Pycharm+django2.2+python3.6+MySQL實現簡單的考試報名系統

這篇文章主要介紹了Pycharm+django2.2+python3.6+MySQL實現簡單的考試報名系統,本文圖文並茂給大家介紹的非常詳細，具有一定的參考借鑑價值,需要的朋友可以參考下

1 準備工作

1.1 環境搭建

1.1.1 安裝python3.6

python安裝官網

1.1.2 安裝django2.2

pip install django(==2.2.0) //不加版本默認安裝最新版

1.1.3 安裝pycharm（社區版，官網下載安裝即可）

在安裝完成後要配置好需要的第三方庫：（pip下載，推薦在pycharm下也配置虛擬環境）

Django2.2

連接mysql需要的庫：PyMySQL, mysql, mysqlclinet

驗證碼用到的庫：django-simple-captcha（只需在虛擬環境下配置）

（由於下載庫較多，忘記用到的庫，下附截圖）

1.1.4 安裝數據庫，

我使用的是MySQL,推薦安裝界面管理文件（我使用的是MySQLWorkbench）數據庫配置，settings.py文件

DATABASES = {
 'default': {
 'ENGINE': 'django.db.backends.mysql',
 'NAME':'cet',    #數據庫名字
 'USER':'root',   #登陸數據庫的用戶名
 'PASSWORD':'123',   #登陸數據庫的密碼
 'HOST':'localhost',   #數據庫的ip地址
 'PORT':'3306',   #ip地址的端口號，默認（3306）
 }
}

__init__.py裏面導入pymysql

import pymysql pymysql.install_as_MySQLdb()

1.2 創建django項目及app

1.2.1 創建指令

django-admin startproject project_name #創建項目
python manage.py startapp app_name  #創建app(可能會報錯)
#上面創建app失敗用下面這個指令
django-admin startapp app_name 
 1.2.2 註冊app
INSTALLED_APPS = [
 'django.contrib.admin',  
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'login',   #登錄註冊
 'captcha',  #驗證碼
 'home',   #報名主頁
]

1.4 更改時區和語言

settings.py文件中，將默認改爲亞洲/上海和中文

LANGUAGE_CODE = 'zh-hans'
TIME_ZONE = 'Asia/Shanghai'
USE_I18N = True
USE_L10N = True
USE_TZ = False

1.5 數據庫遷移

更改models.py後，要將更改同步到數據庫之中，這時就要用到數據庫遷移指令（若遷移失敗：no changes問題）。

python manage.py makemigrations
python manage.py migrate

1.6 創建超級管理員

命令行衝使用指令創建管理員賬號用於使用django自帶的框架。

python manage.py createsuperuser

1.7 運行準備

添加端口號：

2 註冊登錄模塊

(我將其放在了app名爲login裏面)

2.1 數據庫模型設計

特殊參數說明：verbose_name——用於修改django框架各表成員的名字（相當於副名，只用於顯示），其他可以從文章

開頭推薦的博客瞭解。

#login/models.py
from django.db import models
# Create your models here.
class User(models.Model):
 '''用戶表'''
 gender = (
 ('male', '男'),
 ('female', '女'),
 )
 name = models.CharField(verbose_name="用戶名", max_length=128, unique=True) # unique表示唯一
 password = models.CharField(verbose_name="密碼", max_length=256)
 email = models.EmailField(verbose_name="郵箱", unique=True)
 sex = models.CharField(verbose_name="性別", max_length=32, choices=gender, default='男')
 c_time = models.DateTimeField(auto_now_add=True)
 def __str__(self):
 return self.name
 #用於將django自帶管理員端漢化
 class Meta:
 ordering = ['c_time']
 verbose_name = '用戶'
 verbose_name_plural = '用戶'

2.2 在admin中註冊模型

#login/admin.py
from django.contrib import admin
# Register your models here.
from . import models
admin.site.register(models.User)

2.3 創建表單

在我們創建數據庫用戶表後,採用表單驗證前端的數據並進行存儲到數據庫中。

#login/forms.py
from django import forms
from captcha.fields import CaptchaField
class user_entry(forms.Form):
 user_name = forms.CharField(label="用戶名", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
 user_true_name = forms.CharField(label="真實姓名", max_length=128,widget=forms.TextInput(attrs={'class': 'form-control'}))
 user_id = forms.CharField(label="身份證號", max_length=18, widget=forms.TextInput(attrs={'class': 'form-control'}))
 email = forms.EmailField(label="郵箱地址", widget=forms.EmailInput(attrs={'class': 'form-control'}))
 exam_point = forms.CharField(label="考點", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
class user_datas(forms.Form):
 email = forms.EmailField(label="郵箱地址", widget=forms.EmailInput(attrs={'class': 'form-control'}))
 user_name = forms.CharField(label="用戶名", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
 user_true_name = forms.CharField(label="真實姓名", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
 user_id = forms.CharField(label="身份證號", max_length=18, widget=forms.TextInput(attrs={'class': 'form-control'}))
 # user_img =
 user_school = forms.CharField(label="所在學校", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
 # user_f_score = forms.CharField(label="四級成績", max_length=10, widget=forms.TextInput(attrs={'class': 'form-control'}))
 # user_s_score = forms.CharField(label="六級成績", max_length=10, widget=forms.TextInput(attrs={'class': 'form-control'}))

2.4 路由及視圖設計

2.4.1 路由設計

由於登陸註冊使用的路徑不多，就將其全放在項目目錄下的urls.py文件，當然也可以採用項目和app相結合。

#項目名/urls.py
from django.contrib import admin
from django.urls import path,include
from login import views
urlpatterns = [
 path('', views.index),  #修改端口默認主頁
 path('admin/', admin.site.urls), #管理員端
 #登錄註冊
 path('index/', views.index),
 path('check/', views.check),
 path('login/', views.login),
 path('register/', views.register),
 path('logout/', views.logout),
 #使用驗證碼
 path('captcha', include('captcha.urls')),
 #報名app路由
 path('homepage/',include('home.urls')),
]

2.4.2 試圖設計

#login/views.py
from django.shortcuts import render, redirect
from . import models
from .forms import UserForm,RegisterForm
from home.models import user_data
# Create your views here.
def check(request):
 pass
 return render(request, 'login/hello.html')
def index(request):
 pass
 return render(request, 'login/index.html')
#加入sesson
def login(request):
 #不允許重複登錄
 if request.session.get('is_login', None):
 return redirect('/index')
 if request.method == "POST":
 login_form = UserForm(request.POST)
 message = "請檢查填寫的內容！"
 if login_form.is_valid():
  username = login_form.cleaned_data['username']
  password = login_form.cleaned_data['password']
  try:
  user = models.User.objects.get(name=username)
  if user.password == password:
   #往session字典內寫入用戶狀態和數據
   request.session['is_login'] = True
   request.session['user_id'] = user.id
   request.session['user_name'] = user.name
   return redirect('/index/')
  else:
   message = "密碼不正確！"
  except:
  message = "用戶不存在！"
 return render(request, 'login/login.html', locals())
 login_form = UserForm()
 return render(request, 'login/login.html', locals())
def logout(request):
 if not request.session.get('is_login', None):
 # 如果本來就未登錄，也就沒有登出一說
 return redirect("/index/")
 request.session.flush()
 # 或者使用下面的方法
 # del request.session['is_login']
 # del request.session['user_id']
 # del request.session['user_name']
 return redirect("/index/")
def register(request):
 if request.session.get('is_login', None):
 # 登錄狀態不允許註冊。
 return redirect("/index/")
 if request.method == "POST":
 register_form = RegisterForm(request.POST)
 message = "請檢查填寫的內容！"
 if register_form.is_valid(): # 獲取數據
  username = register_form.cleaned_data['username']
  password1 = register_form.cleaned_data['password1']
  password2 = register_form.cleaned_data['password2']
  email = register_form.cleaned_data['email']
  sex = register_form.cleaned_data['sex']
  if password1 != password2: # 判斷兩次密碼是否相同
  message = "兩次輸入的密碼不同！"
  return render(request, 'login/register.html', locals())
  else:
  same_name_user = models.User.objects.filter(name=username)
  if same_name_user: # 用戶名唯一
   message = '用戶已經存在，請重新選擇用戶名！'
   return render(request, 'login/register.html', locals())
  same_email_user = models.User.objects.filter(email=email)
  if same_email_user: # 郵箱地址唯一
   message = '該郵箱地址已被註冊，請使用別的郵箱！'
   return render(request, 'login/register.html', locals())
  message = "註冊成功！"
  # 當一切都OK的情況下，創建新用戶
  # 創建用戶信息//有問題：放在創建用戶表後面會出現DJANGO pymysql.err.IntegrityError:
  # (1062, "Duplicate entry '' for key 'user_name'")
  new_user_data = user_data.objects.create()
  new_user_data.user_name = username
  new_user_data.user_true_name = '無'
  new_user_data.user_id = '無'
  new_user_data.user_school = '無'
  # new_user_data.user_f_score = 425
  # new_user_data.user_s_score = 0
  new_user_data.save()
  #創建用戶表
  new_user = models.User.objects.create()
  new_user.name = username
  new_user.password = password1
  new_user.email = email
  new_user.sex = sex
  new_user.save()
  return redirect('/login/') # 自動跳轉到登錄頁面
 register_form = RegisterForm()
 return render(request, 'login/register.html', locals())

3 個人信息及報名管理

(我將其放在了app名爲home裏面)

3.1 數據庫模型設計

#home/models.py
from django.db import models
# Create your models here.
class exam_entry_table(models.Model):
 #考點信息表
 exam_id = models.CharField(verbose_name="考試編號",max_length=10)
 exam_type = models.CharField(verbose_name="考試類別",max_length=128)
 exam_point = models.CharField(verbose_name="考點",max_length=128)
 exam_time = models.CharField(verbose_name="考試時間",max_length=128)
 number = models.IntegerField(verbose_name="容量")
 entry_number = models.IntegerField(verbose_name="已報名數量",default=0)
 def __str__(self):
 return self.exam_point
 class Meta:
 # ordering = ['c_time']
 verbose_name = '考點'
 verbose_name_plural = '考點信息表'
class user_entry_table(models.Model):
 #用戶考試信息表
 email = models.EmailField(verbose_name="郵箱")
 exam_id = models.CharField(verbose_name="考試編號",max_length=10)
 exam_point = models.CharField(verbose_name="考點",max_length=128)
 def __str__(self):
 return self.email
 class Meta:
 # ordering = ['c_time']
 verbose_name = '用戶考試信息'
 verbose_name_plural = '用戶考試信息表'
class user_data(models.Model):
 #用戶信息表
 user_name = models.CharField(verbose_name="用戶名",max_length=128, unique=True)
 user_true_name = models.CharField(verbose_name="真實姓名",max_length=128, null=True)
 user_id = models.CharField(verbose_name="身份證號",max_length=18, null=True)
 # user_img =
 user_school = models.CharField(verbose_name="在讀學校",max_length=128)
 user_f_score = models.IntegerField(verbose_name="四級成績", default=0)
 user_s_score = models.IntegerField(verbose_name="六級成績", default=0)
 def __str__(self):
 return self.user_name
 class Meta:
 # ordering = ['c_time']
 verbose_name = '用戶名'
 verbose_name_plural = '用戶信息表'

3.2 註冊模型

#home/admin.py
from django.contrib import admin
# Register your models here.
from . import models
admin.site.register(models.exam_entry_table) #考點信息表
admin.site.register(models.user_entry_table) #用戶考試信息表
admin.site.register(models.user_data)  #用戶信息表

3.3 創建表單

#home/forms.py
from django import forms
from captcha.fields import CaptchaField
class UserForm(forms.Form):
 username = forms.CharField(label="用戶名", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
 password = forms.CharField(label="密碼", max_length=256, widget=forms.PasswordInput(attrs={'class': 'form-control'}))
 captcha = CaptchaField(label='驗證碼')
class RegisterForm(forms.Form):
 gender = (
  ('male', "男"),
  ('female', "女"),
 )
 username = forms.CharField(label="用戶名", max_length=128, widget=forms.TextInput(attrs={'class': 'form-control'}))
 password1 = forms.CharField(label="密碼", max_length=256, widget=forms.PasswordInput(attrs={'class': 'form-control'}))
 password2 = forms.CharField(label="確認密碼", max_length=256, widget=forms.PasswordInput(attrs={'class': 'form-control'}))
 email = forms.EmailField(label="郵箱地址", widget=forms.EmailInput(attrs={'class': 'form-control'}))
 sex = forms.ChoiceField(label='性別', choices=gender)
 captcha = CaptchaField(label='驗證碼')

3.4 路由及視圖設計

3.4.1 路由設計

這裏用到的路勁較爲複雜，採用項目urls和app的urls結合起來避免項目的urls過於擁擠。

先修改項目的urls.py文件：

#項目名/urls.py
path('homepage/',include('home.urls')), #前面已經添加了，這裏只做說明

再修改app中的urls.py文件：

#home/urls.py
from django.contrib import admin
from django.urls import path,include
from home import views
urlpatterns = [
 path('test/', views.test),
 path('my_data/',views.mydate),   #我的信息
 path('query_results/',views.query), #查詢報告信息
 path('cet_4/',views.cet_4),   #四級報名
 path('cet_6/',views.cet_6),   #六級報名
 path('change_my_data/',views.updata),
]

3.4.2 試圖設計

#home/views.py
from django.shortcuts import render, redirect
from . import models
from .forms import user_entry, user_datas
from django.http import HttpResponse,HttpResponseRedirect
# from django.contrib.auth.models import User
from login.models import User
# Create your views here.
def test(request):
 pass
 return render(request, 'home/test.html')
#我的信息
def mydate(request):
 username = request.session.get('user_name', None)
 account = User.objects.get(name=username)#用戶登錄註冊表
 user = models.user_data.objects.get(user_name= username)
 return render(request,"home/myself.html",{"user":user, "account":account})
#修改我的信息
def updata(request):
 username = request.session.get('user_name', None)
 # print("-----------------------")
 # print(username)
 # print("-----------------------")
 user_da = models.user_data.objects.get(user_name=username)
 user = User.objects.get(name=username)#login_user表
 if request.method == "POST":
  userdata = user_datas(request.POST)
  # print(userdata)
  if userdata.is_valid():
   user_das = userdata.cleaned_data
   # user.user_name = user_da['user_name'] #用戶無法修改用戶名
   user.email = user_das['email']
   user_da.user_true_name = user_das['user_true_name']
   user_da.user_id = user_das['user_id']
   user_da.user_school = user_das['user_school']
   user_da.save()
   user.save()
   # 四六級成績無法修改
   # user_datas.user_f_score = user_da['user_f_score']
   # user_datas.user_s_score = user_da['user_s_score']
   return redirect('/homepage/my_data/')
 else:
  userdata = user_datas(initial={"email":user.email,"user_name":user_da.user_name,"user_true_name":user_da.user_true_name,"user_id":user_da.user_id,"user_school":user_da.user_school})
  return render(request, 'home/change_mydata.html', {"userdata":userdata})
#查詢考試信息 還沒完成，優化，條件判斷
def query(request):
 username = request.session.get('user_name',None)
 user = User.objects.get(name=username)
 #用於判斷用戶是否報名
 user_en = models.user_entry_table.objects.filter(email=user.email)
 # print("********************")
 # print(user_en)

     "user_id": user_da.user_id})
 return render(request, 'home/cet_6.html', locals())

到這裏基本的後端都實現了。

數據庫設計問題:

由於此次設計在開始之時沒有設計完善，數據庫各表之間的關聯存在問題，例如本次報名系統而言，用戶信息最好添加手機號碼，我本打算使用郵箱即可，但是推薦使用聯繫更快的電話號碼等等問題。
