學習Django中：試著著寫一個用戶注冊登錄系統，開始搞事情 =====O(∩_∩)O哈哈~=====

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

Ubuntu

python 2.7.12

Django 1.10.4

IDE：Pycharm

Bootstrap(其實沒怎么用~~)

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

新建項目：(我是直接用pycharm直接生成的)

使用終端：

(創建項目)django-admin.py startproject mysite

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

記得在settings.py里面添加app

設計模型：

/mysite/app01/models.py：

from__future__ import unicode_literalsfromdjango.db import models

# Create your models here.classUser(models.Model):

username= models.CharField(max_length=50)

password= models.CharField(max_length=50)

email= models.EmailField()

創建User類，存放 username、password、email三個字段

同步數據庫：

Python manage.py makemigrations

python manage.py migrate

Django會自動創建一系列表

沒有自動創建superuser.......咱們手動創建：

python manage.py createsuperuser

設計邏輯視圖(views)：(使用表單)

/mysite/app01/views.py：

#coding=utf-8

fromdjango.shortcuts import render,render_to_responsefromdjango.http import HttpResponsefromdjango import formsfrommodels import User

# Create your views here.classUserForm(forms.Form):

username= forms.CharField(label='用戶名',max_length=50)

password= forms.CharField(label='密碼',widget=forms.PasswordInput())

email= forms.EmailField(label='郵箱')

def regist(request):if request.method == 'POST':

userform=UserForm(request.POST)ifuserform.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)ifuserform.is_valid():

username= userform.cleaned_data['username']

password= userform.cleaned_data['password']

user= User.objects.filter(username__exact=username,password__exact=password)ifuser:return render_to_response('index.html',{'userform':userform})else:return HttpResponse('用戶名或密碼錯誤,請重新登錄')else:

userform=UserForm()return render_to_response('login.html',{'userform':userform})

注釋:

label：標簽

widget:裝飾

widget=forms.PasswordInput():設置密碼字段

設計模板文件

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

regist.html

{% load static %}

Regist

注冊頁面

{{userform.as_p}}

login.html

{% load static %}

Login

登錄頁面

{{userform.as_p}}

index.html

主頁

Hello Word!

設計urls

/mysite/urls.py

fromdjango.conf.urls import url,includefromdjango.contrib import adminfromapp01 import urls

import app01

urlpatterns=[

url(r'^admin/', admin.site.urls),

url(r'',include(app01.urls)),

]

/mysite/app01/urls.py

fromdjango.conf.urls import url,includefromdjango.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后臺管理注冊的用戶

在models.py里面設計一個UserAdmin類，用來記錄注冊用戶的信息

/mysite/app01/models.py

from__future__ import unicode_literalsfromdjango.contrib import adminfromdjango.db import models

# Create your models here.classUser(models.Model):

username= models.CharField(max_length=50)

password= models.CharField(max_length=50)

email=models.EmailField()classUserAdmin(admin.ModelAdmin):

list_display= ('username','password','email')

admin.site.register(User,UserAdmin)

同步一下數據庫(方法同上)
