如何在django 2.0的detailview中使用

class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
name = models.CharField(max_length=40, blank=True)
bio = models.TextField(max_length=500, null=True, blank=True)

def get_absolute_url(self):
    return reverse('userprofile:to_profile', args=[str(self.user.username)])

所以我把这个模型保存为whatever.com/userprofile:to_profile/thisisusername

在网址上,我有

    path('accounts/profile/<username>/', ProfileDetailView.as_view(), name="to_profile"),

对于观点,我有

class ProfileDetailView(DetailView):
model = Profile
template_name = "account/profile.html"

我知道默认的DetailView需要pk和slug,但每当我尝试传递用户名时

pk_url_kwarg = "username"

我收到一个错误

invalid literal for int() with base 10

反正我们可以使用用户名进行通用详细视图吗？还是pk唯一的出路？

首先将您的网址更改为：

path('accounts/profile/<str:slug>/', ProfileDetailView.as_view(), name="to_profile"),

第二步定义获取SlugField的方法

class ProfileDetailView(DetailView):
    model = Profile
    template_name = "account/profile.html"

    def get_slug_field(self):
    """Get the name of a slug field to be used to look up by slug."""
        return 'user__username'
