Python/Django URL

免责声明……这是一项任务！ 有人能告诉我为什么我变得越来越坚强吗

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/%7B%20%25%20url%20'detail'%20user%20%25%20%7D
Using the URLconf defined in bobbdjango.urls, Django tried these URL patterns, in this order:

[name='home']
profile [name='profile']
user_detail/<str:user_id> [name='detail']
The current path, { % url 'detail' user % }, didn’t match any of these.

You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

from django.db import models

class User(models.Model):
    first_name=models.CharField(max_length=30)
    last_name=models.CharField(max_length=30)
    email=models.EmailField()

    def __str__(self):
        return '{} {}'.format(self.first_name, self.last_name)

试试这个：

<a href="{ % url 'detail' user.id % }">

但我认为你应该改变

'user_detail/<str:user_id>'

“用户详细信息/”

作为

“用户详细信息/”

您的模板URL应如下所示：

非常感谢这一帮助谢谢您。
def home(request):
    users = User.objects.all()
    return render(request, 'home.html', {'users': users})

def userdetail(request,user_id):
    user = User.objects.get(id=user_id)
    return render(request, 'user_detail.html', {'user': user})

def profile(request):
    return render(request, 'profile.html')

from django.db import models

class User(models.Model):
    first_name=models.CharField(max_length=30)
    last_name=models.CharField(max_length=30)
    email=models.EmailField()

    def __str__(self):
        return '{} {}'.format(self.first_name, self.last_name)

<a href="{ % url 'detail' user.id % }">

'user_detail/<str:user_id>'

'user_detail/<int:user_id>'
