Django实现用户注册登录

学习Django中：写一个用户注册登录系统，开始搞事情 =====O(∩_∩)O~=====

=================

Ubuntu

python 2.7.12

Django 1.10.4

IDE：Pycharm

Bootstrap

=================

新建项目：（我是直接用pycharm直接生成的）

使用终端：

(创建项目) django-admin.py startproject mysite

(进入mysite新建app) django-admin.py startapp app01

记得在settings.py里面添加app

设计模型：

/mysite/app01/models.py：

1 from __future__ import unicode_literals2 3 from django.db import models4 5 # Create your models here.6 7 class User(models.Model):8username = models.CharField(max_length=50)9password = models.CharField(max_length=50)10email = models.EmailField()

创建User类，存放 username、password、email三个字段

同步数据库：

Python manage.py makemigrations

python manage.py migrate

Django会自动创建一系列表

没有自动创建superuser.......咱们手动创建：

python manage.py createsuperuser

设计逻辑视图（views）：（使用表单）

/mysite/app01/views.py：

1 #coding=utf-82 from django.shortcuts import render,render_to_response3 from django.http import HttpResponse4 from django import forms5 from models import User6 # Create your views here.7 class UserForm(forms.Form):8username = forms.CharField(label='用户名',max_length=50)9password = forms.CharField(label='密码',widget=forms.PasswordInput())10email = forms.EmailField(label='邮箱')11 12 def regist(request):13if request.method == 'POST':14 userform = UserForm(request.POST)15 if userform.is_valid():16 username = userform.cleaned_data['username']17 password = userform.cleaned_data['password']18 email = userform.cleaned_data['email']19 20 User.objects.create(username=username,password=password,email=email)21 User.save()22 23 return HttpResponse('regist success!!!')24else:25 userform = UserForm()26return render_to_response('regist.html',{'userform':userform})27 28 def login(request):29if request.method == 'POST':30 userform = UserForm(request.POST)31 if userform.is_valid():32 username = userform.cleaned_data['username']33 password = userform.cleaned_data['password']34 35 user = User.objects.filter(username__exact=username,password__exact=password)36 37 if user:38 return render_to_response('index.html',{'userform':userform})39 else:40 return HttpResponse('用户名或密码错误,请重新登录')41 42else:43 userform = UserForm()44return render_to_response('login.html',{'userform':userform})

注释:

label：标签

widget:装饰

widget=forms.PasswordInput():设置密码字段

设计模板文件

在templates里面新建index.html、regist.html、login.html

regist.html

<!DOCTYPE html>{% load static %}<html lang="zh-CN"><head><meta http-equiv="content-type" content="text/html; charset=UTF-8"><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1"><meta name="description" content=""><meta name="author" content=""><title>Regist</title><link href="{% static 'css/bootstrap.css' %}" rel="stylesheet"><link href="{% static 'css/ie10-viewport-bug-workaround.css' %}" rel="stylesheet"><link href="{% static 'css/signin.css' %}" rel="stylesheet"><script src="{% static 'js/ie-emulation-modes-warning.js' %}"></script></head><style>html,body{text-align:center;margin:0px auto;}</style><body><h1>注册页面</h1><form method = 'post' enctype="multipart/form-data">{{userform.as_p}}<input type="submit" value = "Regist" /></form></body></html>

<!DOCTYPE html>{% load static %}<html lang="zh-CN"><head><meta http-equiv="content-type" content="text/html; charset=UTF-8"><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1"><meta name="description" content=""><meta name="author" content=""><title>Login</title><link href="{% static 'css/bootstrap.css' %}" rel="stylesheet"><link href="{% static 'css/ie10-viewport-bug-workaround.css' %}" rel="stylesheet"><link href="{% static 'css/signin.css' %}" rel="stylesheet"><script src="{% static 'js/ie-emulation-modes-warning.js' %}"></script></head><style>html,body{text-align:center;margin:0px auto;}</style><body><h1>登录页面</h1><form method = 'post' enctype="multipart/form-data">{{userform.as_p}}<input type="submit" value = "Login" /></form></body></html>

index.html

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>主页</title></head><style>html,body{text-align:center;margin:0px auto;}</style><body><h1>Hello Word!</h1></body></html>

设计urls

/mysite/urls.py

from django.conf.urls import url,includefrom django.contrib import adminfrom app01 import urlsimport app01urlpatterns = [url(r'^admin/', admin.site.urls),url(r'',include(app01.urls)),]

/mysite/app01/urls.py

from django.conf.urls import url,includefrom django.contrib import adminimport viewsadmin.autodiscover()urlpatterns = [url(r'^index/$',views.index),url(r'^login/$',views.login),url(r'^regist/$',views.regist),]

使用admin后台管理注册的用户

在models.py里面设计一个UserAdmin类，用来记录注册用户的信息

/mysite/app01/models.py

from __future__ import unicode_literalsfrom django.contrib import adminfrom django.db import models# Create your models here.class User(models.Model):username = models.CharField(max_length=50)password = models.CharField(max_length=50)email = models.EmailField()class UserAdmin(admin.ModelAdmin):list_display = ('username','password','email')admin.site.register(User,UserAdmin)

同步一下数据库（方法同上）
