【Django Series - 03】使用者管理模組：建立使用者、登入、退出
阿新 • • 發佈：2018-10-31
Django Series（Django2.1.2 + Anaconda3）
（一）安裝並配置 Django 環境 ||| 基於 Django 進行 Web 開發
（四）資料的增刪改：使用者提交資料，驗證資料的有效性並傳輸至後臺（jQuery.post、jQuery.getJSON）
（五）基於 "xlsxwriter + BytesIO"（Python3）生成 Excel 報表 ||| Python2 StringIO.StringIO()
說明：本系列教程根據最近實踐過程進行整理、總結和分享。由於時間和精力有限，發表時內容分析部分可能不是很完整
更新日誌：
20181019：發表第一版，主要以程式碼分享為主；知識點分析較為粗略。
知識點分析：
實現程式碼：
models.py
# -*- coding: utf-8 -*- from django.db import models from django.contrib.auth.models import User class BRsystemUser(models.Model): Users = models.OneToOneField(User, on_delete = models.CASCADE) UserName = models.CharField(max_length = 20, verbose_name = u'使用者ID') UserPWD = models.CharField(max_length = 20, verbose_name = u'使用者密碼') RoleTypeID = models.CharField(max_length = 10, verbose_name = u'使用者型別ID') #使用者型別："admin"為管理員, "general"為普通員工 NickName = models.CharField(max_length = 20, verbose_name = u'暱稱') #使用者真正名字 RegisterTime = models.DateTimeField(auto_now_add = True, verbose_name = u'註冊時間') MobilePhone = models.CharField(max_length = 11, verbose_name = u'手機號碼', null = True) #電話號碼 Note = models.CharField(default = 'None', max_length = 100, verbose_name = u'備註',null = True) def __str__(self): return self.Users.username + ' ' + self.RoleTypeID
