django之模型类在视图中的应用
一:模型类直接从把前端表单传入的值,进行存储。
@csrf_exempt def regist(request): if request.method == 'POST': form = UserForm(request.POST) # 从前端表单中获取的数据,传给用户模型类,创建实例。 username = request.POST.get('username') farm_name = request.POST.get('farm_name') address = request.POST.get('address') phone = request.POST.get('phone') if form.is_valid(): user = form.save() # 验证成功 #将用户信息(id, nickname, photo)保存到session中 request.session['login_user'] = json.dumps({'id': user.id, 'nickname': user.nickname }) cowObj = Sheep_Farm.objects.filter(farm_name=farm_name) if cowObj.count() != 0: user_id = cowObj[0].user_id else: user_id = UserProfile.objects.get(username=username).id Sheep_Farm.objects.create( username=username, farm_name=farm_name, address=address, phone=phone, user_id=int(user_id), ) return JsonResponse({'message': '注册成功!', 'session': request.session['login_user']}) else: errors = json.loads(form.errors.as_json()) messages = [error for error in errors] message = errors[messages[0]][0]['message'] return JsonResponse({'message': message,'status':'0'})
