python实现可视化大屏（django+pyechars）

1.实现效果图

2.对数据库进行迁移

python manage.py makemigrations

python manage.py migrate

3.登录页面

{% load static%}

4.设置路由

主路由

子路由

5.登录接口完整代码

def login(request):if request.method == "GET":return render(request, 'login.html')if request.method == "POST":username = request.POST.get("username")password = request.POST.get("password")print(username, password)try:# 使用 Django 自带的 authenticate 方法验证用户身份user = authenticate(request, username=username, password=password)if user:request.session["user"] = user.pkreturn redirect('pic:page')else:return redirect('pic:login')except User.DoesNotExist:messages.add_message(request, messages.WARNING, "用户名或密码错误！")return render(request, "login.html", {})

6.其他接口的完整代码
