Question

我目前正在通过以下教程：https://www.tutorialspoint.com/django/django_form_processing.htm

我是django的新手，之前的教程是我在django中唯一的体验，因此显然没什么可说的。当我尝试使用表单登录时，收到消息：您是：未登录，但是我应用的登录凭据与我在教程开头创建超级用户时应用的相同，所以我觉得他们应该有效。这是我的文件：

forms.py

from django import forms

class LoginForm(forms.Form):

    user = forms.CharField(max_length = 100)
    password = forms.CharField(max_length = 100)

的login.html

<html>
   <body>

      <form name = "form" action = "{% url "login" %}"
         method = "POST" >{% csrf_token %}

         <div style = "max-width:470px;">
            <center>
               <input type = "text" style = "margin-left:20%;"
                  placeholder = "Identifiant" name = "username" />
            </center>
         </div>

         <br>

         <div style = "max-width:470px;">
            <center>
               <input type = "password" style = "margin-left:20%;"
                  placeholder = "password" name = "password" />
            </center>
         </div>

         <br>

         <div style = "max-width:470px;">
            <center>

               <button style = "border:0px; background-color:#4285F4; margin-top:8%;
                  height:35px; width:80%;margin-left:19%;" type = "submit"
                  value = "Login" >
                  <strong>Login</strong>
               </button>

            </center>
         </div>

      </form>

   </body>
</html>

urls.py （在myapp文件夹中）

from django.conf.urls import url
from django.views.generic import ListView, TemplateView
from myapp.views import hello, viewArticle, crudops, login
from myapp.models import Dreamreal

urlpatterns = [

    url(r'^hello/', hello, name = 'hello'),
    url(r'^article/(\d+)/', viewArticle, name = 'article'),
    url(r'^crudops/', crudops, name = "crudops"),
    url(r'^dreamreals/', ListView.as_view(model = Dreamreal, template_name = "dreamreal_list.html")),
    url(r'^connection/', TemplateView.as_view(template_name = "login.html")),
    url(r'^login/', login, name = 'login'),


]

views.py

from django.shortcuts import render
from django.http import HttpResponse
from myapp.models import Dreamreal
import datetime
from myapp.forms import LoginForm

def hello(request):

    today = datetime.datetime.now().date()
    return render(request, "hello.html", {"today":today, "days": ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"]})

def viewArticle(request, articleId):

    text = "Displaying article: %s " %articleId
    return HttpResponse(text)

def crudops(request):

    #Read All Entries

    objects = Dreamreal.objects.all()
    text = "Here are all the entries in the Dreamreal Database"

    for obj in objects:
        text += "<br/>" + obj.website + ", " + obj.name + "<br/>"

    return HttpResponse(text)

def login(request):

    username = "Not Logged In"

    if request.method == "POST":
        MyLoginForm = LoginForm(request.POST)

        if MyLoginForm.is_valid():
            username = MyLoginForm.cleaned_data["username"]

    else:

        MyLoginForm = LoginForm()

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

非常感谢任何帮助。

表单和模板上的字段名称需要匹配。因为你有

<input type = "text" style = "margin-left:20%;"
 placeholder = "Identifiant" name = "username" />

使用name = username，您需要确保您的表单使用该字段名称。

class LoginForm(forms.Form):

    username = forms.CharField(max_length = 100)
    password = forms.CharField(max_length = 100)

如何将django表单提交从一个页面转移到另一个页面？
