Django's Auth module

First, let's review how the route aliases are used, just review the route aliases for level two routing how to use

• 1. Use a level two routing alias in the View function, plus the name of the app + ":" + "Routing alias"

From django.urls import Reversereturn redirect (reverse ("App1:auth_index_view"))

　　

2. Use the alias of level two route in HTML file

<form action= "{% url ' app1:auth_login_view_name '%}" method= "POST" Novalidate >    {% csrf_token%}    {{ Obj.username.label_tag}}{{Obj.username}}    <span>{{obj.errors.username.0}}</span>    {{ Obj.userpwd.label_tag}}{{Obj.userpwd}}    <span>{{obj.errors.userpwd.0}}</span>{#    <a href= " {% url ' app1:auth_login_view_name '%} "> Point me Big </a>#}    <input type=" Submit "value=" Commit "></form>

　　

Below we formally enter the Auth module study

1, first need to import two modules

From Django.contrib Import Auth

　　

From django.contrib.auth.models import user# Creating a user's module

　　

2, then here is the specific method of use of the Auth module

def auth_login_view (request): Method_type = Request.method.lower () if Method_type = = "Get": Form_obj = my_new _forms () return render (Request, "auth_login.html", {"obj": form_obj}) Else:username = R Equest. Post.get ("username") Userpwd = Request. Post.get ("userpwd") user = Auth.authenticate (username=username,password=userpwd) # This must be user with no other, verify the username and password Whether through validation, if passed returns a Usr object, and if not, returns an anonymous user object if User:auth.login (request,user) # encapsulates username this information into R  Equest.user Print (dir (user)) from django.contrib.auth.models Import user New_common_user  = User.objects.create_user () # Create normal User New_super_user = User.objects.create_superuser () #            Create Super Admin user Error_create_user = User.objects.create () # We don't use this method to create a user, this method creates a user's password is not encrypted, and generally can not be used user = User.objects.get (username= "AAA") User.set_password () user.save () # Change password, here need to save to take effect User.check_password () # When the user needs to change the password, first determine the current input password is correct RET Urn Redirect (reverse ("App1:auth_index_view")) Else:return Redirect (Reverse ("App1:auth_login_view_name") )

　　

3, auth module also comes with an adorner, used to determine whether the user login, you also need to import a module first

From django.contrib.auth.decorators import login_required# to determine whether the user is logged in the adorner

　　

@login_required # Django's own decorator to determine if a user is logged on to Def auth_index_view (request):    print (request.user.is_authenticated ())    # Determine if a user is logged in, if yes returns true return    render (request, "auth_index.html", {"name": Request.user.username})

　　

If the user does not log in successfully, then the page needs to jump to a page, this page needs to be configured in Settings

# If there is no landing land, the default jump to which Urllogin_url = "http://www.baidu.com"

　　

4, the method of Auth module cancellation

def logout (Request):    auth.logout (Request)    # Auth.logout method, delete the cookies and seesion    return redirect (Reverse (" App1:auth_login_view_name "))

　　

In addition, there are only a limited number of fields in the Django Default User table, and if we want to expand the fields we have, we have 2 ways to deal with them.

Method 1, create a new table, one to the user table

# 1, create a new table, one-to Auth_User table from django.contrib.auth.models import user# First, the Django-brought User table is imported into class User_detail (models. Model):    phone = models. Charfield (max_length=11)    usr_obj = models. Onetoonefield (To=user)    # A one-to-one link to the Django-brought User table

　　

Method 2, using the inherited method, it is important to note that if you use the inherited method, the Django database has a auth_user table, so the above method if you use auth_user this table, then only need to modify the table name to indicate that we

# 2, write a class from django.contrib.auth.models import userfrom django.contrib.auth.models import Abstractbaseuserclass Userinfo (abstractbaseuser):    phone = models. Charfield (max_length=11)    addr = models. TextField () # If we use inheritance to extend the built-in Auth_User table, this is the time to configure the default user to authenticate with the table # Auth_user_model = "App1" in settings.py. Userinfo "
