pyhton使用django实现简单的增删改查

from django.shortcuts import render,redirect,HttpResponse
from app01.models import Dep
# Create your views here.

def dep_list(request):
    list=Dep.objects.all()
    return render(request,"dep_list.html",{'list':list})

def to_dep_add(request):
    id=request.GET.get('id')
    if id:
        obj=Dep.objects.filter(id=id).first()
        return render(request,"dep_add.html" ,{'obj':obj})
    return render(request,"dep_add.html" )

def dep_save(request):
    dname=request.POST.get('dname')
    id=request.POST.get('id')
    print(id,'-'*100)
    if id:
        Dep.objects.filter(id=id).update(dname=dname)
    else:
        Dep.objects.create(dname=dname)
    return redirect('/dep/list')


def dep_del(request,id):
    Dep.objects.filter(id=id).delete()
    return redirect('/dep/list')

# path('dep/del/<int:id>', app01views.dep_del ),urls.xml里这样配置参数
