Failure")Authenticate use
2.3) Login (Request,user). Login function (after successful authentication)
Auth.login (Request,user)from django.contrib Import authdef auth_test (Request): = Auth.authenticate (request,username='user2', password='user123456 ' # Authentication print (user) if user : print (user.username) # login Username Auth.login (request,user) return render (request,'auth_test.html ')
Once logged in, the front end can also get the login user name
<body><div>{{Request.user}}</div></body>The front end can also be used to determine whether the request passed.
<body><div>{{request.user}}</div><div>{{request.user.is_authenticated}}</div> </body>2.4) Auth.logout (Request). User Exit method
def auth_test_logout (request): auth.logout (Request) return httpresponse (' Exit success ')Second, auth module expansion. For creating users, login adorners
1) New fields
1.1) Modify the configuration file settings.py
settings.py" app name. User Name Table " "app01. UserInfo" # Specify table
1.2) Create a table that inherits Abstractuser. Overridable table Structure
Abstractuserfrom django.contrib.auth.models Import Abstractuser class UserInfo (abstractuser): = Models. Autofield (primary_key=True) = models. Charfield (max_length=)
2) Create user
def auth_test_creat_user (Request): # admin UserInfo.objects.create_superuser (username='USERSB1', password=123, email='[email protected]') # Ordinary user UserInfo.objects.create_user (username='USERSB2', password=123, email='[email protected]') returnHttpResponse ('Success')Creat_user
3.1) Login Adorner method one. The view function is preceded by a URL
@login_required (login_url='/auth_test_login/') # operation def Auth_test_ after login Logout (Request): auth.logout (Request) return httpresponse (' exit successful ')Login_url= '/auth_test_login/', no login jumps to the URL
3.2) Login Adorner method two. Settings Global Configuration
settings.py' /auth_test_login/ '
You don't have to add a URL before the view function
@login_required # operation can be done after login Def auth_test_logout (request): auth.logout (Request )return HttpResponse (' exit succeeded '4) Check the password. Check_password (password).
The password returns true correctly, otherwise false is returned.
= User.check_password (' password ')if tag: print (" OK " )else: print (" error ")5) Change the password. Set_password (password)
Set_password (password= ")Auth provides a way to change the password, receiving the new password to be set as the parameter. Note: Be sure to invoke the Save method of the User Object!!! Usage: user.set_password (password=") User.save ()
An example of a simple password change
@login_requireddef Set_password (Request): User=Request.user err_msg="' ifRequest.method = ='POST': Old_password= Request. POST.Get('Old_password',"') New_password= Request. POST.Get('New_password',"') Repeat_password= Request. POST.Get('Repeat_password',"') # Check that the old password is correctifUser.check_password (old_password):ifNot new_password:err_msg='The new password cannot be empty'elif New_password!=repeat_password:err_msg='two times password inconsistency' Else: User.set_password (New_password) user.save ()returnredirect"/login/") Else: Err_msg='Original Password input error'content= { 'err_msg': Err_msg,}returnRender (Request,'set_password.html', content)View Code
6) Properties of the user object
View CodeUser Object properties: Username, Passwordis_staff: Whether users have administrative rights on the site. Is_active: Whether the user is allowed to log on and set to False can prevent users from logging on without deleting the user.
