python+django+sqlite3，不成熟的学生管理增删改查

因为是边学边做的，所以有一些地方有了很麻烦的方法，登录验证也没做完，前端也很难看，只是做了基本的增删改查

1.新建project

django-admin.py startproject student

2.新建app

python manage. py startapp guanli

3.setting设置

在

INSTALLED_APPS =

中添加新建的guanli app

4.urls设置

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('guanli/', include(('guanli.urls','guanli'), namespace='guanli'))
]

5.进入guanli app 下的models中添加数据库表

from django.db import models


class student(models.Model):
    xuehao = models.IntegerField(primary_key=True, verbose_name='学号')
    xingming = models.TextField(blank=True, null=True, verbose_name='姓名')
    xingbie = models.TextField(blank=True, null=True)
    age = models.IntegerField(blank=True, null=True, verbose_name='年龄')
    csrq = models.DateField(blank=True, null=True)
    bjbh = models.IntegerField(blank=True, null=True)
    phone = models.TextField(blank=True, null=True)
    sfzh = models.IntegerField(blank=True, null=True)

    def __int__(self):
        return self.xuehao


class teacher(models.Model):
    bianhao = models.IntegerField(primary_key=True)
    xingming = models.CharField(max_length=32)
    xingbie = models.TextField()
    csrq = models.DateField()
    zzmm = models.TextField()
    phone = models.IntegerField()
    sfzh = models.IntegerField()


class login(models.Model):
    user = models.TextField()
    password = models.TextField()

5.使用

1 python manage.py makemigrations
2 python manage.py migrate

将数据库信息添加到sqlite3中，因为是内置的所以不需要设置api

6.在guanli下的admin中添加

from django.contrib import admin
from .models import student
from .models import teacher
from .models import login


class ss(admin.ModelAdmin):
    list_display = ('xuehao', 'xingming', 'age')  # 页面显示


# list_editable = ('xingming','age')     #直接修改
# filter_horizontal = ('age',)
# list_per_page = 2       #分页
# search_fields = ('xuehao','xingming')      #查询
# list_filter = ('age','xuehao')             #辅助过滤查询
admin.site.register(student, ss)
admin.site.register(teacher)
admin.site.register(login)

在guanli 的apps中

from django.apps import AppConfig


class GuanliConfig(AppConfig):
    name = 'guanli'

7.在guanlixia的urls中

from django.urls import path
from. import views
app_name='guanli'

urlpatterns = [
    path('index/', views.index),
    path('sms/', views.stus),
    path('gon/', views.gon,name='gon'),
    path('add/', views.add,name='add'),
    path('query/', views.query,name='query'),
    path('change/', views.change,name='change'),
    path('delete/', views.delete,name='delete'),
   path('cxjg/', views.cxjg,name='cxjg'),
    path('change1/', views.change1,name='change1'),
    path('xiugai/', views.xiugai,name='xiugai'),
    path('shanchu/', views.shanchu,name='shanchu'),
    path('login/', views.login,name='login'),
    path('dele/', views.dele,name='dele'),
    path('logi/', views.logi,name='logi'),
]

8.在guanli 下的views中

from django.shortcuts import render
from django.http import HttpResponse
from .import models

def index(request):
   return render(request,'ss/index.html')

def stus(request):
   stus=models.student.objects.all()
   return render(request,'ss/stus.html',{'stus':stus})

def gon(request):
   return render(request,'ss/gon.html')

   sfzh = request.POST.get('sfzh')
   # bc = models.student()
   # bc.xuehao = xh
   # bc.xingming=xm
   # bc.xingbie=xingbie
   # bc.age=age
   # bc.csrq=csrq
   # bc.bjbh=bjbh
   # bc.phone=phone

   # bc.save()
   try:
      if (xm):
         models.student.objects.create(xuehao=xh, xingming=xm, xingbie=xingbie, age=age, csrq=csrq, bjbh=bjbh,
                                   phone=phone, sfzh=sfzh)
      return render(request, 'ss/add.html')
   except:
      aa='aa'
      return render(request, 'ss/add.html',{'aa':aa})

def query(request):
   return render(request,'ss/query.html')
def cxjg(request):
   try:
      xh=int(request.POST.get('xuehao'))
      xinxi=models.student.objects.get(pk=xh)
      quan = models.student.objects.all()
      if (xinxi in quan):
         return render(request,'ss/query.html',{'aa':xinxi})
      else:
         return render(request,'ss/query.html')
   except:
      bcz='该学号不存在'
      return render(request,'ss/query.html',{'bcz':bcz})
def change(request):
   xh = request.POST.get('xuehao')
   xinxi = models.student.objects.get(xuehao=xh)
   return render(request,'ss/change.html',{'bb':xinxi})
def xiugai(request):
   return render(request,'ss/xiugai.html')
def change1(request):
   xh = request.POST.get('xuehao1')
   obj = models.student.objects.get(xuehao=xh)
   obj.xuehao = request.POST.get('xuehao1')
   obj.xingming = request.POST.get('xingming1')
   obj.xingbie = request.POST.get('xingbie1')
   obj.age = request.POST.get('age1')
   obj.csrq = request.POST.get('csrq1')
   obj.bjbh = request.POST.get('bjbh1')
   obj.phone = request.POST.get('phone1')
   obj.sfzh = request.POST.get('sfzh1')
   obj.save()
   return render(request,'ss/gon.html')
def delete(request):
   return render(request, 'ss/delete.html')
def dele(request):
   try:
      xh=int(request.POST.get('xuehao'))
      xinxi=models.student.objects.get(pk=xh)
      quan = models.student.objects.all()
      if (xinxi in quan):
         return render(request,'ss/delete.html',{'aa':xinxi})
      else:
         return render(request,'ss/delete.html')
   except:
      bcz='该学号不存在'
      return render(request,'ss/delete.html',{'bcz':bcz})

def shanchu(request):
   xh = request.POST.get('xuehao')
   models.student.objects.get(xuehao=xh).delete()
   return HttpResponse('删除成功')
def logi(request):
   user1 = request.POST.get('user')
   password = request.POST.get('password')
   users=models.login.objects.all()
   err='用户名或密码错误'
   for user in users:
      if user.user == user1 and user.password == password:
         return render(request, 'ss/index.html')

   return render(request, 'ss/login.html',{'err':err})
def login(request):
   return render(request, 'ss/login.html')

在guanli下新建一个文件夹 Templates，在Templates中新建文件夹ss，在ss下新建html文件

添加静态文件，在student的最后加上

STATIC_URL = '/static/'
STATICFILES_DIRS = [(os.path.join(BASE_DIR, 'static'))]

在guanli下新建static文件夹，存放
