用戶名錯誤在Django中使用自定義驗證

Question

我試圖在Django中創建自定義驗證標識符是電子郵件，有一個名爲和密碼字段所需的字段。登錄視圖工作正常，但我從表單中收到錯誤username。

這裏是我的views.py

def auth_login(request): 
    if request.method == 'POST': 
     email = request.POST['email'] 
     password = request.POST['password'] 
     user = authenticate(email=email, password=password) 
     if user is not None: 
      login(request, user) 
      return HttpResponseRedirect("/tasks/") 
     else:   
      return HttpResponse('Invalid login.') 
    else: 
     form = UserCreationForm() 
    return render(request, "registration/login.html", { 
     'form': form, 
    }) 

def register(request): 
    if request.method == 'POST': 
     form = UserCreationForm(request.POST) 
     if form.is_valid(): 
      new_user = form.save() 
      new_user = authenticate(email=request.POST['email'], password=request.POST['password1']) 
      login(request, new_user) 
      return HttpResponseRedirect("/tasks/") 
    else: 
     form = UserCreationForm() 
    return render(request, "registration/register.html", { 
     'form': form, 
    }) 

這裏是我的register.html

<form class="form-signin" role="form" method="post" action=""> 
    {% csrf_token %} 
    <h2 class="form-signin-heading">Create an account</h2> 
    <input type="text" name="name" maxlength="30" class="form-control" placeholder="Username" required autofocus> 
    <br> 
    <input type="email" name="email" class="form-control" placeholder="Email" required> 
    <br> 
    <input type="password" name="password1" maxlength="4096" class="form-control" placeholder="Password" required> 
    <br> 
    <input type="password" name="password2" maxlength="4096" class="form-control" placeholder="Password confirmation" required> 
    <input type="hidden" name="next" value="/tasks/" /> 
    <br> 
    <button class="btn btn-lg btn-primary btn-block" type="submit">Create the account</button> 
</form> 

{% if form.errors %} 
    {% for error in form.errors %} 
      {{ error }}      
     {% endfor %} 
{% endif %} 

此打印錯誤username。這裏有什麼問題？

您需要創建自己的表格，而不是使用django自己的表格UserCreationForm。 Django的表單要求你有一個用戶名。

您沒有用戶名，因此Django的表單不適合您。所以...創建你自己的。另見Django 1.5: UserCreationForm & Custom Auth Model，特別是答案https://stackoverflow.com/a/16570743/27401。
