django做简单的用户登录和增删改查
本人是用eclipse做的，环境是python2.7、django1.9.13,创建完项目后在cmd启动一个app,python manage.py startapp login,这个命令如果说没有就创建这个application
1.在settings.py
配置数据库
DATABASES = {
'default': {'ENGINE': 'django.db.backends.mysql',
'NAME': 'test_cgd',
'HOST':'127.0.0.1',
'PORT':'3306',
'USER':'root',
'PASSWORD':'123456',
}
}
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'login', #添加应用
)
在views.py中编写主要逻辑代码
# -*- coding: utf-8 -*-
from django.http import HttpResponseRedirect, HttpResponse
from django.shortcuts import render_to_response
from django.template import RequestContext
from models import User
from django.shortcuts import redirect,HttpResponse
from django.core.urlresolvers import reverse
from django.shortcuts import render
from django.forms import fields
from captcha.fields import CaptchaField
from django import forms
import os,datetime
from django.contrib.auth.decorators import login_required
#登录
def login(request):
if request.method == 'POST':username = request.POST.get("username")
password = request.POST.get("password")
#对比输入的用户名和密码和数据库中是否一致
print (username)
print (password)
user = User.objects.filter(username__exact=username,password__exact=password)
if user :
response = HttpResponseRedirect('/userlist/')
response.set_cookie('cookie_username',username,3600)
return response
else:
return render_to_response('login.html')
else:
return render_to_response('login.html',context_instance=RequestContext(request))
#列表所有用户
def user_list(request):
u_list = User.objects.all()return render_to_response('userlist.html',{'u_list':u_list})
#添加用户
def add_user(request):
if request.method == "GET":
return render_to_response('adduser.html')
elif request.method == "POST":
username = request.POST.get('username')
password = request.POST.get('password')
email = request.POST.get('email')
phone = request.POST.get('phone')
User.objects.create(username=username,password=password,email=email,phone=phone)
return HttpResponseRedirect('/userlist/')
#编辑用户
def edit_user(request,nid):
if request.method == "GET":
obj = User.objects.get(id=nid)
return render_to_response('edituser.html',{'obj': obj})
elif request.method == "POST":
username = request.POST.get('username')
password = request.POST.get('password')
email = request.POST.get('email')
phone = request.POST.get('phone')
User.objects.filter(id=nid).update(username=username,password=password,email=email,phone=phone)
return HttpResponseRedirect('/userlist/')
#删除用户
def del_user(request,nid):
User.objects.filter(id=nid).delete()
return HttpResponseRedirect("/userlist/")

最后在urls.py
# -*- coding: utf-8 -*-
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns("",
url(r'^admin/', include(admin.site.urls)),
url(r'^upload/$', 'login.views.upload',name='upload'),
url(r'^login/$', 'login.views.login',name='login'),
url(r'^userlist/$', 'login.views.user_list',name='userlist'),
url(r'^adduser/$', 'login.views.add_user',name='adduser'),
url(r'^edituser/(\d+)/$', 'login.views.edit_user',name='edituser'),
url(r'^deluser/(\d+)/$', 'login.views.del_user',name='deluser'),
)
简单的练习，希望对初学者有帮助。
