HTML

{%extends 'base.html'%} 

{% block content %} 
    <div class="container"> 

     <form method="post" class="form-signin" action="/loginvalidation/">{% csrf_token %} 
     <h2 class="form-signin-heading">Please sign in</h2> 
     <label for="inputEmail" class="sr-only">Email address</label> 
     <input type="email" id="inputEmail" class="form-control" placeholder="Email address" required autofocus> 
     <label for="inputPassword" class="sr-only">Password</label> 
     <input type="password" id="inputPassword" class="form-control" placeholder="Password" required> 
     <div class="checkbox"> 
      <label> 
      <input type="checkbox" value="remember-me"> Remember me 
      </label> 
     </div> 
     <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button> 
     </form> 

    </div> 
{% endblock %} 

HTML文件

view.py 

def loginvalidation(request): 
    print request 
    form = LoginssForm(request.POST or None) 
    print form.is_valid() 
    if form.is_valid(): 
     save_it=form.save(commit=False) 
     print save_it.email 
     save_it.save() 
     user = authenticate(username='john', password='secret') 
     if user is not None: 
    # the password verified for the user 
      if user.is_active: 
       print("User is valid, active and authenticated") 
      else: 
       print("The password is valid, but the account has been disabled!") 
     else: 
    # the authentication system was unable to verify the username and password 
      print("The username and password were incorrect.") 
    return render(request,"about-us.html",locals(), context_instance=RequestContext(request))] 

查看。 PY为我的代码

Model.py 

class LogIn(models.Model): 
    email=models.EmailField(null=False,blank=False) 
    password=models.CharField(max_length=1201,null=True,blank=True) 
    timestamp=models.DateTimeField(auto_now_add=True,auto_now=False) 
    updated=models.DateTimeField(auto_now_add=False,auto_now=True) 

应用程序的应用模型的应用 型号的型号

form.py 

    class LogInForm(forms.ModelForm): 
     class Meta: 
      model=LogIn 
      fields = '__all__' 

以上是我的表单提交代码。当我提交表单时，form.is_valid总是返回False。我刚开始学习Django，非常感谢任何帮助。

看起来您在HTML文件的字段中缺少一个“名称”属性，因此该值从未真正发布到Django。如果分别将name="email"和name="password"分别添加到字段中，则值应该通过并开始正确验证。

然而，这就是说，我同意上面的Alasdair的评论。这将是更安全，并建议使用Django的内置身份验证系统。
