学习Django中:试着着写一个用户注册登录系统,开始搞事情 =====O(∩_∩)O哈哈~=====
=================
Ubuntu
python 2.7.12
Django 1.10.4
IDE:Pycharm
Bootstrap(其实没怎么用~~)
=================
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:
from __future__ import unicode_literals 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()
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:
#coding=utf-8 from django.shortcuts import render,render_to_response from django.http import HttpResponse from django import forms from models import User # Create your views here. class UserForm(forms.Form): username = forms.CharField(label='用户名',max_length=50) password = forms.CharField(label='密码',widget=forms.PasswordInput()) email = forms.EmailField(label='邮箱') def regist(request): if request.method == 'POST': userform = UserForm(request.POST) if userform.is_valid(): username = userform.cleaned_data['username'] password = userform.cleaned_data['password'] email = userform.cleaned_data['email'] User.objects.create(username=username,password=password,email=email) User.save() return HttpResponse('regist success!!!') else: userform = UserForm() return render_to_response('regist.html',{'userform':userform}) def login(request): if request.method == 'POST': userform = UserForm(request.POST) if userform.is_valid(): username = userform.cleaned_data['username'] password = userform.cleaned_data['password'] user = User.objects.filter(username__exact=username,password__exact=password) if user: return render_to_response('index.html',{'userform':userform}) else: return HttpResponse('用户名或密码错误,请重新登录') else: userform = UserForm() 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
<!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"> <!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! --> <meta name="description" content=""> <meta name="author" content=""> <title>Regist</title> <!-- Bootstrap core CSS --> <link href="{% static 'css/bootstrap.css' %}" rel="stylesheet"> <!-- IE10 viewport hack for Surface/desktop Windows 8 bug --> <link href="{% static 'css/ie10-viewport-bug-workaround.css' %}" rel="stylesheet"> <!-- Custom styles for this template --> <link href="{% static 'css/signin.css' %}" rel="stylesheet"> <!-- Just for debugging purposes.

login.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"> <!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! --> <meta name="description" content=""> <meta name="author" content=""> <title>Login</title> <!-- Bootstrap core CSS --> <link href="{% static 'css/bootstrap.css' %}" rel="stylesheet"> <!-- IE10 viewport hack for Surface/desktop Windows 8 bug --> <link href="{% static 'css/ie10-viewport-bug-workaround.css' %}" rel="stylesheet"> <!-- Custom styles for this template --> <link href="{% static 'css/signin.css' %}" rel="stylesheet"> <!-- Just for debugging purposes.

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,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)
