不言forward: 2019-04-15 11:03:113805browse

This article brings you an introduction to the method of using the locals() function in Django. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The locals() function will return all local variables at the current location in dictionary type.

Add in views.py

from django.shortcuts import render,HttpResponse,render_to_response
import datetime
from blog import models

def index(req):
    if req.method=="POST":
        username = req.POST.get("username")
        pwd = req.POST.get("password")

        print(username)
        print(pwd)

        if username == "klvchen" and pwd=="123":
            return HttpResponse("登录成功")
    #return render(req, "login.html")
    kl = "you are welcome"
    a = "hello"
    b = "world"
    c = "what"
    return render_to_response("new.html", locals())

Add new.html in templates

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1> {{ kl }}</h1>
<h2> {{ a }}</h2>
<h3> {{ b }}</h3>
<h4> {{ c }}</h4>
</body>
</html>

Remember to add the path in urls.py

url(r"index", views.index),
