Python3.6+Django2.0.2 實現使用者登入+跳轉首頁--左側選單+新增使用者資訊--展示使用者資訊

一、環境要求:

python版本:Python3.6.4

web框架:Django2.0.2

開發工具:Eclipse+Pydev

資料庫:mysql

web:html+css+JavaScript

二、實現需求:

1、使用者登入:使用者登入頁面,輸入使用者名稱、密碼(非加密),通過與資料庫比對,驗證通過後,登入成功,調整首頁

2、首頁:左側選單(粗糙)--多級選單

3、使用者管理--新增使用者--跳轉使用者新增頁面,提交資料庫

4、展示使用者資訊

三、程式碼,只貼上程式碼塊,不做詳細說明:

1、程式碼結構圖()

2、StuMan專案目錄的settings配置資訊,涉及的模組載入、路徑載入、配置資訊載入等;

"""
Django settings for StuMan project.

Generated by 'django-admin startproject' using Django 2.0.2.

https://docs.djangoproject.com/en/2.0/topics/settings/

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/2.0/howto/deployment/checklist/

DEBUG = True #允許所有host訪問 ALLOWED_HOSTS = ['*'] # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'student',#載入新增的app應用 ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] ROOT_URLCONF = 'StuMan.urls' #模板:HTML程式碼+邏輯控制程式碼 TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR,'templates')],#載入html模板路徑 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] WSGI_APPLICATION = 'StuMan.wsgi.application' # Database # https://docs.djangoproject.com/en/2.0/ref/settings/#databases #配置mysql資料庫的配置 DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'stuman', 'USER':'root', 'PASSWORD':'cecgw', 'HOST':'192.168.2.70', 'PORT':'3306', } } # Password validation # https://docs.djangoproject.com/en/2.0/ref/settings/#auth-password-validators AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] # Internationalization # https://docs.djangoproject.com/en/2.0/topics/i18n/ LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/2.0/howto/static-files/ #靜態檔案根目錄載入 STATIC_URL = '/static/' #html、css中載入css路徑、圖片路徑時,需要對映路徑 STATIC_ROOT = os.path.join(BASE_DIR, "static").replace('\\', '/') STATICFILES_DIRS =( ("css", os.path.join(STATIC_ROOT, 'css').replace('\\', '/')), ("js", os.path.join(STATIC_ROOT, 'js').replace('\\', '/')), ("imgs", os.path.join(STATIC_ROOT, 'imgs').replace('\\', '/')), )

3、StuMan專案目錄下的url配置

from django.contrib import admin
from django.urls import path
from student.views import Login,AddUser,UserMan

urlpatterns = [
    path('login/', Login.do_login,name='login'),
    path('home/', Login.home,name='home'),
    path("home/register/",AddUser.addUser,name='register'),
    path('show/',UserMan.list,name='show'),
]

4、app應用student下的model,用於建立資料庫--mysql

from django.db import models

# Create your models here.
class User(models.Model):
    username=models.CharField(max_length=20);
    password=models.CharField(max_length=20);
    email=models.EmailField(max_length=50);
    telphone=models.IntegerField();
    CreateTime=models.DateTimeField();
    Last_LoginTime=models.DateTimeField();

5、app應用student下建立一個views資料夾,用於頁面操作類

Login用於使用者登入,驗證使用者名稱和密碼與資料庫一致,然後登入跳轉首頁

#encoding:utf-8
'''

from django.shortcuts import render, redirect
from student.models import User

def home(request):  
    return render(request,'index.html')
def do_login(request):  
    if request.method == 'GET':

        return render(request, 'login.html')  
    elif request.method == "POST":

        username = request.POST.get('username', None)  
        password = request.POST.get('password', None) 
        username1=User.objects.all().values('username')[0].get('username')
        password1=User.objects.all().values('password')[0].get('password')
        if username==username1 and password==password1:
            return redirect('home')
 

AddUser用於新增使用者資訊,儲存資料庫

# -*- coding: utf-8 -*-
from django.shortcuts import render,redirect
from student import models

def addUser(request):
    if request.method=='GET':
        return render(request,'register.html')
    elif request.method == "POST":
        username = request.POST.get("username", None)
        password = request.POST.get("password", None)
        mail = request.POST.get("mail", None)
        phone = request.POST.get("phone", None)
        models.User.objects.create(username=username, password=password, email=mail, telphone=phone)
        print('展示資訊')
        return redirect('show')

UserMan用於展示使用者資訊

# -*- coding: utf-8 -*-
from django.shortcuts import render,redirect
from student import models

def list(request):
    people_list = models.User.objects.all()
    return render(request, 'show.html', {"people_list":people_list})

6、templates中html靜態檔案

    <meta charset="UTF-8">
    <title>使用者登入</title>

        }  
          
    </STYLE>
