request.session["info"] = {'id':client_object.client_id,'name':client_object.name}#获取用户id和姓名 如何更改user_info = request.session.get("info")和使其和user = User.objects.get(id=request.user.id)发挥相同作用

如果你想要让`user_info`和`user`发挥相同作用，你需要将`user_info`中的`id`值和`request.user.id`相同，这样才能获取到相同的用户信息。具体来说，你可以这样修改代码：

user_info = request.session.get("info")
if user_info:
    user = User.objects.get(id=user_info['id'])
else:
    user = None

这样，如果`request.session`中存在`info`，就会获取到`user`对象，否则`user`会被设置为`None`。同时，你需要确保在设置`request.session["info"]`时，`id`的值和`client_object.client_id`相同。这样才能保证`user_info`和`user`拥有相同的用户信息。

可以考虑优化代码的可读性和效率，例如使用列表推导式和更好的命名：

class DeliveryRequest:
    def __init__(self, name, location, time):
        self.name = name
        self.location = location
        self.time = time

class DeliveryStation:
    def __init__(self, location):
        self.location = location
        self.requests = []

    def add_request(self, request):
        self.requests.append(request)

    def match_deliveryman(self, deliverymen):
        for request in self.requests:
            matching_deliverymen = [dm for dm in deliverymen if dm.location == request.location and dm.available_time == request.time]
            for deliveryman in matching_deliverymen:
                print(f"您有一个快递将送给{request.name}，请您按时送货")
                print(f"您的快递将由{deliveryman.name}在{request.time}送达，请您按时等候")
                deliverymen.remove(deliveryman)
                break

class DeliveryMan:
    def __init__(self, name, location, available_time):
        self.name = name
        self.location = location
        self.available_time = available_time

class Dispatcher:
    def __init__(self, delivery_stations, deliverymen):
        self.delivery_stations = delivery_stations
        self.deliverymen = deliverymen

    def dispatch(self):
        for station in self.delivery_stations:
            station.match_deliveryman(self.deliverymen)

这样，我们使用列表推导式来创建了一个匹配的快递员列表，然后使用一个 for 循环来遍历它。我们也使用更好的变量名来提高代码的可读性。

from django.shortcuts import render, get_object_or_404, redirectfrom .models import StaffInfo, Emergencyfrom .forms import StaffInfoForm, EmergencyFormdef staff_info_detail(request, id): staff_info = get_object_or_404(StaffInfo, id=id) emergencies = Emergency.objects.filter(res_id=id) if request.method == 'POST': emergency_form = EmergencyForm(request.POST) if emergency_form.is_valid(): emergency = emergency_form.save(commit=False) emergency.res_id = staff_info emergency.save() return redirect('staff_info_detail', id=id) else: emergency_form = EmergencyForm() return render(request, 'staff_info_detail.html', {'staff_info': staff_info, 'emergencies': emergencies, 'emergency_form': emergency_form})def add_emergency(request, id): staff_info = get_object_or_404(StaffInfo, id=id) if request.method == 'POST': emergency_form = EmergencyForm(request.POST) if emergency_form.is_valid(): emergency = emergency_form.save(commit=False) emergency.res_id = staff_info emergency.save() return redirect('staff_info_detail', id=id) else: emergency_form = EmergencyForm() return render(request, 'add_emergency.html', {'staff_info': staff_info, 'emergency_form': emergency_form})你刚刚写的这段代码，url.py中应该怎么写？

在 `urls.py` 中，你需要添加以下代码：

from django.urls import path
from . import views

urlpatterns = [
    path('staff_info/<int:id>/', views.staff_info_detail, name='staff_info_detail'),
    path('add_emergency/<int:id>/', views.add_emergency, name='add_emergency'),
]

其中 `<int:id>` 表示这个 URL 需要一个整数参数 `id`，然后将这个参数传递给对应的视图函数。你需要将这些代码添加到你的项目中的 `urls.py` 文件中，并将 `views` 替换为你的视图文件的名称。
