视图：
from django.shortcuts import render,render_to_response, redirect
from submit import models # Create your views here. def submit(request):
if request.method == "POST":
username = request.POST.get("username", None)
password = request.POST.get("password", None)
models.UserInfo.objects.create(username=username, password=password)
user_list = models.UserInfo.objects.all()
return render(request, "submit.html", {"data": user_list}) def search(request):
#if request.method == "POST":
username = request.GET.get("username", None)
results = models.UserInfo.objects.filter(username__icontains=username) return render(request, "search.html", {"result": results}) def delete(request):
if request.method == "GET":
nid = request.GET.get("id")
models.UserInfo.objects.filter(id=nid).delete()
return render(request, "submit.html") def edit(request):
if request.method == "GET":
id = request.GET.get("id", None)
username = request.GET.get("username", None)
password = request.GET.get("password", None)
models.UserInfo.objects.filter(id=id).delete()
return render(request, "edit.html", {"username": username, "password": password})

from django.db import models # Create your models here. class UserInfo(models.Model):
username = models.CharField(max_length="")
password = models.CharField(max_length="")
