问题描述

在我的本地主机(127.0.0.1:8000)上,我配置了一个登录页面,登录后它不会重定向到“自动化页面(form_name_view”)。

注意:-当我单击登录按钮时,无论使用正确的凭据还是错误的,都不会发生任何事情。

在views.py

from django.contrib.auth import authenticate,login,logout
# Create your views here.

def login_view(request):
    context = {}
    if request.method == "post":
        username = request.post['username']
        password = request.post['password']

        user = authenticate(request, username=username, password=password)
        if user:
            login(request, user)
            return HttpResponseRedirect(reverse('IP form'))
        else:
            context["error"] = "Provide valid credentials"
            return render (request,"first_app/login.html", context)
    else:
        return render (request,"first_app/login.html", context)


def form_name_view(request):              #this is the view to which i want to redirect
    if request.method == "POST":
  #some code

在模型.py

from django.db import models
from django.contrib.auth.models import User

# Create your models here.
class Login(models.Model):



    username = models.CharField(max_length=50,)  
    password = models.CharField(max_length=32,)


    def __str__(self):                               
        return self.user.Username       

在 admin.py

from django.contrib import admin
from first_app.models import Login

# Register your models here.
admin.site.register(Login)

在 login.html 中

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Login</title>
  </head>
  <body>



    <h1> Please Login</h1>
    <form method="post">
        {% csrf_token %}
        <table>
          <tr>
            <td><label for="username">Enter username: </label></td>
            <td><input type="text" name="username" id="username" required></td>
          </tr>

          <tr>
            <td><label for="username">Enter password: </label></td>
            <td><input type="password" name="password" id="password" required></td>
          </tr>
          <p> {{ error }} </p>
        </table>
        <input type="submit"  value="LOGIN"/>
          </form>
  </body>
</html>

在 urls.py

from django.contrib import admin
from django.urls import path
from django.conf.urls import include
from first_app import views

urlpatterns = [
    path('Automation_page/', views.form_name_view,name='IP form'),
    path('admin/', admin.site.urls),
    path('',views.login_view,name='login'),
    path('first_app/',include('first_app.urls')),

    ]

我想要的是:- A)只有用户名在 db 中的用户才能访问自动化页面(form_name_view)

B)当用户登录并成功时,必须将其重定向到自动化页面(form_name_view),否则页面会显示错误消息并停留在登录页面上。

提前谢谢

解决方案


您需要注意字符串和变量的大小写。POST在 django 中大写:

  • 它是if request.method == 'POST'
  • 它是username = request.POST['username']
