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_literals
2
3 from django.db import models
4
5 # Create your models here.
6
7 class User(models.Model):
8 username = models.CharField(max_length=50)
9 password = models.CharField(max_length=50)
10 email = 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-8
2 from django.shortcuts import render,render_to_response
3 from django.http import HttpResponse
4 from django import forms
5 from models import User
6 # Create your views here.
7 class UserForm(forms.Form):
8 username = forms.CharField(label='用户名',max_length=50)
9 password = forms.CharField(label='密码',widget=forms.PasswordInput())
10 email = forms.EmailField(label='邮箱')
11
12 def regist(request):
13 if 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!!!')
24 else:
25 userform = UserForm()
26 return render_to_response('regist.html',{'userform':userform})
27
28 def login(request):
29 if 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
42 else:
43 userform = UserForm()
44 return 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
{% load static %}
Regist
注册页面
login.html
{% load static %}
Login
登录页面
index.html

Hello Word!
设计urls
/mysite/urls.py
from django.conf.urls import url,include
from django.contrib import admin
from app01 import urls
import app01
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'',include(app01.urls)),
]
/mysite/app01/urls.py
from django.conf.urls import url,include
from django.contrib import admin
import views
admin.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_literals
from django.contrib import admin
from 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）
