django 字段 'id' 需要一个数字但得到了 <built-in function id>

Question

我正在学习有关 django todoapp 的教程。我想显示所有用户的 content（他们的 todolists）并且我得到了那个错误看到标题我正在使用 google 的登录授权

这是我的 views.py

def todoView(request,):
  all_todo_items = Todoitem.objects.filter(userid=id).values_list('id', flat=True)
  return render(request, 'todoapp.html', {'all_items': all_todo_items})

这是我的 models.py

class Todoitem(models.Model):
content = models.CharField(max_length=100)
userid = models.ForeignKey(AuthUser, models.DO_NOTHING, db_column='userid', blank=True, 
null=True)

class Meta:
    managed = False
    db_table = 'todoitem'

def __str__(self):
    return self.content

class AuthUser(models.Model):
password = models.CharField(max_length=128)
username = models.CharField(unique=True, max_length=150)
first_name = models.CharField(max_length=150)
last_name = models.CharField(max_length=150)
email = models.CharField(max_length=254)

class Meta:
    managed = False
    db_table = 'auth_user'

这是我的 todoapp.html

{% load socialaccount %}
<body>
{% if user.is_authenticated %}
<p>Welcome, {{ user.username }} !</p>

{% else %}
<h1>My Google Login Project</h1>
<a href="{% provider_login_url 'google' %}">Login with Google</a>
{% endif %}
<h2>My Personal TodoApp Project</h2>
<br>
<table>
<tr>
    <th colspan="2">List of Todos</th>
</tr>
{% for todo_items in all_items %}
<tr>
    <td>{{todo_items.content}}</td>
</tr>
{% endfor %}
</table>
</body>

Answer 1

我希望 id 来自路径。所以，在你的函数中添加 id 参数：

def todoView(request, <b>id=None</b>):
  all_todo_items = Todoitem.objects.filter(userid=id).values_list('id', flat=True)
  return render(request, 'todoapp.html', {'all_items': all_todo_items})

Answer 2

您将登录用户的 Todoitem 传递给：

from django.contrib.auth.decorators import login_required

@login_required
def todoView(request):
    all_todo_items = Todoitem.objects.filter(userid=<strong>request.user</strong>)
    return render(request, 'todoapp.html', {'all_items': all_todo_items})

Note: It is normally better to make use of the settings.AUTH_USER_MODEL [Django-doc] to refer to the user model, than to use the User model [Django-doc] directly. For more information you can see the referencing the User model section of the documentation.

Note: You can limit views to a view to authenticated users with the @login_required decorator [Django-doc].
