部门管理

部门列表

修改myproject/myproject/urls.py

from django.contrib import admin
from django.urls import path
from employee_management import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('depart/list/', views.depart_list),
]

修改myproject/employee_management/views.py

from turtle import title
from django.shortcuts import render, redirect
from employee_management.models import Department,UserInfo

# Create your views here.
def depart_list(request):
    """部门列表"""

    depart_list = Department.objects.all()

    return render(request, "depart_list.html", {"depart_list": depart_list})

在myproject/employee_management/templates下新建depart_list.html
