First, users create new forms.py
# _*_encoding:utf-8_*_
__author__ = 'wuhuhuan'
__date__ = '2020/4/18 11:42'
from django import forms
class LoginForm(forms.Form):
username = forms.CharField(required=True)
password = forms.CharField(required=True, min_length=5)
Second, users views.py adds forms judgment
# _*_ coding:utf-8 _*_
from django.shortcuts import render
from django.contrib.auth import authenticate, login
from django.contrib.auth.backends import ModelBackend
from django.db.models import Q
# 导入view类
from django.views.generic.base import View
from .models import UserProfile
# 导入loginForm 类
from users.forms import LoginForm
# Create your views here.
#新增定义 loginViw 方法继承View
class LoginView(View):
def get(self, request):
return render(request, "login.html", {})
def post(self, request):
login_form = LoginForm(request.POST)
# 新增判断是否必填、是否为空、字符长度判断
if login_form.is_valid():
user_name = request.POST.get("username", "")
pass_word = request.POST.get("password", "")
user = authenticate(username=user_name, password=pass_word)
if user is not None:
login(request, user)
return render(request, "index.html", {'nickname': user})
else:
return render(request, "login.html", {"msg": u"用户名或密码错误"})
else:
return render(request, "login.html", {"login_form": login_form})
class CustomBackend(ModelBackend):
def authenticate(self, request, username=None, password=None, **kwargs):
try:
user = UserProfile.objects.get(Q(username=username) | Q(email=username))
if user.check_password(password):
return user
except Exception as e:
return None
def user_login(request):
if request.method == 'POST':
user_name = request.POST.get("username", "")
pass_word = request.POST.get("password", "")
user = authenticate(username=user_name, password=pass_word)
if user is not None:
login(request, user)
return render(request, "index.html", {'nickname': user})
else:
return render(request, "login.html", {'msg': u"用户名或密码错误！"})
elif request.method == 'GET':
return render(request, 'login.html', {})
Fourth, modify login.html focus and corresponding prompt judgment
